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.

INTRODUCTION
1260-50C/D
200MHz
Multiplexer
Module
The 1260-50C/D provides eight/sixteen 1 x 4 multiplexers (refer
to the Functional Diagram Figure 1-2). Relays CHI9, 29,..., 159
provide for the connections between the adjacent 1 x 4 groups
under software control. Thus, the 1260-50C/D module can be
configured as multiplexers up to 1 x 39/1 x 79 size. The 200
MHz bandwidth is guaranteed for all possible multiplexer sizes.
The only restriction is the groups not needed for a connection
between any two channels have to be disconnected to achieve
200 MHz bandwidth.

Coaxial cables have been tested to 1GHz, and are available as
an option. Each cable contains a coaxial pin at each end. The
cables are available in 2, 6, and 12 feet, and can be cut by
customers to any length. (Example: The 6-foot cable can be cut
to two 3-foot or one 2-foot and one 4-foot cable.) Coax pins (P/N
602220-900) suitable for RG316 coaxial cable may be purchased
separately. The 1260-50C requires 40, and the 1260-50D
requires 80. To crimp coaxial pins, use crimp tool Hytool M10S-1
from Burndy.

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.
Immediately notify the carrier if any damage is apparent.
4. Have a qualified person check the instrument for safety
before use.
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 plastic sheeting 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 to the 1260-50C/D is described in
the Installation section of the 1260 Series VXI Switching Cards
Manual.
Module
Installation
Installation of the 1260-50C/D 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 switch, SW1-5 should be set OFF for
the 1260-50C module and ON for the 1260-50D module.

NOTE
The 1260-50C/D Coaxial switching module is
supported by the Option 01 Operating Systems at
Revision levels 24.1 and above.
The 1260-50C/D RF Multiplexer supports the OPEN, CLOSE,
PSETUP, RESET and PDATAOUT commands.
Syntax The module specific syntax for the 1260-50C/D RF Multiplexer is
as follows:
OPEN OPEN <module address>.<channel>[ ;<module address> . <channel>J
where <module address> is the address.
<channel> is the relay to be closed to connect an input to
the output.
Note that Channels remain closed until opened by an OPEN
command, RESET command, VXI hard or soft reset, or power-
off.
The range of values for <channel> is:
1260-50C: 00-04, 10-14, 19, 20-24, 29, 30-34, 39, 40-44, 49,

Module Specific Syntax 3-2
CLOSE The Module Specific Syntax for the CLOSE command is the
same as for the OPEN command.
PSETUP The PSETUP command causes the specified module setup to be
transmitted to the VXI Controller. The syntax used is:
PSETUP <module address> [ ;<module address>] [;<module address>]
where <module address> is the address.
The responses to the PSETUP command for the 1260-50C/D
multiplexer is as follows:

PDATAOUT The PDATAOUT command causes the specified module to
transmit the CLOSED state of the relays fitted to the switching
module to the 1260 Controller. The syntax used is:
PDATAOUT <module address>[ <module address>] [;<module address>]
The responses to the PDATAOUT command is as follows:
