21 | Introduction to ARCnet |
22 | ====================== | |
1da177e4 LT |
23 | |
24 | ARCnet is a network type which works in a way similar to popular Ethernet | |
25 | networks but which is also different in some very important ways. | |
26 | ||
27 | First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps | |
28 | (slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact, | |
29 | there are others as well, but these are less common. The different hardware | |
30 | types, as far as I'm aware, are not compatible and so you cannot wire a | |
31 | 100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does | |
32 | work with 100 Mbps cards, but I haven't been able to verify this myself, | |
33 | since I only have the 2.5 Mbps variety. It is probably not going to saturate | |
34 | your 100 Mbps card. Stop complaining. :) | |
35 | ||
36 | You also cannot connect an ARCnet card to any kind of Ethernet card and | |
aa92320b | 37 | expect it to work. |
1da177e4 LT |
38 | |
39 | There are two "types" of ARCnet - STAR topology and BUS topology. This | |
40 | refers to how the cards are meant to be wired together. According to most | |
41 | available documentation, you can only connect STAR cards to STAR cards and | |
42 | BUS cards to BUS cards. That makes sense, right? Well, it's not quite | |
43 | true; see below under "Cabling." | |
44 | ||
45 | Once you get past these little stumbling blocks, ARCnet is actually quite a | |
46 | well-designed standard. It uses something called "modified token passing" | |
47 | which makes it completely incompatible with so-called "Token Ring" cards, | |
48 | but which makes transfers much more reliable than Ethernet does. In fact, | |
49 | ARCnet will guarantee that a packet arrives safely at the destination, and | |
50 | even if it can't possibly be delivered properly (ie. because of a cable | |
51 | break, or because the destination computer does not exist) it will at least | |
52 | tell the sender about it. | |
53 | ||
54 | Because of the carefully defined action of the "token", it will always make | |
55 | a pass around the "ring" within a maximum length of time. This makes it | |
56 | useful for realtime networks. | |
57 | ||
58 | In addition, all known ARCnet cards have an (almost) identical programming | |
59 | interface. This means that with one ARCnet driver you can support any | |
60 | card, whereas with Ethernet each manufacturer uses what is sometimes a | |
61 | completely different programming interface, leading to a lot of different, | |
62 | sometimes very similar, Ethernet drivers. Of course, always using the same | |
63 | programming interface also means that when high-performance hardware | |
64 | facilities like PCI bus mastering DMA appear, it's hard to take advantage of | |
65 | them. Let's not go into that. | |
66 | ||
67 | One thing that makes ARCnet cards difficult to program for, however, is the | |
68 | limit on their packet sizes; standard ARCnet can only send packets that are | |
69 | up to 508 bytes in length. This is smaller than the Internet "bare minimum" | |
70 | of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra | |
71 | level of encapsulation is defined by RFC1201, which I call "packet | |
72 | splitting," that allows "virtual packets" to grow as large as 64K each, | |
73 | although they are generally kept down to the Ethernet-style 1500 bytes. | |
74 | ||

