GRemote Tally port — If desired, to remotely identify the currently selected input, plug a locally-constructed device into this 3.5 mm, 4-pole captive screw connector. Connect the power wire for the device into the +V pin and connect the ground wire for the each indicator into the corresponding tally output pin: 1, 2, or 3.

When an input is selected, by either contact closure or front panel selection, the corresponding tally output pin shorts to ground, closing the circuit and lighting the connected indicator (LED).

HRemote RS-232 port — Plug a serial RS-232 device into the switching transmitter via this rear panel 3.5 mm, 3-pole captive screw connector for remote control of the switching transmitter.
