Connector Pin Assignments
62 Transceivers 6200 Series DV14307.03 Issue 06 February 2021
External Power ON
J1-25 /EXT_ON IN
ACTIVE state - closed contact to GND
• With the External Power ON input it is possible to power "ON" the system when this pin is
connected to ground.
Push-To-Talk (/PTT)
P1-17 /PTT1 IN
ACTIVE state - closed contact to GND
J1-5 /PTT2 IN
ACTIVE state - closed contact to GND
• There are two Push-To-Talk inputs available /PTT1 and /PTT2 (e.g. one for the pilot and
one for the co-pilot).
• Each input has an internal pull up.
• While the input is connected to ground a current of < 1 mA flows.
o The transceiver enters transmit operation, if one or both inputs are connected to
ground.
• According to microphone(s) configuration, the signal from particular inputs can or cannot
modulate transmissions.
Power Indication (/PWR_EVAL)
P1-24 /PWR_EVAL OUT
Device "OFF" - open circuit
Device "ON" - closed circuit to GND
(max. 100 mA)
• This output shows the transceiver status, "ON" or "OFF", with an open collector function.
• The output internally connects to ground when the device is "ON".
• A current of maximum 100 mA can flow to drive e.g. an external relay.
• The output has high impedance if the device is "OFF".
Notice: Connect a protection diode in parallel to the external relay to prevent damage of
this output.
VHF Channel Signal Indication (/SQL_EVAL)
J1-4 /SQL_EVAL OUT
Indicates presence of the VHF channel’s signal
on the audio outputs.
• It is an open collector output type.
• The output internally connects to ground when the device receives signal on the selected
VHF channel and this audio signal is available on audio outputs.
• A current of maximum 100 mA can flow to drive e.g. an external relay.
• The output has high impedance if the device is turned off.
