Serial Communication Power Sensor Installation
The Bird 4043 Series Directional Power Sensors are designed to be used for
continuous power monitoring of Land Mobile Radio (LMR) systems. The 4043
can provide real-time RF forward and reflected power and VSWR
measurements.
This procedure is an example of one possible cable configuration, based on the
connection diagram in
Figure 3
.
1. Disable RF power for transmission lines to be disconnected.
2. Connect combiner's RF output cable to the 4043 RF input.

3. Connect 4043's RF output connector to the antenna cable.
4. Repeat step
1
through
3
for any additional 4043 power sensors.
5. Install RJ-25 termination plug in unused digital sensor RJ-25 port on the rear
panel of the CPM (if available), or in the last sensor installed in the digital
sensor chain.
6. Connect a data/power cable from the CPM to 4043 power sensor.
WARNING
Leaking RF energy is a potential health hazard. Never attempt to connect or
disconnect equipment from the transmission line while RF power is being
applied. Severe burns, electrical shock, or death can occur.