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

82 | Cabling ARCnet Networks |
83 | ======================= | |
84 | ||
85 | This section was rewritten by | |
86 | ||
87 | Vojtech Pavlik <vojtech@suse.cz> | |
1da177e4 | 88 | |
1da177e4 | 89 | using information from several people, including: |
aa92320b MCC |
90 | |
91 | - Avery Pennraun <apenwarr@worldvisions.ca> | |
92 | - Stephen A. Wood <saw@hallc1.cebaf.gov> | |
93 | - John Paul Morrison <jmorriso@bogomips.ee.ubc.ca> | |
94 | - Joachim Koenig <jojo@repas.de> | |
95 | ||
1da177e4 LT |
96 | and Avery touched it up a bit, at Vojtech's request. |
97 | ||
98 | ARCnet (the classic 2.5 Mbps version) can be connected by two different | |
99 | types of cabling: coax and twisted pair. The other ARCnet-type networks | |
100 | (100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of | |
101 | cabling (Type1, Fiber, C1, C4, C5). | |
102 | ||
103 | For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables | |
104 | also work fine, because ARCnet is a very stable network. I personally use 75 | |
105 | Ohm TV antenna cable. | |
106 | ||
107 | Cards for coax cabling are shipped in two different variants: for BUS and | |
108 | STAR network topologies. They are mostly the same. The only difference | |
109 | lies in the hybrid chip installed. BUS cards use high impedance output, | |
110 | while STAR use low impedance. Low impedance card (STAR) is electrically | |
111 | equal to a high impedance one with a terminator installed. | |
112 | ||
113 | Usually, the ARCnet networks are built up from STAR cards and hubs. There | |
114 | are two types of hubs - active and passive. Passive hubs are small boxes | |
aa92320b | 115 | with four BNC connectors containing four 47 Ohm resistors:: |
1da177e4 | 116 | |
aa92320b MCC |
117 | | | wires |
118 | R + junction | |
119 | -R-+-R- R 47 Ohm resistors | |
120 | R | |
121 | | | |
1da177e4 LT |
122 | |
123 | The shielding is connected together. Active hubs are much more complicated; | |
124 | they are powered and contain electronics to amplify the signal and send it | |
125 | to other segments of the net. They usually have eight connectors. Active | |
126 | hubs come in two variants - dumb and smart. The dumb variant just | |
127 | amplifies, but the smart one decodes to digital and encodes back all packets | |
128 | coming through. This is much better if you have several hubs in the net, | |
129 | since many dumb active hubs may worsen the signal quality. | |
130 | ||
131 | And now to the cabling. What you can connect together: | |
132 | ||
133 | 1. A card to a card. This is the simplest way of creating a 2-computer | |
134 | network. | |
135 | ||
136 | 2. A card to a passive hub. Remember that all unused connectors on the hub | |
137 | must be properly terminated with 93 Ohm (or something else if you don't | |
138 | have the right ones) terminators. | |
aa92320b MCC |
139 | |
140 | (Avery's note: oops, I didn't know that. Mine (TV cable) works | |
1da177e4 LT |
141 | anyway, though.) |
142 | ||
143 | 3. A card to an active hub. Here is no need to terminate the unused | |
144 | connectors except some kind of aesthetic feeling. But, there may not be | |
145 | more than eleven active hubs between any two computers. That of course | |
146 | doesn't limit the number of active hubs on the network. | |
aa92320b | 147 | |
1da177e4 LT |
148 | 4. An active hub to another. |
149 | ||
150 | 5. An active hub to passive hub. | |
151 | ||
84eb8d06 | 152 | Remember that you cannot connect two passive hubs together. The power loss |
1da177e4 LT |
153 | implied by such a connection is too high for the net to operate reliably. |
154 | ||
aa92320b | 155 | An example of a typical ARCnet network:: |
1da177e4 | 156 | |
aa92320b | 157 | R S - STAR type card |
1da177e4 | 158 | S------H--------A-------S R - Terminator |
aa92320b MCC |

