MediaLink Controllers • Installation2-2

Installation Procedures

The MLC can be installed into a wall, a Euro Channel, or furniture, or, if an optional
faceplate is used, it can be mounted directly in furniture or an equipment rack.
Follow the instructions appropriate to the mounting option you have selected.
Templates for optional faceplates are not detailed in this manual.

Preparing the site and installing the wall box

Choose a location that will allow cable runs without interference. Allow enough
depth for both the wall box and the cables. You may need to install the cables into
the wall, furniture, or conduits before installing the controller.

The installation must conform to national and local electrical codes and to the
equipment’s size requirements. Dimensional drawings of the MLC 206 and
MLC 206 AAP and actual-size cut-out templates are provided in appendix B of this
manual. Templates for the optional faceplates are included with each faceplate.

Installation using a UL listed wall box is recommended for most mounting options,
but mud rings or a Euro Channel can be used instead.

• The MLC 206 includes a three-gang faceplate, the MLC 206 AAP includes a five­gang faceplate with space for Extron AAPs. Each can be installed in a standard
electrical wall box that is at least 1.75” deep. Mud rings are also available.

• The EC models (MLC 206 EC, MLC 206 AAP EC) can be installed in a standard
Euro Channel.

• Optional faceplates are available that accept the MLC 206 and also have openings
for Extron AAPs. Some optional faceplates can be installed into various sizes
of standard electrical wall boxes. Other optional faceplates are designed to be
directly mounted into a lectern or other furniture.

1a. If you are using a wall box or installing a MLC using a lectern mounting

faceplate, make a 100% size photocopy of the cut-out template that
corresponds to the faceplate you are using, and cut out the center portion of it
as indicated on the template.

1b. If you are using a mud ring, use the template that came with the mud ring.

Cut out the indicated center portion.

2. Place the template (or the wall box or mud ring) against the installation

surface, and mark the guidelines for the opening on the wall or furniture.

3. Cut out the wall/furniture material from the marked area.

4. Check the opening size by inserting the wall box, mud ring, or MLC into the

opening. The box or mud ring (if used) and/or MLC should fit easily into the
opening. Enlarge or smooth the edges of the opening if needed.

5. Feed cables through the wall box punch-out holes, and secure them with cable

clamps to provide strain relief.

6. Exposed cable shields (braids or foil) are

potential sources of short circuits. Trim back
and/or insulate shields with heat shrink.

To prevent short circuits, the outer
foil shield can be cut back to the point
where the cable exits the cable clamp.
Both braided and foil shields should
be connected to an equipment ground
at the other end of the cable.

The control modules are Architectural Adapter Plate modules that can be
connected to the MLC to control devices such as VCR, tape, or DVD players,
or provide limited control of an optional MLS 306/506 Series switcher, or
other devices. Up to four control modules (in addition to the IR Link) can be
connected to the MLC, though the connector can hold wires for only 2-3 items
at a time, so you may wish to daisy chain the control modules together.

You must also set the control modules’ rear DIP switches so each control
module has a unique address number.

Wire the MLC’s IR/RCM 3.5 mm, 4-pole direct insertion captive screw
connector as shown in the following illustrations. Refer to the Control Modules
User’s Manual or the Relay Control Modules User’s Manual for information on
setting an address for each device. An Extron Comm-Link cable (see
appendix A for part numbers) is recommended.

CAUTION

Polarity is important. If the IR/RCM connector wiring specified in the
diagram is not followed, the equipment may be damaged.

Connect a maximum of one (1) IR Link. Do not connect more than one
IR Link (either in parallel or in series). Also, do not connect more than four
(4) control modules to the MLC.

The MLC contains three relays, so you may install a maximum of one
RCM-SC or one RCM-SCLT in a system with an MLC.

The control modules are not hot swappable. When you add or remove a control
module, you must cycle (disconnect, then reconnect) the MLC’s power before
the MLC can recognize the new module and the configuration change.

Application diagram

An example of one way to connect accessories to the controller is shown in the
photo below. The Config port is not shown with an RS-232 cable attached because
that connection is only required during setup.

This system includes an MLC mounted in an optional faceplate (MLM-LAAP) that
holds two control modules (IRCMs, ACMs, and/or RCMs), and an additional
control module is connected to the upper IRCM and mounted in another location.
An IR Link infrared repeater shares the IR/RCM port with the control modules (a
much longer cable than the one shown here would be used). IR Emitters are
connected to the MLC for controlling a VCR, DVD player, tape player or other
source device, and/or projector. An RS-232 connection to the projector could be
made from the adjacent RS-232 Display/Source Control port. Note the wiring on
both ends of the cable that connects the MLC’s MLS/Power port to an MediaLink
Switcher (MLS).
