0021 Introduction to ARCnet
0022 ======================
0023
0024 ARCnet is a network type which works in a way similar to popular Ethernet
0025 networks but which is also different in some very important ways.
0026
0027 First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
0028 (slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
0029 there are others as well, but these are less common. The different hardware
0030 types, as far as I'm aware, are not compatible and so you cannot wire a
0031 100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
0032 work with 100 Mbps cards, but I haven't been able to verify this myself,
0033 since I only have the 2.5 Mbps variety. It is probably not going to saturate
0034 your 100 Mbps card. Stop complaining. :)
0035
0036 You also cannot connect an ARCnet card to any kind of Ethernet card and
0037 expect it to work.
0038
0039 There are two "types" of ARCnet - STAR topology and BUS topology. This
0040 refers to how the cards are meant to be wired together. According to most
0041 available documentation, you can only connect STAR cards to STAR cards and
0042 BUS cards to BUS cards. That makes sense, right? Well, it's not quite
0043 true; see below under "Cabling."
0044
0045 Once you get past these little stumbling blocks, ARCnet is actually quite a
0046 well-designed standard. It uses something called "modified token passing"
0047 which makes it completely incompatible with so-called "Token Ring" cards,
0048 but which makes transfers much more reliable than Ethernet does. In fact,
0049 ARCnet will guarantee that a packet arrives safely at the destination, and
0050 even if it can't possibly be delivered properly (ie. because of a cable
0051 break, or because the destination computer does not exist) it will at least
0052 tell the sender about it.
0053
0054 Because of the carefully defined action of the "token", it will always make
0055 a pass around the "ring" within a maximum length of time. This makes it
0056 useful for realtime networks.
0057
0058 In addition, all known ARCnet cards have an (almost) identical programming
0059 interface. This means that with one ARCnet driver you can support any
0060 card, whereas with Ethernet each manufacturer uses what is sometimes a
0061 completely different programming interface, leading to a lot of different,
0062 sometimes very similar, Ethernet drivers. Of course, always using the same
0063 programming interface also means that when high-performance hardware
0064 facilities like PCI bus mastering DMA appear, it's hard to take advantage of
0065 them. Let's not go into that.
0066
0067 One thing that makes ARCnet cards difficult to program for, however, is the
0068 limit on their packet sizes; standard ARCnet can only send packets that are
0069 up to 508 bytes in length. This is smaller than the Internet "bare minimum"
0070 of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
0071 level of encapsulation is defined by RFC1201, which I call "packet
0072 splitting," that allows "virtual packets" to grow as large as 64K each,
0073 although they are generally kept down to the Ethernet-style 1500 bytes.
0074

