  12. some cabling tips, and a listing of all jumper settings I can find. Please

  15. Introduction to ARCnet
  16. ======================
  17. ARCnet is a network type which works in a way similar to popular Ethernet
  18. networks but which is also different in some very important ways.
  19. First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
  20. (slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
  21. there are others as well, but these are less common. The different hardware
  22. types, as far as I'm aware, are not compatible and so you cannot wire a
  23. 100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
  24. work with 100 Mbps cards, but I haven't been able to verify this myself,
  25. since I only have the 2.5 Mbps variety. It is probably not going to saturate
  26. your 100 Mbps card. Stop complaining. :)
  27. You also cannot connect an ARCnet card to any kind of Ethernet card and
  28. expect it to work.
  29. There are two "types" of ARCnet - STAR topology and BUS topology. This
  30. refers to how the cards are meant to be wired together. According to most
  31. available documentation, you can only connect STAR cards to STAR cards and
  32. BUS cards to BUS cards. That makes sense, right? Well, it's not quite
  33. true; see below under "Cabling."
  34. Once you get past these little stumbling blocks, ARCnet is actually quite a
  35. well-designed standard. It uses something called "modified token passing"
  36. which makes it completely incompatible with so-called "Token Ring" cards,
  37. but which makes transfers much more reliable than Ethernet does. In fact,
  38. ARCnet will guarantee that a packet arrives safely at the destination, and
  39. even if it can't possibly be delivered properly (ie. because of a cable
  40. break, or because the destination computer does not exist) it will at least
  41. tell the sender about it.
  42. Because of the carefully defined action of the "token", it will always make
  43. a pass around the "ring" within a maximum length of time. This makes it
  44. useful for realtime networks.
  45. In addition, all known ARCnet cards have an (almost) identical programming
  46. interface. This means that with one ARCnet driver you can support any
  47. card, whereas with Ethernet each manufacturer uses what is sometimes a
  48. completely different programming interface, leading to a lot of different,
  49. sometimes very similar, Ethernet drivers. Of course, always using the same
  50. programming interface also means that when high-performance hardware
  51. facilities like PCI bus mastering DMA appear, it's hard to take advantage of
  52. them. Let's not go into that.
  53. One thing that makes ARCnet cards difficult to program for, however, is the
  54. limit on their packet sizes; standard ARCnet can only send packets that are
  55. up to 508 bytes in length. This is smaller than the Internet "bare minimum"
  56. of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
  57. level of encapsulation is defined by RFC1201, which I call "packet
  58. splitting," that allows "virtual packets" to grow as large as 64K each,
  59. although they are generally kept down to the Ethernet-style 1500 bytes.
  60. For more information on the advantages and disadvantages (mostly the
  61. advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

