3-6 Options and Accessories Installation: Remote-Mount Accessory Installations for W3 Model
3.4 Remote-Mount Accessory Installations for W3 Model
Accessories for the W3 remote mount handheld control head are connected through the J3
connector located in the remote cable assembly. It requires a different P3 connector (supplied). This
P3 connector is a 15 pin D-sub (see
Figure 2-11 in Chapter 2), unlike the 26-pin accessory connector
assembly (see Figure 3-9). The terminals that are required are the same for both. Therefore all
accessories will be compatible with all XTL 5000 radios.
1. Remove P3 connector from remote harness by pulling it out.
2. Remove the two screws holding the 15-pin D-sub.
3. Loosen the strain-relief screw located adjacent to the wire-exiting hole in the back of the
connector cover.
4. Extract the D-sub by pushing the wires into the cover.
5. Route the accessory wires through the hole and insert the male pin into the appropriate
location. A tool is available to remove the male terminals if service is required. (
See Appendix
A: Replacement Parts Ordering
.)
6. While holding the cover, pull each wire to achieve a uniform slack, then pull all wires until the
D-sub is seated against the cover.
7. Reattach the two screws to secure the D-sub, and tighten them appropriately.
8. Tighten the strain-relief screw adjacent to the wire outlet hole appropriately.
9. Reconnect the P3 connector onto the remote cable assembly.
10. Secure all wires using tie straps or electrical tape to prevent damage or shorting.
