PRELIMINAR
Y
The buttons on the optional IR 402 remote duplicate the MLC’s front panel controls
and also those of a VCR and a DVD player for normal operation. The IR 402 can
also be used to control a MediaLink Switcher. The controller or switcher responds
to commands from the IR 402 remote as if the corresponding button or knob were
pressed or turned on the controller or switcher.
From a distance of no more than 30 feet and within 40° of the axis, the IR 402 sends
infrared (IR) signals to
• a MediaLink Controller via the controller’s front panel IR pickup device or the IR
pickup device of an optional IR signal repeater.
• a MediaLink Switcher via a connected IR signal repeater. The switcher can
receive signals from the IR 402 remote control only via an IR signal repeater.
N Setup operations cannot be performed from the remote control.
The IR 402 remote’s Display Power buttons, Display Mute buttons, and the VCR
and DVD control buttons will not function until they have been programmed using
GC version 2.2 or higher and uploaded into the MLC.
N Pressing the remote’s Display Mute On and Display Mute Off buttons sends the
1M and 0M SIS commands (respectively) to the MLC.
N To increase audio volume, press the Volume up (
^ ) button, rotate the MLC’s
Volume knob clockwise, or select a larger number in the Control tab of the
MLC’s embedded Web page.
IR commands are transmitted from the MLC’s Display RS-232/IR port and IR ports
(via IR Emitters or optional IR Broadcaster) when the corresponding button is
pressed on the remote or on the controller’s, SCP’s, or control module’s front panel.
Refer to the Control Modules User’s Manual.
Front Panel Security Lockout ( Executive Mode)
To prevent accidental changes to settings, the MLC features front panel security
lockout (executive) modes for disabling access to controls. When panel lockout
is enabled, no one can make changes using the buttons or volume knobs on the
MLC’s front panel, an IR 402 remote control, SCPs control pad, or control modules.
When the front panel is locked, functions and adjustments can be made only via
RS-232, Telnet, or Web browser control. The Simple Instruction Set (SIS
™ ) command
3X corresponds to this mode (see page 5 -10). For details, see chapters 4 and 5. The
only way to override a front panel lockout via the front panel is to enter a personal
identifi cation number (PIN) to unlock the panel, if conditions allow that.
Enabling and disabling front panel lockout via the embedded
Web pages and the front panel
When front panel lockout is enabled, if a button is pressed, the button fl ashes red,
but no change occurs. Nothing—not input switching, projector control, room
control, volume adjustment, or any other knob- or button-executable function—
results from front panel actions when lockout is active. Changes can still be made
via RS-232 or Ethernet (Telnet or Web browser) control.
Front panel lockout can be enabled/disabled using the embedded Web pages
whether or not a PIN has been set. However, a PIN must be set up before you can
enable or disable lockout using the front panel buttons.