  69. - Avery Pennraun <apenwarr@worldvisions.ca>
  70. - Stephen A. Wood <saw@hallc1.cebaf.gov>
  71. - John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
  72. - Joachim Koenig <jojo@repas.de>
  73. and Avery touched it up a bit, at Vojtech's request.
  74. ARCnet (the classic 2.5 Mbps version) can be connected by two different
  75. types of cabling: coax and twisted pair. The other ARCnet-type networks
  76. (100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
  77. cabling (Type1, Fiber, C1, C4, C5).
  78. For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
  79. also work fine, because ARCnet is a very stable network. I personally use 75
  80. Ohm TV antenna cable.
  81. Cards for coax cabling are shipped in two different variants: for BUS and
  82. STAR network topologies. They are mostly the same. The only difference
  83. lies in the hybrid chip installed. BUS cards use high impedance output,
  84. while STAR use low impedance. Low impedance card (STAR) is electrically
  85. equal to a high impedance one with a terminator installed.
  86. Usually, the ARCnet networks are built up from STAR cards and hubs. There
  87. are two types of hubs - active and passive. Passive hubs are small boxes
  88. with four BNC connectors containing four 47 Ohm resistors::
  89. | | wires
  90. R + junction
  91. -R-+-R- R 47 Ohm resistors
  92. R
  93. |
  94. The shielding is connected together. Active hubs are much more complicated;
  95. they are powered and contain electronics to amplify the signal and send it
  96. to other segments of the net. They usually have eight connectors. Active
  97. hubs come in two variants - dumb and smart. The dumb variant just
  98. amplifies, but the smart one decodes to digital and encodes back all packets
  99. coming through. This is much better if you have several hubs in the net,
  100. since many dumb active hubs may worsen the signal quality.
  101. And now to the cabling. What you can connect together:
  102. 1. A card to a card. This is the simplest way of creating a 2-computer
  103. network.
  104. 2. A card to a passive hub. Remember that all unused connectors on the hub
  105. must be properly terminated with 93 Ohm (or something else if you don't
  106. have the right ones) terminators.
  107. (Avery's note: oops, I didn't know that. Mine (TV cable) works
  108. anyway, though.)
  109. 3. A card to an active hub. Here is no need to terminate the unused
  110. connectors except some kind of aesthetic feeling. But, there may not be
  111. more than eleven active hubs between any two computers. That of course
  112. doesn't limit the number of active hubs on the network.
  113. 4. An active hub to another.
  114. 5. An active hub to passive hub.
  115. Remember that you cannot connect two passive hubs together. The power loss
  116. implied by such a connection is too high for the net to operate reliably.
  117. An example of a typical ARCnet network::
  118. R S - STAR type card
  119. S------H--------A-------S R - Terminator
  120. | | H - Hub
  121. | | A - Active hub
  122. | S----H----S
  123. S |
  124. |
  125. S
  126. The BUS topology is very similar to the one used by Ethernet. The only
  127. difference is in cable and terminators: they should be 93 Ohm. Ethernet
  128. uses 50 Ohm impedance. You use T connectors to put the computers on a single
  129. line of cable, the bus. You have to put terminators at both ends of the
  130. cable. A typical BUS ARCnet network looks like::
  131. RT----T------T------T------T------TR
  132. B B B B B B
  133. B - BUS type card
  134. R - Terminator
  135. T - T connector
  136. But that is not all! The two types can be connected together. According to
  137. the official documentation the only way of connecting them is using an active
  138. hub::
  139. A------T------T------TR
  140. | B B B
  141. S---H---S
  142. |
  143. S
  144. The official docs also state that you can use STAR cards at the ends of
  145. BUS network in place of a BUS card and a terminator::
  146. S------T------T------S
  147. B B
  148. But, according to my own experiments, you can simply hang a BUS type card
  149. anywhere in middle of a cable in a STAR topology network. And more - you
  150. can use the bus card in place of any star card if you use a terminator. Then
  151. you can build very complicated networks fulfilling all your needs! An
  152. example::
  153. S
  154. |
  155. RT------T-------T------H------S
  156. B B B |
  157. | R
  158. S------A------T-------T-------A-------H------TR
  159. | B B | | B
  160. | S BT |
  161. | | | S----A-----S
  162. S------H---A----S | |
  163. | | S------T----H---S |
  164. S S B R S
  165. A basically different cabling scheme is used with Twisted Pair cabling. Each
  166. of the TP cards has two RJ (phone-cord style) connectors. The cards are
  167. then daisy-chained together using a cable connecting every two neighboring
  168. cards. The ends are terminated with RJ 93 Ohm terminators which plug into
  169. the empty connectors of cards on the ends of the chain. An example::
  170. ___________ ___________
  171. _R_|_ _|_|_ _|_R_
  172. | | | | | |
  173. |Card | |Card | |Card |
  174. |_____| |_____| |_____|
  175. There are also hubs for the TP topology. There is nothing difficult
  176. involved in using them; you just connect a TP chain to a hub on any end or
  177. even at both. This way you can create almost any network configuration.
  178. The maximum of 11 hubs between any two computers on the net applies here as
  179. well. An example::
  180. RP-------P--------P--------H-----P------P-----PR
  181. |
  182. RP-----H--------P--------H-----P------PR
  183. | |
  184. PR PR
  185. R - RJ Terminator
  186. P - TP Card
  187. H - TP Hub
  188. Like any network, ARCnet has a limited cable length. These are the maximum
  189. cable lengths between two active ends (an active end being an active hub or
  190. a STAR card).
  191. ========== ======= ===========
  192. RG-62 93 Ohm up to 650 m
  193. RG-59/U 75 Ohm up to 457 m
  194. RG-11/U 75 Ohm up to 533 m
  195. IBM Type 1 150 Ohm up to 200 m
  196. IBM Type 3 100 Ohm up to 100 m
  197. ========== ======= ===========
  198. The maximum length of all cables connected to a passive hub is limited to 65
  199. meters for RG-62 cabling; less for others. You can see that using passive
  200. hubs in a large network is a bad idea. The maximum length of a single "BUS
  201. Trunk" is about 300 meters for RG-62. The maximum distance between the two
  202. most distant points of the net is limited to 3000 meters. The maximum length
  203. of a TP cable between two cards/hubs is 650 meters.
  204. Setting the Jumpers
  205. ===================
  206. All ARCnet cards should have a total of four or five different settings:
  207. - the I/O address: this is the "port" your ARCnet card is on. Probed
  208. values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
  209. your card has additional ones, which is possible, please tell me.) This
  210. should not be the same as any other device on your system. According to
  211. a doc I got from Novell, MS Windows prefers values of 0x300 or more,
  212. eating net connections on my system (at least) otherwise. My guess is
  213. this may be because, if your card is at 0x2E0, probing for a serial port
  214. at 0x2E8 will reset the card and probably mess things up royally.
  215. - Avery's favourite: 0x300.
  216. - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
  217. on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
  218. Make sure this is different from any other card on your system. Note
  219. that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
  220. "cat /proc/interrupts" for a somewhat complete list of which ones are in
  221. use at any given time. Here is a list of common usages from Vojtech
  222. Pavlik <vojtech@suse.cz>:
  223. ("Not on bus" means there is no way for a card to generate this
  224. interrupt)
  225. ====== =========================================================
  226. IRQ 0 Timer 0 (Not on bus)
  227. IRQ 1 Keyboard (Not on bus)
  228. IRQ 2 IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
  229. IRQ 3 COM2
  230. IRQ 4 COM1
  231. IRQ 5 FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
  232. IRQ 6 Floppy disk controller
  233. IRQ 7 FREE (LPT1 if you don't use the polling driver; PLIP)
  234. IRQ 8 Realtime Clock Interrupt (Not on bus)
  235. IRQ 9 FREE (VGA vertical sync interrupt if enabled)
  236. IRQ 10 FREE
  237. IRQ 11 FREE
  238. IRQ 12 FREE
  239. IRQ 13 Numeric Coprocessor (Not on bus)
  240. IRQ 14 Fixed Disk Controller
  241. IRQ 15 FREE (Fixed Disk Controller 2 if you have it)
  242. ====== =========================================================
  243. .. note::
  244. IRQ 9 is used on some video cards for the "vertical retrace"
  245. interrupt. This interrupt would have been handy for things like
  246. video games, as it occurs exactly once per screen refresh, but
  247. unfortunately IBM cancelled this feature starting with the original
  248. VGA and thus many VGA/SVGA cards do not support it. For this
  249. reason, no modern software uses this interrupt and it can almost
  250. always be safely disabled, if your video card supports it at all.
  251. If your card for some reason CANNOT disable this IRQ (usually there
  252. is a jumper), one solution would be to clip the printed circuit
  253. contact on the board: it's the fourth contact from the left on the
  254. back side. I take no responsibility if you try this.
  255. - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
  256. - the memory address: Unlike most cards, ARCnets use "shared memory" for
  257. copying buffers around. Make SURE it doesn't conflict with any other
  258. used memory in your system!
  259. ::
  260. A0000 - VGA graphics memory (ok if you don't have VGA)
  261. B0000 - Monochrome text mode
  262. C0000 \ One of these is your VGA BIOS - usually C0000.
  263. E0000 /
  264. F0000 - System BIOS
  265. Anything less than 0xA0000 is, well, a BAD idea since it isn't above
  266. 640k.
  267. - Avery's favourite: 0xD0000
  268. - the station address: Every ARCnet card has its own "unique" network
  269. address from 0 to 255. Unlike Ethernet, you can set this address
  270. yourself with a jumper or switch (or on some cards, with special
  271. software). Since it's only 8 bits, you can only have 254 ARCnet cards
  272. on a network. DON'T use 0 or 255, since these are reserved (although
  273. neat stuff will probably happen if you DO use them). By the way, if you
  274. haven't already guessed, don't set this the same as any other ARCnet on
  275. your network!
  276. - Avery's favourite: 3 and 4. Not that it matters.
  277. - There may be ETS1 and ETS2 settings. These may or may not make a
  278. difference on your card (many manuals call them "reserved"), but are
  279. used to change the delays used when powering up a computer on the
  280. network. This is only necessary when wiring VERY long range ARCnet
  281. networks, on the order of 4km or so; in any case, the only real
  282. requirement here is that all cards on the network with ETS1 and ETS2
  283. jumpers have them in the same position. Chris Hindy <chrish@io.org>
  284. sent in a chart with actual values for this:
  285. ======= ======= =============== ====================
  286. ET1 ET2 Response Time Reconfiguration Time
  287. ======= ======= =============== ====================
  288. open open 74.7us 840us
  289. open closed 283.4us 1680us
  290. closed open 561.8us 1680us
  291. closed closed 1118.6us 1680us
  292. ======= ======= =============== ====================
  293. Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
  294. network.
  295. Also, on many cards (not mine, though) there are red and green LED's.
  296. Vojtech Pavlik <vojtech@suse.cz> tells me this is what they mean:
  297. =============== =============== =====================================
  298. GREEN RED Status
  299. =============== =============== =====================================
  300. OFF OFF Power off
  301. OFF Short flashes Cabling problems (broken cable or not
  302. terminated)
  303. OFF (short) ON Card init
  304. ON ON Normal state - everything OK, nothing
  305. happens
  306. ON Long flashes Data transfer
  307. ON OFF Never happens (maybe when wrong ID)
  308. =============== =============== =====================================
  309. The following is all the specific information people have sent me about
  310. their own particular ARCnet cards. It is officially a mess, and contains
  311. huge amounts of duplicated information. I have no time to fix it. If you
  312. want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
  313. The model # is listed right above specifics for that card, so you should be
  314. able to use your text viewer's "search" function to find the entry you want.
  315. If you don't KNOW what kind of card you have, try looking through the
  316. various diagrams to see if you can tell.
  317. If your model isn't listed and/or has different settings, PLEASE PLEASE
  318. tell me. I had to figure mine out without the manual, and it WASN'T FUN!
  319. Even if your ARCnet model isn't listed, but has the same jumpers as another
  320. model that is, please e-mail me to say so.

