  10. Because so many people (myself included) seem to have obtained ARCnet cards
  11. without manuals, this file contains a quick introduction to ARCnet hardware,
  12. some cabling tips, and a listing of all jumper settings I can find. Please
  13. e-mail apenwarr@foxnet.net with any settings for your particular card, or
  14. any other information you have!

  17. INTRODUCTION TO ARCNET
  18. ----------------------
  19.  
  20. ARCnet is a network type which works in a way similar to popular Ethernet
  21. networks but which is also different in some very important ways.
  22.  
  23. First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
  24. (slower than Ethernet) and 100 Mbps (faster than normal Ethernet).  In fact,
  25. there are others as well, but these are less common.  The different hardware
  26. types, as far as I'm aware, are not compatible and so you cannot wire a
  27. 100 Mbps card to a 2.5 Mbps card, and so on.  From what I hear, my driver does
  28. work with 100 Mbps cards, but I haven't been able to verify this myself,
  29. since I only have the 2.5 Mbps variety.  It is probably not going to saturate
  30. your 100 Mbps card.  Stop complaining :)
  31.  
  32. You also cannot connect an ARCnet card to any kind of Ethernet card and
  33. expect it to work.  
  34.  
  35. There are two "types" of ARCnet - STAR topology and BUS topology.  This
  36. refers to how the cards are meant to be wired together.  According to most
  37. available documentation, you can only connect STAR cards to STAR cards and
  38. BUS cards to BUS cards.  That makes sense, right?  Well, it's not quite
  39. true; see below under "Cabling."
  40.  
  41. Once you get past these little stumbling blocks, ARCnet is actually quite a
  42. well-designed standard.  It uses something called "modified token passing"
  43. which makes it completely incompatible with so-called "Token Ring" cards,
  44. but which makes transfers much more reliable than Ethernet does.  In fact,
  45. ARCnet will guarantee that a packet arrives safely at the destination, and
  46. even if it can't possibly be delivered properly (ie. because of a cable
  47. break, or because the destination computer does not exist) it will at least
  48. tell the sender about it.
  49.  
  50. Because of the carefully defined action of the "token", it will always make
  51. a pass around the "ring" within a maximum length of time.  This makes it
  52. useful for realtime networks.
  53.  
  54. In addition, all known ARCnet cards have an (almost) identical programming
  55. interface.  This means that with one "arcnet" driver you can support any
  56. card; whereas, with Ethernet, each manufacturer uses what is sometimes a
  57. completely different programming interface, leading to a lot of different,
  58. sometimes very similar, Ethernet drivers.  Of course, always using the same
  59. programming interface also means that when high-performance hardware
  60. facilities like PCI busmastering DMA appear, it's hard to take advantage of
  61. them.  Let's not go into that.
  62.  
  63. One thing that makes ARCnet cards difficult to program for, however, is the
  64. limit on their packet sizes; standard ARCnet can only send packets that are
  65. up to 508 bytes in length.  This is smaller than the internet "bare minimum"
  66. of 576 bytes, let alone the Ethernet MTU of 1500.  To compensate, an extra
  67. level of encapsulation is defined by RFC1201, which I call "packet
  68. splitting," that allows "virtual packets" to grow as large as 64K each,
  69. although they are generally kept down to the Ethernet-style 1500 bytes.
  70.  
  71. For more information on the advantages and disadvantages (mostly the
  72. advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

