NOTE: If your transmitter does not
contain the (A12) A/V input and remote
interface assembly, the remote
connections are made directly to the rear
of the VHF exciter at J10 a 25 pos “D”
connector or J11 a 37 pos “D” connector
and to each of the VHF amplifier trays at
J3 a 25 pos “D” connector. Refer to the
interconnect drawing (1304391) to
confirm the remote pin connections.
