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@worldvisions.ca with any settings for your particular card, | |

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 bus mastering 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 | ||

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@suse.cz> | |
82 | using information from several people, including: | |
83 | Avery Pennraun <apenwarr@worldvisions.ca> | |
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 | ||
84eb8d06 | 142 | Remember that you cannot connect two passive hubs together. The power loss |
1da177e4 LT |
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@suse.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@suse.cz> tells me this is what they mean: | |
351 | GREEN RED Status | |
352 | ----- --- ------ | |
353 | OFF OFF Power off | |
354 | OFF Short flashes Cabling problems (broken cable or not | |
355 | terminated) | |
356 | OFF (short) ON Card init | |
357 | ON ON Normal state - everything OK, nothing | |
358 | happens | |
359 | ON Long flashes Data transfer | |
360 | ON OFF Never happens (maybe when wrong ID) | |
361 | ||
362 | ||
363 | The following is all the specific information people have sent me about | |
364 | their own particular ARCnet cards. It is officially a mess, and contains | |
365 | huge amounts of duplicated information. I have no time to fix it. If you | |
366 | want to, PLEASE DO! Just send me a 'diff -u' of all your changes. | |
367 | ||
368 | The model # is listed right above specifics for that card, so you should be | |
369 | able to use your text viewer's "search" function to find the entry you want. | |
370 | If you don't KNOW what kind of card you have, try looking through the | |
371 | various diagrams to see if you can tell. | |
372 | ||
373 | If your model isn't listed and/or has different settings, PLEASE PLEASE | |
374 | tell me. I had to figure mine out without the manual, and it WASN'T FUN! | |
375 | ||
376 | Even if your ARCnet model isn't listed, but has the same jumpers as another | |
377 | model that is, please e-mail me to say so. | |

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

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

635 | ||
636 | ||
637 | Setting the Base Memory (RAM) buffer Address | |
638 | -------------------------------------------- | |
639 | ||
640 | The memory buffer requires 2K of a 16K block of RAM. The base of this | |
641 | 16K block can be located in any of eight positions. | |
642 | Switches 4-6 of switch group S1 select the Base of the 16K block. | |
643 | Within that 16K address space, the buffer may be assigned any one of four | |
644 | positions, determined by the offset, switches 7 and 8 of group S1. | |

689 | *) To enable the 8K Boot PROM install the jumper ROM. | |
690 | The default is jumper ROM not installed. | |
691 | ||
692 | ||
693 | Setting the Timeouts and Interrupt | |
694 | ---------------------------------- | |
695 | ||
696 | The jumpers labeled EXT1 and EXT2 are used to determine the timeout | |
697 | parameters. These two jumpers are normally left open. | |
698 | ||
699 | To select a hardware interrupt level set one (only one!) of the jumpers | |
700 | IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2. | |
701 | ||
702 | ||
703 | Configuring the PC130E for Star or Bus Topology | |
704 | ----------------------------------------------- | |
705 | ||
706 | The single jumper labeled STAR is used to configure the PC130E board for | |
707 | star or bus topology. | |
708 | When the jumper is installed, the board may be used in a star network, when | |
709 | it is removed, the board can be used in a bus topology. | |
710 | ||
711 | ||
712 | Diagnostic LEDs | |
713 | --------------- | |
714 | ||
715 | Two diagnostic LEDs are visible on the rear bracket of the board. | |
716 | The green LED monitors the network activity: the red one shows the | |
717 | board activity: | |

736 | ===================================================================== | |
737 | ||
738 | Note: There is another Version of the PC500 called Short Version, which | |
739 | is different in hard- and software! The most important differences | |
740 | are: | |
741 | - The long board has no Shared memory. | |
742 | - On the long board the selection of the interrupt is done by binary | |
743 | coded switch, on the short board directly by jumper. | |
744 | ||
745 | [Avery's note: pay special attention to that: the long board HAS NO SHARED | |
746 | MEMORY. This means the current Linux-ARCnet driver can't use these cards. | |
747 | I have obtained a PC500Longboard and will be doing some experiments on it in | |
748 | the future, but don't hold your breath. Thanks again to Juergen Seifert for | |
749 | his advice about this!] | |