  77. CABLING ARCNET NETWORKS
  78. -----------------------
  79.  
  80. This section was rewritten by
  81.         Vojtech Pavlik     <Vojtech.Pavlik@st.mff.cuni.cz>
  82. using information from several people, including:
  83.         Avery Pennraun     <apenwarr@foxnet.net>
  84.         Stephen A. Wood    <saw@hallc1.cebaf.gov>
  85.         John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
  86.         Joachim Koenig     <jojo@repas.de>
  87. and Avery touched it up a bit, at Vojtech's request.
  88.  
  89. ARCnet (the classic 2.5 Mbps version) can be connected by two different
  90. types of cabling: coax and twisted pair.  The other ARCnet-type networks
  91. (100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
  92. cabling (Type1, Fiber, C1, C4, C5).
  93.  
  94. For a coax network, you "should" use 93 Ohm RG-62 cable.  But other cables
  95. also work fine, because ARCnet is a very stable network. I personally use 75
  96. Ohm TV antenna cable.
  97.  
  98. Cards for coax cabling are shipped in two different variants: for BUS and
  99. STAR network topologies.  They are mostly the same.  The only difference
  100. lies in the hybrid chip installed.  BUS cards use high impedance output,
  101. while STAR use low impedance.  Low impedance card (STAR) is electrically
  102. equal to a high impedance one with a terminator installed.
  103.  
  104. Usually, the ARCnet networks are built up from STAR cards and hubs.  There
  105. are two types of hubs - active and passive.  Passive hubs are small boxes
  106. with four BNC connectors containing four 47 Ohm resistors:
  107.  
  108.    |         | wires
  109.    R         + junction
  110. -R-+-R-      R 47 Ohm resistors
  111.    R
  112.    |
  113.  
  114. The shielding is connected together.  Active hubs are much more complicated;
  115. they are powered and contain electronics to amplify the signal and send it
  116. to other segments of the net.  They usually have eight connectors.  Active
  117. hubs come in two variants - dumb and smart.  The dumb variant just
  118. amplifies, but the smart one decodes to digital and encodes back all packets
  119. coming through.  This is much better if you have several hubs in the net,
  120. since many dumb active hubs may worsen the signal quality.
  121.  
  122. And now to the cabling.  What you can connect together:
  123.  
  124. 1. A card to a card.  This is the simplest way of creating a 2-computer
  125.    network.
  126.  
  127. 2. A card to a passive hub.  Remember that all unused connectors on the hub
  128.    must be properly terminated with 93 Ohm (or something else if you don't
  129.    have the right ones) terminators.
  130.         (Avery's note: oops, I didn't know that.  Mine (TV cable) works
  131.         anyway, though.)
  132.  
  133. 3. A card to an active hub.  Here is no need to terminate the unused
  134.    connectors except some kind of aesthetic feeling.  But, there may not be
  135.    more than eleven active hubs between any two computers.  That of course
  136.    doesn't limit the number of active hubs on the network.
  137.    
  138. 4. An active hub to another.
  139.  
  140. 5. An active hub to passive hub.
  141.  
  142. Remember, that you can not connect two passive hubs together.  The power loss
  143. implied by such a connection is too high for the net to operate reliably.
  144.  
  145. An example of a typical ARCnet network:
  146.  
  147.            R                     S - STAR type card              
  148.     S------H--------A-------S    R - Terminator
  149.            |        |            H - Hub                        
  150.            |        |            A - Active hub                  
  151.            |   S----H----S                                      
  152.            S        |                                            
  153.                     |                                            
  154.                     S                                            
  155.                                                                          
  156. The BUS topology is very similar to the one used by Ethernet.  The only
  157. difference is in cable and terminators: they should be 93 Ohm.  Ethernet
  158. uses 50 Ohm impedance. You use T connectors to put the computers on a single
  159. line of cable, the bus. You have to put terminators at both ends of the
  160. cable. A typical BUS ARCnet network looks like:
  161.  
  162.     RT----T------T------T------T------TR
  163.      B    B      B      B      B      B
  164.  
  165.   B - BUS type card
  166.   R - Terminator
  167.   T - T connector
  168.  
  169. But that is not all! The two types can be connected together.  According to
  170. the official documentation the only way of connecting them is using an active
  171. hub:
  172.  
  173.          A------T------T------TR
  174.          |      B      B      B
  175.      S---H---S
  176.          |
  177.          S
  178.  
  179. The official docs also state that you can use STAR cards at the ends of
  180. BUS network in place of a BUS card and a terminator:
  181.  
  182.      S------T------T------S
  183.             B      B
  184.  
  185. But, according to my own experiments, you can simply hang a BUS type card
  186. anywhere in middle of a cable in a STAR topology network.  And more - you
  187. can use the bus card in place of any star card if you use a terminator. Then
  188. you can build very complicated networks fulfilling all your needs!  An
  189. example:
  190.  
  191.                                   S
  192.                                   |
  193.            RT------T-------T------H------S
  194.             B      B       B      |
  195.                                   |       R
  196.     S------A------T-------T-------A-------H------TR                    
  197.            |      B       B       |       |      B                        
  198.            |   S                 BT       |                                
  199.            |   |                  |  S----A-----S
  200.     S------H---A----S             |       |
  201.            |   |      S------T----H---S   |
  202.            S   S             B    R       S  
  203.                                                                
  204. A basically different cabling scheme is used with Twisted Pair cabling. Each
  205. of the TP cards has two RJ (phone-cord style) connectors.  The cards are
  206. then daisy-chained together using a cable connecting every two neighboring
  207. cards.  The ends are terminated with RJ 93 Ohm terminators which plug into
  208. the empty connectors of cards on the ends of the chain.  An example:
  209.  
  210.           ___________   ___________
  211.       _R_|_         _|_|_         _|_R_  
  212.      |     |       |     |       |     |      
  213.      |Card |       |Card |       |Card |    
  214.      |_____|       |_____|       |_____|          
  215.  
  216.  
  217. There are also hubs for the TP topology.  There is nothing difficult
  218. involved in using them; you just connect a TP chain to a hub on any end or
  219. even at both.  This way you can create almost any network configuration.
  220. The maximum of 11 hubs between any two computers on the net applies here as
  221. well.  An example:
  222.  
  223.     RP-------P--------P--------H-----P------P-----PR
  224.                                |
  225.       RP-----H--------P--------H-----P------PR
  226.              |                 |
  227.              PR                PR
  228.  
  229.     R - RJ Terminator
  230.     P - TP Card
  231.     H - TP Hub
  232.  
  233. Like any network, ARCnet has a limited cable length.  These are the maximum
  234. cable lengths between two active ends (an active end being an active hub or
  235. a STAR card).
  236.  
  237.                 RG-62       93 Ohm up to 650 m
  238.                 RG-59/U     75 Ohm up to 457 m
  239.                 RG-11/U     75 Ohm up to 533 m
  240.                 IBM Type 1 150 Ohm up to 200 m
  241.                 IBM Type 3 100 Ohm up to 100 m
  242.  
  243. The maximum length of all cables connected to a passive hub is limited to 65
  244. meters for RG-62 cabling; less for others.  You can see that using passive
  245. hubs in a large network is a bad idea. The maximum length of a single "BUS
  246. Trunk" is about 300 meters for RG-62. The maximum distance between the two
  247. most distant points of the net is limited to 3000 meters. The maximum length
  248. of a TP cable between two cards/hubs is 650 meters.
  249.  
  250.  
  251. SETTING THE JUMPERS
  252. -------------------
  253.  
  254. All ARCnet cards should have a total of four or five different settings:
  255.  
  256.   - the I/O address:  this is the "port" your ARCnet card is on.  Probed
  257.     values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
  258.     your card has additional ones, which is possible, please tell me.) This
  259.     should not be the same as any other device on your system.  According to
  260.     a doc I got from Novell, MS Windows prefers values of 0x300 or more,
  261.     eating net connections on my system (at least) otherwise.  My guess is
  262.     this may be because, if your card is at 0x2E0, probing for a serial port
  263.     at 0x2E8 will reset the card and probably mess things up royally.
  264.         - Avery's favourite: 0x300.
  265.  
  266.   - the IRQ: on  8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
  267.              on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
  268.              
  269.     Make sure this is different from any other card on your system.  Note
  270.     that IRQ2 is the same as IRQ9, as far as Linux is concerned.  You can
  271.     "cat /proc/interrupts" for a somewhat complete list of which ones are in
  272.     use at any given time.  Here is a list of common usages from Vojtech
  273.     Pavlik <Vojtech.Pavlik@st.mff.cuni.cz>:
  274.         ("Not on bus" means there is no way for a card to generate this
  275.         interrupt)
  276.         IRQ  0 - Timer 0 (Not on bus)
  277.         IRQ  1 - Keyboard (Not on bus)
  278.         IRQ  2 - IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
  279.         IRQ  3 - COM2
  280.         IRQ  4 - COM1
  281.         IRQ  5 - FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
  282.         IRQ  6 - Floppy disk controller
  283.         IRQ  7 - FREE (LPT1 if you don't use the polling driver; PLIP)
  284.         IRQ  8 - Realtime Clock Interrupt (Not on bus)
  285.         IRQ  9 - FREE (VGA vertical sync interrupt if enabled)
  286.         IRQ 10 - FREE
  287.         IRQ 11 - FREE
  288.         IRQ 12 - FREE
  289.         IRQ 13 - Numeric Coprocessor (Not on bus)
  290.         IRQ 14 - Fixed Disk Controller
  291.         IRQ 15 - FREE (Fixed Disk Controller 2 if you have it)
  292.        
  293.         Note: IRQ 9 is used on some video cards for the "vertical retrace"
  294.         interrupt.  This interrupt would have been handy for things like
  295.         video games, as it occurs exactly once per screen refresh, but
  296.         unfortunately IBM cancelled this feature starting with the original
  297.         VGA and thus many VGA/SVGA cards do not support it.  For this
  298.         reason, no modern software uses this interrupt and it can almost
  299.         always be safely disabled, if your video card supports it at all.
  300.        
  301.         If your card for some reason CANNOT disable this IRQ (usually there
  302.         is a jumper), one solution would be to clip the printed circuit
  303.         contact on the board: it's the fourth contact from the left on the
  304.         back side.  I take no responsibility if you try this.
  305.  
  306.         - Avery's favourite: IRQ2 (actually IRQ9).  Watch that VGA, though.
  307.  
  308.   - the memory address:  Unlike most cards, ARCnets use "shared memory" for
  309.     copying buffers around.  Make SURE it doesn't conflict with any other
  310.     used memory in your system!
  311.         A0000           - VGA graphics memory (ok if you don't have VGA)
  312.         B0000           - Monochrome text mode
  313.         C0000           \  One of these is your VGA BIOS - usually C0000.
  314.         E0000           /
  315.         F0000           - System BIOS
  316.  
  317.     Anything less than 0xA0000 is, well, a BAD idea since it isn't above
  318.     640k.
  319.         - Avery's favourite: 0xD0000
  320.  
  321.   - the station address:  Every ARCnet card has its own "unique" network
  322.     address from 0 to 255.  Unlike Ethernet, you can set this address
  323.     yourself with a jumper or switch (or on some cards, with special
  324.     software).  Since it's only 8 bits, you can only have 254 ARCnet cards
  325.     on a network.  DON'T use 0 or 255, since these are reserved (although
  326.     neat stuff will probably happen if you DO use them).  By the way, if you
  327.     haven't already guessed, don't set this the same as any other ARCnet on
  328.     your network!
  329.         - Avery's favourite:  3 and 4.  Not that it matters.
  330.  
  331.   - There may be ETS1 and ETS2 settings.  These may or may not make a
  332.     difference on your card (many manuals call them "reserved"), but are
  333.     used to change the delays used when powering up a computer on the
  334.     network.  This is only necessary when wiring VERY long range ARCnet
  335.     networks, on the order of 4km or so; in any case, the only real
  336.     requirement here is that all cards on the network with ETS1 and ETS2
  337.     jumpers have them in the same position.  Chris Hindy <chrish@io.org>
  338.     sent in a chart with actual values for this:
  339.         ET1     ET2     Response Time   Reconfiguration Time
  340.         ---     ---     -------------   --------------------
  341.         open    open    74.7us          840us
  342.         open    closed  283.4us         1680us
  343.         closed  open    561.8us         1680us
  344.         closed  closed  1118.6us        1680us
  345.    
  346.     Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
  347.     network.
  348.    
  349. Also, on many cards (not mine, though) there are red and green LED's.
  350. Vojtech Pavlik <Vojtech.Pavlik@st.mff.cuni.cz> tells me this is what they
  351. mean:
  352.         GREEN           RED             Status
  353.         -----           ---             ------
  354.         OFF             OFF             Power off
  355.         OFF             Short flashes   Cabling problems (broken cable or not
  356.                                           terminated)
  357.         OFF (short)     ON              Card init
  358.         ON              ON              Normal state - everything OK, nothing
  359.                                           happens
  360.         ON              Long flashes    Data transfer
  361.         ON              OFF             Never happens (maybe when wrong ID)
  362.  
  363.  
  364. The following is all the specific information people have sent me about
  365. their own particular ARCnet cards.  It is officially a mess, and contains
  366. huge amounts of duplicated information.  I have no time to fix it.  If you
  367. want to, PLEASE DO!  Just send me a 'diff -u' of all your changes.
  368.  
  369. The model # is listed right above specifics for that card, so you should be
  370. able to use your text viewer's "search" function to find the entry you want.
  371. If you don't KNOW what kind of card you have, try looking through the
  372. various diagrams to see if you can tell.

