COM AUDIO OUT LO
This is an analog output from the KSN 7xx with the following characteristics:
J2-6
COM MIC AUDIO IN HI
J2-26
COM MIC AUDIO IN LO
This is an analog input to the KSN 7xx with the following characteristics:
J2-71
COM MIC KEY
This input is normally open, with a momentary GND applied when a switch is pressed. When the switch
is open, the KSN 7xx disables the COM transmitter and sidetone; when grounded the COM transmitter
and sidetone are enaled.

and sidetone are enaled.
J2-53
TRANSMIT INTERLOCK
This discrete input signal may be optionally activated from remote equipment that might interfere with
the VHF COM. The input is normally open, and is activated momentarily as long as a GND is applied to
it. When the input is open, the COM receiver operates normally with normal sensitivity and sidetone.
When this input is held low, the COM receiver is desensitized. If held low for longer than 30 seconds
continuously, the receiver reverts to the normal mode until the signal is released (open) and pulled low
again.
