About the MLC 52 Series MediaLink Controllers
The MLC 52 Series enable RS-232 or infrared (IR) remote control of a projector or other
display device. They are economical, compact (one-gang or two-gang size), easy-to-use
controllers for use with audio/video equipment in sites such as elementary or high school
classrooms or small conference rooms. The MLC 52 acts as a universal remote control
panel, providing control of the power, input selection, volume, and other functions of a
display device. Device control is provided via the MLC front panel buttons or via a host
computer or control system using RS-232 communication and the Extron Simple Instruction
Set (SIS
™
) commands or the Extron MLC 52/DVCM 50 Configuration Program.
The MLC 52 can be configured using three different methods:
• IR learning
• IR data transfer (“beaming”) from another MLC 52
• Using Extron device control drivers with the MLC 52 configuration software program