817 | Setting the Node ID | |
818 | ------------------- | |
819 | ||
820 | The eight switches in group SW3 are used to set the node ID. Each node | |
821 | attached to the network must have an unique node ID which must be | |
822 | different from 0. | |
823 | Switch 1 serves as the least significant bit (LSB). | |
824 | ||
825 | The node ID is the sum of the values of all switches set to "1" | |
826 | These values are: | |
827 | ||

901 | Setting the Interrupt | |
902 | --------------------- | |
903 | ||
904 | Switches seven through ten of switch group SW1 are used to select the | |
905 | interrupt level. The interrupt level is binary coded, so selections | |
906 | from 0 to 15 would be possible, but only the following eight values will | |
907 | be supported: 3, 4, 5, 7, 9, 10, 11, 12. | |
908 | ||

920 | ||
921 | ||
922 | Setting the Timeouts | |
923 | -------------------- | |
924 | ||
925 | The two jumpers JP2 (1-4) are used to determine the timeout parameters. | |
926 | These two jumpers are normally left open. | |
927 | Refer to the COM9026 Data Sheet for alternate configurations. | |
928 | ||
929 | ||
930 | Configuring the PC500 for Star or Bus Topology | |
931 | ---------------------------------------------- | |
932 | ||
933 | The single jumper labeled JP6 is used to configure the PC500 board for | |
934 | star or bus topology. | |
935 | When the jumper is installed, the board may be used in a star network, when | |
936 | it is removed, the board can be used in a bus topology. | |
937 | ||
938 | ||
939 | Diagnostic LEDs | |
940 | --------------- | |
941 | ||
942 | Two diagnostic LEDs are visible on the rear bracket of the board. | |
943 | The green LED monitors the network activity: the red one shows the | |
944 | board activity: | |

960 | ||
961 | Note: this data is gathered by experimenting and looking at info of other | |
962 | cards. However, I'm sure I got 99% of the settings right. | |
963 | ||
964 | The SMC710 card resembles the PC270 card, but is much more basic (i.e. no | |
965 | LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing: | |

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

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

1111 | PDI507 (8-bit card) | |
1112 | -------------------- | |
1113 | - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery) | |
1114 | - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards) | |
1115 | are mostly the same as this. PDI508Plus cards appear to be mainly | |
1116 | software-configured. | |
1117 | ||
1118 | Jumpers: | |
1119 | There is a jumper array at the bottom of the card, near the edge | |
1120 | connector. This array is labelled J1. They control the IRQs and | |
1121 | something else. Put only one jumper on the IRQ pins. | |
1122 | ||
1123 | ETS1, ETS2 are for timing on very long distance networks. See the | |
1124 | more general information near the top of this file. | |
1125 | ||
1126 | There is a J2 jumper on two pins. A jumper should be put on them, | |
1127 | since it was already there when I got the card. I don't know what | |
1128 | this jumper is for though. | |
1129 | ||
1130 | There is a two-jumper array for J3. I don't know what it is for, | |
1131 | but there were already two jumpers on it when I got the card. It's | |
1132 | a six pin grid in a two-by-three fashion. The jumpers were | |
1133 | configured as follows: | |
1134 | ||

