1 Input selection buttons and backlit labels — From
the upper left to lower right these buttons are
numbered 1 through 6. See chapter 2 for instructions
on how to replace the labels.
Basic operation — Press and release an input selection button to select the
designated input on the projector or the optional Extron switcher. All
labels are lit while the MLC receives power. The selected (active) input’s
label is lit more brightly than those of the nonselected inputs. If the
display power is off, the label backlighting will turn off (go dark) after a
period of inactivity (if no buttons are pressed for a while).
If the MLC is used without an optional switcher and the MLC has been
set up for use with a projector, only the number of inputs that are
available on the projector will be selectable on the MLC. If an optional
Extron switcher is connected to the MLC, all six input selection buttons
will be selectable. Which buttons are and aren’t part of the switching
rotation can be determined/set by the projector driver or via the
Windows-based setup program. See pages 4-7 and 4-12 and the
MediaLink Control Program’s Help file for details.
When an input selection button is part of the switching rotation,
pushing that button causes the MLC to send out an SIS input
change command via the MLS/Power connector
in addition to
sending projector control commands out the Display/Source
Control IR or RS-232 ports.
The standard Extron SIS commands sent
via the MLS/Power connector are fixed
and cannot be altered. The command for
each input is shown at right.
Additional and secondary functions —
IR/RS-232 command execution — Each input selection button can also
have IR commands or up to 32 bytes of RS-232 commands
associated with it. A command can be executed along with an
input switch by pressing the button while the MLC is in
primary mode. A different command can be executed by