  374. If your model isn't listed and/or has different settings, PLEASE PLEASE
  375. tell me.  I had to figure mine out without the manual, and it WASN'T FUN!

  426.      About the jumpers: On my PC130 there is one more jumper, located near the
  427.      cable-connector and it's for changing to star or bus topology;
  428.      closed: star - open: bus
  429.      On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI
  430.      and another with ALE,LA17,LA18,LA19 these are undocumented..

  442.     from Avery's setup.
  443.   - special thanks to Timo Hilbrink <timoh@xs4all.nl> for noting that PC120,
  444.     130, 500, and 600 all have the same switches as Avery's PC100.
  445.     PC500/600 have several extra, undocumented pins though. (?)
  446.   - PC110 settings were verified by Stephen A. Wood <saw@cebaf.gov>
  447.   - Also, the JP- and S-numbers probably don't match your card exactly.  Try
  448.     to find jumpers/switches with the same number of settings - it's
  449.     probably more reliable.

  609.  
  610. Setting the Node ID
  611. -------------------
  612.  
  613. The eight switches in group S2 are used to set the node ID.
  614. These switches work in a way similar to the PC100-series cards; see that
  615. entry for more information.
  616.  
  617.  
  618. Setting the I/O Base Address
  619. ----------------------------
  620.  
  621. The first three switches in switch group S1 are used to select one
  622. of eight possible I/O Base addresses using the following table
  623.  
  624.  
  625.    Switch | Hex I/O
  626.    1 2 3  | Address

  637.  
  638. Setting the Base Memory (RAM) buffer Address
  639. --------------------------------------------
  640.  
  641. The memory buffer requires 2K of a 16K block of RAM. The base of this
  642. 16K block can be located in any of eight positions.
  643. Switches 4-6 of switch group S1 select the Base of the 16K block.
  644. Within that 16K address space, the buffer may be assigned any one of four
  645. positions, determined by the offset, switches 7 and 8 of group S1.

  692.  
  693.  
  694. Setting the Timeouts and Interrupt
  695. ----------------------------------
  696.  
  697. The jumpers labeled EXT1 and EXT2 are used to determine the timeout
  698. parameters. These two jumpers are normally left open.
  699.  
  700. To select a hardware interrupt level set one (only one!) of the jumpers
  701. IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.

  704. Configuring the PC130E for Star or Bus Topology
  705. -----------------------------------------------
  706.  
  707. The single jumper labeled STAR is used to configure the PC130E board for
  708. star or bus topology.
  709. When the jumper is installed, the board may be used in a star network, when
  710. it is removed, the board can be used in a bus topology.
  711.  
  712.  
  713. Diagnostic LEDs
  714. ---------------
  715.  
  716. Two diagnostic LEDs are visible on the rear bracket of the board.
  717. The green LED monitors the network activity: the red one shows the
  718. board activity:
  719.  
  720.  Green  | Status               Red      | Status
  721.  -------|-------------------   ---------|-------------------
  722.   on    | normal activity      flash/on | data transfer

  737. =====================================================================
  738.  
  739. Note: There is another Version of the PC500 called Short Version, which
  740.       is different in hard- and software! The most important differences
  741.       are:
  742.       - The long board has no Shared memory.
  743.       - On the long board the selection of the interrupt is done by binary
  744.         coded switch, on the short board directly by jumper.
  745.        
  746. [Avery's note: pay special attention to that: the long board HAS NO SHARED
  747. MEMORY.  This means the current Linux-ARCnet driver can't use these cards.
  748. I have obtained a PC500Longboard and will be doing some experiments on it in
  749. the future, but don't hold your breath.  Thanks again to Juergen Seifert for
  750. his advice about this!]

