PRELIMINARY
MLC 226 Series • Software-and Web Page-based Setup and Control
Noteworthy features
Several of the adjustments in this part of the program correspond to adjustments
that can be made via front panel controls. Below is a brief description of some
settings that are not accessible through the front panel.
Preset Volume Level — If you enable this feature, when the MLC is powered on
or when the display device (projector) is powered on, the output volume are
limited to a percentage of the maximum power output.
Power-up/Power-down Delay — Most projectors require a certain amount of
time during warm-up and cool-down during which they do not accept
commands. Using these slider bars you can specify the amount of time for
the MLC to wait between sending the projector a power-on or power-off
command and when the next action can occur or the next command can be
issued.
Repeat Power-Down — Some projectors (typically models that use IR drivers)
require the power-down command to be sent out again after a short pause
in order to confirm the request to turn off the projector. Enable this feature if
the equipment you are using requires the power-down command to be
repeated.
Send Channel IR/232 as Display Powers Up — This option causes the MLC to
send a command to the projector to switch to its appropriate input at the
same time it powers up.
Lockout I/O select while Display powers up/down — If enabled, this feature
locks input buttons that are part of the switching rotation (set up to trigger
input switching) while the projector warms up or cools down.
Hold Power-down button 2 seconds — To prevent turning the projector off
accidentally, you can enable this feature, which requires the Projector Off
button to be held down continuously for at least two seconds before the
MLC will issue the power-down command.
Minimum Delay between I/O presses — Sometimes pauses are required
between changes from one input to another so that the projector can adjust
to the new incoming sync signal. This feature lets you select a delay
between input changes of from 0 to 5 seconds in one-half second
increments.
