	Cables reference guide

	1 July 1996 While every effort has been made to ensure the accuracy of the material, this is old information and no one is responible for any inadvertent errors. Introduction Only cables which are of current interest have been included, so the list of entries is not exhaustive. The contents have been sourced from previous guides, from technical publications, and, from in-house investigation. Where cable data is not easily resourced, the technical data is incomplete, but hopefully still of value. Please note that this publication is for guidance only and does not include full engineering specifications. *Cables Reference Guide - Contents by Alpha-numeric Order ( indicates addition since last guide) Introduction Content by cable group General Notes - Ordering Codes Speed and Distance Considerations Digital's Standard Synchronous Connector Synchronous Cables Summary BC06P SCSI Cable BC09D SCSI Cable BC09J SCSI Cable BC09K SCSI Cable BC09R EtherWORKS Router Adapter Cable BC09S EtherWORKS Router Adapter Cable BC09T EtherWORKS Router Adapter Cable BC09U Eicon PC RS232-C Modem Cable BC09V Eicon HSI V.24 Modem Cable BC09W Eicon HSI V.35 Modem Cable BC09X Eicon HSI X.21 Modem Cable BC12F DECbrouter 90 X.21 Adapter Cable BC12G DECbrouter 90 V.35 Adapter Cable BC12H DECbrouter 90 RS422 Adapter Cable BC12J DECbrouter 90 EIA 530A Adapter Cable BC12K DECbrouter 90 RS423 Adapter Cable BC12L DECbrouter 90 RS232 Adapter Cable BC12N MemoryChannel Cable BC13L Video Cable for Color Monitor BC13M Keyboard / Mouse Extender Cable BC16C / BC16D DEC423 "Harmonica" Cables BC16E DEC423 "Office" Cable BC16K Thinwire Patching Cable BC16M Thinwire Cable BC19B EIA-422 Adapter Cable BC19C X.21 Adapter Cable BC19D V.24 Adapter Cable BC19E EIA-423 Adapter Cable BC19F V.35 Adapter Cable BC19J SCSI Cable BC19L V.35 Communications Cable BC19M IBM PC Parallel Interface Cable BC19N EIA-232 "One-To-Four" Cable BC19S Cable for Color Monitor BC19Y EIA-422 Null Modem Cable BC21G BT Kilostream Cable BC21M DSSI Cable BC21Q DSSI Cable BC22D Terminal Cable BC22E Modem Cable BC22F Modem Cable BC22H Gender Changer Cable BC22R EIA-232 Null Modem (CTS/RTS) Cable BC22Q DSSI Cable BC22X X.21 Adapter Cable.

H8245-D STP High Performance Data Grade. Category 5. H8246-D STP High Performance Data Grade (teflon) General Notes Cable option numbers tend to be of the format: BCxxx-yy or BNxxx-zz where the "C" indicates that the suffix "yy" describes the length of the cable in feet, for example BC21M-09...is a BC21M cable 9 feet long, and the "N" means the length "zz" is described in meters. BN25B-30 is a BN25B cable 30 metres long. Some cable options are prefixed with an "E0" identifier, this simply indicates the European origin of the cable, for example E0-BCC05-50 is a 50 feet long BCC05 sourced in Europe. Other Cable Lengths Letters may be used for cable lengths, eg, A = 100, B = 200, C = 300, D = 400, E = 500, H = 700, L = 1000, for example -A5 = 150, -B5 = 250, -C0 = 300, -H5 = 750, -L0 = 1000, so....... BN25B-H5 is a 750m BN25B cable, and BC22D-B5 is 250 feet long BC22D. These letters may also be used to indicate decimals or feet and inches, thus BN19A-2E is a 2.5m BN19A, and BC26V-6D is a 6 feet 4 inches long BC26V.

These two standards are compatible with each other. The EIA-232-D/CCITT V.24/V.28 standard was originally designed to specify the connection between a local interface and a modem. It was not intended to be used for connecting to terminals over long distances. The maximum specified length is 50 feet (15m), and shielded cable must be used in order to meet the requirements of FCC and VDE Radio Frequency Interference (RFI) regulations. Although cable lengths of greater than 50 feet can be used with reasonable success, cable capacitance, noise, and ground potential difference restrict the line speed as the distances increase. As a consequence of this, the performance of long distance communications to a terminal using EIA-232 does not meet today's requirements for terminal wiring. DEC423 is a superset of the RS-423-A/CCITT V.10 standard. RS-423-A has a different grounding and signal return path arrangement from EIA-232-D, as well as using different line driver and receiver chips. DEC423 uses line driver and receiver chips which have better filtering and tighter level tolerances than those specified by RS-232-A. In addition, DEC423 devices include transient suppressors for electrical overstress (EOS) and electro-static discharge (ESD) protection. DEC423 devices may also be connected with unshielded cable. The features provided by DEC423 devices provide reliable data communication over increased distances, typically 1000 feet (300m). Table of Distances Between Devices Device Type Speed: 4.8 Kbaud 9.6 Kbaud 19.2 Kbaud 38.4 Kbaud< DEC423 device to: DEC423 device 3000 ft 3000 ft 1000 ft 280ft DEC423 to EIA-232-D 200 ft 200 ft 50 ft 50 ft DEC422 to DEC422 4000 ft 4000 ft 4000 ft 4000 ft DEC423 uses the RJ45 Modular Jack, or the Modified Modular Jack (MMJ) connector instead of the much larger D-type connector defined in RS-449. DEC423 is signal compatible with the EIA-232-D standard when used for data-leads-only interconnection, ie, interconnection between devices using the different standards is possible but the speed and distance restrictions of EIA-232-D will still apply. DEC423 should always be used be used in preference to EIA-232-D for direct terminal connection over extended distances. EIA-232-D terminals can be connected to DEC423 devices using either an H8571-x passive adapter, or a H3105-B active adapter. The H3105-B active terminal adapter is necessary when using an EIA-232-D terminal with a DEC423 interface if the longer cable lengths obtainable with DEC423 are required. There are two types of DEC423 cable available: the H8245/6 "Building" cable which is of twisted pair construction, and the H8240 "Office" or flat 6-core ribbon cable. BC16E cables are pre-terminated lengths of H8240 cable. The maximum length for DEC423 cabling has been given, for example, 1000 feet at 19,200 Baud, and within this, 50 feet is the usually recommended maximum length of "office" cabling, however 100 feet would probably give satisfactory results. DEC422 also incorporates EOS/ESD protection and RS-422 compatible drivers and receivers, thus DEC422 is ideal for use in high noise environments. DEC422, which uses differential line drivers supports cable lengths of up to 4000 feet (1200m) at all supported speeds.

