RS-232/RS-422/RS-485 connector — A 5-pole captive screw connector for

input from a computer or third-party controller using Serial Control Protocol

commands or control software for Windows

to remotely control the switcher.

Serial control setting DIP switch — Allows the switcher to be configured to

accept RS-232 (all switches up) or RS-422/RS-485 (all switches down)

communication standard.

DIP switch settings change according to the standard used. Higher standards

require a different signal type. DIP switch settings make subtle adjustments to

signal type. See chapter 5 - Remote Control for additional information.

AC power — Standard AC power connector for a power source of

100 – 240VAC, operating at 50/60 Hz.

AC Fuseholder — Remove this to change out the AC fuse.

Audio output group — Four (MSG0804) or eight (MSG0808), 5-pole captive

screw connector for balanced/unbalanced stereo audio output from the audio

input. See Audio input and output in this chapter.

Audio input group — Eight, 5-pole captive screw connector for balanced/

unbalanced stereo audio input.

Pay special attention to the right channel wiring. The + and – layout

differs from most other Extron products.