  363. closed: star - open: bus
  364. On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI

  450. The PC130E is an enhanced version of the PC130 board, is equipped with a
  451. standard BNC female connector for connection to RG-62/U coax cable.
  452. Since this board is designed both for point-to-point connection in star
  453. networks and for connection to bus networks, it is downwardly compatible
  454. with all the other standard boards designed for coax networks (that is,
  455. the PC120, PC110 and PC100 star topology boards and the PC220, PC210 and
  456. PC200 bus topology boards).
  457. The PC270E is an enhanced version of the PC260 board, is equipped with two
  458. modular RJ11-type jacks for connection to twisted pair wiring.
  459. It can be used in a star or a daisy-chained network.

  501. Setting the Node ID
  502. ^^^^^^^^^^^^^^^^^^^
  503. The eight switches in group S2 are used to set the node ID.
  504. These switches work in a way similar to the PC100-series cards; see that
  505. entry for more information.
  506. Setting the I/O Base Address
  507. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  508. The first three switches in switch group S1 are used to select one
  509. of eight possible I/O Base addresses using the following table::
  510. Switch | Hex I/O
  511. 1 2 3 | Address
  512. -------|--------
  513. 0 0 0 | 260
  514. 0 0 1 | 290

  519. 1 1 0 | 380
  520. 1 1 1 | 3E0
  521. Setting the Base Memory (RAM) buffer Address
  522. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  523. The memory buffer requires 2K of a 16K block of RAM. The base of this
  524. 16K block can be located in any of eight positions.
  525. Switches 4-6 of switch group S1 select the Base of the 16K block.
  526. Within that 16K address space, the buffer may be assigned any one of four
  527. positions, determined by the offset, switches 7 and 8 of group S1.