  815. Setting one of the switches to Off/Open means "1", On/Closed means "0".
  816.  
  817.  
  818. Setting the Node ID
  819. -------------------
  820.  
  821. The eight switches in group SW3 are used to set the node ID. Each node
  822. attached to the network must have an unique node ID which must be
  823. different from 0.
  824. Switch 1 serves as the least significant bit (LSB).
  825.  
  826. The node ID is the sum of the values of all switches set to "1"  
  827. These values are:
  828.  
  829.     Switch | Value
  830.     -------|-------
  831.       1    |   1
  832.       2    |   2
  833.       3    |   4
  834.       4    |   8
  835.       5    |  16
  836.       6    |  32
  837.       7    |  64
  838.       8    | 128
  839.  
  840. Some Examples:
  841.  
  842.     Switch         | Hex     | Decimal
  843.    8 7 6 5 4 3 2 1 | Node ID | Node ID
  844.    ----------------|---------|---------

  857.  
  858.  
  859. Setting the I/O Base Address
  860. ----------------------------
  861.  
  862. The first six switches in switch group SW1 are used to select one
  863. of 32 possible I/O Base addresses using the following table
  864.  
  865.    Switch       | Hex I/O
  866.    6 5  4 3 2 1 | Address
  867.    -------------|--------
  868.    0 1  0 0 0 0 |  200
  869.    0 1  0 0 0 1 |  210
  870.    0 1  0 0 1 0 |  220
  871.    0 1  0 0 1 1 |  230
  872.    0 1  0 1 0 0 |  240
  873.    0 1  0 1 0 1 |  250
  874.    0 1  0 1 1 0 |  260
  875.    0 1  0 1 1 1 |  270
  876.    0 1  1 0 0 0 |  280
  877.    0 1  1 0 0 1 |  290
  878.    0 1  1 0 1 0 |  2A0
  879.    0 1  1 0 1 1 |  2B0
  880.    0 1  1 1 0 0 |  2C0
  881.    0 1  1 1 0 1 |  2D0
  882.    0 1  1 1 1 0 |  2E0 (Manufacturer's default)
  883.    0 1  1 1 1 1 |  2F0
  884.    1 1  0 0 0 0 |  300
  885.    1 1  0 0 0 1 |  310
  886.    1 1  0 0 1 0 |  320
  887.    1 1  0 0 1 1 |  330
  888.    1 1  0 1 0 0 |  340
  889.    1 1  0 1 0 1 |  350
  890.    1 1  0 1 1 0 |  360

  896.    1 1  1 1 0 0 |  3C0
  897.    1 1  1 1 0 1 |  3D0
  898.    1 1  1 1 1 0 |  3E0
  899.    1 1  1 1 1 1 |  3F0
  900.  
  901.  
  902. Setting the Interrupt
  903. ---------------------
  904.  
  905. Switches seven through ten of switch group SW1 are used to select the
  906. interrupt level. The interrupt level is binary coded, so selections
  907. from 0 to 15 would be possible, but only the following eight values will
  908. be supported: 3, 4, 5, 7, 9, 10, 11, 12.
  909.  
  910.    Switch   | IRQ
  911.    10 9 8 7 |
  912.    ---------|--------
  913.     0 0 1 1 |  3
  914.     0 1 0 0 |  4
  915.     0 1 0 1 |  5
  916.     0 1 1 1 |  7
  917.     1 0 0 1 |  9 (=2) (default)
  918.     1 0 1 0 | 10
  919.     1 0 1 1 | 11
  920.     1 1 0 0 | 12
  921.  
  922.  
  923. Setting the Timeouts
  924. --------------------
  925.  
  926. The two jumpers JP2 (1-4) are used to determine the timeout parameters.
  927. These two jumpers are normally left open.
  928. Refer to the COM9026 Data Sheet for alternate configurations.
  929.  
  930.  
  931. Configuring the PC500 for Star or Bus Topology
  932. ----------------------------------------------
  933.  
  934. The single jumper labeled JP6 is used to configure the PC500 board for
  935. star or bus topology.
  936. When the jumper is installed, the board may be used in a star network, when
  937. it is removed, the board can be used in a bus topology.
  938.  
  939.  
  940. Diagnostic LEDs
  941. ---------------
  942.  
  943. Two diagnostic LEDs are visible on the rear bracket of the board.
  944. The green LED monitors the network activity: the red one shows the
  945. board activity:
  946.  
  947.  Green  | Status               Red      | Status
  948.  -------|-------------------   ---------|-------------------
  949.   on    | normal activity      flash/on | data transfer
  950.   blink | reconfiguration      off      | no data transfer;
  951.   off   | defective board or            | incorrect memory or
  952.         | node ID is zero               | I/O address
  953.

  958. PC710 (8-bit card)
  959. ------------------
  960.   - from J.S. van Oosten <jvoosten@compiler.tdcnet.nl>
  961.  
  962. Note: this data is gathered by experimenting and looking at info of other
  963. cards. However, I'm sure I got 99% of the settings right.
  964.  
  965. The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
  966. LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing:

  985.            |||||||||||||||||||||
  986.  
  987. The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
  988. labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
  989. IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
  990.  
  991. S1 and S2 perform the same function as on the PC270, only their numbers
  992. are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
  993.  
  994. I know it works when connected to a PC110 type ARCnet board.

  1000. LCS-8830(-T) (8 and 16-bit cards)
  1001. ---------------------------------
  1002.   - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
  1003.   - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
  1004.     LCS-8830 is slightly different from LCS-8830-T.  These are 8 bit, BUS
  1005.     only (the JP0 jumper is hardwired), and BNC only.
  1006.        
  1007. This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
  1008. nowhere else, not even on the few xeroxed sheets from the manual).

  1112. PDI507 (8-bit card)
  1113. --------------------
  1114.   - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
  1115.   - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
  1116.     are mostly the same as this.  PDI508Plus cards appear to be mainly
  1117.     software-configured.
  1118.  
  1119. Jumpers:
  1120.         There is a jumper array at the bottom of the card, near the edge
  1121.         connector.  This array is labelled J1.  They control the IRQs and
  1122.         something else.  Put only one jumper on the IRQ pins.
  1123.  
  1124.         ETS1, ETS2 are for timing on very long distance networks.  See the
  1125.         more general information near the top of this file.
  1126.  
  1127.         There is a J2 jumper on two pins.  A jumper should be put on them,
  1128.         since it was already there when I got the card.  I don't know what
  1129.         this jumper is for though.
  1130.  
  1131.         There is a two-jumper array for J3.  I don't know what it is for,
  1132.         but there were already two jumpers on it when I got the card.  It's
  1133.         a six pin grid in a two-by-three fashion.  The jumpers were
  1134.         configured as follows:
  1135.

