4-23 MediaLink Controllers • Serial Communication
Latched /Momentary — Contacts can be programmed to operate in one of
two ways: latching (brief contact) (press to turn on, press to turn off), or
momentary (timed) (press to turn on, timeout to turn off). If you select
Momentary, you can set the timeout period by using the slider bar.
NC (open), NO (closed) — Select the appropriate box to make the relay
normally closed or normally open.
Projector Comm — In this area you can set the communications protocol (baud
rate, parity, data bits) that is required by the projector.
Misc. Options — This section provides a way to send (or not send) commands
while the display is off or powering down or powering up, to mute/unmute
MLS switcher or projector audio, and to repeat power-down commands. If
the Repeat Power-Down box is checked and IR codes are stored for the
power-down command, the MLC will send out IR power-down codes twice.
For MLCs that have firmware version 1.04 and higher, if the Auto Onbox is
checked, the MLC sends a display power-on command when any MLC front
panel button is pressed.
Limit initial power-up volume — Here you can specify an attenuation level for the
initial audio volume when the display is powered on. If the Limit initial
power-up volume box is not checked (not enabled) or if the limit is set to
100%, the volume will not be limited (attenuated) when the projector/
switcher turns on.
Auto shutoff — If Auto shutoff is enabled, the controller monitors the time elapsed
since the last button press or knob rotation and sends a display power off
command (or that command and any other commands associated with the
Display Power button) after a set period of inactivity. That period can be
selected in fifteen-minute increments to be as long as 480 minutes (8 hours).
Reset to Factory Defaults —
Total Factory Reset (MLC + MLS)! is a global system reset that clears all
settings (including audio adjustments and IR and RS-232 commands and
drivers) in both the MLC and in an attached MLS switcher.
To reset the switcher only, manually press and hold the Menu and Next
keys on the front panel while connecting the switcher to an AC power
source.
Total Factory Reset (MLC only)! is a global reset that clears all settings
(including button configuration and IR and RS-232 commands and
drivers) in the MLC only. This does not affect the settings and
adjustments that are specific to an MLS switcher (audio adjustments, for
example).
Projector Volume Options —
Rate refers to the speed at which volume control commands are sent to the
projector or switcher. The fastest command-sending rate is 0, the slowest is 3.
If the MLC is set to control the projector’s audio volume instead of controlling
a MediaLink Switcher’s volume, select the settings here that match the
projector’s volume control settings. Some projectors use increment/
decr
ement commands to change the volume, some use a table of
predetermined levels. If the projector uses the table method of adjusting
volume, the number of steps used for volume adjustment is indicated in the
lower right corner. Refer to the projector’s manual or the display driver setup
document for details.