162 | S | | |
163 | | | |
164 | S | |
165 | ||
1da177e4 LT |
166 | The BUS topology is very similar to the one used by Ethernet. The only |
167 | difference is in cable and terminators: they should be 93 Ohm. Ethernet | |
168 | uses 50 Ohm impedance. You use T connectors to put the computers on a single | |
169 | line of cable, the bus. You have to put terminators at both ends of the | |
aa92320b | 170 | cable. A typical BUS ARCnet network looks like:: |
1da177e4 LT |
171 | |
172 | RT----T------T------T------T------TR | |
173 | B B B B B B | |
174 | ||
175 | B - BUS type card | |
176 | R - Terminator | |
177 | T - T connector | |
178 | ||
179 | But that is not all! The two types can be connected together. According to | |
180 | the official documentation the only way of connecting them is using an active | |
aa92320b | 181 | hub:: |
1da177e4 | 182 | |
aa92320b MCC |
183 | A------T------T------TR |
184 | | B B B | |
1da177e4 | 185 | S---H---S |
aa92320b MCC |
186 | | |
187 | S | |
1da177e4 LT |
188 | |
189 | The official docs also state that you can use STAR cards at the ends of | |
aa92320b | 190 | BUS network in place of a BUS card and a terminator:: |
1da177e4 LT |
191 | |
192 | S------T------T------S | |
aa92320b | 193 | B B |
1da177e4 LT |
194 | |
195 | But, according to my own experiments, you can simply hang a BUS type card | |
196 | anywhere in middle of a cable in a STAR topology network. And more - you | |
197 | can use the bus card in place of any star card if you use a terminator. Then | |
198 | you can build very complicated networks fulfilling all your needs! An | |
aa92320b MCC |
199 | example:: |

214 | A basically different cabling scheme is used with Twisted Pair cabling. Each |
215 | of the TP cards has two RJ (phone-cord style) connectors. The cards are | |
216 | then daisy-chained together using a cable connecting every two neighboring | |
217 | cards. The ends are terminated with RJ 93 Ohm terminators which plug into | |
aa92320b | 218 | the empty connectors of cards on the ends of the chain. An example:: |
1da177e4 | 219 | |

223 | |Card | |Card | |Card | | |
224 | |_____| |_____| |_____| | |
1da177e4 LT |
225 | |
226 | ||
227 | There are also hubs for the TP topology. There is nothing difficult | |
228 | involved in using them; you just connect a TP chain to a hub on any end or | |
aa92320b | 229 | even at both. This way you can create almost any network configuration. |
1da177e4 | 230 | The maximum of 11 hubs between any two computers on the net applies here as |
aa92320b | 231 | well. An example:: |
1da177e4 LT |
232 | |
233 | RP-------P--------P--------H-----P------P-----PR | |
aa92320b | 234 | | |
1da177e4 | 235 | RP-----H--------P--------H-----P------PR |
aa92320b MCC |
236 | | | |
237 | PR PR | |
1da177e4 LT |
238 | |
239 | R - RJ Terminator | |
240 | P - TP Card | |
241 | H - TP Hub | |
242 | ||
243 | Like any network, ARCnet has a limited cable length. These are the maximum | |
244 | cable lengths between two active ends (an active end being an active hub or | |
245 | a STAR card). | |
246 | ||
aa92320b | 247 | ========== ======= =========== |
1da177e4 LT |
248 | RG-62 93 Ohm up to 650 m |
249 | RG-59/U 75 Ohm up to 457 m | |
250 | RG-11/U 75 Ohm up to 533 m | |
251 | IBM Type 1 150 Ohm up to 200 m | |
252 | IBM Type 3 100 Ohm up to 100 m | |
aa92320b | 253 | ========== ======= =========== |
1da177e4 LT |
254 | |
255 | The maximum length of all cables connected to a passive hub is limited to 65 | |
256 | meters for RG-62 cabling; less for others. You can see that using passive | |
257 | hubs in a large network is a bad idea. The maximum length of a single "BUS | |
258 | Trunk" is about 300 meters for RG-62. The maximum distance between the two | |
259 | most distant points of the net is limited to 3000 meters. The maximum length | |
260 | of a TP cable between two cards/hubs is 650 meters. | |

