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 have 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.
NOTES:
• Installation and service must be performed by authorized personnel only.
• For full installation, conguration, and operation details, see the product user guide, available at www.extron.com.
Installation Steps
1. Prepare the installation site.
The MLC 62 EU and MK controllers can be installed in
standard EU and MK one-gang electrical wall boxes:
a. Install the electrical box, following the instructions
provided with it.
ATTENTION:
• Ensure that the junction box is properly
grounded.
• Assurez vous que le boîtier d’encastrement
est correctement mis à la terre.
b. Prepare and pull the cables through the electrical box.
2. (Optional) Change the faceplate and buttons as needed.
a. Remove the faceplate from the MLC module as follows:
1. On the right and left edges of the faceplate are two pairs of slots,
into which two small tabs on either side of the MLC t. Insert the
at end of a small screwdriver into each side slot (as shown at
right) and press inward until the tab is released from its slot.
2. Lift the faceplate off the MLC circuit board.
b. If desired, replace the buttons in the faceplate as follows:
1. From the front of the faceplate, press the button membrane to
be replaced backward through its faceplate openings until it
comes free. If replacing the faceplate, repeat this step until all
the buttons are removed.
2. On the back of the faceplate, place the new button membrane
at the desired location, with the two pegs in the upper-left and
lower-right corners of the membrane in the faceplate holes at
opposite corners of the row (see the illustrations at right). Press
the pegs and buttons of the membrane into the faceplate.
3. Repeat step 2b as needed.

c. Reattach or replace the faceplate as follows (see the illustration at
right):
1. Making sure that both the MLC and the faceplate are upright,
hold the MLC with its circuit board against the back of the
faceplate, aligning the two tabs on each side of the MLC with
the two slots on each side of the faceplate.
2. Each tab has a ridge that must snap into a slot on the side of
the MLC. Press the MLC into the faceplate until the ridges on
all four tabs snap into place.
3. Attach the mounting bracket to the junction box.
a. Place the mounting bracket onto the electrical box, aligning the keyhole slots
in the bracket with the screw holes on the right and left sides of the box.
NOTES:
• Recommended: To keep the MLC securely in place and
prevent it from being easily pulled from its mounting, ensure
that the side of the bracket with the word “Front” engraved on it
faces out (away from the electrical box).
• To be able to remove the MLC easily from its mounting, attach
the bracket with Front facing inward (toward the electrical box).
b. Secure the bracket to the mounting surface, using two of the
included screws in the keyhole slots at the top and bottom
(see the illustration above right).
4. Connect the cables to the MLC rear panel ports. Attach the cables
and IR emitters to the rear panel of the MLC and to the display
device or switcher as required.
• Port A Com: Connect a display device or switcher to this
serial port to control the device via RS-232 (see the
illustration at right).
• Port B IR/S: Connect a display device, switcher,
or up to two IR emitters to this port (see the
illustration at right). You can congure this port
for either serial or IR communication using the
MLC 55, 62 and 64 Series Configuration
Program.
• Relay ports: The relay ports provide
connections for two relays. Connect one or
two devices (such as a low-voltage
controller and a motorized screen, shown in
the example at right) to this port. The relay
ports are normally open and rated for
24 VDC, 1 A.
NOTE: If you use both relay ports,
connect the ground wires of both
devices to common pin 3.

• Digital Input port (D IN) — 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 is
considered 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 congured with a +5 VDC
pull-up resistor for use with basic non-powered
switches. If the device being connected has its own power source, congure the port to disable the pull-up mode (see
the conguration program help le for port setup procedures). To wire this port, see the example above.
5. Connect and apply power.
Connect the included power
supply to the MLC Pwr connector
as shown at right, then connect
power to all devices in the system.
6. Connect the MLC to the computer.
Use either of the following methods:
• Connect a USB A-to-USB mini B cable
between the USB configuration port on
the MLC side panel and a USB port on your
computer as shown at right, or
• Wire an RS-232 cable to the provided 3-pole
connector and connect it between the MLC
Remote port and the computer serial port, as
shown below.

7. Configure the MLC buttons and ports (see the MLC 55, 62 and 64 Series Configuration Program Help File).
a. Load and install the conguration software to your computer from the Extron website.
b. Obtain device drivers. Drivers for the devices to be connected to the MLC rear panel IR and serial ports can be
downloaded from www.extron.com. You can also obtain them using the conguration software if an Internet connection
is available.
c. Upload the conguration 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.
a. Align the MLC wall frame to the mounting bracket, which you
attached to the mounting surface in step 3 (see page 2).
b. Holding the wall frame in place on the bracket, press the MLC into
the frame until the two tabs on either side of the unit snap into the
opening of the mounting bracket, holding the MLC in place.
Mounting the MLC 62 EU in a Raceway Using a Spacer (Optional)
If you are experiencing difculty with the MLC staying in place when installed in a cable raceway, this may be due to a gap
between the mounting bracket and the wall frame.
When this gap exists, the tabs on the sides of the MLC do not reach the mounting bracket and the MLC does not snap
completely into the bracket.
You can remedy this situation by installing a spacer (provided with the MLC) between the mounting bracket and the rim of the
junction box. The spacer is black plastic and has a slightly larger center opening than the mounting bracket.
To install the MLC in a raceway with a spacer:
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.
3. With the “Front” label facing toward you, place the mounting bracket onto the spacer so
that the screw heads pass through the two keyhole slots in opposite sides of the bracket.
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.
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.
8. Align the wall frame with the mounting bracket on the
mounting surface.
9. Press the MLC into the wall frame until the unit snaps into
place.