  1157.   - If using coax cable in a bus topology the J4 jumper must be removed;
  1158.     place it on one pin.
  1159.  
  1160.   - If using bus topology with twisted pair wiring move the J3
  1161.     jumpers so they connect the middle pin and the pins closest to the RJ11
  1162.     Connectors.  Also the J4 jumper must be removed; place it on one pin of
  1163.     J4 jumper for storage.
  1164.  
  1165.   - If using  star topology with twisted pair wiring move the J3
  1166.     jumpers so they connect the middle pin and the pins closest to the RJ11
  1167.     connectors.
  1168.  
  1169.  
  1170. DIP Switches:
  1171.  
  1172.         The DIP switches accessible on the accessible end of the card while
  1173.         it is installed, is used to set the arcnet address.  There are 8
  1174.         switches.  Use an address from 1 to 254.
  1175.  
  1176.         Switch No.
  1177.         12345678        Arcnet address
  1178.         -----------------------------------------
  1179.         00000000        FF      (Don't use this!)
  1180.         00000001        FE
  1181.         00000010        FD
  1182.         ....
  1183.         11111101        2      
  1184.         11111110        1
  1185.         11111111        0       (Don't use this!)
  1186.  
  1187.         There is another array of eight DIP switches at the top of the
  1188.         card.  There are five labelled MS0-MS4 which seem to control the
  1189.         memory address, and another three labelled IO0-IO2 which seem to
  1190.         control the base I/O address of the card.
  1191.  
  1192.         This was difficult to test by trial and error, and the I/O addresses
  1193.         are in a weird order.  This was tested by setting the DIP switches,
  1194.         rebooting the computer, and attempting to load ARCETHER at various
  1195.         addresses (mostly between 0x200 and 0x400).  The address that caused
  1196.         the red transmit LED to blink, is the one that I thought works.
  1197.  
  1198.         Also, the address 0x3D0 seem to have a special meaning, since the
  1199.         ARCETHER packet driver loaded fine, but without the red LED
  1200.         blinking.  I don't know what 0x3D0 is for though.  I recommend using
  1201.         an address of 0x300 since Windows may not like addresses below
  1202.         0x300.
  1203.  
  1204.         IO Switch No.
  1205.         210             I/O address
  1206.         -------------------------------
  1207.         111             0x260
  1208.         110             0x290
  1209.         101             0x2E0
  1210.         100             0x2F0
  1211.         011             0x300
  1212.         010             0x350
  1213.         001             0x380
  1214.         000             0x3E0
  1215.  
  1216.         The memory switches set a reserved address space of 0x1000 bytes
  1217.         (0x100 segment units, or 4k).  For example if I set an address of
  1218.         0xD000, it will use up addresses 0xD000 to 0xD100.
  1219.  
  1220.         The memory switches were tested by booting using QEMM386 stealth,
  1221.         and using LOADHI to see what address automatically became excluded
  1222.         from the upper memory regions, and then attempting to load ARCETHER
  1223.         using these addresses.
  1224.  
  1225.         I recommend using an arcnet memory address of 0xD000, and putting
  1226.         the EMS page frame at 0xC000 while using QEMM stealth mode.  That
  1227.         way, you get contiguous high memory from 0xD100 almost all the way
  1228.         the end of the megabyte.
  1229.  
  1230.         Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
  1231.         on my card.  It could be malfunctioning on my card.  Experiment with
  1232.         it ON first, and if it doesn't work, set it to OFF.  (It may be a
  1233.         modifier for the 0x200 bit?)
  1234.  
  1235.         MS Switch No.
  1236.         43210           Memory address

  1333.  
  1334.  
  1335. Setting the Node ID
  1336. -------------------
  1337.  
  1338. The eight switches in SW2 are used to set the node ID. Each node attached
  1339. to the network must have an unique node ID which must be different from 0.
  1340. Switch 1 (ID0) serves as the least significant bit (LSB).
  1341.  
  1342. The node ID is the sum of the values of all switches set to "1"  
  1343. These values are:
  1344.  
  1345.    Switch | Label | Value
  1346.    -------|-------|-------
  1347.      1    | ID0   |   1
  1348.      2    | ID1   |   2
  1349.      3    | ID2   |   4
  1350.      4    | ID3   |   8
  1351.      5    | ID4   |  16
  1352.      6    | ID5   |  32
  1353.      7    | ID6   |  64
  1354.      8    | ID7   | 128
  1355.  
  1356. Some Examples:
  1357.  
  1358.     Switch         | Hex     | Decimal
  1359.    8 7 6 5 4 3 2 1 | Node ID | Node ID

  1372.    1 1 1 1 1 1 1 1 |   FF    |  255
  1373.  
  1374.  
  1375. Setting the I/O Base Address
  1376. ----------------------------
  1377.  
  1378. The last three switches in switch block SW1 are used to select one
  1379. of eight possible I/O Base addresses using the following table
  1380.  
  1381.  
  1382.    Switch      | Hex I/O
  1383.     6   7   8  | Address
  1384.    ------------|--------
  1385.    ON  ON  ON  |  260
  1386.    OFF ON  ON  |  290
  1387.    ON  OFF ON  |  2E0  (Manufacturer's default)
  1388.    OFF OFF ON  |  2F0
  1389.    ON  ON  OFF |  300
  1390.    OFF ON  OFF |  350
  1391.    ON  OFF OFF |  380
  1392.    OFF OFF OFF |  3E0
  1393.  
  1394.  
  1395. Setting the Base Memory (RAM) buffer Address
  1396. --------------------------------------------
  1397.  
  1398. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1399. located in any of eight positions. The address of the Boot Prom is
  1400. memory base + 8K or memory base + 0x2000.
  1401. Switches 1-5 of switch block SW1 select the Memory Base address.
  1402.

  1418.       that they can be used to add an offset of 2K, 4K or 6K to the base
  1419.       address, but this feature is not documented in the manual and I
  1420.       haven't tested it yet.