0076 advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

0082 Cabling ARCnet Networks
0083 =======================
0084
0085 This section was rewritten by
0086
0087 Vojtech Pavlik <vojtech@suse.cz>
0088
0089 using information from several people, including:
0090
0091 - Avery Pennraun <apenwarr@worldvisions.ca>
0092 - Stephen A. Wood <saw@hallc1.cebaf.gov>
0093 - John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
0094 - Joachim Koenig <jojo@repas.de>
0095
0096 and Avery touched it up a bit, at Vojtech's request.
0097
0098 ARCnet (the classic 2.5 Mbps version) can be connected by two different
0099 types of cabling: coax and twisted pair. The other ARCnet-type networks
0100 (100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
0101 cabling (Type1, Fiber, C1, C4, C5).
0102
0103 For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
0104 also work fine, because ARCnet is a very stable network. I personally use 75
0105 Ohm TV antenna cable.
0106
0107 Cards for coax cabling are shipped in two different variants: for BUS and
0108 STAR network topologies. They are mostly the same. The only difference
0109 lies in the hybrid chip installed. BUS cards use high impedance output,
0110 while STAR use low impedance. Low impedance card (STAR) is electrically
0111 equal to a high impedance one with a terminator installed.
0112
0113 Usually, the ARCnet networks are built up from STAR cards and hubs. There
0114 are two types of hubs - active and passive. Passive hubs are small boxes
0115 with four BNC connectors containing four 47 Ohm resistors::
0116
0117 | | wires
0118 R + junction
0119 -R-+-R- R 47 Ohm resistors
0120 R
0121 |
0122
0123 The shielding is connected together. Active hubs are much more complicated;
0124 they are powered and contain electronics to amplify the signal and send it
0125 to other segments of the net. They usually have eight connectors. Active
0126 hubs come in two variants - dumb and smart. The dumb variant just
0127 amplifies, but the smart one decodes to digital and encodes back all packets
0128 coming through. This is much better if you have several hubs in the net,
0129 since many dumb active hubs may worsen the signal quality.
0130
0131 And now to the cabling. What you can connect together:
0132
0133 1. A card to a card. This is the simplest way of creating a 2-computer
0134 network.
0135
0136 2. A card to a passive hub. Remember that all unused connectors on the hub
0137 must be properly terminated with 93 Ohm (or something else if you don't
0138 have the right ones) terminators.
0139
0140 (Avery's note: oops, I didn't know that. Mine (TV cable) works
0141 anyway, though.)
0142
0143 3. A card to an active hub. Here is no need to terminate the unused
0144 connectors except some kind of aesthetic feeling. But, there may not be
0145 more than eleven active hubs between any two computers. That of course
0146 doesn't limit the number of active hubs on the network.
0147
0148 4. An active hub to another.
0149
0150 5. An active hub to passive hub.
0151
0152 Remember that you cannot connect two passive hubs together. The power loss
0153 implied by such a connection is too high for the net to operate reliably.
0154
0155 An example of a typical ARCnet network::
0156
0157 R S - STAR type card
0158 S------H--------A-------S R - Terminator
0159 | | H - Hub
0160 | | A - Active hub
0161 | S----H----S
0162 S |
0163 |
0164 S
0165
0166 The BUS topology is very similar to the one used by Ethernet. The only
0167 difference is in cable and terminators: they should be 93 Ohm. Ethernet
0168 uses 50 Ohm impedance. You use T connectors to put the computers on a single
0169 line of cable, the bus. You have to put terminators at both ends of the
0170 cable. A typical BUS ARCnet network looks like::
0171
0172 RT----T------T------T------T------TR
0173 B B B B B B
0174
0175 B - BUS type card
0176 R - Terminator
0177 T - T connector
0178
0179 But that is not all! The two types can be connected together. According to
0180 the official documentation the only way of connecting them is using an active
0181 hub::
0182
0183 A------T------T------TR
0184 | B B B
0185 S---H---S
0186 |
0187 S
0188
0189 The official docs also state that you can use STAR cards at the ends of
0190 BUS network in place of a BUS card and a terminator::
0191
0192 S------T------T------S
0193 B B
0194
0195 But, according to my own experiments, you can simply hang a BUS type card
0196 anywhere in middle of a cable in a STAR topology network. And more - you
0197 can use the bus card in place of any star card if you use a terminator. Then
0198 you can build very complicated networks fulfilling all your needs! An
0199 example::
0200
0201 S
0202 |
0203 RT------T-------T------H------S
0204 B B B |
0205 | R
0206 S------A------T-------T-------A-------H------TR
0207 | B B | | B
0208 | S BT |
0209 | | | S----A-----S
0210 S------H---A----S | |
0211 | | S------T----H---S |
0212 S S B R S
0213
0214 A basically different cabling scheme is used with Twisted Pair cabling. Each
0215 of the TP cards has two RJ (phone-cord style) connectors. The cards are
0216 then daisy-chained together using a cable connecting every two neighboring
0217 cards. The ends are terminated with RJ 93 Ohm terminators which plug into
0218 the empty connectors of cards on the ends of the chain. An example::
0219
0220 ___________ ___________
0221 _R_|_ _|_|_ _|_R_
0222 | | | | | |
0223 |Card | |Card | |Card |
0224 |_____| |_____| |_____|
0225
0226
0227 There are also hubs for the TP topology. There is nothing difficult
0228 involved in using them; you just connect a TP chain to a hub on any end or
0229 even at both. This way you can create almost any network configuration.
0230 The maximum of 11 hubs between any two computers on the net applies here as
0231 well. An example::
0232
0233 RP-------P--------P--------H-----P------P-----PR
0234 |
0235 RP-----H--------P--------H-----P------PR
0236 | |
0237 PR PR
0238
0239 R - RJ Terminator
0240 P - TP Card
0241 H - TP Hub
0242
0243 Like any network, ARCnet has a limited cable length. These are the maximum
0244 cable lengths between two active ends (an active end being an active hub or
0245 a STAR card).
0246
0247 ========== ======= ===========
0248 RG-62 93 Ohm up to 650 m
0249 RG-59/U 75 Ohm up to 457 m
0250 RG-11/U 75 Ohm up to 533 m
0251 IBM Type 1 150 Ohm up to 200 m
0252 IBM Type 3 100 Ohm up to 100 m
0253 ========== ======= ===========
0254
0255 The maximum length of all cables connected to a passive hub is limited to 65
0256 meters for RG-62 cabling; less for others. You can see that using passive
0257 hubs in a large network is a bad idea. The maximum length of a single "BUS
0258 Trunk" is about 300 meters for RG-62. The maximum distance between the two
0259 most distant points of the net is limited to 3000 meters. The maximum length
0260 of a TP cable between two cards/hubs is 650 meters.
0261
0262
0263 Setting the Jumpers
0264 ===================
0265
0266 All ARCnet cards should have a total of four or five different settings:
0267
0268 - the I/O address: this is the "port" your ARCnet card is on. Probed
0269 values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
0270 your card has additional ones, which is possible, please tell me.) This
0271 should not be the same as any other device on your system. According to
0272 a doc I got from Novell, MS Windows prefers values of 0x300 or more,
0273 eating net connections on my system (at least) otherwise. My guess is
0274 this may be because, if your card is at 0x2E0, probing for a serial port
0275 at 0x2E8 will reset the card and probably mess things up royally.
0276
0277 - Avery's favourite: 0x300.
0278
0279 - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
0280 on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
0281
0282 Make sure this is different from any other card on your system. Note
0283 that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
0284 "cat /proc/interrupts" for a somewhat complete list of which ones are in
0285 use at any given time. Here is a list of common usages from Vojtech
0286 Pavlik <vojtech@suse.cz>:
0287
0288 ("Not on bus" means there is no way for a card to generate this
0289 interrupt)
0290
0291 ====== =========================================================
0292 IRQ 0 Timer 0 (Not on bus)
0293 IRQ 1 Keyboard (Not on bus)
0294 IRQ 2 IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
0295 IRQ 3 COM2
0296 IRQ 4 COM1
0297 IRQ 5 FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
0298 IRQ 6 Floppy disk controller
0299 IRQ 7 FREE (LPT1 if you don't use the polling driver; PLIP)
0300 IRQ 8 Realtime Clock Interrupt (Not on bus)
0301 IRQ 9 FREE (VGA vertical sync interrupt if enabled)
0302 IRQ 10 FREE
0303 IRQ 11 FREE
0304 IRQ 12 FREE
0305 IRQ 13 Numeric Coprocessor (Not on bus)
0306 IRQ 14 Fixed Disk Controller
0307 IRQ 15 FREE (Fixed Disk Controller 2 if you have it)
0308 ====== =========================================================
0309
0310
0311 .. note::
0312
0313 IRQ 9 is used on some video cards for the "vertical retrace"
0314 interrupt. This interrupt would have been handy for things like
0315 video games, as it occurs exactly once per screen refresh, but
0316 unfortunately IBM cancelled this feature starting with the original
0317 VGA and thus many VGA/SVGA cards do not support it. For this
0318 reason, no modern software uses this interrupt and it can almost
0319 always be safely disabled, if your video card supports it at all.
0320
0321 If your card for some reason CANNOT disable this IRQ (usually there
0322 is a jumper), one solution would be to clip the printed circuit
0323 contact on the board: it's the fourth contact from the left on the
0324 back side. I take no responsibility if you try this.
0325
0326 - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
0327
0328 - the memory address: Unlike most cards, ARCnets use "shared memory" for
0329 copying buffers around. Make SURE it doesn't conflict with any other
0330 used memory in your system!
0331
0332 ::
0333
0334 A0000 - VGA graphics memory (ok if you don't have VGA)
0335 B0000 - Monochrome text mode
0336 C0000 \ One of these is your VGA BIOS - usually C0000.
0337 E0000 /
0338 F0000 - System BIOS
0339
0340 Anything less than 0xA0000 is, well, a BAD idea since it isn't above
0341 640k.
0342
0343 - Avery's favourite: 0xD0000
0344
0345 - the station address: Every ARCnet card has its own "unique" network
0346 address from 0 to 255. Unlike Ethernet, you can set this address
0347 yourself with a jumper or switch (or on some cards, with special
0348 software). Since it's only 8 bits, you can only have 254 ARCnet cards
0349 on a network. DON'T use 0 or 255, since these are reserved (although
0350 neat stuff will probably happen if you DO use them). By the way, if you
0351 haven't already guessed, don't set this the same as any other ARCnet on
0352 your network!
0353
0354 - Avery's favourite: 3 and 4. Not that it matters.
0355
0356 - There may be ETS1 and ETS2 settings. These may or may not make a
0357 difference on your card (many manuals call them "reserved"), but are
0358 used to change the delays used when powering up a computer on the
0359 network. This is only necessary when wiring VERY long range ARCnet
0360 networks, on the order of 4km or so; in any case, the only real
0361 requirement here is that all cards on the network with ETS1 and ETS2
0362 jumpers have them in the same position. Chris Hindy <chrish@io.org>
0363 sent in a chart with actual values for this:
0364
0365 ======= ======= =============== ====================
0366 ET1 ET2 Response Time Reconfiguration Time
0367 ======= ======= =============== ====================