  571. *) To enable the 8K Boot PROM install the jumper ROM.
  572. The default is jumper ROM not installed.
  573. Setting the Timeouts and Interrupt
  574. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  575. The jumpers labeled EXT1 and EXT2 are used to determine the timeout
  576. parameters. These two jumpers are normally left open.
  577. To select a hardware interrupt level set one (only one!) of the jumpers
  578. IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
  579. Configuring the PC130E for Star or Bus Topology
  580. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  581. The single jumper labeled STAR is used to configure the PC130E board for
  582. star or bus topology.
  583. When the jumper is installed, the board may be used in a star network, when
  584. it is removed, the board can be used in a bus topology.
  585. Diagnostic LEDs
  586. ^^^^^^^^^^^^^^^
  587. Two diagnostic LEDs are visible on the rear bracket of the board.
  588. The green LED monitors the network activity: the red one shows the
  589. board activity::
  590. Green | Status Red | Status
  591. -------|------------------- ---------|-------------------
  592. on | normal activity flash/on | data transfer
  593. blink | reconfiguration off | no data transfer;
  594. off | defective board or | incorrect memory or
  595. | node ID is zero | I/O address
  596. PC500/PC550 Longboard (16-bit cards)
  597. ------------------------------------
  598. - from Juergen Seifert <seifert@htwm.de>
  599. .. note::
  600. There is another Version of the PC500 called Short Version, which
  601. is different in hard- and software! The most important differences
  602. are:
  603. - The long board has no Shared memory.
  604. - On the long board the selection of the interrupt is done by binary
  605. coded switch, on the short board directly by jumper.
  606. [Avery's note: pay special attention to that: the long board HAS NO SHARED
  607. MEMORY. This means the current Linux-ARCnet driver can't use these cards.
  608. I have obtained a PC500Longboard and will be doing some experiments on it in
  609. the future, but don't hold your breath. Thanks again to Juergen Seifert for
  610. his advice about this!]
  611. This description has been written by Juergen Seifert <seifert@htwm.de>
  612. using information from the following Original SMC Manual
  613. "Configuration Guide for SMC ARCNET-PC500/PC550
  614. Series Network Controller Boards Pub. # 900.033 Rev. A
  615. November, 1989"
  616. ARCNET is a registered trademark of the Datapoint Corporation

  618. The PC500 is equipped with a standard BNC female connector for connection
  619. to RG-62/U coax cable.
  620. The board is designed both for point-to-point connection in star networks
  621. and for connection to bus networks.
  622. The PC550 is equipped with two modular RJ11-type jacks for connection
  623. to twisted pair wiring.
  624. It can be used in a star or a daisy-chained (BUS) network.

  666. Setting the Node ID
  667. ^^^^^^^^^^^^^^^^^^^
  668. The eight switches in group SW3 are used to set the node ID. Each node
  669. attached to the network must have an unique node ID which must be
  670. different from 0.
  671. Switch 1 serves as the least significant bit (LSB).
  672. The node ID is the sum of the values of all switches set to "1"
  673. These values are::
  674. Switch | Value
  675. -------|-------
  676. 1 | 1
  677. 2 | 2
  678. 3 | 4
  679. 4 | 8
  680. 5 | 16
  681. 6 | 32
  682. 7 | 64
  683. 8 | 128
  684. Some Examples::

  700. Setting the I/O Base Address
  701. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  702. The first six switches in switch group SW1 are used to select one
  703. of 32 possible I/O Base addresses using the following table::
  704. Switch | Hex I/O
  705. 6 5 4 3 2 1 | Address
  706. -------------|--------
  707. 0 1 0 0 0 0 | 200

  738. 1 1 1 1 1 1 | 3F0
  739. Setting the Interrupt
  740. ^^^^^^^^^^^^^^^^^^^^^
  741. Switches seven through ten of switch group SW1 are used to select the
  742. interrupt level. The interrupt level is binary coded, so selections
  743. from 0 to 15 would be possible, but only the following eight values will
  744. be supported: 3, 4, 5, 7, 9, 10, 11, 12.
  745. ::
  746. Switch | IRQ
  747. 10 9 8 7 |
  748. ---------|--------
  749. 0 0 1 1 | 3
  750. 0 1 0 0 | 4
  751. 0 1 0 1 | 5
  752. 0 1 1 1 | 7
  753. 1 0 0 1 | 9 (=2) (default)
  754. 1 0 1 0 | 10
  755. 1 0 1 1 | 11
  756. 1 1 0 0 | 12
  757. Setting the Timeouts
  758. ^^^^^^^^^^^^^^^^^^^^
  759. The two jumpers JP2 (1-4) are used to determine the timeout parameters.
  760. These two jumpers are normally left open.
  761. Refer to the COM9026 Data Sheet for alternate configurations.
  762. Configuring the PC500 for Star or Bus Topology
  763. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  764. The single jumper labeled JP6 is used to configure the PC500 board for
  765. star or bus topology.
  766. When the jumper is installed, the board may be used in a star network, when
  767. it is removed, the board can be used in a bus topology.
  768. Diagnostic LEDs
  769. ^^^^^^^^^^^^^^^
  770. Two diagnostic LEDs are visible on the rear bracket of the board.
  771. The green LED monitors the network activity: the red one shows the
  772. board activity::
  773. Green | Status Red | Status
  774. -------|------------------- ---------|-------------------
  775. on | normal activity flash/on | data transfer
  776. blink | reconfiguration off | no data transfer;
  777. off | defective board or | incorrect memory or
  778. | node ID is zero | I/O address
  779. PC710 (8-bit card)
  780. ------------------
  781. - from J.S. van Oosten <jvoosten@compiler.tdcnet.nl>
  782. Note: this data is gathered by experimenting and looking at info of other
  783. cards. However, I'm sure I got 99% of the settings right.
  784. The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
  785. LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing::
  786. _______________________________________

  803. |||||||||||||||||||||
  804. The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
  805. labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
  806. IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
  807. S1 and S2 perform the same function as on the PC270, only their numbers
  808. are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
  809. I know it works when connected to a PC110 type ARCnet board.

