PROPRIETARY NOTICE
This document and the technical data herein disclosed, are proprietary to Racal Instruments, and shall not,
without express written permission of Racal Instruments, be used, in whole or in part to solicit quotations from
a competitive source or used for manufacture by anyone other than Racal Instruments. The information herein

purposes or for purposes of engineering evaluation and incorporation into technical specifications and other
documents which specify procurement of products from Racal Instruments.

FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to human life and safety, and is capable of inflicting
personal injury.
If this instrument is to be powered from the AC line (mains) through an autotransformer, ensure
the common connector is connected to the neutral (earth pole) of the power supply.
Before operating the unit, ensure the conductor (green wire) is connected to the ground (earth)
conductor of the power outlet. Do not use a two-conductor extension cord or a three-prong/two-
prong adapter. This will defeat the protective feature of the third conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with power
applied and protective covers removed. Read the procedures and heed warnings to avoid “live”
circuit points.
Before operating this instrument:
1. Ensure the instrument is configured to operate on the voltage at the power source. See
Installation Section.
2. Ensure the proper fuse is in place for the power source to operate.
3. Ensure all other devices connected to or in proximity to this instrument are properly grounded or
connected to the protective third-wire earth ground.
If the instrument:
- fails to operate satisfactorily
- shows visible damage
- has been stored under unfavorable conditions
- has sustained stress
Do not operate until performance is checked by qualified personnel.

NOTE FOR SYSTEMS WITH 1260-OPT 01T
The "Module-Specific Syntax" section of this manual shows the command syntax for the
1260-01S Smart Card. If you are using the newer 1260-01T Smart Card, the commands
will NOT work as shown.
Consult the 1260-01T Manual for a description of the commands that may be used with the
1260-01T Smart Card.
The channel numbers described in this manual are valid for the 1260-01T. The channel
numbers continue to be used for the 1260-01T.
The syntax of the commands that use channel numbers has changed for those cards
controlled by the 1260-01T.
The new syntax used to close a channel is:
CLOSE (@ <module address> (<channel>))
For example, with for a relay module whose <module address> is set to 7, closing
<channel> 0 is performed with the command:
CLOSE (@ 7 (0))
Using the older 1260-01 5, the command would be (as shown in this manual):
CLOSE 7.0
Many other command syntax differences exist. Please consult chapter 2 of the 1260-01T
manual for a description of the commands that are available for the 1260-01T.

Control Information for the 1260-93A
The following information describes the control-register-to-relay-channel mapping for a 1260-93A and Relay
Module. This information may be used to control a 1260-93A when using a 1260-01T in the register-based
mode of operation.
Each relay on this module is controlled by setting or clearing a single bit within a Control Register. Control
Registers on the module operate 8 channels simultaneously. There are eight control bits per Control
Register. Setting the bit to a I closes the relay; setting the bit to a 0 opens the relay.
The table below shows the mapping from logical channels to control bits. The logical channels are used when
operating the relay module in message-based mode. The control bits within the Control Registers are used to
operate the module in register-based mode.
Each Control Register is located 2 addresses from the previous Control Register. That is, each Control
Register is located at an odd address. This is shown in Table 2-2 of the 1260-01T manual. Control Register
0is located at the "Base A24 Address" for the module. Consult the "Register-Based Operation" Section of
Chapter 2 of the 1260-01T manual for a description of calculating control register addresses.

OVERVIEW
1260-93
100MHz
Multiplexer
Module
The 1260-93A/B provides eight or sixteen, respectively, 1x4
93Ωmultiplexers (refer to the Functional Diagram Figure 1-2).
Relays CH19, 29,...,159 provide for the connections between
the adjacent 1x4 groups under software control. Thus, the 1260-
93A/B modules can be configured as multiplexers up to 1x39 or
1x79 in size. The 100 MHz bandwidth is guaranteed for all
possible multiplexer sizes as long as only groups required for a
specific connector are connected

Coaxial cables have been tested to 1GHz, and are available as
an option. Each cable contains a coaxial pin at each end. The
cables are available in 2, 6, and 12 feet, and can be cut by
customers to any length. (Example: The 6-foot cable can be cut
to two 3-foot, or one 2-foot and one 4-foot cable.) Coaxial pins
(P/N 602220-900 suitable for RG316 coaxial cable may be
purchased separately. Coaxial pins (P/N 602220-901) suitable
for coaxial cable smaller than RG3 16 may also be purchased
separately (consult factory for details). The 1260-93A requires
40, and the 1260-93B requires 80. To crimp coaxial pins, use
crimp tool Hytool M10S-1 from Bumdy.
