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 which 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 which 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 1260-01S, 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 which are available for the 1260-01T.

Control Information for the 1260-60
The following information describes the control-register-to-relay-channel mapping for a 1260-60 Relay
Module. This information may be used to control a 1260-60 when using a 1260-01T in the register-based
mode of operation.
There are two types of relays which populate the 1260-60 module. The standard relays (channels 0 through
111), are each controlled by a single bit within an 8-bit Control Register. Each of these relays 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 1 closes the relay;
setting the bit to a 0 opens the relay.
The RF relays (channels 200, 201, and 202) are each controlled by 2 bits. Each of these relays is a latching
relay. One bit is pulsed to set the relay to the OPEN state, in which the COM output is connected to the
normally closed input. A different bit is pulsed to set the relay to the CLOSED state, where the COM output is
connected to the normally open input. An OPEN or CLOSE control bit must be set high for a minimum of
15 milliseconds before it is deasserted to ensure that the latching relay is actuated.
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
0 is 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.

INSTALLATION INSTRUCTION
Unpacking and
Inspection 1. Before unpacking the switching module, check the exterior
of the shipping carton for any signs of damage. All
irregularities should be noted on the shipping bill.
2. Remove the instrument from its carton, preserving the
factory packaging as much as possible.
3. Inspect the switching module for any defect or damage.
Notify the carrier immediately if any damage is apparent.
4. Have a qualified person check the instrument for safety
before use.
Reshipment
Instructions 1. Use the original packing if it is necessary to return the
switching module to Racal Instruments for calibration or
servicing. The original shipping carton and the
instrument's plastic foam will provide the necessary
support for safe reshipment.
2. If the original packing is unavailable, wrap the switching
module in plastic sheeting and use plastic spray foam to
surround and protect the instrument.

User Manual 1260-60A/B
Installation Instructions 2-2
1260-60 (A or B) 5=ON 6=ON
Note that incorrect setting of the ID byte DIP switches will cause
an incorrect module ID to be reported to the user in response to
a PDATAOUT command. All other module functionality is
unaffected by the setting of the ID byte switches.
Relay Bank
Configuration If two banks of DC relays are to be used, various internal
jumpers must be installed. Examples of four possible
configurations are shown in Figures 4-3 through 4-6. The card is
shipped from the factory without any jumpers installed.
To access the jumpers, remove the right side cover from the
module. The jumpers are located on the large PCB Assembly.
There are two banks of relays. Each bank is configured
independently, and the two configurations do not have to match.
The banks are designated Bank A and Bank B.
Sink/Source
Configuration
A sink driver connects its output to ground to energize a load; a
source connects its output to B+ to energize a load. Eight push-
on jumpers are to be installed as shown below:
Bank A Source Driver:W5
Bank A Sink Driver: W6
Bank B Source Driver:W11
Bank B Sink Driver: W12
Power - Bank A If an external supply is to be used, the jumpers at locations W3
and W4 are to be removed. If the VXI +5 V supply is to be used,
eight jumpers are to be installed at location W3 (1-2, 3-4, 5-6,
etc.). If the VXI +12 V supply is to be used, three jumpers are to
be installed at location W4 (1-2, 3-4, and 5-6). If the VXI +24 V
supply is to be used, the three jumpers are to be installed at
location W4 (11-12, 13-14, 15-16).
Power - Bank B If an external supply is to be used, the jumpers at locations W8
and W9 are to be removed. If the VXI +5 V supply is to be used,
eight jumpers are to be installed at location W8 (1-2, 3-4, 5-6,
etc.). If the VXI +12 V supply is to be used, three jumpers are to
be installed at location W9 (1-2, 3-4, and 5-6). If the VXI +24 V
supply is to be used, three jumpers are to be installed at location
W9 (11-12, 13-14, 15-16).

Module Specific Syntax 3-1
Chapter 3
MODULE SPECIFIC SYNTAX
1260-60A/B
Syntax The Module Specific Syntax for the 1260-6A,B module is as
follows:
<mod addr>.<bank no><relay no>
where <mod addr> is the address of the 1260-60A,B.
NOTE
The <mod addr> used here is NOT the VXIbus
defined logical address of the 1260 Series Master. It
is peculiar to the 1260 Series and describes the
switching module in relation to the 1260 Master. This
address corresponds to the binary value of the
switch setting of SW1 on the switching module PCB.
<bank no> is a reference to the bank of the relay to be switched.
It is a single digit number.
The <bank no> refers to the following relay banks:
0 1x12BankA
1 1x12BankB
2 1x2 Relays S1, S2, S3
<relay no> refers to the relay to be operated. This is a two-digit
number. For Bank A and Bank B, this value must be between 00
and 11. For relay S1 it is 00, for S2-01, and for S3-02. Note the
leading 0 for relays 00 through 09 is required.
Refer to Figures 4-1, 4-2, and Table 4-1 for banks, relay
numbers, and connector pins for the 1260-60A,B module.
If more than one connection is to be made or broken on the
1260-60A,B with contiguous relays, the following format is
supported:
<mod addr>.<bank no><relay no>-<bank no><relay no>
Multiple groups of relays can be specified on a single command