1155 | ||
1156 | - If using coax cable in a bus topology the J4 jumper must be removed; | |
1157 | place it on one pin. | |
1158 | ||
1159 | - If using bus topology with twisted pair wiring move the J3 | |
1160 | jumpers so they connect the middle pin and the pins closest to the RJ11 | |
1161 | Connectors. Also the J4 jumper must be removed; place it on one pin of | |
1162 | J4 jumper for storage. | |
1163 | ||
1164 | - If using star topology with twisted pair wiring move the J3 | |
1165 | jumpers so they connect the middle pin and the pins closest to the RJ11 | |
1166 | connectors. | |
1167 | ||
1168 | ||
1169 | DIP Switches: | |
1170 | ||
1171 | The DIP switches accessible on the accessible end of the card while | |
1172 | it is installed, is used to set the ARCnet address. There are 8 | |
1173 | switches. Use an address from 1 to 254. | |
1174 | ||
1175 | Switch No. | |
1176 | 12345678 ARCnet address | |
1177 | ----------------------------------------- | |
1178 | 00000000 FF (Don't use this!) | |
1179 | 00000001 FE | |
1180 | 00000010 FD | |
1181 | .... | |
1182 | 11111101 2 | |
1183 | 11111110 1 | |
1184 | 11111111 0 (Don't use this!) | |
1185 | ||
1186 | There is another array of eight DIP switches at the top of the | |
1187 | card. There are five labelled MS0-MS4 which seem to control the | |
1188 | memory address, and another three labelled IO0-IO2 which seem to | |
1189 | control the base I/O address of the card. | |
1190 | ||
1191 | This was difficult to test by trial and error, and the I/O addresses | |
1192 | are in a weird order. This was tested by setting the DIP switches, | |
1193 | rebooting the computer, and attempting to load ARCETHER at various | |
1194 | addresses (mostly between 0x200 and 0x400). The address that caused | |
1195 | the red transmit LED to blink, is the one that I thought works. | |
1196 | ||
1197 | Also, the address 0x3D0 seem to have a special meaning, since the | |
1198 | ARCETHER packet driver loaded fine, but without the red LED | |
1199 | blinking. I don't know what 0x3D0 is for though. I recommend using | |
1200 | an address of 0x300 since Windows may not like addresses below | |
1201 | 0x300. | |
1202 | ||
1203 | IO Switch No. | |
1204 | 210 I/O address | |
1205 | ------------------------------- | |
1206 | 111 0x260 | |
1207 | 110 0x290 | |
1208 | 101 0x2E0 | |
1209 | 100 0x2F0 | |
1210 | 011 0x300 | |
1211 | 010 0x350 | |
1212 | 001 0x380 | |
1213 | 000 0x3E0 | |
1214 | ||
1215 | The memory switches set a reserved address space of 0x1000 bytes | |
1216 | (0x100 segment units, or 4k). For example if I set an address of | |
1217 | 0xD000, it will use up addresses 0xD000 to 0xD100. | |
1218 | ||
1219 | The memory switches were tested by booting using QEMM386 stealth, | |
1220 | and using LOADHI to see what address automatically became excluded | |
1221 | from the upper memory regions, and then attempting to load ARCETHER | |
1222 | using these addresses. | |
1223 | ||
1224 | I recommend using an ARCnet memory address of 0xD000, and putting | |
1225 | the EMS page frame at 0xC000 while using QEMM stealth mode. That | |
1226 | way, you get contiguous high memory from 0xD100 almost all the way | |
1227 | the end of the megabyte. | |
1228 | ||
1229 | Memory Switch 0 (MS0) didn't seem to work properly when set to OFF | |
1230 | on my card. It could be malfunctioning on my card. Experiment with | |
1231 | it ON first, and if it doesn't work, set it to OFF. (It may be a | |
1232 | modifier for the 0x200 bit?) | |
1233 | ||
1234 | MS Switch No. | |

1332 | ||
1333 | ||
1334 | Setting the Node ID | |
1335 | ------------------- | |
1336 | ||
1337 | The eight switches in SW2 are used to set the node ID. Each node attached | |
1338 | to the network must have an unique node ID which must be different from 0. | |
1339 | Switch 1 (ID0) serves as the least significant bit (LSB). | |
1340 | ||
1341 | The node ID is the sum of the values of all switches set to "1" | |
1342 | These values are: | |
1343 | ||
1344 | Switch | Label | Value | |
1345 | -------|-------|------- | |
1346 | 1 | ID0 | 1 | |
1347 | 2 | ID1 | 2 | |

