About this Guide
This setup guide describes the MLC 62 Series MediaLink®
Controllers and provides the procedures for getting started
using them. Setup instructions are provided for the MLC 62 D
(US model) and the MLC 62 EU (Europe model).
Throughout this setup guide, the terms "MLC" and "controller"
refer to either of the MLC 62 models.
About the MLC 62 Series MediaLink®
Controllers
The Extron MLC 62 Series MediaLink Controllers are panels
designed to control a wide range of smaller A/V systems in any
small classroom or meeting room. They act as extended remote
control panels, telling the display when to switch between its
various inputs.
The MLC 62 series provide universal control for a display’s
power, input switching, and volume control. For one-button
functionality, the MLC 62 controllers feature eight labeled
back-lit buttons. If desired, these buttons can be replaced
with buttons having different labels, also provided with the
controller. The buttons can be configured using the MLC 62
Windows®-based configuration software.
The MLC 62 is housed in a secure one-gang enclosure, which
can be mounted on a lectern, desk, wall, or electrical junction
box.
Differences between MLC 62 models
Both MLC 62 models have the same button functionality and
configuration software. The MLC 62 D is the US version of the
controller; the MLC 62 EU is the European version.
Both versions control devices via both RS-232 and IR. They
differ from each other in the following ways (see the illustrations
on the next page):
• The EU model is provided with a Jung frame and fits over
a standard one-gang EU junction box.
• The D model has a one-gang Decora® style faceplate. It fits
in a one-gang US junction box.
• Some side and rear panel connectors are located in
different places on the two models (see "Front and Right
Side Panels" in chapter 2, "Hardware Setup").

4. Unplug the MLC during lightning and thunderstorms or
when it will be unused for long periods.
5. For the installation to meet UL requirements and to comply
with National Electrical Code (NEC), the MLC must be
installed in a UL approved junction box. The end user or
installer must furnish the junction box; it is not provided
by Extron.
Panels and Connectors
Front and right side panels
Prior to use, the MLC must be configured using the
Windows-based configuration program. All front panel buttons
can be set up to issue control commands for devices such as
projectors, switchers, or motorized screens. (See chapter 3,
"Software Setup", to access this software.) The pre-labeled
button layout can also be changed. (See "Replacing buttons",
later in this chapter.)
Other controls are located under the wallplate of the MLC 62 D
and on the right side panel of the MLC 62 EU. To access these
controls after installation, remove the wallplate of the MLC 62 D
or remove the entire MLC 62 EU from the wall. (See "Accessing
Front and Side Panel Controls After Mounting", later in this
chapter, for the removal procedures.)

Button illumination
The front panel button illumination provides you with status on
what the MLC is doing. The buttons are lit while the MLC has
power. When a button has been pressed and is active or on, it
lights brightly. When a button is inactive or off, it is lit dimly.
When buttons are placed in a mode that groups them together
(for example, Input mode) only the button that is pressed lights
brightly. The other buttons in the group remain dim. (Refer to
the configuration software's help file for information on setting
button modes.)