0371 closed closed 1118.6us 1680us
0372 ======= ======= =============== ====================
0373
0374 Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
0375 network.
0376
0377 Also, on many cards (not mine, though) there are red and green LED's.
0378 Vojtech Pavlik <vojtech@suse.cz> tells me this is what they mean:

0388 happens
0389 ON Long flashes Data transfer
0390 ON OFF Never happens (maybe when wrong ID)
0391 =============== =============== =====================================
0392
0393
0394 The following is all the specific information people have sent me about
0395 their own particular ARCnet cards. It is officially a mess, and contains
0396 huge amounts of duplicated information. I have no time to fix it. If you
0397 want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
0398
0399 The model # is listed right above specifics for that card, so you should be
0400 able to use your text viewer's "search" function to find the entry you want.
0401 If you don't KNOW what kind of card you have, try looking through the
0402 various diagrams to see if you can tell.
0403
0404 If your model isn't listed and/or has different settings, PLEASE PLEASE
0405 tell me. I had to figure mine out without the manual, and it WASN'T FUN!
0406
0407 Even if your ARCnet model isn't listed, but has the same jumpers as another
0408 model that is, please e-mail me to say so.

0479 PC500/600 have several extra, undocumented pins though. (?)
0480 - PC110 settings were verified by Stephen A. Wood <saw@cebaf.gov>
0481 - Also, the JP- and S-numbers probably don't match your card exactly. Try
0482 to find jumpers/switches with the same number of settings - it's

0636
0637 Setting the Node ID
0638 ^^^^^^^^^^^^^^^^^^^
0639
0640 The eight switches in group S2 are used to set the node ID.
0641 These switches work in a way similar to the PC100-series cards; see that
0642 entry for more information.
0643
0644
0645 Setting the I/O Base Address
0646 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
0647
0648 The first three switches in switch group S1 are used to select one
0649 of eight possible I/O Base addresses using the following table::
0650
0651
0652 Switch | Hex I/O
0653 1 2 3 | Address
0654 -------|--------
0655 0 0 0 | 260

0661 1 1 0 | 380
0662 1 1 1 | 3E0
0663
0664
0665 Setting the Base Memory (RAM) buffer Address
0666 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
0667
0668 The memory buffer requires 2K of a 16K block of RAM. The base of this
0669 16K block can be located in any of eight positions.
0670 Switches 4-6 of switch group S1 select the Base of the 16K block.
0671 Within that 16K address space, the buffer may be assigned any one of four
0672 positions, determined by the offset, switches 7 and 8 of group S1.

