DATA IN
Input terminal for data transmit. (1200 bps: AFSK/9600 bps: G3RUH, GMSK)
2
GND
Common ground for DATA IN, DATA OUT and AF OUT.
3
PTT P
PTT terminal for packet operation. Connect to ground to activate the transmitter.
When grounded, microphone input (pin 6) of [MIC] connector will be disconnected.
When grounded, microphone input (pin 6) of [MIC] connector will be disconnected.

DATA OUT Data out terminal for 9600 bps operation only.
5
AF OUT
Data out terminal for 1200 bps operation only.
Squelch out terminal. This pin is grounded when the transceiver receives a signal
which opens the squelch.

SQL
• To avoid interfering transmissions, connect squelch to the TNC to inhibit transmission
when squelch is open.
• Keep RF gain at a normal level, otherwise a “SQL” signal will not be output.
