(80) AUX I/O

Figure 2-19 Rear Panel AUX I/O pin out
The AUX I/O jack is an 8-pin DIN receptacle
used for interfacing accessory device
requiring audio in/out connections, FSK
connections and/or an auxiliary PTT input.
An 8-pin DIN connector (p/n 46172) and an
accessory cable, (p/n 46176) have been
provided as part of the ORION II packing kit
for easier connection of the AUX I/O jack to
accessory equipment. The cable is color-
coded as follows: WHITE = pin 1, audio
input. YELLOW = pin 4, line level audio
output. RED = pin 5, no connection.
BLACK = pin 3, push to talk. Ground from
the 46176 cable is connected to pin 2.
Pin 1 is used for a line level audio input from
an accessory device (like a TNC or sound
card for digital mode operation). There is a
gain control available for this input
accessible through the menu system.
See the description under SSB MENU in
Chapter 3.
Pin 2 is ground.
Pin 3 is a PTT connection. In SSB and AM
modes, when grounded, the radio begins