  1542. Setting one of the switches to Off means "1", On means "0".
  1543.  
  1544.  
  1545. Setting the Node ID
  1546. -------------------
  1547.  
  1548. The eight switches in SW2 are used to set the node ID. Each node attached
  1549. to the network must have an unique node ID which must be different from 0.
  1550. Switch 1 (ID0) serves as the least significant bit (LSB).
  1551.  
  1552. The node ID is the sum of the values of all switches set to "1"  
  1553. These values are:
  1554.  
  1555.    Switch | Label | Value
  1556.    -------|-------|-------
  1557.      1    | ID0   |   1
  1558.      2    | ID1   |   2
  1559.      3    | ID2   |   4
  1560.      4    | ID3   |   8
  1561.      5    | ID4   |  16
  1562.      6    | ID5   |  32
  1563.      7    | ID6   |  64
  1564.      8    | ID7   | 128
  1565.  
  1566. Some Examples:
  1567.  
  1568.     Switch         | Hex     | Decimal
  1569.    8 7 6 5 4 3 2 1 | Node ID | Node ID

  1583.  
  1584.  
  1585. Setting the I/O Base Address
  1586. ----------------------------
  1587.  
  1588. The first six switches in switch block SW1 are used to select the I/O Base
  1589. address using the following table:
  1590.  
  1591.              Switch        | Hex I/O
  1592.     1   2   3   4   5   6  | Address
  1593.    ------------------------|--------
  1594.    OFF ON  ON  OFF OFF ON  |  260
  1595.    OFF ON  OFF ON  ON  OFF |  290
  1596.    OFF ON  OFF OFF OFF ON  |  2E0  (Manufacturer's default)
  1597.    OFF ON  OFF OFF OFF OFF |  2F0
  1598.    OFF OFF ON  ON  ON  ON  |  300
  1599.    OFF OFF ON  OFF ON  OFF |  350
  1600.    OFF OFF OFF ON  ON  ON  |  380
  1601.    OFF OFF OFF OFF OFF ON  |  3E0
  1602.  
  1603. Note: Other IO-Base addresses seem to be selectable, but only the above
  1604.       combinations are documented.
  1605.  
  1606.  
  1607. Setting the Base Memory (RAM) buffer Address
  1608. --------------------------------------------
  1609.  
  1610. The switches 7-10 of switch block SW1 are used to select the Memory
  1611. Base address of the RAM (2K) and the PROM.
  1612.  
  1613.    Switch          | Hex RAM | Hex ROM
  1614.     7   8   9  10  | Address | Address
  1615.    ----------------|---------|-----------
  1616.    OFF OFF ON  ON  |  C0000  |  C8000
  1617.    OFF OFF ON  OFF |  D0000  |  D8000 (Default)
  1618.    OFF OFF OFF ON  |  E0000  |  E8000
  1619.  
  1620. Note: Other MEM-Base addresses seem to be selectable, but only the above
  1621.       combinations are documented.
  1622.  
  1623.  
  1624. Setting the Interrupt Line
  1625. --------------------------
  1626.  
  1627. To select a hardware interrupt level install one (only one!) of the jumpers
  1628. JP3 through JP13 using the following table:
  1629.  
  1630.    Jumper | IRQ    
  1631.    -------|-----------------
  1632.      3    |  14
  1633.      4    |  15
  1634.      5    |  12
  1635.      6    |  11
  1636.      7    |  10
  1637.      8    |   3
  1638.      9    |   4
  1639.     10    |   5
  1640.     11    |   6
  1641.     12    |   7
  1642.     13    |   2 (=9) Default!
  1643.  
  1644. Note:  - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
  1645.          Controller
  1646.        - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
  1647.          Hard Disk, it may conflict with their controllers
  1648.  
  1649.  
  1650. Setting the Timeout Parameters
  1651. ------------------------------
  1652.  
  1653. The jumpers labeled JP1 and JP2 are used to determine the timeout
  1654. parameters. These two jumpers are normally left open.
  1655.

  1707. It seems that the bits are considered in reverse order.  Also, you must
  1708. observe that some of those addresses are unusual and I didn't probe them; I
  1709. used a memory dump in DOS to identify them.  For the 00000 configuration and
  1710. some others that I didn't write here the card seems to conflict with the
  1711. video card (an S3 GENDAC). I leave the full decoding of those addresses to
  1712. you.

  1809. Setting the Node ID
  1810. -------------------
  1811.  
  1812. The eight switches in SW2 are used to set the node ID. Each node attached
  1813. to the network must have an unique node ID which must not be 0.
  1814. Switch 1 (ID0) serves as the least significant bit (LSB).
  1815.  
  1816. Setting one of the switches to OFF means "1", ON means "0".
  1817.  
  1818. The node ID is the sum of the values of all switches set to "1"
  1819. These values are:
  1820.  
  1821.    Switch | Value
  1822.    -------|-------
  1823.      1    |   1
  1824.      2    |   2

  1829.      7    |  64
  1830.      8    | 128
  1831.  
  1832. Don't set this to 0 or 255; these values are reserved.
  1833.  
  1834.  
  1835. Setting the I/O Base Address
  1836. ----------------------------
  1837.  
  1838. The switches 1 to 6 of switch block SW1 are used to select one
  1839. of 32 possible I/O Base addresses using the following tables
  1840.    
  1841.           | Hex
  1842.    Switch | Value
  1843.    -------|-------
  1844.      1    | 200  
  1845.      2    | 100  
  1846.      3    |  80  
  1847.      4    |  40  
  1848.      5    |  20  
  1849.      6    |  10
  1850.  
  1851. The I/O address is sum of all switches set to "1". Remember that
  1852. the I/O address space bellow 0x200 is RESERVED for mainboard, so
  1853. switch 1 should be ALWAYS SET TO OFF.
  1854.  
  1855.  
  1856. Setting the Base Memory (RAM) buffer Address
  1857. --------------------------------------------
  1858.  
  1859. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1860. located in any of sixteen positions. However, the addresses below
  1861. A0000 are likely to cause system hang because there's main RAM.
  1862.  
  1863. Jumpers 7-10 of switch block SW1 select the Memory Base address.
  1864.  
  1865.    Switch          | Hex RAM
  1866.     7   8   9  10  | Address
  1867.    ----------------|---------
  1868.    OFF OFF OFF OFF |  F0000 (conflicts with main BIOS)
  1869.    OFF OFF OFF ON  |  E0000
  1870.    OFF OFF ON  OFF |  D0000
  1871.    OFF OFF ON  ON  |  C0000 (conflicts with video BIOS)
  1872.    OFF ON  OFF OFF |  B0000 (conflicts with mono video)
  1873.    OFF ON  OFF ON  |  A0000 (conflicts with graphics)
  1874.  
  1875.  
  1876. Setting the Interrupt Line
  1877. --------------------------
  1878.  
  1879. Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
  1880. shorted, OFF means open.
  1881.  
  1882.     Jumper              |  IRQ
  1883.     1   2   3   4   5   |
  1884.    ----------------------------
  1885.     ON  OFF OFF OFF OFF |  7
  1886.     OFF ON  OFF OFF OFF |  5
  1887.     OFF OFF ON  OFF OFF |  4
  1888.     OFF OFF OFF ON  OFF |  3
  1889.     OFF OFF OFF OFF ON  |  2
  1890.  
  1891.  
  1892. Unknown jumpers & sockets
  1893. -------------------------
  1894.  
  1895. I know nothing about these. I just guess that J16&J17 are timeout
  1896. jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
  1897. J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
  1898. guess the purpose.