1373 | ||
1374 | Setting the I/O Base Address | |
1375 | ---------------------------- | |
1376 | ||
1377 | The last three switches in switch block SW1 are used to select one | |
1378 | of eight possible I/O Base addresses using the following table | |
1379 | ||
1380 | ||
1381 | Switch | Hex I/O | |
1382 | 6 7 8 | Address | |
1383 | ------------|-------- | |

1389 | OFF ON OFF | 350 | |
1390 | ON OFF OFF | 380 | |
1391 | OFF OFF OFF | 3E0 | |
1392 | ||
1393 | ||
1394 | Setting the Base Memory (RAM) buffer Address | |
1395 | -------------------------------------------- | |
1396 | ||
1397 | The memory buffer (RAM) requires 2K. The base of this buffer can be | |
1398 | located in any of eight positions. The address of the Boot Prom is | |
1399 | memory base + 8K or memory base + 0x2000. | |
1400 | Switches 1-5 of switch block SW1 select the Memory Base address. | |
1401 | ||
1402 | Switch | Hex RAM | Hex ROM | |
1403 | 1 2 3 4 5 | Address | Address *) | |
1404 | --------------------|---------|----------- | |

1411 | ON ON ON OFF OFF | DC000 | DE000 | |
1412 | ON ON OFF OFF OFF | E0000 | E2000 | |
1413 | ||
1414 | *) To enable the Boot ROM install the jumper JP1 | |
1415 | ||
1416 | Note: Since the switches 1 and 2 are always set to ON it may be possible | |
1417 | that they can be used to add an offset of 2K, 4K or 6K to the base | |
1418 | address, but this feature is not documented in the manual and I | |
1419 | haven't tested it yet. | |
1420 | ||
1421 | ||
1422 | Setting the Interrupt Line | |
1423 | -------------------------- | |
1424 | ||
1425 | To select a hardware interrupt level install one (only one!) of the jumpers | |
1426 | JP2, JP3, JP4, JP5, JP6. JP2 is the default. | |

1584 | Setting the I/O Base Address | |
1585 | ---------------------------- | |
1586 | ||
1587 | The first six switches in switch block SW1 are used to select the I/O Base | |
1588 | address using the following table: | |
1589 | ||
1590 | Switch | Hex I/O | |
1591 | 1 2 3 4 5 6 | Address | |
1592 | ------------------------|-------- | |

1603 | combinations are documented. | |
1604 | ||
1605 | ||
1606 | Setting the Base Memory (RAM) buffer Address | |
1607 | -------------------------------------------- | |
1608 | ||
1609 | The switches 7-10 of switch block SW1 are used to select the Memory | |
1610 | Base address of the RAM (2K) and the PROM. | |
1611 | ||
1612 | Switch | Hex RAM | Hex ROM | |

1619 | Note: Other MEM-Base addresses seem to be selectable, but only the above | |
1620 | combinations are documented. | |
1621 | ||
1622 | ||
1623 | Setting the Interrupt Line | |
1624 | -------------------------- | |
1625 | ||
1626 | To select a hardware interrupt level install one (only one!) of the jumpers | |
1627 | JP3 through JP13 using the following table: | |
1628 | ||
1629 | Jumper | IRQ | |
1630 | -------|----------------- | |
1631 | 3 | 14 | |

1639 | 11 | 6 | |
1640 | 12 | 7 | |
1641 | 13 | 2 (=9) Default! | |
1642 | ||
1643 | Note: - Do not use JP11=IRQ6, it may conflict with your Floppy Disk | |
1644 | Controller | |
1645 | - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL- | |
1646 | Hard Disk, it may conflict with their controllers | |
1647 | ||
1648 | ||
1649 | Setting the Timeout Parameters | |
1650 | ------------------------------ | |
1651 | ||
1652 | The jumpers labeled JP1 and JP2 are used to determine the timeout | |
1653 | parameters. These two jumpers are normally left open. | |

