q ANTENNA CONNECTOR [ANT]
Accepts a 50 dual band antenna with a PL-259 connec-
tor. (p. 14)
w SPEAKER JACK [SP]
Connects a 48 speaker, if required. Outputs the se-
lected bands audio.
e DATA JACK [DATA]
6-pin mini DIN jack to connect a TNC, etc. for packet op-
eration.
NOTE: The connection between this jack and the TNC
differs depending on whether 1200 bps or 9600 bps op-
eration is chosen in initial set mode (p. 63). See right
for pin assignments.
r POWER RECEPTACLE [DC13.8V]
Accepts 13.8 V DC with the supplied DC power cable.
D DATA JACK PIN ASSIGNMENTS
q DATA IN (1200 bps: AFSK
9600 bps: G3RUH,
GMSK)
w GND
e PTTP
r DATA OUT (9600 bps)
t AF OUT (1200 bps)
y SQ
q DATA IN
Input terminal for data transmit. See p. 63 for details on
how to toggle data speed between 1200 and 9600 bps.
w GND
Common ground for DATA IN, DATA OUT and AF OUT.
e PTTP
PTT terminal for packet operation only. Connect ground to
transmit data.
r DATA OUT
Data out terminal for 9600 bps operation only.
t AF OUT
Data out terminal for 1200 bps operation only.
y SQ (squelch out)
Becomes high (+5V) when the transceiver receives a sig-
nal which opens the squelch.
To avoid unnecessary TNC transmission, connect squelch to the
TNC to inhibit transmission when receiving signals.
Keep audio output at a normal level, otherwise a SQ signal will
not be output.
