4-6 kW UHF Translator Chapter 2, System Description
837B, Rev. 0 2-10
Remote Monitoring and Operation of the
Translator is provided through the Jacks
(J8, J9 & J10) located on (A9) the
Remote Interface Assembly located on
the rear of the UHF Exciter Assembly.
Jack (J7) should have a dummy plug
connected to it, which has a jumper
connected between Pins 1 & 2, that
provides the Interlock to the Exciter
needed to operate the Translator. If the
Jumper is missing, the Translator will not
switch to Operate. If remote connections
are made to the Translator they should
be made through the plugs provided in
the Installation Material as noted on the
Interconnect Drawing (1278-8400) for
the Single UHF Exciter.
The On Channel RF Input to the Receiver
Tray connects to the Translator through
(A9) the Remote Interface Assembly at
J1, "N" type connector, for 50Ω Input or
J3, "F" type connector, for 75Ω Input.
The remote connections, listed in Table
2-11, are made to the (A9) A/V input and
remote interface assembly mounted at
the top, facing the rear of the UHF
Exciter Cabinet. The remote connections
are made to jacks J7(9 Pos D con), J8(25
Pos D con), J9(37 Pos D con) and J10(25
Pos D con) on the assembly. Refer to the
exciter interconnect drawing (1278-
8400) for the proper pin remote
connections.