  813. LCS-8830(-T) (8 and 16-bit cards)
  814. ---------------------------------
  815. - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
  816. - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
  817. LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
  818. only (the JP0 jumper is hardwired), and BNC only.
  819. This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
  820. nowhere else, not even on the few Xeroxed sheets from the manual).

  910. PDI507 (8-bit card)
  911. --------------------
  912. - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
  913. - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
  914. are mostly the same as this. PDI508Plus cards appear to be mainly
  915. software-configured.
  916. Jumpers:
  917. There is a jumper array at the bottom of the card, near the edge
  918. connector. This array is labelled J1. They control the IRQs and
  919. something else. Put only one jumper on the IRQ pins.
  920. ETS1, ETS2 are for timing on very long distance networks. See the
  921. more general information near the top of this file.
  922. There is a J2 jumper on two pins. A jumper should be put on them,
  923. since it was already there when I got the card. I don't know what
  924. this jumper is for though.
  925. There is a two-jumper array for J3. I don't know what it is for,
  926. but there were already two jumpers on it when I got the card. It's
  927. a six pin grid in a two-by-three fashion. The jumpers were
  928. configured as follows::
  929. .-------.
  930. o | o o |
  931. :-------: ------> Accessible end of card with connectors
  932. o | o o | in this direction ------->
  933. `-------'
  934. Carl de Billy <CARL@carainfo.com> explains J3 and J4:

  946. - If using coax cable in a bus topology the J4 jumper must be removed;
  947. place it on one pin.
  948. - If using bus topology with twisted pair wiring move the J3
  949. jumpers so they connect the middle pin and the pins closest to the RJ11
  950. Connectors. Also the J4 jumper must be removed; place it on one pin of
  951. J4 jumper for storage.
  952. - If using star topology with twisted pair wiring move the J3
  953. jumpers so they connect the middle pin and the pins closest to the RJ11
  954. connectors.
  955. DIP Switches:
  956. The DIP switches accessible on the accessible end of the card while
  957. it is installed, is used to set the ARCnet address. There are 8
  958. switches. Use an address from 1 to 254
  959. ========== =========================
  960. Switch No. ARCnet address
  961. 12345678
  962. ========== =========================
  963. 00000000 FF (Don't use this!)
  964. 00000001 FE
  965. 00000010 FD
  966. ...
  967. 11111101 2
  968. 11111110 1
  969. 11111111 0 (Don't use this!)
  970. ========== =========================
  971. There is another array of eight DIP switches at the top of the
  972. card. There are five labelled MS0-MS4 which seem to control the
  973. memory address, and another three labelled IO0-IO2 which seem to
  974. control the base I/O address of the card.
  975. This was difficult to test by trial and error, and the I/O addresses
  976. are in a weird order. This was tested by setting the DIP switches,
  977. rebooting the computer, and attempting to load ARCETHER at various
  978. addresses (mostly between 0x200 and 0x400). The address that caused
  979. the red transmit LED to blink, is the one that I thought works.
  980. Also, the address 0x3D0 seem to have a special meaning, since the
  981. ARCETHER packet driver loaded fine, but without the red LED
  982. blinking. I don't know what 0x3D0 is for though. I recommend using
  983. an address of 0x300 since Windows may not like addresses below
  984. 0x300.
  985. ============= ===========
  986. IO Switch No. I/O address
  987. 210
  988. ============= ===========
  989. 111 0x260
  990. 110 0x290
  991. 101 0x2E0
  992. 100 0x2F0
  993. 011 0x300
  994. 010 0x350
  995. 001 0x380
  996. 000 0x3E0
  997. ============= ===========
  998. The memory switches set a reserved address space of 0x1000 bytes
  999. (0x100 segment units, or 4k). For example if I set an address of
  1000. 0xD000, it will use up addresses 0xD000 to 0xD100.
  1001. The memory switches were tested by booting using QEMM386 stealth,
  1002. and using LOADHI to see what address automatically became excluded
  1003. from the upper memory regions, and then attempting to load ARCETHER
  1004. using these addresses.
  1005. I recommend using an ARCnet memory address of 0xD000, and putting
  1006. the EMS page frame at 0xC000 while using QEMM stealth mode. That
  1007. way, you get contiguous high memory from 0xD100 almost all the way
  1008. the end of the megabyte.
  1009. Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
  1010. on my card. It could be malfunctioning on my card. Experiment with
  1011. it ON first, and if it doesn't work, set it to OFF. (It may be a
  1012. modifier for the 0x200 bit?)

  1097. Setting the Node ID
  1098. ^^^^^^^^^^^^^^^^^^^
  1099. The eight switches in SW2 are used to set the node ID. Each node attached
  1100. to the network must have an unique node ID which must be different from 0.
  1101. Switch 1 (ID0) serves as the least significant bit (LSB).
  1102. The node ID is the sum of the values of all switches set to "1"
  1103. These values are:
  1104. ======= ====== =====
  1105. Switch Label Value
  1106. ======= ====== =====
  1107. 1 ID0 1