263 | Setting the Jumpers |
264 | =================== | |
1da177e4 LT |
265 | |
266 | All ARCnet cards should have a total of four or five different settings: | |
267 | ||
268 | - the I/O address: this is the "port" your ARCnet card is on. Probed | |
269 | values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If | |
270 | your card has additional ones, which is possible, please tell me.) This | |
271 | should not be the same as any other device on your system. According to | |
272 | a doc I got from Novell, MS Windows prefers values of 0x300 or more, | |
273 | eating net connections on my system (at least) otherwise. My guess is | |
274 | this may be because, if your card is at 0x2E0, probing for a serial port | |
275 | at 0x2E8 will reset the card and probably mess things up royally. | |
aa92320b | 276 | |
1da177e4 LT |
277 | - Avery's favourite: 0x300. |
278 | ||
279 | - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7. | |
aa92320b MCC |
280 | on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15. |
281 | ||
1da177e4 LT |
282 | Make sure this is different from any other card on your system. Note |
283 | that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can | |
284 | "cat /proc/interrupts" for a somewhat complete list of which ones are in | |
285 | use at any given time. Here is a list of common usages from Vojtech | |
286 | Pavlik <vojtech@suse.cz>: | |
aa92320b MCC |
287 | |
288 | ("Not on bus" means there is no way for a card to generate this | |
1da177e4 | 289 | interrupt) |
aa92320b MCC |
290 | |
291 | ====== ========================================================= | |
292 | IRQ 0 Timer 0 (Not on bus) | |
293 | IRQ 1 Keyboard (Not on bus) | |
294 | IRQ 2 IRQ Controller 2 (Not on bus, nor does interrupt the CPU) | |
295 | IRQ 3 COM2 | |
296 | IRQ 4 COM1 | |
297 | IRQ 5 FREE (LPT2 if you have it; sometimes COM3; maybe PLIP) | |
298 | IRQ 6 Floppy disk controller | |
299 | IRQ 7 FREE (LPT1 if you don't use the polling driver; PLIP) | |
300 | IRQ 8 Realtime Clock Interrupt (Not on bus) | |
301 | IRQ 9 FREE (VGA vertical sync interrupt if enabled) | |
302 | IRQ 10 FREE | |
303 | IRQ 11 FREE | |
304 | IRQ 12 FREE | |
305 | IRQ 13 Numeric Coprocessor (Not on bus) | |
306 | IRQ 14 Fixed Disk Controller | |
307 | IRQ 15 FREE (Fixed Disk Controller 2 if you have it) | |
308 | ====== ========================================================= | |
309 | ||
310 | ||
311 | .. note:: | |
312 | ||
313 | IRQ 9 is used on some video cards for the "vertical retrace" | |
314 | interrupt. This interrupt would have been handy for things like | |
315 | video games, as it occurs exactly once per screen refresh, but | |
316 | unfortunately IBM cancelled this feature starting with the original | |
317 | VGA and thus many VGA/SVGA cards do not support it. For this | |
318 | reason, no modern software uses this interrupt and it can almost | |
319 | always be safely disabled, if your video card supports it at all. | |
320 | ||
1da177e4 LT |
321 | If your card for some reason CANNOT disable this IRQ (usually there |
322 | is a jumper), one solution would be to clip the printed circuit | |
323 | contact on the board: it's the fourth contact from the left on the | |
324 | back side. I take no responsibility if you try this. | |
325 | ||
326 | - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though. | |
327 | ||
328 | - the memory address: Unlike most cards, ARCnets use "shared memory" for | |
329 | copying buffers around. Make SURE it doesn't conflict with any other | |
330 | used memory in your system! | |
aa92320b MCC |
331 | |
332 | :: | |
333 | ||
1da177e4 | 334 | A0000 - VGA graphics memory (ok if you don't have VGA) |
aa92320b MCC |
335 | B0000 - Monochrome text mode |
336 | C0000 \ One of these is your VGA BIOS - usually C0000. | |
337 | E0000 / | |
338 | F0000 - System BIOS | |
1da177e4 LT |
339 | |
340 | Anything less than 0xA0000 is, well, a BAD idea since it isn't above | |
341 | 640k. | |
aa92320b | 342 | |
1da177e4 LT |
343 | - Avery's favourite: 0xD0000 |
344 | ||
345 | - the station address: Every ARCnet card has its own "unique" network | |
346 | address from 0 to 255. Unlike Ethernet, you can set this address | |
347 | yourself with a jumper or switch (or on some cards, with special | |
348 | software). Since it's only 8 bits, you can only have 254 ARCnet cards | |
349 | on a network. DON'T use 0 or 255, since these are reserved (although | |
350 | neat stuff will probably happen if you DO use them). By the way, if you | |
351 | haven't already guessed, don't set this the same as any other ARCnet on | |
352 | your network! | |
aa92320b | 353 | |
1da177e4 LT |
354 | - Avery's favourite: 3 and 4. Not that it matters. |
355 | ||
356 | - There may be ETS1 and ETS2 settings. These may or may not make a | |
357 | difference on your card (many manuals call them "reserved"), but are | |
358 | used to change the delays used when powering up a computer on the | |
359 | network. This is only necessary when wiring VERY long range ARCnet | |
360 | networks, on the order of 4km or so; in any case, the only real | |
361 | requirement here is that all cards on the network with ETS1 and ETS2 | |
362 | jumpers have them in the same position. Chris Hindy <chrish@io.org> | |
363 | sent in a chart with actual values for this: | |