  2134. Setting the Base Memory (RAM) buffer Address
  2135. --------------------------------------------
  2136.  
  2137. The memory buffer (RAM) requires 2K. The base of this buffer can be
  2138. located in any of eight positions. The address of the Boot Prom is
  2139. memory base + 0x2000.
  2140. Jumpers 3-5 of switch block SW1 select the Memory Base address.
  2141.  
  2142.    Switch              | Hex RAM | Hex ROM
  2143.     1   2   3   4   5  | Address | Address *)

  2153.  
  2154. *) To enable the Boot ROM short the jumper J2.
  2155.  
  2156. The jumpers 1 and 2 probably add 0x0800 and 0x1000 to RAM address.
  2157.  
  2158.  
  2159. Setting the Interrupt Line
  2160. --------------------------
  2161.  
  2162. Jumpers 1-5 of the jumper block J1 control the IRQ level.  ON means
  2163. shorted, OFF means open.
  2164.  
  2165.     Jumper              |  IRQ
  2166.     1   2   3   4   5   |

  2173.  
  2174.  
  2175. Setting the Timeout Parameters
  2176. ------------------------------
  2177.  
  2178. The jumpers J3 are used to set the timeout parameters. These two
  2179. jumpers are normally left open.

  2251.    . . . . .
  2252.  
  2253.  
  2254. There is a DIP-switch with 8 switches, used to set the shared memory address
  2255. to be used. The first 6 switches set the address, the 7th doesn't have any
  2256. function, and the 8th switch is used to select "compatible" or "enhanced".
  2257. When I got my two cards, one of them had this switch set to "enhanced". That
  2258. card didn't work at all, it wasn't even recognized by the driver. The other
  2259. card had this switch set to "compatible" and it behaved absolutely normally. I
  2260. guess that the switch on one of the cards, must have been changed accidently
  2261. when the card was taken out of its former host. The question remains
  2262. unanswered, what is the purpose of the "enhanced" position?
  2263.  
  2264. [Avery's note: "enhanced" probably either disables shared memory (use IO
  2265. ports instead) or disables IO ports (use memory addresses instead).  This
  2266. varies by the type of card involved.  I fail to see how either of these
  2267. enhance anything.  Send me more detailed information about this mode, or
  2268. just use "compatible" mode instead.]

  2277.  
  2278. [Avery's note: these don't work with my driver for some reason.  These cards
  2279. SEEM to have settings similar to the PDI508Plus, which is
  2280. software-configured and doesn't work with my driver either.  The "Waterloo
  2281. chip" is a boot PROM, probably designed specifically for the University of
  2282. Waterloo.  If you have any further information about this card, please
  2283. e-mail me.]
  2284.  
  2285. The probe has not been able to detect the card on any of the J2 settings,
  2286. and I tried them again with the "Waterloo" chip removed.

  2436. Setting the Node ID
  2437. -------------------
  2438.  
  2439. The eight switches in group SW1 are used to set the node ID.
  2440. Each node attached to the network must have an unique node ID which
  2441. must be different from 0.
  2442. Switch 8 serves as the least significant bit (LSB).
  2443.  
  2444. The node ID is the sum of the values of all switches set to "1"  
  2445. These values are:
  2446.  
  2447.     Switch | Value
  2448.     -------|-------
  2449.       8    |   1

  2477. Setting the I/O Base Address
  2478. ----------------------------
  2479.  
  2480. The first three switches in switch group SW2 are used to select one
  2481. of eight possible I/O Base addresses using the following table
  2482.  
  2483.    Switch      | Hex I/O
  2484.     1   2   3  | Address
  2485.    ------------|--------
  2486.    ON  ON  ON  |  260
  2487.    ON  ON  OFF |  290

  2493.    OFF OFF OFF |  3E0
  2494.  
  2495.  
  2496. Setting the Base Memory (RAM) buffer Address
  2497. --------------------------------------------
  2498.  
  2499. The memory buffer requires 2K of a 16K block of RAM. The base of this
  2500. 16K block can be located in any of eight positions.
  2501. Switches 4-6 of switch group SW2 select the Base of the 16K block.
  2502. Within that 16K address space, the buffer may be assigned any one of four
  2503. positions, determined by the offset, switches 7 and 8 of group SW2.

  2548. *) To enable the 8K Boot PROM install the jumper ROM.
  2549.    The default is jumper ROM not installed.
  2550.  
  2551.  
  2552. Setting Interrupt Request Lines (IRQ)
  2553. -------------------------------------
  2554.  
  2555. To select a hardware interrupt level set one (only one!) of the jumpers
  2556. IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
  2557.  
  2558.  
  2559. Setting the Timeouts
  2560. --------------------
  2561.  
  2562. The two jumpers labeled ET1 and ET2 are used to determine the timeout
  2563. parameters (respons and reconfiguration time). Every node in a network
  2564. must be set to the same timeout values.
  2565.  
  2566.    ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
  2567.    --------|--------------------|--------------------------
  2568.    Off Off |        78          |          840   (Default)

  2576. NONAME 16-BIT ARCNET
  2577. ====================
  2578.  
  2579. The manual of my 8-Bit NONAME ARCnet Card contains another description
  2580. of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
  2581. because there are missing two pages in the manual booklet. (The table
  2582. of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
  2583. the booklet there is a different way of counting ... 2-9, 2-10, A-1,
  2584. (empty page), 3-1, ..., 3-18, A-1 (again), A-2)
  2585. Also the picture of the board layout is not as good as the picture of
  2586. 8-Bit card, because there isn't any letter like "SW1" written to the
  2587. picture.
  2588. Should somebody have such a board, please feel free to complete this
  2589. description or to send a mail to me!
  2590.

  2622. Setting one of the switches to Off means "1", On means "0".
  2623.  
  2624.  
  2625. Setting the Node ID
  2626. -------------------
  2627.  
  2628. The eight switches in group SW2 are used to set the node ID.
  2629. Each node attached to the network must have an unique node ID which
  2630. must be different from 0.
  2631. Switch 8 serves as the least significant bit (LSB).
  2632.  
  2633. The node ID is the sum of the values of all switches set to "1"  
  2634. These values are:
  2635.  
  2636.     Switch | Value
  2637.     -------|-------
  2638.       8    |   1
  2639.       7    |   2
  2640.       6    |   4
  2641.       5    |   8
  2642.       4    |  16
  2643.       3    |  32
  2644.       2    |  64
  2645.       1    | 128
  2646.  
  2647. Some Examples:
  2648.  
  2649.     Switch         | Hex     | Decimal
  2650.    1 2 3 4 5 6 7 8 | Node ID | Node ID

