Pin Name
Input terminals to transmit the repeater in rela-
1 –PTT
tion to the external equipment. An opto-isolator
2
is provided to facilitate PTT signals.
+PTT
Output terminal for AF signals from the AF de-
3 –AFOUT
tector circuit via the bandpass filter. Output level
4 +AFOUT
is fixed, regardless of [AF] control.
5 –EXTMOD
Input terminal for the modulation circuit.
6 +EXTMOD
Output
7 –BUSY
(Open/Close). An opto-isolator is provided to fa-
8 +BUSY
cilitate BUSY signals.

!4
Output terminal for busy signal.
Output terminal for coaxial switching (antenna switching)
signal.
Input terminal for master/slave signal.
Input terminal for selecting memory channel.
Input terminal for selecting memory channel.
Input terminal for repeater/base operating mode switching
signal.
Input terminal for monitor function.
Input terminal for continuous tone (CTCSS/DTCS) signal.
Input terminal for the modulation signals applied to input of
the splutter filter circuit.
Input terminal for the modulation signal applied to input of
the pre-emphasis circuit via the bandpass filter.
Output terminal for AF signals from the AF detector circuit
via the bandpass filter. Output level is fixed, regardless of
[AF] control.
Output terminal for AF signals from the AF detector circuit.
Output level is fixed, regardless of [AF] control.
Output terminal for +15V DC while in AC operation. (While in
DC operation, same as input DC.)
Output terminal for transmission state.
