    Controlling other devices The MLC 226 Series offers two methods of projector and source device control: RS-232 or infrared (IR). The MLC can learn IR signals from remote controls to communicate with sources such as VCRs and DVD players. Users can create their own device drivers (IR or RS-232) or go to the Extron Web site (www.extron.com)

    How the MLC 226 Series Controllers Work: MLC Components and Interactions Unlike the Extron MediaLink Controller (MLC 206 Series), the MLC 226 Series requires and uses event files to perform all functions except basic input switching and volume control. The event files define, monitor, and govern how an MLC 226 Series controllerworks.
