CABLING ARCNET NETWORKS
-----------------------
- - Information in this section is from several contributors, including:
- Stephen A. Wood <saw@hallc1.cebaf.gov>
- John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
- Joachim Koenig <jojo@repas.de>
- Vojtech Pavlik <vpav4328@Diana.troja.mff.cuni.cz>
-
- - I, Avery Pennarun, tried to arrange it into something that makes sense
- when all put together. All mistakes, then, are most likely my fault.
- Bug me about them, and they will probably get fixed.
-
-Ideally, according to documentation, ARCnet networks should be connected
-with 93 Ohm cables with 93 Ohm resistors as terminators. I use TV cable and
-no resistors to connect two STAR cards. Blah. Your mileage may vary.
-
-Here's some more specific information about cables, sent in by Joachim
-Koenig (slight touchups by me):
-
- The following cables are valid for ARCnet:
- RG-62 93 Ohm up to 610 m
- RG-59/U 75 Ohm up to 457 m
- RG-11/U 75 Ohm up to 533 m
- IBM Typ 1 150 Ohm up to 200 m
- IBM Typ 3 100 Ohm up to 100 m
-
-So you can see that while 93 Ohms is ideal, you can still go half a
-kilometer with 75 Ohm TV cable. A rule of thumb might be handy here, to
-help you remember:
- Basically any coax cable, up to a ridiculously large distance.
-
-The above applies to all known ARCnet cards. Specific to STAR cards,
-though, Stephen A. Wood has some information:
-
- When I bought my two cards at a garage sale, they came with little
- box with four BNC connectors on the outside. The shields of the
- four connectors are all grounded together, and the center conductors
- were connected by the following resistor network.
-
- |
- |
- R
- |
- ---R-+-R---
- |
- R
- |
- |
-
- Where R is 47 Ohms. A little math shows that if you terminate three
- of the outputs with 90 ohms (A cable or a terminator), the remaining
- input sees 90 Ohms. Therefore this box is impedance matched to 90
- Ohm cable. So this box can be used to connect 2 to 4 nodes
- together.
-
-If you really use your imagination, you can see how the above diagram kind
-of looks like a "star." John Paul Morrison makes a few notes about the
-above:
-
- The "little box with four BNC connectors on the outside" is an
- Arcnet passive hub. They're worth about $5 (just so you don't get
- ripped off).
-
- I don't have specs at my fingertips. Basically, don't use too many
- passive hubs (or none at all, apparently passive hubs are A Bad
- Thing. On the other hand, they're a really cheap way to do things.)
-
- Arcnet active hubs are available; they are analogous to Ethernet
- twisted pair hubs. You can plug either a single station or a passive
- hub into each port on the active hub. If you plug in a passive hub,
- that lets you connect three more stations.
-
-According to Vojtech Pavlik, there shouldn't be more than one passive hub
-between two "active ends", an active end being an active hub or an ARCnet
-card. That makes sense to me.
-
-As for BUS cards, they're even easier (for more than two cards, anyway; you
-can't get much simpler than direct-connecting two STAR cards with a TV
-cable). They work just like Thinnet ethernet; it looks like this:
-
- R------+------+------+------R
- | | |
- NODE NODE NODE
-
-Where R is the terminator as usual, and '+' represents a T connector.
-
-Okay, then, what if you have a combination of BUS cards and STAR cards? You
-probably can't do ANY combination you want, but Vojtech Pavlik explains what
-works for him (WARNING: I, Avery, haven't tried anything this weird myself):
-
- All that I need is to terminate each end with a STAR card. I think I
- can even connect the cards like this:
-
- STAR------+-----+-----STAR
- BUS BUS
-
- Where "-" stands for coax, "+" for T connector, "STAR" for star-type
- arcnet card and BUS for bus-type arcnet cards. I think there will be
- no terminators necessary.
-He also explains (I paraphrase slightly here):
-
- R-+----------STAR
- BUS
-
- In this case, I have to terminate the end with the bus card
- using a terminator. ("R" - terminator, "+" - T connector "-" - coax,
- everything other is probably clear)
-
- [...]
