Pin Name Description
NC No connection.
GND Connect to ground.
Input terminal to transmit the trans-
SEND ceiver in relation to the external equip-
ment. (Grounded: transmits)
MOD Input terminal for the modulation cir-
cuit.
Output terminal for AF signals from
AF the AF detector circuit. Output level is
fixed, regardless of [AF] control.
Output terminal for squelch condition
SQLS (Open/Close). Outputs grounded level
signal when squelch is opened.
13.8 V Output terminal for 13.8 V DC, in re-
lation to the [POWER].
ALC Input terminal for ALC control.
Pin Name
DATA IN Input terminal for data (common for both 1200 and 9600 bps)
GND Ground line for the DATA IN, DATA OUT and AF OUT.
PTTP Transmits when this terminal is grounded.
DATA Received data output terminal for 9600 bps operation.
OUT
AF OUT Received data output terminal for 1200 bps operation.
SQL Output terminal for squelch condition (Open/Close). Outputs grounded level signal
when squelch is opened, +8 V level signal when squelch is closed.
Pin Name
NC No connection.
GND Ground line for the DATA IN, DATA OUT and AF OUT.
NC No connection.
DATA Received data output terminal for 9600 bps operation.
OUT
AF OUT Received data output terminal for 1200 bps operation.
SQL Output terminal for squelch condition (Open/Close). Outputs grounded level signal
when squelch is opened, +8 V level signal when squelch is closed.
