2. Insert the wire into the pin and crimp with one of the recommended (or equivalent) crimping tools.
3. Insert the pin into the D-sub connector housing locations as specified by the interconnect drawing.
4. Verify the pin is properly engaged into the connector by gently tugging on the wire.
5. Route and secure the cable run from Airtext to the other units away from sources of electrical noise.
See cable and wiring above for the electrical characteristics of all input and output signals. Required
connectors and associated hardware are supplied with the connector kit. See Figure 3 for sample
interconnect wiring diagrams.

Backshell Assembly Procedure
The parts for the connector and backshell assembly for Airtext installations are listed above.
Connector and Backshell should be assembled in such a way that the shield (if used) of the cable is
attached to the ground return or airframe at one end only. If the shield is connected to the connector
backshell at the Airtext end, then it should not be connected to the airframe at the far termination or mid
disconnects.
Shielded Cable Preparation
1. At the end of the shielded cable, strip back a 2.5" maximum length of the jacket to expose the braid.
Remove this exposed braid. Carefully score the jacket 1/4" to 5/16" from the end and remove the jacket to
leave the braid exposed.
NOTE
Solder sleeves with pre-installed shield drains may be used instead of separate shield terminators and
individual wires. Using solder sleeves with pre-installed lead effectively takes the place of step 7.
2. Connect a 22 AWG wire to the exposed shield of the prepared cable assembly. AC 43.13 may be a
helpful reference for termination techniques.