  1132. Setting the I/O Base Address
  1133. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1134. The last three switches in switch block SW1 are used to select one
  1135. of eight possible I/O Base addresses using the following table::
  1136. Switch | Hex I/O
  1137. 6 7 8 | Address
  1138. ------------|--------
  1139. ON ON ON | 260
  1140. OFF ON ON | 290
  1141. ON OFF ON | 2E0 (Manufacturer's default)
  1142. OFF OFF ON | 2F0
  1143. ON ON OFF | 300
  1144. OFF ON OFF | 350
  1145. ON OFF OFF | 380
  1146. OFF OFF OFF | 3E0
  1147. Setting the Base Memory (RAM) buffer Address
  1148. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1149. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1150. located in any of eight positions. The address of the Boot Prom is
  1151. memory base + 8K or memory base + 0x2000.
  1152. Switches 1-5 of switch block SW1 select the Memory Base address.
  1153. ::
  1154. Switch | Hex RAM | Hex ROM
  1155. 1 2 3 4 5 | Address | Address *)
  1156. --------------------|---------|-----------
  1157. ON ON ON ON ON | C0000 | C2000
  1158. ON ON OFF ON ON | C4000 | C6000
  1159. ON ON ON OFF ON | CC000 | CE000
  1160. ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
  1161. ON ON ON ON OFF | D4000 | D6000
  1162. ON ON OFF ON OFF | D8000 | DA000
  1163. ON ON ON OFF OFF | DC000 | DE000
  1164. ON ON OFF OFF OFF | E0000 | E2000
  1165. *) To enable the Boot ROM install the jumper JP1
  1166. .. note::
  1167. Since the switches 1 and 2 are always set to ON it may be possible
  1168. that they can be used to add an offset of 2K, 4K or 6K to the base
  1169. address, but this feature is not documented in the manual and I
  1170. haven't tested it yet.
  1171. Setting the Interrupt Line
  1172. ^^^^^^^^^^^^^^^^^^^^^^^^^^
  1173. To select a hardware interrupt level install one (only one!) of the jumpers
  1174. JP2, JP3, JP4, JP5, JP6. JP2 is the default::
  1175. Jumper | IRQ
  1176. -------|-----
  1177. 2 | 2
  1178. 3 | 3
  1179. 4 | 4
  1180. 5 | 5
  1181. 6 | 7
  1182. Setting the Internal Terminator on CN120AB/TP/SBT
  1183. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1184. The jumper JP12 is used to enable the internal terminator::
  1185. -----
  1186. 0 | 0 |
  1187. ----- ON | | ON
  1188. | 0 | | 0 |
  1189. | | OFF ----- OFF
  1190. | 0 | 0
  1191. -----
  1192. Terminator Terminator
  1193. disabled enabled
  1194. Selecting the Connector Type on CN120ST/SBT
  1195. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  1205. Coaxial Cable Twisted Pair Cable
  1206. (Default)
  1207. Setting the Timeout Parameters
  1208. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1209. The jumpers labeled EXT1 and EXT2 are used to determine the timeout
  1210. parameters. These two jumpers are normally left open.

  1310. combinations are documented.
  1311. Setting the Base Memory (RAM) buffer Address
  1312. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1313. The switches 7-10 of switch block SW1 are used to select the Memory
  1314. Base address of the RAM (2K) and the PROM::
  1315. Switch | Hex RAM | Hex ROM
  1316. 7 8 9 10 | Address | Address

  1337. 10 | 5
  1338. 11 | 6
  1339. 12 | 7
  1340. 13 | 2 (=9) Default!
  1341. .. note::
  1342. - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
  1343. Controller
  1344. - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
  1345. Hard Disk, it may conflict with their controllers
  1346. Setting the Timeout Parameters
  1347. ------------------------------
  1348. The jumpers labeled JP1 and JP2 are used to determine the timeout
  1349. parameters. These two jumpers are normally left open.

  1394. It seems that the bits are considered in reverse order. Also, you must
  1395. observe that some of those addresses are unusual and I didn't probe them; I
  1396. used a memory dump in DOS to identify them. For the 00000 configuration and
  1397. some others that I didn't write here the card seems to conflict with the
  1398. video card (an S3 GENDAC). I leave the full decoding of those addresses to
  1399. you.

  1484. Setting the Node ID
  1485. ^^^^^^^^^^^^^^^^^^^
  1486. The eight switches in SW2 are used to set the node ID. Each node attached
  1487. to the network must have an unique node ID which must not be 0.
  1488. Switch 1 (ID0) serves as the least significant bit (LSB).
  1489. Setting one of the switches to OFF means "1", ON means "0".
  1490. The node ID is the sum of the values of all switches set to "1"
  1491. These values are::
  1492. Switch | Value
  1493. -------|-------
  1494. 1 | 1
  1495. 2 | 2
  1496. 3 | 4
  1497. 4 | 8
  1498. 5 | 16
  1499. 6 | 32
  1500. 7 | 64
  1501. 8 | 128
  1502. Don't set this to 0 or 255; these values are reserved.
  1503. Setting the I/O Base Address
  1504. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1505. The switches 1 to 6 of switch block SW1 are used to select one
  1506. of 32 possible I/O Base addresses using the following tables::
  1507. | Hex
  1508. Switch | Value
  1509. -------|-------
  1510. 1 | 200
  1511. 2 | 100
  1512. 3 | 80
  1513. 4 | 40
  1514. 5 | 20
  1515. 6 | 10
  1516. The I/O address is sum of all switches set to "1". Remember that
  1517. the I/O address space bellow 0x200 is RESERVED for mainboard, so
  1518. switch 1 should be ALWAYS SET TO OFF.
  1519. Setting the Base Memory (RAM) buffer Address
  1520. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1521. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1522. located in any of sixteen positions. However, the addresses below
  1523. A0000 are likely to cause system hang because there's main RAM.
  1524. Jumpers 7-10 of switch block SW1 select the Memory Base address::
  1525. Switch | Hex RAM
  1526. 7 8 9 10 | Address
  1527. ----------------|---------
  1528. OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
  1529. OFF OFF OFF ON | E0000
  1530. OFF OFF ON OFF | D0000
  1531. OFF OFF ON ON | C0000 (conflicts with video BIOS)
  1532. OFF ON OFF OFF | B0000 (conflicts with mono video)
  1533. OFF ON OFF ON | A0000 (conflicts with graphics)
  1534. Setting the Interrupt Line
  1535. ^^^^^^^^^^^^^^^^^^^^^^^^^^
  1536. Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
  1537. shorted, OFF means open::
  1538. Jumper | IRQ
  1539. 1 2 3 4 5 |
  1540. ----------------------------
  1541. ON OFF OFF OFF OFF | 7
  1542. OFF ON OFF OFF OFF | 5
  1543. OFF OFF ON OFF OFF | 4
  1544. OFF OFF OFF ON OFF | 3
  1545. OFF OFF OFF OFF ON | 2
  1546. Unknown jumpers & sockets
  1547. ^^^^^^^^^^^^^^^^^^^^^^^^^
  1548. I know nothing about these. I just guess that J16&J17 are timeout
  1549. jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
  1550. J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
  1551. guess the purpose.
  1552. Datapoint?
  1553. ==========
  1554. LAN-ARC-8, an 8-bit card
  1555. ------------------------
  1556. - from Vojtech Pavlik <vojtech@suse.cz>
  1557. This is another SMC 90C65-based ARCnet card. I couldn't identify the
  1558. manufacturer, but it might be DataPoint, because the card has the
  1559. original arcNet logo in its upper right corner.

