MLC 60 Series • Setup Guide
for the MLC 62 RS EU and the MLC 62 RS MK
The Extron MLC 62 RS EU and the MLC 62 RS MK
are keypad controllers for use in classrooms and
meeting facilities. The EU model attaches to a
single size European electrical junction box with a
60 mm mounting center; the MK model mounts to
a single size MK junction box. The controllers have
backlit soft touch buttons and can control common
AV functions, including power, input switching, and
volume. Both models provide RS-232 serial and IR
ports for universal display control. A digital input
and two relays enable monitoring and controlling
of other devices in the room. Both models have
six-button and eight-button options.

Digital Input port — Connect a switch
or sensor to this port to control other
devices in the room that are connected to
the MLC serial, IR, or relay ports. The port
monitors the high and low states of the
connection between the switch or sensor
and the connected device. For the voltage
thresholds, a voltage below 1.0 VDC is
considered logic low, and a voltage above
1.5 VDC, logic high. When a threshold
between the states is crossed (from high
to low and vice versa), the selected action
occurs.

By default, this port is configured with a
+5 VDC pull-up resistor for use with basic
non-powered switches. If the device being
connected has its own power source,
configure the port to disable the pull-up
mode (see the configuration program
help file for port setup procedures). To
wire this port, see the example above.

a. Load and install the configuration software to your computer from the Extron website or the provided DVD.
b. Obtain device drivers. Drivers for the devices that will be connected to the MLC rear panel IR and serial ports can be
obtained from the provided MLC software DVD or downloaded from the Extron website at www.extron.com. You
can also obtain them using the configuration software if an Internet connection is available.
c. Upload the configuration to the MLC.

8. Test the system to ensure that the MLC is functioning
properly.
9. Mount the MLC.
Before mounting the MLC to a wall or furniture, make
sure that all device cables are connected to the MLC rear
panel. Disconnect power at the source from all devices in
the system.

Mounting the MLC 62 EU in a Raceway
Using a Spacer (Optional)
MLC 62 RS EU
If you are experiencing difficulty with the MLC staying in place when installed in a cable raceway, this may be due to a gap
between the metal mounting bracket and the wall frame.
When this gap exists, the tabs on the sides of the MLC do not reach the metal mounting bracket and the MLC does not snap
completely into the metal bracket.
You can remedy this situation by installing a spacer (provided with the MLC) between the metal mounting bracket and the
rim of the junction box. This spacer appears very similar to the metal mounting bracket, except that it has holes instead of
slots for the mounting screws, is engraved with the words “Optional Spacer” and “Place behind bracket,” and has a slightly
larger center opening than the metal mounting bracket.
Raceway
1. Mount the electrical box in the raceway.
2. Attach the spacer to the electrical box by inserting two of the included screws in the
holes at the sides of the spacer. Leave the screw heads protruding approximately
1/8 inch from the surface of the spacer.
Junction Box
3. With the “Front” label facing toward you, place the metal mounting bracket onto the
Mounting Bracket
spacer so that the screw heads pass through two of the slotted holes in opposite sides
of the bracket.
NOTE: Ensure that the surface of the mounting
Spacer
bracket containing the word “Front” is
facing out (away from the spacer and
Junction Box
junction box).
Metal Spacer
4. Rotate the mounting bracket as necessary to ensure that
the MLC will be positioned straight on the mounting
surface and not skewed to either side.
Metal Bracket
5. Tighten the screws to secure the bracket to the spacer.
6. Pull the cables through the electrical box and the wall
frame.
7. Disconnect power from all devices at the source and
connect all cables to the MLC.
