Input terminals to transmit the repeater in rela-
tion to the external equipment. An opto-isolator
is provided to facilitate PTT signals.
Output terminal for AF signals from the AF de-
tector circuit via the bandpass filter. Output level
is fixed, regardless of [AF] control.
Input terminal for the modulation circuit.
Output terminal for squelch condition
(Open/Close). An opto-isolator is provided to fa-
cilitate BUSY signals.
High voltage=PTT ON (transmits)
Hi-Z=PTT OFF
Output impedance: 600 Ω
Input impedance: 600 Ω
Open collector=BUSY OFF
0 V=BUSY ON (Squelch is opened)
