To reconfigure the RFC interconnect, do the following:
1. Remove the four screws which retain the RFC cover and remove
the cover.
2. The RF unit may be identified by following the connection from
the port labelled "IF" on the rear of the RFC. This connection
terminates at the RF unit. The diplexer may be identified by
following the connection from the "Antenna" port on the rear
of the RFC. This connection terminates at the circulator, which
in turn is connected to the diplexer, illustrated in the figure
below.
3. Unscrew the cable assemblies from the ports labelled "Tx" and
"Rx" on the RFC, and the ports labelled "2422" and "2462" on
the diplexer, depending on the frequency Plan (Plan A or Plan
B).
4. Unscrew the cable assembly from the port labelled "Antenna"
on the diplexer.
5. Remove the four screws from the bottom of the RFC that hold
the diplexer in place.
6. Turn the diplexer over revealing the opposite frequency plan
(from Plan A to Plan B, or vice versa).
7. Realign the diplexer with the screw holes and replace the four
screws that attach it to the bottom of the RFC.
8. Re-attach the loose cable assembly (from step 4) to the port
labelled "Antenna" on the diplexer.