0719 *) To enable the 8K Boot PROM install the jumper ROM.
0720 The default is jumper ROM not installed.
0721
0722
0723 Setting the Timeouts and Interrupt
0724 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
0725
0726 The jumpers labeled EXT1 and EXT2 are used to determine the timeout
0727 parameters. These two jumpers are normally left open.
0728
0729 To select a hardware interrupt level set one (only one!) of the jumpers
0730 IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
0731
0732
0733 Configuring the PC130E for Star or Bus Topology
0734 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
0735
0736 The single jumper labeled STAR is used to configure the PC130E board for
0737 star or bus topology.
0738 When the jumper is installed, the board may be used in a star network, when
0739 it is removed, the board can be used in a bus topology.
0740
0741
0742 Diagnostic LEDs
0743 ^^^^^^^^^^^^^^^
0744
0745 Two diagnostic LEDs are visible on the rear bracket of the board.
0746 The green LED monitors the network activity: the red one shows the
0747 board activity::
0748
0749 Green | Status Red | Status
0750 -------|------------------- ---------|-------------------
0751 on | normal activity flash/on | data transfer
0752 blink | reconfiguration off | no data transfer;
0753 off | defective board or | incorrect memory or
0754 | node ID is zero | I/O address

0757 PC500/PC550 Longboard (16-bit cards)
0758 ------------------------------------
0759
0760 - from Juergen Seifert <seifert@htwm.de>
0761
0762
0763 .. note::
0764
0765 There is another Version of the PC500 called Short Version, which
0766 is different in hard- and software! The most important differences
0767 are:
0768
0769 - The long board has no Shared memory.
0770 - On the long board the selection of the interrupt is done by binary
0771 coded switch, on the short board directly by jumper.
0772
0773 [Avery's note: pay special attention to that: the long board HAS NO SHARED
0774 MEMORY. This means the current Linux-ARCnet driver can't use these cards.
0775 I have obtained a PC500Longboard and will be doing some experiments on it in
0776 the future, but don't hold your breath. Thanks again to Juergen Seifert for
0777 his advice about this!]

0845 Setting the Node ID
0846 ^^^^^^^^^^^^^^^^^^^
0847
0848 The eight switches in group SW3 are used to set the node ID. Each node
0849 attached to the network must have an unique node ID which must be
0850 different from 0.
0851 Switch 1 serves as the least significant bit (LSB).
0852
0853 The node ID is the sum of the values of all switches set to "1"
0854 These values are::
0855
0856 Switch | Value
0857 -------|-------
0858 1 | 1
0859 2 | 2
0860 3 | 4

0886 Setting the I/O Base Address
0887 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
0888
0889 The first six switches in switch group SW1 are used to select one
0890 of 32 possible I/O Base addresses using the following table::
0891
0892 Switch | Hex I/O
0893 6 5 4 3 2 1 | Address

0929 Setting the Interrupt
0930 ^^^^^^^^^^^^^^^^^^^^^
0931
0932 Switches seven through ten of switch group SW1 are used to select the
0933 interrupt level. The interrupt level is binary coded, so selections
0934 from 0 to 15 would be possible, but only the following eight values will
0935 be supported: 3, 4, 5, 7, 9, 10, 11, 12.
0936

0951
0952 Setting the Timeouts
0953 ^^^^^^^^^^^^^^^^^^^^
0954
0955 The two jumpers JP2 (1-4) are used to determine the timeout parameters.
0956 These two jumpers are normally left open.
0957 Refer to the COM9026 Data Sheet for alternate configurations.
0958
0959
0960 Configuring the PC500 for Star or Bus Topology
0961 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
0962
0963 The single jumper labeled JP6 is used to configure the PC500 board for
0964 star or bus topology.
0965 When the jumper is installed, the board may be used in a star network, when
0966 it is removed, the board can be used in a bus topology.

0992 The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
0993 LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing::

1014 The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
1015 labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
1016 IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
1017
1018 S1 and S2 perform the same function as on the PC270, only their numbers
1019 are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
1020
1021 I know it works when connected to a PC110 type ARCnet board.

1029 LCS-8830(-T) (8 and 16-bit cards)
1030 ---------------------------------
1031
1032 - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
1033 - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
1034 LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
1035 only (the JP0 jumper is hardwired), and BNC only.
1036
1037 This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
1038 nowhere else, not even on the few Xeroxed sheets from the manual).

1148 PDI507 (8-bit card)
1149 --------------------
1150
1151 - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
1152 - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
1153 are mostly the same as this. PDI508Plus cards appear to be mainly
1154 software-configured.
1155
1156 Jumpers:
1157
1158 There is a jumper array at the bottom of the card, near the edge
1159 connector. This array is labelled J1. They control the IRQs and
1160 something else. Put only one jumper on the IRQ pins.
1161
1162 ETS1, ETS2 are for timing on very long distance networks. See the
1163 more general information near the top of this file.
1164
1165 There is a J2 jumper on two pins. A jumper should be put on them,
1166 since it was already there when I got the card. I don't know what
1167 this jumper is for though.
1168
1169 There is a two-jumper array for J3. I don't know what it is for,
1170 but there were already two jumpers on it when I got the card. It's
1171 a six pin grid in a two-by-three fashion. The jumpers were
1172 configured as follows::

1194
1195 - If using coax cable in a bus topology the J4 jumper must be removed;
1196 place it on one pin.
1197
1198 - If using bus topology with twisted pair wiring move the J3
1199 jumpers so they connect the middle pin and the pins closest to the RJ11
1200 Connectors. Also the J4 jumper must be removed; place it on one pin of
1201 J4 jumper for storage.
1202
1203 - If using star topology with twisted pair wiring move the J3
1204 jumpers so they connect the middle pin and the pins closest to the RJ11
1205 connectors.
1206
1207
1208 DIP Switches:
1209
1210 The DIP switches accessible on the accessible end of the card while
1211 it is installed, is used to set the ARCnet address. There are 8
1212 switches. Use an address from 1 to 254
1213
1214 ========== =========================
1215 Switch No. ARCnet address
1216 12345678
1217 ========== =========================
1218 00000000 FF (Don't use this!)
1219 00000001 FE
1220 00000010 FD
1221 ...
1222 11111101 2
1223 11111110 1
1224 11111111 0 (Don't use this!)
1225 ========== =========================
1226
1227 There is another array of eight DIP switches at the top of the
1228 card. There are five labelled MS0-MS4 which seem to control the
1229 memory address, and another three labelled IO0-IO2 which seem to
1230 control the base I/O address of the card.
1231
1232 This was difficult to test by trial and error, and the I/O addresses
1233 are in a weird order. This was tested by setting the DIP switches,
1234 rebooting the computer, and attempting to load ARCETHER at various
1235 addresses (mostly between 0x200 and 0x400). The address that caused
1236 the red transmit LED to blink, is the one that I thought works.
1237
1238 Also, the address 0x3D0 seem to have a special meaning, since the
1239 ARCETHER packet driver loaded fine, but without the red LED
1240 blinking. I don't know what 0x3D0 is for though. I recommend using
1241 an address of 0x300 since Windows may not like addresses below
1242 0x300.
1243
1244 ============= ===========
1245 IO Switch No. I/O address
1246 210
1247 ============= ===========

