LPU TX INTERFACE & USER REMOTE CONNECTORS
Additional notes:
The Remote Control, /Exciter Active, and Auto/Manual commands (from Tx
Interface) don’t work in standalone operation.
The VAX transmitter will default to standalone mode when no connections are
made to the TX Interface. If the /TCU present signal is asserted at anytime,
the transmitter will be forced into dual mode for operations with a TCU. The
transmitter will remain in dual mode until power cycled with the /TCU Present
signal de-asserted.
When in dual mode, the Tx Interface will be operational regardless of Remote
Control Enabled/Disabled. TCU always in control.
When in standalone mode, the TX Interface will be disabled when remote
control is disabled.
