Introduction
This guide has been produced by the Digital UK pre-sales Technical Support Group for use by Digital and its partners.
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.

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.

TLZ07 to the 68-way SCSI connector on the AlphaStation 500. The
68-way connector would be connected to the AlphaStation and would
terminate the high-byte; the 50-way connector would be joined
to the high density 50-way end of a cable such as the BN23G, and
the other 50-way low-density end of the BN23G would connect to
the TLZ07 tape drive.
Note that this BN36A-0B adapter is not needed when connecting
devices designed for use with the newest AlphaStations, as these
devices, such as the appropriate TLZ09 option have a built-in
adapter.

H8571-J
Since 1985, the Electrical Industries Association (EIA), decided
to replace the 'RS-' identifier with EIA', therefore RS-232-C
has been replaced by EIA-232-D. These two standards are compatible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
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.
where
DTE = Data Terminal Equipment (terminal or computer system), and
DCE = Data Communications Equipment (typically a modem).
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.
H8584-AC
MMJ adapter. A small adapter which plugs directly in to the 8-way

Tools
The H8242 Tool Kit contains the necessary strippers and crimp
tool to attach the end connectors to the raw cable.
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

the other to an " extender" cable, which in ptions (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.

LD = Low Density, or Centronics type connector. HD=
High Density, or Honda connector. VHD = Very High Density
(0.8 mm pitch)
Notes.
In general, all SCSI cables with a "BC" designation
are not wired to Fast SCSI specifications, whereas virtually all
cables made with a "BN" designation are wired to Fast
SCSI specifications, i.e.they have the correct impedance and internal
wiring which is suitable for use with the demanding Fast SCSI.
SCSI Terminators
H8574-A Single-ended, 8-bit SCSI bus Terminator with 50-pin,
male, low-density connector.
Example usage: attached to a BN21V-02 adapter cable to terminate
a single-ended SCSI bus at an end position controller, this would
facilitate the removal of that controller without interrupting
the bus.
12-29635-01 Single-ended, 8-bit SCSI bus Terminator with
68-pin, female, high-density connector.
Example usage: supplied with early workstations and InfoServer
150 for bus termination.
H879 -AA FWD (Fast Wide Differential) SCSI bus Terminator
with 68-pin, high-density, male connector.
Example usage: attached to an H885 -AA Tri-link Connector Block
to terminate a FWD SCSI at an end position controller, this would
facilitate removal of that controller without interrupting the
bus.
12-37004-04
50-pin, active single-ended terminator.
SCSI Connector Block
H885 -AA FWD SCSI Tri-link Connector Block with three 68-pin,
high-density connectors, one one side one male, on the other side
two female. A typical configuration would be:
DSSI Terminator
12-31281-01 DSSI bus Terminator with 50-pin, female MR
type connector. Typical usage: with a 12-39921-02 DSSI Tri-link
Adapter attached to a DSSI controller/adapter to facilitate the
removal of that adapter without interrupting the DSSI bus.
DSSI Connector Block
12-39921-02 DSSI Tri-link Connector Block which is supplied
attached to the DSSI port of DSSI controllers/adapters such as
the HSD05, HSD10, HSD30, HS1CP. The adapter presents two 50-pin,
male, MR connectors, to which would be attached a DSSI cable and
a 12-31281-01 DSSI terminator, or two DSSI cables.
