Transmit cable

This section explains how to connect the transmit and receive cables to the radio assembly.

Connect the transmit cable to the transmitter as follows:

1.From inside the building, disconnect the IDU power supply.

2.Go outside and connect the transmit cable (marked with blue electrical tape) to the transmitter connector marked IFL, as shown in Figure 31.

Use a weatherproof connector.
