COMMUNICATIONS SYSTEM

11-13. CABLES ARE TOO SHORT; BDAR INSTALLATION

General Information:

This procedure gives methods for connecting two or more cables together to make the

desired cable length. This procedure is for CX-4723 cable. Other types of cables can

be extended using similar methods.

Limitations:

●

Preferred method - none

●

Alternate methods - possible lowered volume

Personnel/Time Required:

●

1 soldier

●

20 minutes

Materials/Tools:

●

Preferred method:

Box, control, C-10456 or C-2298 VRC

●

Alternate method:

Gun, soldering

Solder, rosin-core

Other Option(s):

o

See other methods in electrical chapter of TM 9-2350-276-BD

Procedural Steps:

1.

The preferred method uses a junction box such as a C-2298 control box between

two CX-4723 cables.

Another method is fabricating a junction by removing the 3-801 and 3-804

connectors from a C-2298 control box.

Solder jumper wires between the

corresponding connector pins.

Insulate the jumper wires and the rear of the

connectors.

A less desirable method is to remove one connector from each cable and splice the

corresponding wires from the two cables together. Insulate the splice.

Record the BDAR action taken.

When the mission is complete, as soon as

practicable, repair vehicle using standard maintenance procedures.