1250 101 0x2E0
1251 100 0x2F0
1252 011 0x300
1253 010 0x350
1254 001 0x380
1255 000 0x3E0
1256 ============= ===========
1257
1258 The memory switches set a reserved address space of 0x1000 bytes
1259 (0x100 segment units, or 4k). For example if I set an address of
1260 0xD000, it will use up addresses 0xD000 to 0xD100.
1261
1262 The memory switches were tested by booting using QEMM386 stealth,
1263 and using LOADHI to see what address automatically became excluded
1264 from the upper memory regions, and then attempting to load ARCETHER
1265 using these addresses.
1266
1267 I recommend using an ARCnet memory address of 0xD000, and putting
1268 the EMS page frame at 0xC000 while using QEMM stealth mode. That
1269 way, you get contiguous high memory from 0xD100 almost all the way
1270 the end of the megabyte.
1271
1272 Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
1273 on my card. It could be malfunctioning on my card. Experiment with
1274 it ON first, and if it doesn't work, set it to OFF. (It may be a
1275 modifier for the 0x200 bit?)

1372
1373
1374 Setting the Node ID
1375 ^^^^^^^^^^^^^^^^^^^
1376
1377 The eight switches in SW2 are used to set the node ID. Each node attached
1378 to the network must have an unique node ID which must be different from 0.
1379 Switch 1 (ID0) serves as the least significant bit (LSB).
1380
1381 The node ID is the sum of the values of all switches set to "1"
1382 These values are:
1383
1384 ======= ====== =====
1385 Switch Label Value
1386 ======= ====== =====
1387 1 ID0 1

1414
1415
1416 Setting the I/O Base Address
1417 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1418
1419 The last three switches in switch block SW1 are used to select one
1420 of eight possible I/O Base addresses using the following table::
1421
1422
1423 Switch | Hex I/O
1424 6 7 8 | Address
1425 ------------|--------
1426 ON ON ON | 260
1427 OFF ON ON | 290
1428 ON OFF ON | 2E0 (Manufacturer's default)
1429 OFF OFF ON | 2F0
1430 ON ON OFF | 300
1431 OFF ON OFF | 350
1432 ON OFF OFF | 380
1433 OFF OFF OFF | 3E0
1434
1435
1436 Setting the Base Memory (RAM) buffer Address
1437 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1438
1439 The memory buffer (RAM) requires 2K. The base of this buffer can be
1440 located in any of eight positions. The address of the Boot Prom is
1441 memory base + 8K or memory base + 0x2000.
1442 Switches 1-5 of switch block SW1 select the Memory Base address.
1443
1444 ::
1445
1446 Switch | Hex RAM | Hex ROM
1447 1 2 3 4 5 | Address | Address *)
1448 --------------------|---------|-----------
1449 ON ON ON ON ON | C0000 | C2000
1450 ON ON OFF ON ON | C4000 | C6000
1451 ON ON ON OFF ON | CC000 | CE000
1452 ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
1453 ON ON ON ON OFF | D4000 | D6000
1454 ON ON OFF ON OFF | D8000 | DA000
1455 ON ON ON OFF OFF | DC000 | DE000
1456 ON ON OFF OFF OFF | E0000 | E2000
1457
1458 *) To enable the Boot ROM install the jumper JP1
1459
1460 .. note::
1461
1462 Since the switches 1 and 2 are always set to ON it may be possible
1463 that they can be used to add an offset of 2K, 4K or 6K to the base
1464 address, but this feature is not documented in the manual and I
1465 haven't tested it yet.
1466
1467
1468 Setting the Interrupt Line
1469 ^^^^^^^^^^^^^^^^^^^^^^^^^^
1470
1471 To select a hardware interrupt level install one (only one!) of the jumpers
1472 JP2, JP3, JP4, JP5, JP6. JP2 is the default::
1473
1474 Jumper | IRQ
1475 -------|-----
1476 2 | 2
1477 3 | 3
1478 4 | 4
1479 5 | 5
1480 6 | 7
1481
1482
1483 Setting the Internal Terminator on CN120AB/TP/SBT
1484 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1485
1486 The jumper JP12 is used to enable the internal terminator::
1487
1488 -----
1489 0 | 0 |
1490 ----- ON | | ON

1583
1584
1585 Setting the Node ID
1586 ^^^^^^^^^^^^^^^^^^^
1587
1588 The eight switches in SW2 are used to set the node ID. Each node attached
1589 to the network must have an unique node ID which must be different from 0.
1590 Switch 1 (ID0) serves as the least significant bit (LSB).
1591
1592 The node ID is the sum of the values of all switches set to "1"
1593 These values are::
1594
1595 Switch | Label | Value
1596 -------|-------|-------
1597 1 | ID0 | 1
1598 2 | ID1 | 2
1599 3 | ID2 | 4
1600 4 | ID3 | 8
1601 5 | ID4 | 16
1602 6 | ID5 | 32
1603 7 | ID6 | 64
1604 8 | ID7 | 128
1605
1606 Some Examples::
1607
1608 Switch | Hex | Decimal
1609 8 7 6 5 4 3 2 1 | Node ID | Node ID
1610 ----------------|---------|---------

1623
1624
1625 Setting the I/O Base Address
1626 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1627
1628 The first six switches in switch block SW1 are used to select the I/O Base
1629 address using the following table::
1630
1631 Switch | Hex I/O
1632 1 2 3 4 5 6 | Address
1633 ------------------------|--------
1634 OFF ON ON OFF OFF ON | 260
1635 OFF ON OFF ON ON OFF | 290
1636 OFF ON OFF OFF OFF ON | 2E0 (Manufacturer's default)
1637 OFF ON OFF OFF OFF OFF | 2F0
1638 OFF OFF ON ON ON ON | 300
1639 OFF OFF ON OFF ON OFF | 350
1640 OFF OFF OFF ON ON ON | 380
1641 OFF OFF OFF OFF OFF ON | 3E0
1642
1643 Note: Other IO-Base addresses seem to be selectable, but only the above
1644 combinations are documented.
1645
1646
1647 Setting the Base Memory (RAM) buffer Address
1648 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1649
1650 The switches 7-10 of switch block SW1 are used to select the Memory
1651 Base address of the RAM (2K) and the PROM::
1652
1653 Switch | Hex RAM | Hex ROM
1654 7 8 9 10 | Address | Address
1655 ----------------|---------|-----------
1656 OFF OFF ON ON | C0000 | C8000
1657 OFF OFF ON OFF | D0000 | D8000 (Default)
1658 OFF OFF OFF ON | E0000 | E8000
1659
1660 .. note::
1661
1662 Other MEM-Base addresses seem to be selectable, but only the above
1663 combinations are documented.
1664
1665
1666 Setting the Interrupt Line
1667 ^^^^^^^^^^^^^^^^^^^^^^^^^^
1668
1669 To select a hardware interrupt level install one (only one!) of the jumpers
1670 JP3 through JP13 using the following table::
1671
1672 Jumper | IRQ
1673 -------|-----------------
1674 3 | 14
1675 4 | 15
1676 5 | 12
1677 6 | 11
1678 7 | 10
1679 8 | 3
1680 9 | 4
1681 10 | 5
1682 11 | 6
1683 12 | 7
1684 13 | 2 (=9) Default!
1685
1686 .. note::
1687
1688 - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
1689 Controller
1690 - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
1691 Hard Disk, it may conflict with their controllers
1692
1693
1694 Setting the Timeout Parameters
1695 ------------------------------
1696
1697 The jumpers labeled JP1 and JP2 are used to determine the timeout
1698 parameters. These two jumpers are normally left open.

1754
1755 It seems that the bits are considered in reverse order. Also, you must
1756 observe that some of those addresses are unusual and I didn't probe them; I
1757 used a memory dump in DOS to identify them. For the 00000 configuration and
1758 some others that I didn't write here the card seems to conflict with the
1759 video card (an S3 GENDAC). I leave the full decoding of those addresses to
1760 you.

1790 arcnet-hardware file.
1791
1792 This is a 90C26 based card. Its configuration seems similar to the SMC
1793 PC100, but has some additional jumpers I don't know the meaning of.

1862 Setting the Node ID
1863 ^^^^^^^^^^^^^^^^^^^
1864
1865 The eight switches in SW2 are used to set the node ID. Each node attached
1866 to the network must have an unique node ID which must not be 0.
1867 Switch 1 (ID0) serves as the least significant bit (LSB).
1868
1869 Setting one of the switches to OFF means "1", ON means "0".
1870
1871 The node ID is the sum of the values of all switches set to "1"
1872 These values are::
1873
1874 Switch | Value
1875 -------|-------
1876 1 | 1
1877 2 | 2
1878 3 | 4
1879 4 | 8
1880 5 | 16
1881 6 | 32
1882 7 | 64
1883 8 | 128
1884
1885 Don't set this to 0 or 255; these values are reserved.
1886
1887
1888 Setting the I/O Base Address
1889 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1890
1891 The switches 1 to 6 of switch block SW1 are used to select one
1892 of 32 possible I/O Base addresses using the following tables::
1893
1894 | Hex
1895 Switch | Value
1896 -------|-------
1897 1 | 200
1898 2 | 100
1899 3 | 80
1900 4 | 40
1901 5 | 20
1902 6 | 10
1903
1904 The I/O address is sum of all switches set to "1". Remember that
1905 the I/O address space bellow 0x200 is RESERVED for mainboard, so
1906 switch 1 should be ALWAYS SET TO OFF.
1907
1908
1909 Setting the Base Memory (RAM) buffer Address
1910 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1911
1912 The memory buffer (RAM) requires 2K. The base of this buffer can be
1913 located in any of sixteen positions. However, the addresses below
1914 A0000 are likely to cause system hang because there's main RAM.
1915
1916 Jumpers 7-10 of switch block SW1 select the Memory Base address::
1917
1918 Switch | Hex RAM
1919 7 8 9 10 | Address
1920 ----------------|---------
1921 OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
1922 OFF OFF OFF ON | E0000
1923 OFF OFF ON OFF | D0000
1924 OFF OFF ON ON | C0000 (conflicts with video BIOS)
1925 OFF ON OFF OFF | B0000 (conflicts with mono video)
1926 OFF ON OFF ON | A0000 (conflicts with graphics)
1927
1928
1929 Setting the Interrupt Line
1930 ^^^^^^^^^^^^^^^^^^^^^^^^^^
1931
1932 Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
1933 shorted, OFF means open::
1934
1935 Jumper | IRQ
1936 1 2 3 4 5 |
1937 ----------------------------
1938 ON OFF OFF OFF OFF | 7
1939 OFF ON OFF OFF OFF | 5
1940 OFF OFF ON OFF OFF | 4
1941 OFF OFF OFF ON OFF | 3
1942 OFF OFF OFF OFF ON | 2
1943
1944
1945 Unknown jumpers & sockets
1946 ^^^^^^^^^^^^^^^^^^^^^^^^^
1947
1948 I know nothing about these. I just guess that J16&J17 are timeout
1949 jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
1950 J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
1951 guess the purpose.
1952

1960
1961 This is another SMC 90C65-based ARCnet card. I couldn't identify the
1962 manufacturer, but it might be DataPoint, because the card has the
1963 original arcNet logo in its upper right corner.

