Introduction
M L C 5 2
The Extron MLC 52 IR and MLC 52 RS Basic
MediaLink Controllers are economical control
panels ideally suited for classroom A/V systems.
Each model comes with a black and white
faceplate and offers IR control, while the MLC 52
RS also includes unidirectional RS-232 control.
By providing easy input selection, power, and
volume control, these controllers make classroom
A/V operations simple.
Consistent Control in Every Room
Each MLC 52 controller acts as an extended
remote control panel, providing user-friendly
control for a display’s power, volume, and
input selection. Because the MLC 52 IR and
MLC 52 RS offer a central point of control for
a display device’s key functions, they eliminate
the need for the display’s IR remote control,
making operations much more efficient. With the
MLC 52 IR and MLC 52 RS, there are no
misplaced remotes to search for, no confusing
menus to navigate, and no dead batteries.
No matter what brand of display is installed in
each presentation venue, the MLC 52 IR and
MLC 52 RS MediaLink Controllers always provide
a consistent control method from room to room.
Presenters with little or no training can walk into
any MediaLink equipped classroom and operate
the A/V system with minimal effort.
Configurable Buttons for Flexible
Control Options
No programming knowledge is necessary to
install MLC 52 MediaLink Controllers. The
four lower buttons on the MLC 52 IR and
MLC 52 RS default to Volume Up, Volume Down,
Select PC Input, and Select Video Input. Using the
intuitive setup software provided, these buttons
can be configured to send out any IR or RS-232
command supported by the display, making
it easy to customize the controller to meet the
needs of most single-display A/V systems. For
example, three of the four buttons could be
configured for input selection, with the fourth
button dedicated to video mute or auto image.
Each button can store up to four separate
commands, providing additional flexibility to
meet the specific control requirements for most
display devices. When a button is configured
for Macro mode, all of the stored commands
associated with that button are sent with a single
button press. In Toggle mode, the button steps
through a series of two, three, or four commands,
issuing a single command with each press of the
button.
Free Projector drivers
Extron creates and administers a wide selection
of commonly used projector control drivers. These
IR and serial RS-232 drivers allow MediaLink
Controllers to communicate with a display
device. They enable control of basic projector
functions such as power, input selection, and
volume adjustment. Go to the Extron Web site
at www.extron.com to download drivers for the
latest and most popular projectors.
Three Easy Ways to Configure
The MLC 52 IR and MLC 52 RS enable
integrators to choose any of three methods
when configuring the controllers. When used
with the supplied Windows®-based configuration
software, installation files can be saved and used
to duplicate additional MLC 52 models. The files
can also be archived for later use.
IR learning - Allows MLC 52 controllers to be set
•
up directly from the IR remote without the need for
software and a PC.
IR beaming - Quickly and easily duplicates
•
complete configuration from one MLC 52 model to
another without cables or software.
Extron’s easy-to-use configuration software -
•
Provides fast and simple setup via RS-232 when
combined with one of many IR drivers available on
the Extron Web site.