394 | The following is all the specific information people have sent me about | |
395 | their own particular ARCnet cards. It is officially a mess, and contains | |
396 | huge amounts of duplicated information. I have no time to fix it. If you | |
397 | want to, PLEASE DO! Just send me a 'diff -u' of all your changes. | |

403 | ||
404 | If your model isn't listed and/or has different settings, PLEASE PLEASE | |
405 | tell me. I had to figure mine out without the manual, and it WASN'T FUN! | |

459 | About the jumpers: On my PC130 there is one more jumper, located near the | |
aa92320b | 460 | cable-connector and it's for changing to star or bus topology; |
1da177e4 LT |
461 | closed: star - open: bus |
462 | On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI | |
463 | and another with ALE,LA17,LA18,LA19 these are undocumented.. | |

477 | - special thanks to Timo Hilbrink <timoh@xs4all.nl> for noting that PC120, | |
aa92320b | 478 | 130, 500, and 600 all have the same switches as Avery's PC100. |
1da177e4 LT |
479 | PC500/600 have several extra, undocumented pins though. (?) |
480 | - PC110 settings were verified by Stephen A. Wood <saw@cebaf.gov> | |
481 | - Also, the JP- and S-numbers probably don't match your card exactly. Try | |
482 | to find jumpers/switches with the same number of settings - it's | |
483 | probably more reliable. | |

723 | Setting the Timeouts and Interrupt | |
aa92320b | 724 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
1da177e4 | 725 | |
aa92320b | 726 | The jumpers labeled EXT1 and EXT2 are used to determine the timeout |
1da177e4 LT |
727 | parameters. These two jumpers are normally left open. |
728 | ||
729 | To select a hardware interrupt level set one (only one!) of the jumpers | |
730 | IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2. | |

733 | Configuring the PC130E for Star or Bus Topology | |
aa92320b | 734 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
1da177e4 | 735 | |
aa92320b | 736 | The single jumper labeled STAR is used to configure the PC130E board for |
1da177e4 | 737 | star or bus topology. |
aa92320b | 738 | When the jumper is installed, the board may be used in a star network, when |
1da177e4 LT |
739 | it is removed, the board can be used in a bus topology. |

742 | Diagnostic LEDs | |
aa92320b | 743 | ^^^^^^^^^^^^^^^ |
1da177e4 LT |
744 | |
745 | Two diagnostic LEDs are visible on the rear bracket of the board. | |
746 | The green LED monitors the network activity: the red one shows the | |
aa92320b | 747 | board activity:: |

