6. SUPPLYING POWER TO THE UNIT
The TRACER 4108/4208 can operate from a supply between 21 and 60 VDC, with either polarity
referenced to ground. Power supplies should be able to provide up to 25 watts at the selected voltage. A
dual pin terminal plug accepts power at the rear panel of the unit, providing a + and - polarity reference
point. Adapters for this plug are available (P/N 1175043L2) and are furnished with the unit and optional
power supply (P/N 1280650L1).
7. MOUNTING OPTIONS
Install the TRACER 4108/4208 in a location that requires minimal antenna feedline length (the loss in this
cable directly affects overall system performance). The TRACER 4108/4208 is designed to be mounted in
a rack. If multiple units are installed in one location, one half inch of spacing is recommended above and
below the unit.
8. CONNECTING THE T1 INTERFACE
The physical T1 interface is provided using eight RJ-48C jacks for transmit and receive. The provided
straight through T1 interface cables can be used to interface to any standard T1 DTE device.