Signal Levels used with EIA-232. (EIA-232 is an unbalanced system with a common return). For Data : An EIA-232 transmitter generates a voltage of between -5 and -25 volts for a MARK (logic 1), and between +5 and +25 volts for a SPACE (logic 0). An EIA-232 receiver recognizes voltages of above +3 volts as spaces, and voltages more negative than -3 volts as marks. For Control : Between -3 and -25 volts for a NEGATION, and between +3 and +25 volts for an ASSERTION. EIA-423 : EIA-423 is also an unbalanced system, but unlike EIA-232, separate return wires are used for both transmit and receive data. With a EIA-423 transmitter the voltage must be at least +4 volts for a space, and -4 volts for a mark. EIA-422 : EIA-422 uses two separate wires for each signal, and is a balanced system. A mark is differentiated from a space by the polarity of one wire with respect to the other rather than with respect to ground. Appendix C - Terminal Server Adapters H8584-AC MMJ adapter.

End Connectors 12-19118-00 One N type RG8.8A Plug Testing It is recommended that a custom made length of Thickwire cable should be tested prior to use using a TDM (Time Domain Reflectometer), this is particularly important for segments which are to be heavily loaded. 2. ThinWire Ethernet Cable Ready to use ThinWire cables with PVC jackets are available with part number BC16M-xx . ThinWire cables may be joined together using a Barrel Connector part number E0-H8224. A ThinWire segment must be properly terminated with 50 Ohm impedanance terminators. ThinWire Terminator part number is E0-H8225. To attach a station to ThinWire Ethernet a "T" Connector ThinWire part number E0-H8223 must be fixed directly to that station, and the lengths of cable, or length of cable plus terminator will be attached to the "T" connector. ThinWire Ethernet cable may be custom made using the following components: Cable H8243-A 1000 feet spool of ThinWire coaxial cable with PVC jacket. Or Cable H8244-A 1000 feet spool of ThinWire coaxial cable with TEFLON jacket. End connectors E0-H8222 one male pin BNC connector. Tools The H8242 Tool Kit contains the necessary strippers and crimp tool to attach the end connectors to the raw cable. Appendix G - "Confusable" Cable Summary Summary Part 1 Summary Part 2 Appendix H - Fibre Optics Notes The fibre optic cables supplied by Digital such as the BN24B, BN24D, or BN24E are for internal use ONLY because they do not have a weather proofed or amoured jacket. 90% of fibre cable applications require that the cable be run externally either in a duct or even directly buried in the ground. It is a specialist job to define the cable required, the possible maximum lengths and the termination for a particular site and a particular application, so an in depth site survey will be required. Customers who do not have access to the necessary skills should be directed to their local Digital office or their account manager to IBS (Intelligent Building Services) who can provide a total installed and tested solution. In general, the Digital recommendation for a new fibre optic installation is for 62.5/125 micron, dual window, graded-index profile, multimode glass-on-glass construction (EIA Class 1A). Digital is optimising its multimode fibre products for 62.5/125 fibre. Connectors Types of fibre-optic connectors in current use:- ST - Bayonet This type of connector has a "push-twist" fastening action. It virtually replaced the older SMA-type which has a screw-on fastening. The ST provides a higher reliability and a better connection than the SMA. ST - Push-pull The push-pull construction provides easy insertion and high repeatability. SC This connector is physically smaller than the ST-type, has rectangular cross-section, and has a push-pull fixing action. There is both a simplex and a duplex version. Digital is using SC connectors in certain products because of the smaller physical size and also industry demand. The SC connector is specified in TIA/EIA 568-A. The duplex SC socket is considerably smaller than the widely used MIC socket. MIC The FDDI MIC (Media Interface Connector) is a duplex connector. The MIC is keyed, and is field programmable for the appropriate type of FDDI connection. FC/PC Digital chose the FC/PC connector for SM (Single Mode) fibre applications. One of the key selection factors was that FC-PC is physically different to the ST and thus customers could not inadvertently plug SM into MM (Multi Mode) sockets. However the newest physical media dependant options (PMDs), for example the DEFXS-BA, use ST connectors for SMF. Additional Note For FDDI FDDI modules which utilise Multimode Fibre (MMF) use both pairs of ST or SC connectors and also Media Interface Connectors (MIC). Modules utilizing Single Mode Fibre (SMF) use FC-PC connectors. Conductors MMF modules use 62.5/125 micron fibre. SMF modules use 8-10/125 micron fibre. The maximum possible cable length between nodes for MMF is 2 km. The maximum possible cable length between nodes for SMF is 40 km.
