The indicators on this screen display the status of the input commands described in Table 3-70 on page 3-

panel. The connector pin numbers are provided.
Note
The UAX Transmitter will default to standalone mode when no connections are made to the parallel I/O.
If the TCU present signal is asserted at anytime, the transmitter will be forced into dual mode for opera-
tions with a TCU. The transmitter will remain in dual mode until power cycled with the TCU present sig-
nal de-asserted. When in dual mode, the parallel I/O will be operational regardless of remote control
setti
ng enabled/disabled. When in standalone mode, the parallel I/O will be disabled when remote control
is disabled