  1627. OFF OFF OFF | 3E0
  1628. Setting the Base Memory (RAM) buffer Address
  1629. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  1630. The memory buffer (RAM) requires 2K. The base of this buffer can be
  1631. located in any of eight positions. The address of the Boot Prom is
  1632. memory base + 0x2000.
  1633. Jumpers 3-5 of switch block SW1 select the Memory Base address.
  1634. ::
  1635. Switch | Hex RAM | Hex ROM

  1646. *) To enable the Boot ROM set the switch 8 of switch block SW3 to position ON.
  1647. The switches 1 and 2 probably add 0x0800 and 0x1000 to RAM base address.
  1648. Setting the Interrupt Line
  1649. ^^^^^^^^^^^^^^^^^^^^^^^^^^
  1650. Switches 1-5 of the switch block SW3 control the IRQ level::

  1834. There is a DIP-switch with 8 switches, used to set the shared memory address
  1835. to be used. The first 6 switches set the address, the 7th doesn't have any
  1836. function, and the 8th switch is used to select "compatible" or "enhanced".
  1837. When I got my two cards, one of them had this switch set to "enhanced". That
  1838. card didn't work at all, it wasn't even recognized by the driver. The other
  1839. card had this switch set to "compatible" and it behaved absolutely normally. I
  1840. guess that the switch on one of the cards, must have been changed accidentally
  1841. when the card was taken out of its former host. The question remains
  1842. unanswered, what is the purpose of the "enhanced" position?
  1843. [Avery's note: "enhanced" probably either disables shared memory (use IO
  1844. ports instead) or disables IO ports (use memory addresses instead). This
  1845. varies by the type of card involved. I fail to see how either of these
  1846. enhance anything. Send me more detailed information about this mode, or
  1847. just use "compatible" mode instead.]

  1853. [Avery's note: these don't work with my driver for some reason. These cards
  1854. SEEM to have settings similar to the PDI508Plus, which is
  1855. software-configured and doesn't work with my driver either. The "Waterloo
  1856. chip" is a boot PROM, probably designed specifically for the University of
  1857. Waterloo. If you have any further information about this card, please
  1858. e-mail me.]
  1859. The probe has not been able to detect the card on any of the J2 settings,
  1860. and I tried them again with the "Waterloo" chip removed.

  1982. Setting the Node ID
  1983. ^^^^^^^^^^^^^^^^^^^
  1984. The eight switches in group SW1 are used to set the node ID.
  1985. Each node attached to the network must have an unique node ID which
  1986. must be different from 0.
  1987. Switch 8 serves as the least significant bit (LSB).
  1988. The node ID is the sum of the values of all switches set to "1"
  1989. These values are::
  1990. Switch | Value
  1991. -------|-------
  1992. 8 | 1
  1993. 7 | 2
  1994. 6 | 4

  2016. Setting the I/O Base Address
  2017. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2018. The first three switches in switch group SW2 are used to select one
  2019. of eight possible I/O Base addresses using the following table::
  2020. Switch | Hex I/O
  2021. 1 2 3 | Address
  2022. ------------|--------
  2023. ON ON ON | 260
  2024. ON ON OFF | 290
  2025. ON OFF ON | 2E0 (Manufacturer's default)
  2026. ON OFF OFF | 2F0
  2027. OFF ON ON | 300
  2028. OFF ON OFF | 350
  2029. OFF OFF ON | 380
  2030. OFF OFF OFF | 3E0
  2031. Setting the Base Memory (RAM) buffer Address
  2032. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2033. The memory buffer requires 2K of a 16K block of RAM. The base of this
  2034. 16K block can be located in any of eight positions.
  2035. Switches 4-6 of switch group SW2 select the Base of the 16K block.
  2036. Within that 16K address space, the buffer may be assigned any one of four
  2037. positions, determined by the offset, switches 7 and 8 of group SW2.

