NAME DESCRIPTION
Controls RTTY keying
Connects to ground.
Input/output pin.
Goes to ground when transmitting.
When grounded, transmits.
Modulator input.
Connects to a modulator
AF detector output.
Fixed, regardless of [AF] position in
default settings. (see notes below)
Squelch output.
Goes to ground when squelch opens.
13.8 V output when power is ON.
ALC voltage input.
NAME DESCRIPTION
Regulated 8 V output.
Same as ACC 1 pin 2.
Same as ACC 1 pin 3.
Band voltage output.
(Varies with amateur band)
Same as ACC 1 pin 8.
Activates [X-VERTER] input/output
when "HIGH" voltage is applied.
Same as ACC 1 pin 7.
