Pin No.	Pin Name	Function	I/O
1	NC	No connection	—
2	RTTY	RTTY key input	I
		Audio output from the transceiver
		• Connect to the audio input of the TNC, MCP, or PC (or PC
		interface connection).
		• Audio output level is independent from the AF control setting.
3	ANO	• Audio output level can be changed by adjusting the value	O
		in Menu No. 67. Set the value to a moderate audio output
		level. The default value of 4 is approximately 0.5 Vp-p, which
		is a standard modulating signal. The settings of 0 ~ 9 vary
		from approximately 0 Vp-pto 1.2 Vp-p.

4	GND	Ground	—
		Transceiver squelch control
5	PSQ	• Connect to the squelch input of the TNC, MCP, or PC	O
		connection interface.
		• Squelch open: Low impedance
		• Squelch closed: High impedance
6	NC	No connection	—

8	GND	Ground	—
		PTT input for data communication
9	PKS	• Connect to the PTT output of the TNC, MCP, or PC	I
		connection interface.
		• Microphone audio input mutes when transmitting.
10	NC	No connection	—
		Audio input for data communication
		• Connect to the audio output of the TNC, MCP, or PC (or PC
		interface connection).
		• Audio input level is independent from the microphone gain
11	ANI	(set with the [MIC] key).	I
		• Audio input level can be changed by adjusting the value in
		Menu No. 66. The default value of 4 is approximately 10
		mVrms, which is a standard modulating signal. The settings
		of 0 ~ 9 vary from approximately 0 mVrms to 1 mVrms.