2152 Setting the Node ID
2153 ^^^^^^^^^^^^^^^^^^^
2154
2155 The eight switches in SW2 are used to set the node ID. Each node attached to
2156 the network must have an unique node ID which must not be 0. Switch 1 (ID0)
2157 serves as the least significant bit (LSB).
2158
2159 Setting one of the switches to Off means "1", On means "0".
2160
2161 The node ID is the sum of the values of all switches set to "1"
2162 These values are::
2163
2164 Switch | Label | Value
2165 -------|-------|-------
2166 1 | ID0 | 1
2167 2 | ID1 | 2

2173 8 | ID7 | 128
2174
2175 Setting the I/O Base Address
2176 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2177
2178 The last three switches in switch block SW1 are used to select one
2179 of eight possible I/O Base addresses using the following table::
2180
2181
2182 Switch | Hex I/O
2183 6 7 8 | Address
2184 ------------|--------
2185 ON ON ON | 260 (Manufacturer's default)

2191 ON OFF OFF | 380
2192 OFF OFF OFF | 3E0
2193
2194
2195 Setting the Base Memory (RAM) buffer Address
2196 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2197
2198 The memory buffer (RAM) requires 2K. The base of this buffer can be
2199 located in any of eight positions. The address of the Boot Prom is
2200 memory base + 0x2000.
2201
2202 Jumpers 3-5 of switch block SW1 select the Memory Base address.

2217
2218 *) To enable the Boot ROM short the jumper J2.
2219
2220 The jumpers 1 and 2 probably add 0x0800 and 0x1000 to RAM address.
2221
2222
2223 Setting the Interrupt Line
2224 ^^^^^^^^^^^^^^^^^^^^^^^^^^
2225
2226 Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
2227 shorted, OFF means open::
2228
2229 Jumper | IRQ

2237
2238
2239 Setting the Timeout Parameters
2240 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2241
2242 The jumpers J3 are used to set the timeout parameters. These two
2243 jumpers are normally left open.

2323 There is a DIP-switch with 8 switches, used to set the shared memory address
2324 to be used. The first 6 switches set the address, the 7th doesn't have any
2325 function, and the 8th switch is used to select "compatible" or "enhanced".
2326 When I got my two cards, one of them had this switch set to "enhanced". That
2327 card didn't work at all, it wasn't even recognized by the driver. The other
2328 card had this switch set to "compatible" and it behaved absolutely normally. I
2329 guess that the switch on one of the cards, must have been changed accidentally
2330 when the card was taken out of its former host. The question remains
2331 unanswered, what is the purpose of the "enhanced" position?
2332
2333 [Avery's note: "enhanced" probably either disables shared memory (use IO
2334 ports instead) or disables IO ports (use memory addresses instead). This
2335 varies by the type of card involved. I fail to see how either of these
2336 enhance anything. Send me more detailed information about this mode, or
2337 just use "compatible" mode instead.]

2345
2346 [Avery's note: these don't work with my driver for some reason. These cards
2347 SEEM to have settings similar to the PDI508Plus, which is
2348 software-configured and doesn't work with my driver either. The "Waterloo
2349 chip" is a boot PROM, probably designed specifically for the University of
2350 Waterloo. If you have any further information about this card, please
2351 e-mail me.]
2352
2353 The probe has not been able to detect the card on any of the J2 settings,
2354 and I tried them again with the "Waterloo" chip removed.

2507 Setting the Node ID
2508 ^^^^^^^^^^^^^^^^^^^
2509
2510 The eight switches in group SW1 are used to set the node ID.
2511 Each node attached to the network must have an unique node ID which
2512 must be different from 0.
2513 Switch 8 serves as the least significant bit (LSB).
2514
2515 The node ID is the sum of the values of all switches set to "1"
2516 These values are::
2517
2518 Switch | Value
2519 -------|-------
2520 8 | 1

2546
2547
2548 Setting the I/O Base Address
2549 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2550
2551 The first three switches in switch group SW2 are used to select one
2552 of eight possible I/O Base addresses using the following table::
2553
2554 Switch | Hex I/O
2555 1 2 3 | Address
2556 ------------|--------
2557 ON ON ON | 260
2558 ON ON OFF | 290
2559 ON OFF ON | 2E0 (Manufacturer's default)
2560 ON OFF OFF | 2F0
2561 OFF ON ON | 300
2562 OFF ON OFF | 350
2563 OFF OFF ON | 380
2564 OFF OFF OFF | 3E0
2565
2566
2567 Setting the Base Memory (RAM) buffer Address
2568 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2569
2570 The memory buffer requires 2K of a 16K block of RAM. The base of this
2571 16K block can be located in any of eight positions.
2572 Switches 4-6 of switch group SW2 select the Base of the 16K block.
2573 Within that 16K address space, the buffer may be assigned any one of four
2574 positions, determined by the offset, switches 7 and 8 of group SW2.