-
- And _MAYBE_ you can do even more complicated and insane combinations
- when just thinking of the STAR card as a BUS one with an inside
- installed terminator. (STAR cards are NOT bus ones with terminator,
- but I believe that they electrically act like them).
-
-And finally, he gives a shortcut for BUS users that are low on supplies:
-
- When you have really short cables (about four meters in total) and have lack
- of terminators or T's you can leave one of the terminators out .... or put
- it in the middle like this:
-
- BUS-----T-----BUS
- R
-
- It's ugly, but it works.
-
-I don't pretend to understand what's happening there, but then again, I
-don't have BUS cards either.

+ARCnet (the classic 2.5 Mbps version) can be connected by two different
+types of cabling: coax and twisted pair. The other ARCnet-type networks
+(100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
+cabling (Type1, Fiber, C1, C4, C5).
+
+For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
+also work fine, because ARCnet is a very stable network. I personally use 75
+Ohm TV antenna cable.
+
+Cards for coax cabling are shipped in two different variants: for BUS and
+STAR network topologies. They are mostly the same. The only difference
+lies in the hybrid chip installed. BUS cards use high impedance output,
+while STAR use low impedance. Low impedance card (STAR) is electrically
+equal to a high impedance one with a terminator installed.
+
+Usually, the ARCnet networks are built up from STAR cards and hubs. There
+are two types of hubs - active and passive. Passive hubs are small boxes
+with four BNC connectors containing four 47 Ohm resistors:
+
+ | | wires
+ R + junction
+-R-+-R- R 47 Ohm resistors
+ R
+ |
+
+The shielding is connected together. Active hubs are much more complicated;
+they are powered and contain electronics to amplify the signal and send it
+to other segments of the net. They usually have eight connectors. Active
+hubs come in two variants - dumb and smart. The dumb variant just
+amplifies, but the smart one decodes to digital and encodes back all packets
+coming through. This is much better if you have several hubs in the net,
+since many dumb active hubs may worsen the signal quality.
+
+And now to the cabling. What you can connect together:
+
+1. A card to a card. This is the simplest way of creating a 2-computer
+ network.
+
+2. A card to a passive hub. Remember that all unused connectors on the hub
+ must be properly terminated with 93 Ohm (or something else if you don't
+ have the right ones) terminators.
+ (Avery's note: oops, I didn't know that. Mine (TV cable) works
+ anyway, though.)
+
+3. A card to an active hub. Here is no need to terminate the unused
+ connectors except some kind of aesthetic feeling. But, there may not be
+ more than eleven active hubs between any two computers. That of course
+ doesn't limit the number of active hubs on the network.
+
+4. An active hub to another.
+
+5. An active hub to passive hub.
+
+Remember, that you can not connect two passive hubs together. The power loss
+implied by such connection is too high for the net to operate reliably.
