introduction
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.
