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.

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 and reported.
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.
Immediately notify the carrier if any damage is apparent.
4. Have a qualified person check the instrument for safety before
use.
CAUTION
ALWAYS PERFORM DISASSEMBLY, REPAIR AND
CLEANING AT A STATIC SAFE WORKSTATION.
Reshipment
Instructions 1. Use the original packing when returning 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 an ESD Shielding bag and use foam to surround and
protect the instrument.
3. Reship in either the original or a new shipping carton.

NOTE:
The <module address> used here is not the VXIbus
defined Logical Address of the 1260 Series Master. It
is unique 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. Refer
to the Installation Section of the 1260 Series VXI
Switching Cards Manual, Part Number 980673-999, for
more information.
Theory of
Operation The fundamental commands for the 1260-51 RF Matrix are the
OPEN and CLOSE commands. The commands for 1260-51 differ
in that users specify the input and output port rather than the
relays. Then a unique path for the input-output, permanently
stored in hardware, is established to make the path from input
port to output port.
If a new path requested is in conflict with the other paths already
made, all previous paths using that conflicting relay will be
opened to make a new path. Furthermore, relays that were part
of the previous paths will be opened to make them available for
future usage.
Syntax The Module Specific Syntax for the 1260-51 RF Multiplexer is as
follows:
OPEN|CLOSE <module address>.<4-digit I/O>[;<module address>.<4-digit I/O >]
Example:
OPEN <module#>.<starting I/O >-<ending I/O >
CLOSE <module#>.<starting I/O >-<ending I/O >
OPEN/CLOSE will make the path for given input -output pairs.
Often each path involves multiple relays and thus any previous
path which uses relays requested by the new path will be
destroyed to make the new path.
OPEN 1.0010
00: specify input channel
10: specify output channel
Multiple paths may be listed in a single line of instruction, but be

careful about implicit exclusion. The implicit exclusion means that if
path A belongs to 2X6 matrix and path B belongs to 2X36 matrix,
path A cannot coexist with path B. Thus the matrix of most recent
path will prevail.
Examples:
CLOSE 1.0020, 0030 will cause only 0030 to be closed. (Same
input channel cannot be directed to different output). CLOSE
1.0020, 0130 will cause both 0020 and 0130 to be closed.
(Different inputs for different output; and these two paths belong to
the same matrix configuration). CLOSE 1.0020, 0601 will cause
only 0601 to be closed. (Apparently, input and output pair seem
different from each other. But 0020 belongs to 2X12 matrix
configuration and 0601 belongs to 2X6. Therefore, making 0601
will force 0020 to be opened because of conflicting matrix
configuration.)
SCANLIST <module#.<starting I/O >-<ending I/O >
Example:
After sending 'SCAN 1.0000-3550', issuing 'TRIGGER' command
will close valid pairs of I/O channels in an increasing order.
PDATAOUT <module address>; [<module address>]; [<module address>]...
PDATAOUT exactly same as any other 1260 modules.
EXCL <module#>.<starting I/O >-<ending I/O >
All input-output channels specified in EXCL shall be closed in
mutually exclusive manner. That is, only one I/O channel can be
closed.
Without EXCL, two paths of the same matrix configuration can
coexist. For example:
CL 1.0020
CL 1.0130 {two paths are connected}
EXCL 1.0-3550
CL 1.0020
CL 1.0130
(Only latest path is connected; 0130 in this case.)

Note: There is implicit exclusion built in the firmware for each
different matrix configuration. For example, closing a path in 2x36
mode will destroy the other paths belong to 2x6 and 2x12.

where <module address> is the switch card address.

digit input port><2-digit output port>]...
<2-digit input port> is the input port
<2-digit output port> is the output port.
Valid input port is 2 digit numeric between 00 and 35.
Valid output port is 00, 10, 20, 30, 40, 50 if input port is
between 00 and, 05;
01, 11, 20, 30, 40, 50 if input port is between 06 and 11;
02, 12, 21, 30, 40, 50 if input port is between 12 and 17;
03, 13, 21, 31, 40, 50 if input port is between 18 and 23;
04, 14, 22, 32, 40, 50 if input port is between 24 and 29;
05, 15, 22, 32, 40, 50 if input port is between 30 and 35;
If these input pairs are incorrectly provided by a user, error (code
3) will be noted.
