DISCLAIMER
Buyer acknowledges and agrees that it is responsible for the operation of the goods purchased and
should ensure that they are used properly and in accordance with this document and any other
instructions provided by Seller. Astronics Test Systems products are not specifically designed,
manufactured or intended to be used as parts, assemblies or components in planning, construction,
maintenance or operation of a nuclear facility, or in life support or safety critical applications in
which the failure of the Astronics Test Systems product could create a situation where personal
injury or death could occur. Should Buyer purchase Astronics Test Systems product for such
unintended application, Buyer shall indemnify and hold Astronics Test Systems, its officers,
employees, subsidiaries, affiliates and distributors harmless against all claims arising out of a claim
for personal injury or death associated with such unintended use.

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 proper fuse is in place for the power source to operate.
2. 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 1260-30A
The following information describes the control-register-to-relay-channel mapping for a 1260-30A
Relay Module. This information may be used to control a 1260-30A 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 1 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 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:
