Remote Control

The MediaLink Switcher can be controlled by using its front panel controls; an

optional Extron infrared remote control (the MLA-Remote, for example) and an

Extron IR Link signal repeater; a MediaLink Controller; or another RS-232 control

device or computer. See Control Connection on page 2-7 for wiring diagrams and

system examples.