+
+An example of a typical ARCnet network:
+
+ R S - STAR type card
+ S------H--------A-------S R - Terminator
+ | | H - Hub
+ | | A - Active hub
+ | S----H----S
+ S |
+ |
+ S
+
+The BUS topology is very similar to the one used by Ethernet. The only
+difference is in cable and terminators: they should be 93 Ohm. Ethernet
+uses 50 Ohm impedance. You use T connectors to put the computers on a single
+line of cable, the bus. You have to put terminators at both ends of the
+cable. A typical BUS ARCnet network looks like:
+
+ RT----T------T------T------T------TR
+ B B B B B B
+
+ B - BUS type card
+ R - Terminator
+ T - T connector
+
+But that is not all! The two types can be connected together. According to
+the official documentation the only way of conecting them is using an active
+hub:
+
+ A------T------T------TR
+ | B B B
+ S---H---S
+ |
+ S
+
+The official docs also state that you can use STAR cards at the ends of
+BUS network in place of a BUS card and a terminator:
+
+ S------T------T------S
+ B B
+
+But, according to my own experiments, you can simply hang a BUS type card
+anywhere in middle of a cable in a STAR topology network. And more - you
+can use the bus card in place of any star card if you use a terminator. Then
+you can build very complicated networks fulfilling all your needs! An
+example:
+
+ S
+ |
+ RT------T-------T------H------S
+ B B B |
+ | R
+ S------A------T-------T-------A-------H------TR
+ | B B | | B
+ | S BT |
+ | | | S----A-----S
+ S------H---A----S | |
+ | | S------T----H---S |
+ S S B R S
+
+A basicaly different cabling scheme is used with Twisted Pair cabling. Each
+of the TP cards has two RJ (phone-cord style) connectors. The cards are
+then daisy-chained together using a cable connecting every two neighboring
+cards. The ends are terminated with RJ 93 Ohm terminators which plug into
+the empty connectors of cards on the ends of the chain. An example:
+
+ ___________ ___________
+ _R_|_ _|_|_ _|_R_
+ | | | | | |
+ |Card | |Card | |Card |
+ |_____| |_____| |_____|
+
+
+There are also hubs for the TP topology. There is nothing difficult
+involved in using them; you just connect a TP chain to a hub on any end or
+even at both. This way you can create almost any network configuration.
+The maximum of 11 hubs between any two computers on the net applies here as
+well. An example:
+
+ RP-------P--------P--------H-----P------P-----PR
+ |
+ RP-----H--------P--------H-----P------PR
+ | |
+ PR PR
+
+ R - RJ Terminator
+ P - TP Card
+ H - TP Hub
+
+Like any network, ARCnet has a limited cable length. These are the maximum
+cable lengths between two active ends (an active end being an active hub or
+a STAR card).
+
+ RG-62 93 Ohm up to 650 m
+ RG-59/U 75 Ohm up to 457 m
+ RG-11/U 75 Ohm up to 533 m
+ IBM Type 1 150 Ohm up to 200 m
+ IBM Type 3 100 Ohm up to 100 m
+
+The maximum length of all cables connected to a passive hub is limited to 65
+meters for RG-62 cabling; less for others. You can see that using passive
+hubs in a large network is a bad idea. The maximum length of a single "BUS
+Trunk" is about 300 meters for RG-62. The maximum distance between the two
+most distant points of the net is limited to 3000 meters. The maximum length
+of a TP cable between two cards/hubs is 650 meters.

+
+Setting the Node ID
+-------------------
+
+The eight switches in SW2 are used to set the node ID. Each node attached
+to the network must have an unique node ID which must not be 0.
+Switch 1 (ID0) serves as the least significant bit (LSB).
+
+Setting one of the switches to OFF means "1", ON means "0".
+
+The node ID is the sum of the values of all switches set to "1"
+These values are:
+
+ Switch | Value
+ -------|-------
+ 1 | 1
+ 2 | 2
+ 3 | 4
+ 4 | 8
+ 5 | 16
+ 6 | 32
+ 7 | 64
+ 8 | 128
+
+Don't set this to 0 or 255; these values are reserved.
+
+
+Setting the I/O Base Address
+----------------------------
+
+The switches 1 to 6 of switch block SW1 are used to select one
+of 32 possible I/O Base addresses using the followig tables
+
+ | Hex
+ Switch | Value
+ -------|-------
+ 1 | 200
+ 2 | 100
+ 3 | 80
+ 4 | 40
+ 5 | 20
+ 6 | 10
+
+The I/O address is sum of all switches set to "1". Remember that
+the I/O address space bellow 0x200 is RESERVED for mainboard, so
+switch 1 should be ALWAYS SET TO OFF.
+
+
+Setting the Base Memory (RAM) buffer Address
+--------------------------------------------
+
+The memory buffer (RAM) requires 2K. The base of this buffer can be
+located in any of sixteen positions. However, the addresses below
+A0000 are likely to cause system hang because there's main RAM.
+
+Jumpers 7-10 of switch block SW1 select the Memory Base address.
