1 PANEL DESCRIPTION
M@ Rear panel
@ ANTENNA CONNECTOR [ANT]
Accepts a 50 Q dual band antenna with a PL-259 connec-
tor. (p. 14)
@ SPEAKER JACK [SP]
Connects a 4-8 Q speaker, if required. Outputs the se-
lected band’s audio.
© DATA JACK [DATA]
6-pin mini DIN jack to connect a TNC, etc. for packet op-
eration.
77 NOTE: The connection between this jack and the TNC
4%, differs depending on whether 1200 bps or 9600 bps op-
4% eration is chosen in initial set mode (p. 63). See right
7, for pin assignments. —
@ POWER RECEPTACLE [DC13.8V]
Accepts 13.8 V DC with the supplied DC power cable.

@ DATA IN
Input terminal for data transmit. See p. 63 for details «
how to toggle data speed between 1200 and 9600 bps.
@ GND
Common ground for DATA IN, DATA OUT and AF OUT.
@) PTTP
PTT terminal for packet operation only. Connect ground
transmit data.
@ DATA OUT
Data out terminal for 9600 bps operation only.
© AF OUT
Data out terminal for 1200 bps operation only.
© SQ (squelch out)
Becomes high (+5V) when the transceiver receives a SI
nal which opens the squelch.
¢ To avoid unnecessary TNC transmission, connect squelch to t
TNC to inhibit transmission when receiving signals.
¢ Keep audio output at a normal level, otherwise a “SQ” signal \
not be output.
