Operation
Projector Control
The MLC 52 IR models can control a projector or other display device by using IR.
The RS models can control a display device by IR or RS-232 control. The MLC
must be configured for projector control in one of the following ways before it will
send commands to the projector:
•
An IR or an RS-232 driver file can be downloaded from a disk or the Extron
Web site and used to configure the MLC.
•
RS-232 command strings can be entered directly from a host computer using
the supplied Windows-based configuration software (RS models only).
See chapter 5,
Serial Communications
, and the Windows-based configuration
software Help for details on setting up the MLC and for downloading,
programming, or learning projector control commands using the software.
•
IR commands can be entered directly from an IR remote control into the MLC
through IR learning. IR learning is convenient for installing new or updated
commands into the MLC in the field. It can be performed with or without the
use of software.
•
An MLC 52 can transfer/configure (duplicate or clone its configuration) to
another MLC 52 via IR data transfer without the use of cables or software.
Projector control memory
Each time a new projector driver is used to configure the MLC, previous
configurations are replaced (overwritten) by the new driver. Configurations are
stored in non-volatile memory. Therefore, if the power to the unit is interrupted,
the MLC retains its settings and configuration.
Front Panel Features and Operation
The MLC 52 front panel contains six buttons, each of which can be programmed
with up to four IR or RS-232 commands/functions. It also contains a configuration
port, through which the MLC 52 can be connected to a PC‘s RS-232 port to program
the MLC’s buttons, update firmware, and save the MLC’s current configuration to
the PC’s hard drive.
The two-gang sized MLC 52 IR VC and MLC 52 RS VC each have an integrated
volume control knob. This knob allows the two buttons normally used for volume
control on the standard, one-gang MLC to become available to control additional
outputs or other projector functions.
Buttons on the front panel
The front panel backlit buttons light amber when the MLC 52 is powered on.
Buttons that are not currently selected and active are lit more dimly (25%
brightness) than the selected ones (100% brightness).
When the MLC is delivered, the buttons are labeled. (You can relabel them by
replacing the labels with others provided with the MLC. See
Replacing button labels
in chapter 2,
Installation
.) You can program commands into these buttons (up to
four commands per button) using IR learning, the Windows-based control software
via the configuration port, or IR data transfer from another configured MLC 52.
Switch group
Some of the buttons are preconfigured to be part of a switch group. This means
that only one of the buttons that are in the switch group can be active at a time.
When one button is pressed and activated, it becomes fully lit, while the other,
inactive, button(s) are dimmed to 25% brightness.