761 | ||
762 | ||
aa92320b | 763 | .. note:: |
1da177e4 | 764 | |
aa92320b | 765 | There is another Version of the PC500 called Short Version, which |
1da177e4 LT |
766 | is different in hard- and software! The most important differences |
767 | are: | |
aa92320b | 768 | |
1da177e4 LT |
769 | - The long board has no Shared memory. |
770 | - On the long board the selection of the interrupt is done by binary | |
aa92320b MCC |
771 | coded switch, on the short board directly by jumper. |
772 | ||
1da177e4 | 773 | [Avery's note: pay special attention to that: the long board HAS NO SHARED |
aa92320b | 774 | MEMORY. This means the current Linux-ARCnet driver can't use these cards. |
1da177e4 LT |
775 | I have obtained a PC500Longboard and will be doing some experiments on it in |
776 | the future, but don't hold your breath. Thanks again to Juergen Seifert for | |
777 | his advice about this!] | |

790 | to RG-62/U coax cable. | |
791 | The board is designed both for point-to-point connection in star networks | |
792 | and for connection to bus networks. | |
793 | ||
794 | The PC550 is equipped with two modular RJ11-type jacks for connection | |
795 | to twisted pair wiring. | |
796 | It can be used in a star or a daisy-chained (BUS) network. | |

845 | Setting the Node ID | |
aa92320b | 846 | ^^^^^^^^^^^^^^^^^^^ |
1da177e4 LT |
847 | |
848 | The eight switches in group SW3 are used to set the node ID. Each node | |
aa92320b | 849 | attached to the network must have an unique node ID which must be |
1da177e4 LT |
850 | different from 0. |
851 | Switch 1 serves as the least significant bit (LSB). | |
852 | ||
aa92320b MCC |
853 | The node ID is the sum of the values of all switches set to "1" |
854 | These values are:: | |

aa92320b MCC |
932 | Switches seven through ten of switch group SW1 are used to select the |
933 | interrupt level. The interrupt level is binary coded, so selections | |
1da177e4 LT |
934 | from 0 to 15 would be possible, but only the following eight values will |
935 | be supported: 3, 4, 5, 7, 9, 10, 11, 12. | |

1da177e4 | 954 | |
aa92320b | 955 | The two jumpers JP2 (1-4) are used to determine the timeout parameters. |
1da177e4 LT |
956 | These two jumpers are normally left open. |
957 | Refer to the COM9026 Data Sheet for alternate configurations. | |

aa92320b | 961 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
1da177e4 | 962 | |
aa92320b | 963 | The single jumper labeled JP6 is used to configure the PC500 board for |
1da177e4 | 964 | star or bus topology. |
aa92320b | 965 | When the jumper is installed, the board may be used in a star network, when |
1da177e4 LT |
966 | it is removed, the board can be used in a bus topology. |

969 | Diagnostic LEDs | |

1da177e4 LT |
971 | |
972 | Two diagnostic LEDs are visible on the rear bracket of the board. | |

989 | Note: this data is gathered by experimenting and looking at info of other |
990 | cards. However, I'm sure I got 99% of the settings right. | |
991 | ||
992 | The SMC710 card resembles the PC270 card, but is much more basic (i.e. no | |
aa92320b | 993 | 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. | |

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. | |
aa92320b | 1036 | |
1da177e4 LT |

1da177e4 LT |
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: | |
aa92320b | 1157 | |
1da177e4 | 1158 | There is a jumper array at the bottom of the card, near the edge |
aa92320b MCC |
1159 | connector. This array is labelled J1. They control the IRQs and |
1160 | something else. Put only one jumper on the IRQ pins. | |
1da177e4 LT |
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, | |
aa92320b MCC |
1166 | since it was already there when I got the card. I don't know what |
1167 | this jumper is for though. | |

1169 | There is a two-jumper array for J3. I don't know what it is for, | |
aa92320b MCC |
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:: | |

1195 | - If using coax cable in a bus topology the J4 jumper must be removed; | |
1196 | place it on one pin. | |
1197 | ||
aa92320b | 1198 | - If using bus topology with twisted pair wiring move the J3 |
1da177e4 LT |
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. | |