+
+ Switch | Hex RAM
+ 7 8 9 10 | Address
+ ----------------|---------
+ OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
+ OFF OFF OFF ON | E0000
+ OFF OFF ON OFF | D0000
+ OFF OFF ON ON | C0000 (conflicts with video BIOS)
+ OFF ON OFF OFF | B0000 (conflicts with mono video)
+ OFF ON OFF ON | A0000 (conflicts with graphics)
+
+
+Setting the Interrupt Line
+--------------------------
+
+Jumpers 1-5 of the jumper block J1 controll the IRQ level. ON means
+shorted, OFF means open.

+-------------------------
+
+I know nothing about these. I just guess that J16&J17 are timeout
+jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
+J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't

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

+
+SW1: Timeouts, Interrupt and ROM
+---------------------------------
+
+To select a hardware interrupt level set one (only one!) of the dip switches
+up (on) SW1...(switches 1-5)
+IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
+
+The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
+are used to determine the timeout parameters. These two dip switches
+are normally left off (down).
+
+ To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
+ The default is jumper ROM not installed.
+
+
+Setting the I/O Base Address
+----------------------------
+
+The last three switches in switch group SW2 are used to select one
+of eight possible I/O Base addresses using the following table
+
+
+ Switch | Hex I/O
+ 4 5 6 | Address
+ -------|--------
+ 0 0 0 | 260
+ 0 0 1 | 290
+ 0 1 0 | 2E0 (Manufacturer's default)
+ 0 1 1 | 2F0
+ 1 0 0 | 300
+ 1 0 1 | 350
+ 1 1 0 | 380
+ 1 1 1 | 3E0
+
+
+Setting the Base Memory Address (RAM & ROM)
+-------------------------------------------
+
+The memory buffer requires 2K of a 16K block of RAM. The base of this
+16K block can be located in any of eight positions.
+Switches 1-3 of switch group SW2 select the Base of the 16K block.
+(0 = DOWN, 1 = UP)
+I could, however, only verify two settings...
+
+ Switch| Hex RAM | Hex ROM
+ 1 2 3 | Address | Address
+ ------|---------|-----------
+ 0 0 0 | E0000 | E2000
+ 0 0 1 | D0000 | D2000 (Manufacturer's default)
+ 0 1 0 | ????? | ?????
+ 0 1 1 | ????? | ?????
+ 1 0 0 | ????? | ?????
+ 1 0 1 | ????? | ?????
+ 1 1 0 | ????? | ?????
+ 1 1 1 | ????? | ?????
+
+
+Setting the Node ID
+-------------------
+
+The eight switches in group SW3 are used to set the node ID.
+Each node attached to the network must have an unique node ID which
+must be diffrent from 0.
+Switch 1 serves as the least significant bit (LSB).
+switches in the DOWN position are OFF (0) and in the UP position are ON (1)
+
+The node ID is the sum of the values of all switches set to "1"
+These values are:
+ Switch | Value
+ -------|-------
+ 1 | 1
+ 2 | 2
+ 3 | 4
+ 4 | 8
+ 5 | 16
+ 6 | 32
+ 7 | 64
+ 8 | 128
+
+Some Examples:
+
+ Switch# | Hex | Decimal
+8 7 6 5 4 3 2 1 | Node ID | Node ID
+----------------|---------|---------
+0 0 0 0 0 0 0 0 | not allowed <-.
+0 0 0 0 0 0 0 1 | 1 | 1 |
+0 0 0 0 0 0 1 0 | 2 | 2 |
+0 0 0 0 0 0 1 1 | 3 | 3 |
+ . . . | | |
+0 1 0 1 0 1 0 1 | 55 | 85 |
+ . . . | | + Don't use 0 or 255!
+1 0 1 0 1 0 1 0 | AA | 170 |
+ . . . | | |
+1 1 1 1 1 1 0 1 | FD | 253 |
+1 1 1 1 1 1 1 0 | FE | 254 |
