Input selection buttons
— These buttons can be used to select the desired audio
or video input for the connected device or for a variety of other functions. By default
the buttons are set up as follows:
•
MLC 62 RS models
— Three of these buttons are set to input mode, meaning
that they are a mutually exclusive group and only one of the buttons can be
selected (active) at a time. The active input button remains brightly lit, while all
other input buttons remain dimly lit. The fourth button, labeled
Mute
, is set in
Toggle mode and is not grouped with the others.
•
MLC 62 IR D
— Two double-sized buttons are grouped in input mode and are
mutually exclusive.
•
MLC 64 RS
— Four double-sized buttons are grouped in input mode and are
mutually exclusive.
You can change this button behavior by using the configuration software to change
the operating mode of the button (see the MLC 55, 62 and 64 Series Configuration
Program help file for more information).

and to update the firmware. This port can also provide power to the MLC during
configuration.

Do not use this port as the permanent power source for the MLC. It
should be used for power only during button and port configuration.

, the USB port is located at the right edge of the front
panel behind the wallplate. To access this port after installation, you must remove
the wallplate from the unit.
•
On the MLC 62 EU and MK
, the USB port is located on the left side panel. To
access this port after installation, you must detach the MLC from the installation
surface.
K
IR Learning sensor
— This sensor enables the MLC to learn IR commands from the
hand-held remote control of a display device or switcher. The IR-learned commands
are used to create an IR driver, then configured to be played back with any button
press (see
on page 33).
NOTE:
Before performing IR Learning to create a driver, check to see if an Extron
driver exists for your device (see
