Section 2 Installation

9.Reattach the cable assemblies from the ports labelled “Tx” and “Rx” on the RFC and the ports labelled “J1” and “J2” on the diplexer. Cable connections should be aligned to each other as follows.

Plan A	Plan B
RF converter Tx connected to	RF converter Tx connected to
Diplexer Port J1	Diplexer Port J2
RF converter Rx connected to	RF converter Rx connected to
Diplexer Port J2	Diplexer Port J1
10. Replace and secure the RFC cover.

For mastmounted systems, do the following to reconfigure the RFC interconnect:

1.Remove the lid of the mast RFC.

2.Disconnect the three cables attached to the diplexer. The diplexer may be identified by following the antenna connector to the middle connector of the diplexer. Leave the cables in the same positions.

3.Remove the two screws securing the diplexer and rotate the diplexer to reveal the opposite frequency plan label.

4.Reinstall the two screws and reattach the cables in the same positions – Minimum bend radius on cables is 3/4 inches (2 cm). Exercise care in handling and forming bends in these cables.

5.Reinstall the lid of the mast RFC.
