Standard Features
• IR and RS-232 ports for universal display device control — The MLC 52 has a
dedicated port for communicating with virtually any projector or display via infrared
signal. The MLC 52 RS models also have ports for unidirectional RS-232 wired serial
control. Projector control drivers can be downloaded from www.extron.com or can
be created using the MLC 52 configuration program.
• Discrete On and Off display device power controls — These controls simplify
system operations and eliminate the need for a handheld display or projector remote
control.
• Configurable, backlit buttons — The front panel buttons can be set up to control
display device power, volume, input selection, or any other IR or RS-232 command
function supported by the device. The buttons are backlit and can be custom labeled,
offering easy operation in low-light environments.
• Macro and toggle button modes — Each button on the MLC can be programmed
to send out up to four IR or serial commands. You can set each button to issue all its
commands with one press (macro mode) or to issue its commands one at a time, in
sequence, with each button press (toggle mode).
• Front panel configuration port — This RS-232 serial port enables advanced
configuration, driver downloads, and firmware updates to be performed from the
front panel without the need to remove the controller from its mounting. The optional
Extron configuration cable (part number 70-335-01) can be used to connect the
MLC 52 to the RS-232 port of the computer.
• Three configuration methods — The MLC 52 can be configured easily using the
following methods:
• IR learning — Allows the MLC 52 to be set up directly from the remote control
of the display device without the need for software.
• IR data transfer — Duplicates complete configuration information from one
MLC 52 model to another without cables or software.
• Configuration software — Combined with one of the many IR or RS-232
drivers that are provided with the controller on DVD or available on the Extron
website, the Extron MLC 52 Configuration Program provides fast and simple
setup.