1706 | It seems that the bits are considered in reverse order. Also, you must | |
1707 | observe that some of those addresses are unusual and I didn't probe them; I | |
1708 | used a memory dump in DOS to identify them. For the 00000 configuration and | |
1709 | some others that I didn't write here the card seems to conflict with the | |
1710 | video card (an S3 GENDAC). I leave the full decoding of those addresses to | |

1807 | ||
1808 | Setting the Node ID | |
1809 | ------------------- | |
1810 | ||
1811 | The eight switches in SW2 are used to set the node ID. Each node attached | |
1812 | to the network must have an unique node ID which must not be 0. | |
1813 | Switch 1 (ID0) serves as the least significant bit (LSB). | |
1814 | ||
1815 | Setting one of the switches to OFF means "1", ON means "0". | |
1816 | ||
1817 | The node ID is the sum of the values of all switches set to "1" | |
1818 | These values are: | |
1819 | ||
1820 | Switch | Value | |
1821 | -------|------- | |
1822 | 1 | 1 | |
1823 | 2 | 2 | |
1824 | 3 | 4 | |
1825 | 4 | 8 | |
1826 | 5 | 16 | |
1827 | 6 | 32 | |
1828 | 7 | 64 | |
1829 | 8 | 128 | |
1830 | ||
1831 | Don't set this to 0 or 255; these values are reserved. | |
1832 | ||
1833 | ||
1834 | Setting the I/O Base Address | |
1835 | ---------------------------- | |
1836 | ||
1837 | The switches 1 to 6 of switch block SW1 are used to select one | |
1838 | of 32 possible I/O Base addresses using the following tables | |
1839 | ||
1840 | | Hex | |
1841 | Switch | Value | |
1842 | -------|------- | |
1843 | 1 | 200 | |
1844 | 2 | 100 | |
1845 | 3 | 80 | |
1846 | 4 | 40 | |
1847 | 5 | 20 | |
1848 | 6 | 10 | |
1849 | ||
1850 | The I/O address is sum of all switches set to "1". Remember that | |
1851 | the I/O address space bellow 0x200 is RESERVED for mainboard, so | |
1852 | switch 1 should be ALWAYS SET TO OFF. | |
1853 | ||
1854 | ||
1855 | Setting the Base Memory (RAM) buffer Address | |
1856 | -------------------------------------------- | |
1857 | ||
1858 | The memory buffer (RAM) requires 2K. The base of this buffer can be | |
1859 | located in any of sixteen positions. However, the addresses below | |
1860 | A0000 are likely to cause system hang because there's main RAM. | |
1861 | ||
1862 | Jumpers 7-10 of switch block SW1 select the Memory Base address. | |
1863 | ||
1864 | Switch | Hex RAM | |
1865 | 7 8 9 10 | Address | |
1866 | ----------------|--------- | |
1867 | OFF OFF OFF OFF | F0000 (conflicts with main BIOS) | |
1868 | OFF OFF OFF ON | E0000 | |
1869 | OFF OFF ON OFF | D0000 | |
1870 | OFF OFF ON ON | C0000 (conflicts with video BIOS) | |
1871 | OFF ON OFF OFF | B0000 (conflicts with mono video) | |
1872 | OFF ON OFF ON | A0000 (conflicts with graphics) | |
1873 | ||
1874 | ||
1875 | Setting the Interrupt Line | |
1876 | -------------------------- | |
1877 | ||
1878 | Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means | |
1879 | shorted, OFF means open. | |
1880 | ||
1881 | Jumper | IRQ | |
1882 | 1 2 3 4 5 | | |
1883 | ---------------------------- | |
1884 | ON OFF OFF OFF OFF | 7 | |
1885 | OFF ON OFF OFF OFF | 5 | |
1886 | OFF OFF ON OFF OFF | 4 | |
1887 | OFF OFF OFF ON OFF | 3 | |
1888 | OFF OFF OFF OFF ON | 2 | |
1889 | ||
1890 | ||
1891 | Unknown jumpers & sockets | |
1892 | ------------------------- | |
1893 | ||
1894 | I know nothing about these. I just guess that J16&J17 are timeout | |
1895 | jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and | |
1896 | J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't | |
1897 | guess the purpose. | |