1208 | DIP Switches: | |
1209 | ||
1210 | The DIP switches accessible on the accessible end of the card while | |
aa92320b MCC |
1211 | it is installed, is used to set the ARCnet address. There are 8 |
1212 | switches. Use an address from 1 to 254 | |

aa92320b | 1225 | ========== ========================= |
1da177e4 LT |
1226 | |
1227 | There is another array of eight DIP switches at the top of the | |
aa92320b MCC |
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. | |
1da177e4 LT |
1231 | |
1232 | This was difficult to test by trial and error, and the I/O addresses | |
aa92320b MCC |
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. | |
1da177e4 LT |
1237 | |
1238 | Also, the address 0x3D0 seem to have a special meaning, since the | |
aa92320b MCC |
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. | |

1257 | |
1258 | The memory switches set a reserved address space of 0x1000 bytes | |
aa92320b MCC |
1259 | (0x100 segment units, or 4k). For example if I set an address of |
1260 | 0xD000, it will use up addresses 0xD000 to 0xD100. | |
1da177e4 LT |
1261 | |
1262 | The memory switches were tested by booting using QEMM386 stealth, | |
aa92320b MCC |
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. | |
1da177e4 LT |
1266 | |
1267 | I recommend using an ARCnet memory address of 0xD000, and putting | |
aa92320b MCC |
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. | |
1da177e4 LT |
1271 | |
1272 | Memory Switch 0 (MS0) didn't seem to work properly when set to OFF | |
aa92320b MCC |
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?) | |

1da177e4 LT |
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 | ||
aa92320b | 1381 | The node ID is the sum of the values of all switches set to "1" |
1da177e4 LT |

1da177e4 | 1438 | |
aa92320b | 1439 | The memory buffer (RAM) requires 2K. The base of this buffer can be |
1da177e4 LT |
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. | |

1461 | ||
1462 | Since the switches 1 and 2 are always set to ON it may be possible | |
1da177e4 LT |
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. | |

1585 | Setting the Node ID | |
aa92320b | 1586 | ^^^^^^^^^^^^^^^^^^^ |
1da177e4 LT |
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 | ||
aa92320b MCC |
1592 | The node ID is the sum of the values of all switches set to "1" |
1593 | These values are:: | |
1da177e4 LT |
1594 | |
1595 | Switch | Label | Value | |

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 | |

aa92320b | 1863 | ^^^^^^^^^^^^^^^^^^^ |
1da177e4 LT |
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" | |
aa92320b | 1872 | These values are:: |
1da177e4 LT |
1873 | |
1874 | Switch | Value | |

1888 | Setting the I/O Base Address | |
aa92320b | 1889 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
1da177e4 LT |
1890 | |
1891 | The switches 1 to 6 of switch block SW1 are used to select one | |
aa92320b MCC |
1892 | of 32 possible I/O Base addresses using the following tables:: |
1893 | ||
1894 | | Hex | |
1da177e4 LT |

1901 | 5 | 20 | |
1902 | 6 | 10 | |
1da177e4 LT |
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 | |
aa92320b | 1906 | switch 1 should be ALWAYS SET TO OFF. |
1da177e4 LT |

1909 | Setting the Base Memory (RAM) buffer Address | |
aa92320b | 1910 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
1da177e4 LT |
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 | ||
aa92320b | 1916 | Jumpers 7-10 of switch block SW1 select the Memory Base address:: |

1932 | Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means |
1933 | shorted, OFF means open:: | |

aa92320b | 1946 | ^^^^^^^^^^^^^^^^^^^^^^^^^ |
1da177e4 LT |
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. | |

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. | |

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. | |

2833 | I have named this ARCnet card "NONAME", since I got only the card with | |
aa92320b | 2834 | no manual at all and the only text identifying the manufacturer is |
1da177e4 LT |
2835 | "MADE IN TAIWAN R.O.C" printed on the card. |
