Extron Electronics MLC 206 AAP EC User Guide - Manual (Page 45)

4-13 MediaLink Controllers • Serial Communication
Primary and secondary modes
The MLC Buttons area in the lower left of this screen lets you select between primary
and secondary modes. A button can have one code stored in its memory for
primary mode, and another code stored
for secondary mode. In each mode the
MLC’s buttons can be given an on-screen
label: select an option from the pull-down
menu above/below each button, as
shown at right. If desired, you can change
the label name during IR Learning or in
the Advanced Projector Config screen. In
normal use (primary mode), the MLC will
issue commands from its primary
memory blocks. Secondary mode is
typically reserved for special commands
such as auto adjust and zoom.
Display Power on/off
If you select Display Power, a dialog box appears in which you can select Power On
or Power Off so that the corresponding IR commands can be “learned” from the
projector’s remote control.
If the projector’s remote
control has just one
button for on/off
toggling, you must
“learn” that same
command to each button
(Display Power On,
Display Power Off).
Volume control settings
The MLC can control the audio volume adjustment of either an optional MediaLink
Switcher (MLS) or the projector.
Select Projector if you plan to use the projector/plasma display’s speakers or if you
plan to use the projector/plasma display as a preamp. Select Switcher if you plan
to use an external switcher as an audio preamp or amplifier.
If you select Projector, the Volume
Adjust dialog box appears, in
which you can select Up or Down
or Mute or Unmute so that the
corresponding IR commands can
be “learned” from the projector’s
remote control for controlling
these functions.
If you select Switcher, the MLC
will automatically issue the
necessary volume up/down
commands via the MLS/Power
port.
