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.

Chapter 2
INSTALLATION INSTRUCTIONS
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.
3. Reship in either the original or a new, sturdy shipping carton.
Option 01T
Installation Installation of the Option 01T into the 1260-64M is described in
the Installation section of the 1260-Series VXI Switching Cards
Manual. Note that lockout keying for the double-wide 1260-64M
module differs from that described in the 1260 manual section.

User Manual 1260-64M
Installation Instructions 2-2 Racal Instruments 2002
Lockout Keys Lockout keying is not available for the 1260-64M. The system
integrator must ensure that the module installed to the left and
right of the 1260-64M has no conflict with the Local Bus
implementation.
Module
Installation Installation of the 1260-64M 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 should be set as follows:
1260-64M 5=OFF 6=OFF (factory setting)
Relay Bank
Configuration If either of the 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.
The first consideration when configuring the relay banks is
whether the bank is to act as a source driver or a sink driver. (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.
The next consideration is the source of power for the external
loads on Bank A. If an external supply is to be used, the
jumpers at locations W3 and W4 are to be removed. If the VXI
+5V supply is to be used, eight jumpers are to be installed at
location W3. (1-2, 3-4, 5-6, etc.) If the VXI +12V supply is to be
used, three jumpers are to be installed at location W4 (1-2, 34,
and 5-6) If the VXI +24V supply is to be used, the three jumpers
are to be installed at location W4 (11-12, 13-14, 15-16).
The final consideration is the source of power for the external
loads on Bank B. If an external supply is to be used, the
Artisan Scientific - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisan-scientific.com

User Manual 1260-64M
Racal Instruments 2002 Installation Instructions 2-3
jumpers at locations W8 and W9 are to be removed. If the VXI
+5V supply is to be used, eight jumpers are to be installed at
location W8. (1-2, 3-4, 5-6, etc.) If the VXI +12V supply is to be
used, three jumpers are to be installed at location W9 (1-2, 3-4,
and 5-6) If the VXI +24V supply is to be used, the three jumpers
are to be installed at location W9 (11-12, 13-14, 15-16).
The right cover can now be reinstalled on the module.
Microwave Plug-In
Installation Microwave plug-in modules typically are installed at the factory
prior to shipment. Follow the instructions below to install a
microwave plug-in into the carrier assembly (407816).
Each microwave plug-in consists of a connectorized relay and a
unique cable assembly. Remove the right side cover (14
mounting screws) and feed the “P2” end of the cable assembly
through the opening in the front panel of the carrier. Mate the
“P2” connector (and “P3” if necessary) within the appropriate
header as indicated in Table 2-1. Secure the plug-in to the
carrier front panel with the hardware supplied. Replace the right
side cover and secure.
