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 1260-12
The following information describes the control-register-to-relay-channel mapping for a 1260-12
Relay Module. This information may be used to control a 1260-12 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.

INSTALLATION INSTRUCTIONS
Unpacking and
Inspection 1. Remove the 1260-12 module and inspect it for damage. If any
damage is apparent, inform the carrier immediately. Retain
shipping carton and packing material for the carrier’s
inspection.
2. Verify that the pieces in the package you received contain the
correct 1260-12 module option and the 1260-12 Users Manual.
Notify EADS North America Defense Test and Services, Inc. if
the module appears damaged in any way. Do not attempt to
install a damaged module into a VXI chassis.
3. The 1260-12 module is shipped in an anti-static bag to prevent
electrostatic damage to the module. Do not remove the module
from the anti-static bag unless it is in a static-controlled area.

Reshipment
Instructions 1. Use the original packing when returning the switching module
to EADS North America Defense Test and Services, Inc. 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 material is unavailable, wrap the
switching module in an ESD Shielding bag and use plastic
spray foam to surround and protect the instrument.
3. Reship in either the original or a new shipping carton.
Option 01
Installation Installation of the Option 01 into the 1260-12 is described in the
Installation section of the 1260 Series VXI Switching Cards
Manual.
Module
Installation Installation of the 1260-12 Switching Module into a VXI
mainframe, including the setting of DIP switches, is described in
the Installation section of the 1260 Series VXI Switching Cards
Manual. The ID byte DIP switches, SW1-5 and SW1-6, should
both be set to OFF.

1260-12 User Manual
EADS North America Defense Module Specific Syntax 3-1
Test and Services, Inc. ©1993
Chapter 3
MODULE SPECIFIC SYNTAX
General The Module Specific Syntax for the 1260-12 is required in the use
of the OPEN and CLOSE commands. It will also appear in data
output by the Master in response to the PDATAOUT and
PSETUP commands.
NOTE:
The 1260-12 Relay Actuator Module is supported by Option
01 Operating Systems at Revision levels 2.1 and above.
Syntax The Module Specific Syntax for the 1260-12 Relay Actuator
module is as follows:
<module address>.<channel>
where <module address> is the address.
<channel> is the reference number of the relay to be
closed, value 0 - 19.
NOTE:
The <module address> used here is not the VXIbus defined
logical address of the 1260 Master. It is peculiar to the 1260
Series and describes the switching module in relation to the
Master. This address corresponds to the binary value of the
switch setting of SW1 on the switching module PCB.
Each <channel> is a double-pole, double-throw relay with two
normally open and two normally closed connections. The
connections are between the Common and the Open pins if the
<channel> is OPEN, and between the Common and the Closed
pins if the <channel> is CLOSED. The pin connections made by
each CLOSE <card address>.<channel> command are given in
Figure 3-2.

Test and Services, Inc. ©1993
Figure 3-1, Relay Diagram
PSETUP
Command
The PSETUP command causes the specified module setup to be
displayed as a response. The syntax used is:
PSETUP <module address>[;<module address>]
[;<module address>]
where <module address> is the switch card address.
The responses to the PSETUP command for the 1260-12 Relay
Actuator Module are as follows:
<module address>.1260-12 RELAY ACTUATOR MODULE
<module address>.BBM
<module address>.END
The response to the PSETUP command consists of a header on
the first line. The header describes the model number. The next
line designates the setup mode for the scanning which, by
default, is Break-Before-Make (BBM). The last line containing
the “END” characters denotes no more information to report.
PDATAOUT
Command
The PDATAOUT command causes the specified module to
transmit the state of the CLOSED relays (within the switching
module) to the 1260 Controller. The syntax used is:
PDATAOUT <module address>[;<module address>]
[;<module address>]
The responses to the PDATAOUT command are as follows:
<module address>.1260-12 RELAY ACTUATOR MODULE

1260-12 User Manual
EADS North America Defense Module Specific Syntax 3-3
Test and Services, Inc. ©1993
<module address>.<channel>[,<channel>][,<channel>]......
<module address>.END
The response to the PDATAOUT command consists of a header
on the first line, as with the PSETUP response. The next line
details the channels currently closed on the module, and is blank
when no channels are closed. Again, the last line is denoted by
the "END" string of characters.
