Base Station Link

This RJ-45 type jack allows the connection of wireless talk around (WTA) to two base stations of the same frequency bands. This allows WTA on I/C channel A and WTA on I/C channel B to be the carried through to the other base station attached together via this jack.

WTA channel A and channel B is “contained” within a base station unless the transmit power is off. If it is off, the WTA audio is routed through the base station link cable to the other base that has its transmitters on.

A cable to accomplish this task is NOT supplied, but can eas- ily be made with common category 5 (CAT-5) wiring.

In fact, the most common 10BaseT ethernet patch cables, 568-B wired cables, can be used to connect bases together. The required cable is shown below.

The regular two-wire intercom channels are passed from base to base via the wired intercom cables and do not require the base station link cable.