  2666. Setting the I/O Base Address
  2667. ----------------------------
  2668.  
  2669. The first three switches in switch group SW1 are used to select one
  2670. of eight possible I/O Base addresses using the following table
  2671.  
  2672.    Switch      | Hex I/O
  2673.     3   2   1  | Address
  2674.    ------------|--------
  2675.    ON  ON  ON  |  260
  2676.    ON  ON  OFF |  290
  2677.    ON  OFF ON  |  2E0  (Manufacturer's default)
  2678.    ON  OFF OFF |  2F0
  2679.    OFF ON  ON  |  300
  2680.    OFF ON  OFF |  350
  2681.    OFF OFF ON  |  380
  2682.    OFF OFF OFF |  3E0
  2683.  
  2684.  
  2685. Setting the Base Memory (RAM) buffer Address
  2686. --------------------------------------------
  2687.  
  2688. The memory buffer requires 2K of a 16K block of RAM. The base of this
  2689. 16K block can be located in any of eight positions.
  2690. Switches 6-8 of switch group SW1 select the Base of the 16K block.
  2691. Within that 16K address space, the buffer may be assigned any one of four
  2692. positions, determined by the offset, switches 4 and 5 of group SW1.
  2693.  
  2694.    Switch     | Hex RAM | Hex ROM

  2798. Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
  2799. switches.
  2800.  
  2801. Setting the jumpers to ON means connecting the upper two pins, off the bottom
  2802. two - or - in case of IRQ setting, connecting none of them at all.
  2803.  
  2804. Setting the Node ID
  2805. -------------------
  2806.  
  2807. The eight switches in SW2 are used to set the node ID. Each node attached
  2808. to the network must have an unique node ID which must not be 0.
  2809. Switch 1 (ID0) serves as the least significant bit (LSB).
  2810.  
  2811. Setting one of the switches to Off means "1", On means "0".
  2812.  
  2813. The node ID is the sum of the values of all switches set to "1"  
  2814. These values are:
  2815.  
  2816.    Switch | Label | Value
  2817.    -------|-------|-------
  2818.      1    | ID0   |   1
  2819.      2    | ID1   |   2
  2820.      3    | ID2   |   4
  2821.      4    | ID3   |   8
  2822.      5    | ID4   |  16
  2823.      6    | ID5   |  32
  2824.      7    | ID6   |  64
  2825.      8    | ID7   | 128
  2826.  
  2827. Some Examples:
  2828.  
  2829.     Switch         | Hex     | Decimal
  2830.    8 7 6 5 4 3 2 1 | Node ID | Node ID

  2845.  
  2846. Setting the I/O Base Address
  2847. ----------------------------
  2848.  
  2849. The last three switches in switch block SW1 are used to select one
  2850. of eight possible I/O Base addresses using the following table
  2851.  
  2852.  
  2853.    Switch      | Hex I/O
  2854.     6   7   8  | Address
  2855.    ------------|--------
  2856.    ON  ON  ON  |  260
  2857.    OFF ON  ON  |  290
  2858.    ON  OFF ON  |  2E0  (Manufacturer's default)
  2859.    OFF OFF ON  |  2F0
  2860.    ON  ON  OFF |  300
  2861.    OFF ON  OFF |  350
  2862.    ON  OFF OFF |  380
  2863.    OFF OFF OFF |  3E0
  2864.  
  2865.  
  2866. Setting the Base Memory (RAM) buffer Address
  2867. --------------------------------------------
  2868.  
  2869. The memory buffer (RAM) requires 2K. The base of this buffer can be
  2870. located in any of eight positions. The address of the Boot Prom is
  2871. memory base + 0x2000.
  2872. Jumpers 3-5 of jumper block SW1 select the Memory Base address.
  2873.  
  2874.    Switch              | Hex RAM | Hex ROM
  2875.     1   2   3   4   5  | Address | Address *)
  2876.    --------------------|---------|-----------
  2877.    ON  ON  ON  ON  ON  |  C0000  |  C2000
  2878.    ON  ON  OFF ON  ON  |  C4000  |  C6000
  2879.    ON  ON  ON  OFF ON  |  CC000  |  CE000
  2880.    ON  ON  OFF OFF ON  |  D0000  |  D2000  (Manufacturer's default)
  2881.    ON  ON  ON  ON  OFF |  D4000  |  D6000
  2882.    ON  ON  OFF ON  OFF |  D8000  |  DA000
  2883.    ON  ON  ON  OFF OFF |  DC000  |  DE000
  2884.    ON  ON  OFF OFF OFF |  E0000  |  E2000
  2885.  
  2886. *) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
  2887.  
  2888. The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
  2889.  
  2890. Setting the Interrupt Line
  2891. --------------------------
  2892.  
  2893. Jumpers 1-5 of the jumper block SW3 control the IRQ level.
  2894.  
  2895.     Jumper              |  IRQ
  2896.     1   2   3   4   5   |
  2897.    ----------------------------
  2898.     ON  OFF OFF OFF OFF |  2
  2899.     OFF ON  OFF OFF OFF |  3
  2900.     OFF OFF ON  OFF OFF |  4
  2901.     OFF OFF OFF ON  OFF |  5
  2902.     OFF OFF OFF OFF ON  |  7
  2903.  
  2904.  
  2905. Setting the Timeout Parameters
  2906. ------------------------------
  2907.  
  2908. The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
  2909. parameters. These two jumpers are normally left in the OFF position.

  2963.  
  2964. SW1: Timeouts, Interrupt and ROM
  2965. ---------------------------------
  2966.  
  2967. To select a hardware interrupt level set one (only one!) of the dip switches
  2968. up (on) SW1...(switches 1-5)
  2969. IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
  2970.  
  2971. The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
  2972. are used to determine the timeout parameters. These two dip switches
  2973. are normally left off (down).
  2974.  
  2975.    To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
  2976.    The default is jumper ROM not installed.
  2977.  
  2978.  
  2979. Setting the I/O Base Address
  2980. ----------------------------
  2981.  
  2982. The last three switches in switch group SW2 are used to select one
  2983. of eight possible I/O Base addresses using the following table
  2984.  
  2985.  
  2986.    Switch | Hex I/O
  2987.    4 5 6  | Address

  2998.  
  2999. Setting the Base Memory Address (RAM & ROM)
  3000. -------------------------------------------
  3001.  
  3002. The memory buffer requires 2K of a 16K block of RAM. The base of this
  3003. 16K block can be located in any of eight positions.
  3004. Switches 1-3 of switch group SW2 select the Base of the 16K block.
  3005. (0 = DOWN, 1 = UP)
  3006. I could, however, only verify two settings...

  3021. Setting the Node ID
  3022. -------------------
  3023.  
  3024. The eight switches in group SW3 are used to set the node ID.
  3025. Each node attached to the network must have an unique node ID which
  3026. must be different from 0.
  3027. Switch 1 serves as the least significant bit (LSB).
  3028. switches in the DOWN position are OFF (0) and in the UP position are ON (1)
  3029.  
  3030. The node ID is the sum of the values of all switches set to "1"  
  3031. These values are:
  3032.     Switch | Value
  3033.     -------|-------
  3034.       1    |   1