2622 The default is jumper ROM not installed.
2623
2624
2625 Setting Interrupt Request Lines (IRQ)
2626 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2627
2628 To select a hardware interrupt level set one (only one!) of the jumpers
2629 IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2.
2630
2631
2632 Setting the Timeouts
2633 ^^^^^^^^^^^^^^^^^^^^
2634
2635 The two jumpers labeled ET1 and ET2 are used to determine the timeout
2636 parameters (response and reconfiguration time). Every node in a network
2637 must be set to the same timeout values.
2638
2639 ::
2640
2641 ET1 ET2 | Response Time (us) | Reconfiguration Time (ms)
2642 --------|--------------------|--------------------------
2643 Off Off | 78 | 840 (Default)
2644 Off On | 285 | 1680
2645 On Off | 563 | 1680
2646 On On | 1130 | 1680
2647

2651 16-BIT ARCNET
2652 -------------
2653
2654 The manual of my 8-Bit NONAME ARCnet Card contains another description
2655 of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
2656 because there are missing two pages in the manual booklet. (The table
2657 of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
2658 the booklet there is a different way of counting ... 2-9, 2-10, A-1,
2659 (empty page), 3-1, ..., 3-18, A-1 (again), A-2)
2660 Also the picture of the board layout is not as good as the picture of
2661 8-Bit card, because there isn't any letter like "SW1" written to the
2662 picture.
2663
2664 Should somebody have such a board, please feel free to complete this
2665 description or to send a mail to me!

2700 Setting one of the switches to Off means "1", On means "0".
2701
2702
2703 Setting the Node ID
2704 ^^^^^^^^^^^^^^^^^^^
2705
2706 The eight switches in group SW2 are used to set the node ID.
2707 Each node attached to the network must have an unique node ID which
2708 must be different from 0.
2709 Switch 8 serves as the least significant bit (LSB).
2710
2711 The node ID is the sum of the values of all switches set to "1"
2712 These values are::
2713
2714 Switch | Value
2715 -------|-------
2716 8 | 1
2717 7 | 2
2718 6 | 4

2742
2743
2744 Setting the I/O Base Address
2745 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2746
2747 The first three switches in switch group SW1 are used to select one
2748 of eight possible I/O Base addresses using the following table::
2749
2750 Switch | Hex I/O
2751 3 2 1 | Address
2752 ------------|--------

2761
2762
2763 Setting the Base Memory (RAM) buffer Address
2764 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2765
2766 The memory buffer requires 2K of a 16K block of RAM. The base of this
2767 16K block can be located in any of eight positions.
2768 Switches 6-8 of switch group SW1 select the Base of the 16K block.
2769 Within that 16K address space, the buffer may be assigned any one of four
2770 positions, determined by the offset, switches 4 and 5 of group SW1::
2771

2828 8-bit cards ("Made in Taiwan R.O.C.")
2829 -------------------------------------
2830
2831 - from Vojtech Pavlik <vojtech@suse.cz>
2832
2833 I have named this ARCnet card "NONAME", since I got only the card with
2834 no manual at all and the only text identifying the manufacturer is
2835 "MADE IN TAIWAN R.O.C" printed on the card.

2876 Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
2877 switches.
2878
2879 Setting the jumpers to ON means connecting the upper two pins, off the bottom
2880 two - or - in case of IRQ setting, connecting none of them at all.
2881
2882 Setting the Node ID
2883 ^^^^^^^^^^^^^^^^^^^
2884
2885 The eight switches in SW2 are used to set the node ID. Each node attached
2886 to the network must have an unique node ID which must not be 0.
2887 Switch 1 (ID0) serves as the least significant bit (LSB).
2888
2889 Setting one of the switches to Off means "1", On means "0".
2890
2891 The node ID is the sum of the values of all switches set to "1"
2892 These values are::
2893
2894 Switch | Label | Value
2895 -------|-------|-------
2896 1 | ID0 | 1

2923
2924 Setting the I/O Base Address
2925 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2926
2927 The last three switches in switch block SW1 are used to select one
2928 of eight possible I/O Base addresses using the following table::
2929
2930
2931 Switch | Hex I/O
2932 6 7 8 | Address

2943
2944 Setting the Base Memory (RAM) buffer Address
2945 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2946
2947 The memory buffer (RAM) requires 2K. The base of this buffer can be
2948 located in any of eight positions. The address of the Boot Prom is
2949 memory base + 0x2000.
2950
2951 Jumpers 3-5 of jumper block SW1 select the Memory Base address.
2952
2953 ::

2965 ON ON OFF OFF OFF | E0000 | E2000
2966
2967 *) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
2968
2969 The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
2970
2971 Setting the Interrupt Line
2972 ^^^^^^^^^^^^^^^^^^^^^^^^^^
2973
2974 Jumpers 1-5 of the jumper block SW3 control the IRQ level::

3051 up (on) SW1...(switches 1-5)
3052 IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
3053
3054 The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
3055 are used to determine the timeout parameters. These two dip switches
3056 are normally left off (down).

3082 Setting the Base Memory Address (RAM & ROM)
3083 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3084
3085 The memory buffer requires 2K of a 16K block of RAM. The base of this
3086 16K block can be located in any of eight positions.
3087 Switches 1-3 of switch group SW2 select the Base of the 16K block.
3088 (0 = DOWN, 1 = UP)
3089 I could, however, only verify two settings...

3107 Setting the Node ID
3108 ^^^^^^^^^^^^^^^^^^^
3109
3110 The eight switches in group SW3 are used to set the node ID.
3111 Each node attached to the network must have an unique node ID which
3112 must be different from 0.
3113 Switch 1 serves as the least significant bit (LSB).
3114 switches in the DOWN position are OFF (0) and in the UP position are ON (1)
3115
3116 The node ID is the sum of the values of all switches set to "1"
3117 These values are::
3118
3119 Switch | Value
3120 -------|-------
3121 1 | 1
3122 2 | 2
3123 3 | 4
3124 4 | 8
3125 5 | 16
3126 6 | 32
3127 7 | 64
3128 8 | 128