1991 | ||
1992 | ||
1993 | Setting the Base Memory (RAM) buffer Address | |
1994 | -------------------------------------------- | |
1995 | ||
1996 | The memory buffer (RAM) requires 2K. The base of this buffer can be | |
1997 | located in any of eight positions. The address of the Boot Prom is | |
1998 | memory base + 0x2000. | |
1999 | Jumpers 3-5 of switch block SW1 select the Memory Base address. | |
2000 | ||
2001 | Switch | Hex RAM | Hex ROM | |

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

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

2382 | =================== | |
2383 | ||
2384 | I have named this ARCnet card "NONAME", since there is no name of any | |
2385 | manufacturer on the Installation manual nor on the shipping box. The only | |
2386 | hint to the existence of a manufacturer at all is written in copper, | |
2387 | it is "Made in Taiwan" | |

2433 | ||
2434 | ||
2435 | Setting the Node ID | |
2436 | ------------------- | |
2437 | ||
2438 | The eight switches in group SW1 are used to set the node ID. | |
2439 | Each node attached to the network must have an unique node ID which | |
2440 | must be different from 0. | |
2441 | Switch 8 serves as the least significant bit (LSB). | |
2442 | ||
2443 | The node ID is the sum of the values of all switches set to "1" | |
2444 | These values are: | |
2445 | ||
2446 | Switch | Value | |
2447 | -------|------- | |
2448 | 8 | 1 | |
2449 | 7 | 2 | |
2450 | 6 | 4 | |
2451 | 5 | 8 | |
2452 | 4 | 16 | |
2453 | 3 | 32 | |
2454 | 2 | 64 | |

2456 | ||
2457 | Some Examples: | |
2458 | ||
2459 | Switch | Hex | Decimal | |

2474 | ||
2475 | ||
2476 | Setting the I/O Base Address | |
2477 | ---------------------------- | |
2478 | ||
2479 | The first three switches in switch group SW2 are used to select one | |
2480 | of eight possible I/O Base addresses using the following table | |
2481 | ||
2482 | Switch | Hex I/O | |
2483 | 1 2 3 | Address | |
2484 | ------------|-------- | |
2485 | ON ON ON | 260 | |
2486 | ON ON OFF | 290 | |
2487 | ON OFF ON | 2E0 (Manufacturer's default) | |
2488 | ON OFF OFF | 2F0 | |
2489 | OFF ON ON | 300 | |
2490 | OFF ON OFF | 350 | |
2491 | OFF OFF ON | 380 | |
2492 | OFF OFF OFF | 3E0 | |
2493 | ||
2494 | ||
2495 | Setting the Base Memory (RAM) buffer Address | |
2496 | -------------------------------------------- | |
2497 | ||
2498 | The memory buffer requires 2K of a 16K block of RAM. The base of this | |
2499 | 16K block can be located in any of eight positions. | |
2500 | Switches 4-6 of switch group SW2 select the Base of the 16K block. | |
2501 | Within that 16K address space, the buffer may be assigned any one of four | |
2502 | positions, determined by the offset, switches 7 and 8 of group SW2. | |
2503 | ||
2504 | Switch | Hex RAM | Hex ROM | |
2505 | 4 5 6 7 8 | Address | Address *) | |

