Operation
Projector Control
The MLC 206 can control a projector or other display device by using 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 into the MLC.
• RS-232 command strings can be entered directly from a host computer using the
supplied Windows-based 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.
See chapter four and the MediaLink Control Program software for details on
setting up the MLC and for downloading, programming, or learning projector
control commands.
Projector control memory
Each time a new projector driver is downloaded into the MLC, all previously
downloaded drivers (IR or RS-232) and user-defined RS-232 commands will be
replaced (overwritten or deleted) by the new driver. Similarly, entering a user-
defined RS-232 command will cause the previously downloaded or user-defined
command to be replaced.
Secondary mode and special projector functions
The MLC has additional memory (up to 32 bytes per input selection button) for
storing commands for special projector functions such as zooming, focusing,
displaying color bars, or muting sound. These commands must be stored and the
MLC must be set up (see chapter four) to associate each command with a specific
input selection button. See the next page for LED and button names/numbers and
locations.
Follow these steps to execute the secondary mode commands:
1. Press input selection buttons three and four for three seconds to access the
secondary mode. The Display Power LED blinks rapidly while the secondary
mode is active.
2. While the secondary mode is active, press and release an input selection
button to send out the command that has been associated with it. The
button’s label blinks each time an input selection button is pressed and a
command is sent out.
The previously selected input remains active and will not change/switch while
the MLC is in the secondary mode.
3. To exit secondary mode, either press input selection buttons three and four
for three seconds and release them, or allow the MLC approximately ten
seconds of inactivity to time out to the regular (primary) mode.
Front Panel Features and Operation
Each of the front panel buttons can have more than one function. A button may
serve one purpose in regular use (in primary mode), but can have another function
that is accessible only when the MLC is in secondary mode. See
1 in the
following picture.
Many features must be set up in order to function. See chapter four, “Serial
Communication”, for information about the MediaLink Control Program,
which you must use to set up many features of the MLC 206.
