PANEL DESCRIPTION

rANTENNA CONNECTOR [ANT]
Connects a 50 antenna with a PL-259 connector and a
50 coaxial cable.
tPOWER RECEPTACLE [DC13.8V]
Accepts 13.8 V DC ±15% with the supplied DC power
cable.
NOTE: DO NOT use a cigarette lighter socket as a
power source when operating in a vehicle. The plug
may cause voltage drops and ignition noise may be su-
perimposed onto transmit or receive audio.
DDATA socket Pin assignment
qDATA IN
Input terminal for data transmit.
See p. 100 for details on how to
toggle data speed between
1200 (AFSK) and 9600 bps
(G3RUH, GMSK).
wGND
Common ground for DATA IN,
DATA OUT and AF OUT.
ePTT P
PTT terminal for packet operation only. Connect ground to
transmit data.
rRS232 OUT
Data out terminal for RS232 connection (GPS operation).
tDATA OUT
Data out terminal for 9600 bps operation only.
yAF OUT
Data out terminal for 1200 bps operation only.
uRS232 IN
Input terminal for RS232 input.
iP SQL
Becomes high (+5 V) 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 P SQL signal
will not be output.
ANTENNA INFORMATION
For radio communications, the antenna is of critical impor-
tance, to maximize your output power and receiver sensi-
tivity. The transceiver accepts a 50 antenna and less
than 1:1.5 of Voltage Standing Wave Ratio (VSWR). High
SWR values not only may damage the transceiver but also
lead to TVI or BCI problems.