  2087. Setting the Timeouts
  2088. ^^^^^^^^^^^^^^^^^^^^
  2089. The two jumpers labeled ET1 and ET2 are used to determine the timeout

  2101. -------------
  2102. The manual of my 8-Bit NONAME ARCnet Card contains another description
  2103. of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
  2104. because there are missing two pages in the manual booklet. (The table
  2105. of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
  2106. the booklet there is a different way of counting ... 2-9, 2-10, A-1,
  2107. (empty page), 3-1, ..., 3-18, A-1 (again), A-2)
  2108. Also the picture of the board layout is not as good as the picture of
  2109. 8-Bit card, because there isn't any letter like "SW1" written to the
  2110. picture.

  2246. 8-bit cards ("Made in Taiwan R.O.C.")
  2247. -------------------------------------
  2248. - from Vojtech Pavlik <vojtech@suse.cz>
  2249. I have named this ARCnet card "NONAME", since I got only the card with
  2250. no manual at all and the only text identifying the manufacturer is
  2251. "MADE IN TAIWAN R.O.C" printed on the card.

  2278. 90C65 ARCNET Chip
  2279. SW1 1-5: Base Memory Address Select
  2280. 6-8: Base I/O Address Select
  2281. SW2 1-8: Node ID Select (ID0-ID7)
  2282. SW3 1-5: IRQ Select
  2283. 6-7: Extra Timeout
  2284. 8 : ROM Enable
  2285. JP1 Led connector
  2286. BNC Coax connector
  2287. Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
  2288. switches.
  2289. Setting the jumpers to ON means connecting the upper two pins, off the bottom
  2290. two - or - in case of IRQ setting, connecting none of them at all.
  2291. Setting the Node ID
  2292. ^^^^^^^^^^^^^^^^^^^
  2293. The eight switches in SW2 are used to set the node ID. Each node attached
  2294. to the network must have an unique node ID which must not be 0.
  2295. Switch 1 (ID0) serves as the least significant bit (LSB).
  2296. Setting one of the switches to Off means "1", On means "0".
  2297. The node ID is the sum of the values of all switches set to "1"
  2298. These values are::
  2299. Switch | Label | Value
  2300. -------|-------|-------
  2301. 1 | ID0 | 1
  2302. 2 | ID1 | 2
  2303. 3 | ID2 | 4
  2304. 4 | ID3 | 8

  2306. 6 | ID5 | 32
  2307. 7 | ID6 | 64
  2308. 8 | ID7 | 128
  2309. Some Examples::
  2310. Switch | Hex | Decimal
  2311. 8 7 6 5 4 3 2 1 | Node ID | Node ID

  2325. Setting the I/O Base Address
  2326. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2327. The last three switches in switch block SW1 are used to select one
  2328. of eight possible I/O Base addresses using the following table::
  2329. Switch | Hex I/O
  2330. 6 7 8 | Address
  2331. ------------|--------
  2332. ON ON ON | 260
  2333. OFF ON ON | 290
  2334. ON OFF ON | 2E0 (Manufacturer's default)
  2335. OFF OFF ON | 2F0
  2336. ON ON OFF | 300
  2337. OFF ON OFF | 350
  2338. ON OFF OFF | 380
  2339. OFF OFF OFF | 3E0
  2340. Setting the Base Memory (RAM) buffer Address
  2341. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2342. The memory buffer (RAM) requires 2K. The base of this buffer can be
  2343. located in any of eight positions. The address of the Boot Prom is
  2344. memory base + 0x2000.
  2345. Jumpers 3-5 of jumper block SW1 select the Memory Base address.
  2346. ::
  2347. Switch | Hex RAM | Hex ROM
  2348. 1 2 3 4 5 | Address | Address *)
  2349. --------------------|---------|-----------
  2350. ON ON ON ON ON | C0000 | C2000
  2351. ON ON OFF ON ON | C4000 | C6000
  2352. ON ON ON OFF ON | CC000 | CE000
  2353. ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
  2354. ON ON ON ON OFF | D4000 | D6000
  2355. ON ON OFF ON OFF | D8000 | DA000
  2356. ON ON ON OFF OFF | DC000 | DE000
  2357. ON ON OFF OFF OFF | E0000 | E2000
  2358. *) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
  2359. The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
  2360. Setting the Interrupt Line
  2361. ^^^^^^^^^^^^^^^^^^^^^^^^^^
  2362. Jumpers 1-5 of the jumper block SW3 control the IRQ level::
  2363. Jumper | IRQ
  2364. 1 2 3 4 5 |
  2365. ----------------------------
  2366. ON OFF OFF OFF OFF | 2
  2367. OFF ON OFF OFF OFF | 3
  2368. OFF OFF ON OFF OFF | 4
  2369. OFF OFF OFF ON OFF | 5
  2370. OFF OFF OFF OFF ON | 7
  2371. Setting the Timeout Parameters
  2372. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2373. The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
  2374. parameters. These two jumpers are normally left in the OFF position.

  2424. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2425. To select a hardware interrupt level set one (only one!) of the dip switches
  2426. up (on) SW1...(switches 1-5)
  2427. IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
  2428. The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
  2429. are used to determine the timeout parameters. These two dip switches
  2430. are normally left off (down).
  2431. To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
  2432. The default is jumper ROM not installed.
  2433. Setting the I/O Base Address
  2434. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  2435. The last three switches in switch group SW2 are used to select one
  2436. of eight possible I/O Base addresses using the following table::
  2437. Switch | Hex I/O
  2438. 4 5 6 | Address
  2439. -------|--------

  2467. Setting the Node ID
  2468. ^^^^^^^^^^^^^^^^^^^
  2469. The eight switches in group SW3 are used to set the node ID.
  2470. Each node attached to the network must have an unique node ID which
  2471. must be different from 0.
  2472. Switch 1 serves as the least significant bit (LSB).
  2473. switches in the DOWN position are OFF (0) and in the UP position are ON (1)