2547 | *) To enable the 8K Boot PROM install the jumper ROM. | |
2548 | The default is jumper ROM not installed. | |
2549 | ||
2550 | ||
2551 | Setting Interrupt Request Lines (IRQ) | |
2552 | ------------------------------------- | |
2553 | ||
2554 | To select a hardware interrupt level set one (only one!) of the jumpers | |
2555 | IRQ2, IRQ3, IRQ4, IRQ5 or IRQ7. The manufacturer's default is IRQ2. | |
2556 | ||
2557 | ||
2558 | Setting the Timeouts | |
2559 | -------------------- | |
2560 | ||
2561 | The two jumpers labeled ET1 and ET2 are used to determine the timeout | |
2562 | parameters (response and reconfiguration time). Every node in a network | |
2563 | must be set to the same timeout values. | |
2564 | ||
2565 | ET1 ET2 | Response Time (us) | Reconfiguration Time (ms) | |
2566 | --------|--------------------|-------------------------- | |
2567 | Off Off | 78 | 840 (Default) | |
2568 | Off On | 285 | 1680 | |
2569 | On Off | 563 | 1680 | |
2570 | On On | 1130 | 1680 | |
2571 | ||
2572 | On means jumper installed, Off means jumper not installed | |

2575 | NONAME 16-BIT ARCNET | |
2576 | ==================== | |
2577 | ||
2578 | The manual of my 8-Bit NONAME ARCnet Card contains another description | |
2579 | of a 16-Bit Coax / Twisted Pair Card. This description is incomplete, | |
2580 | because there are missing two pages in the manual booklet. (The table | |
2581 | of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside | |
2582 | the booklet there is a different way of counting ... 2-9, 2-10, A-1, | |
2583 | (empty page), 3-1, ..., 3-18, A-1 (again), A-2) | |
2584 | Also the picture of the board layout is not as good as the picture of | |
2585 | 8-Bit card, because there isn't any letter like "SW1" written to the | |
2586 | picture. | |
2587 | Should somebody have such a board, please feel free to complete this | |
2588 | description or to send a mail to me! | |

2684 | Setting the Base Memory (RAM) buffer Address | |
2685 | -------------------------------------------- | |
2686 | ||
2687 | The memory buffer requires 2K of a 16K block of RAM. The base of this | |
2688 | 16K block can be located in any of eight positions. | |
2689 | Switches 6-8 of switch group SW1 select the Base of the 16K block. | |
2690 | Within that 16K address space, the buffer may be assigned any one of four | |
2691 | positions, determined by the offset, switches 4 and 5 of group SW1. | |

2797 | Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not | |
2798 | switches. | |
2799 | ||
2800 | Setting the jumpers to ON means connecting the upper two pins, off the bottom | |
2801 | two - or - in case of IRQ setting, connecting none of them at all. | |
2802 | ||
2803 | Setting the Node ID | |
2804 | ------------------- | |
2805 | ||
2806 | The eight switches in SW2 are used to set the node ID. Each node attached | |
2807 | to the network must have an unique node ID which must not be 0. | |
2808 | Switch 1 (ID0) serves as the least significant bit (LSB). | |
2809 | ||
2810 | Setting one of the switches to Off means "1", On means "0". | |
2811 | ||
2812 | The node ID is the sum of the values of all switches set to "1" | |
2813 | These values are: | |

2967 | up (on) SW1...(switches 1-5) | |
2968 | IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2. | |
2969 | ||
2970 | The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7) | |
2971 | are used to determine the timeout parameters. These two dip switches | |
2972 | are normally left off (down). | |
2973 | ||
2974 | To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM. | |
2975 | The default is jumper ROM not installed. | |
2976 | ||
2977 | ||
2978 | Setting the I/O Base Address | |
2979 | ---------------------------- | |

2999 | ------------------------------------------- | |
3000 | ||
3001 | The memory buffer requires 2K of a 16K block of RAM. The base of this | |
3002 | 16K block can be located in any of eight positions. | |
3003 | Switches 1-3 of switch group SW2 select the Base of the 16K block. | |

3020 | Setting the Node ID | |
3021 | ------------------- | |
3022 | ||
3023 | The eight switches in group SW3 are used to set the node ID. | |
3024 | Each node attached to the network must have an unique node ID which | |
3025 | must be different from 0. | |
3026 | Switch 1 serves as the least significant bit (LSB). | |
3027 | switches in the DOWN position are OFF (0) and in the UP position are ON (1) | |
3028 | ||
3029 | The node ID is the sum of the values of all switches set to "1" | |
3030 | These values are: | |
