The RS-232 Control port connects via modular RS-232 to any compatible device.
RX is located on pin 3, TX on pin 6, and GND on pin 7. Use an Audio Authority
serial to System Bus adapter to connect devices such as a TS04 touch panel
for control.
12V DC Power
Connect 12V power adapter to Power Input. The power Bus Out may be used to
power more Audio Authority compatible devices within the power supply’s capacity
by using an 801-077 power extension cable. The Power LED is visible from the
side view.
Analog Audio
