MLC 60 Series • Setup Guide

for the MLC 62 RS D, MLC 62 IR D, and MLC 64 RS VC D

The MLC 60 Series are keypad controllers for

use in classrooms and meeting facilities. These

products mount to decorator-style wallplates and

one-gang or two-gang junction boxes, and include

black and white color options. The controllers have

backlit soft touch buttons and can control common

AV functions, including power, input switching, and

volume. The MLC RS models provide RS-232 serial

and IR ports for universal display control. In addition,

a digital input and two relays are included for

monitoring and controlling other systems in the room.

The MLC 64 RS VC D has a volume control module

that lets you raise and lower the volume on an Extron

amplier with a remote volume control port, such as

the MPA 152 Plus or MPA 401. The MLC 62 IR D provides IR control only.

NOTES:

• Installation and service must be performed by experienced personnel only.

• Check that the installation meets the local and state regulatory requirements, including building, electrical, and safety

codes, as well as UL and ADA accessibility requirements.

• For installation, conguration, and operation details, see the MLC 60 Series User Guide, available at www.extron.com.

1. Prepare the installation site. The MLC 60 D models can be installed in a standard US one-gang or two-gang electrical

junction box or mounting bracket (“mud ring”).

a. Install the electrical box, following the instructions provided with it, or the provided mounting bracket.

ATTENTION:

• Ensure that the electrical 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 or mounting bracket.

2. Change the faceplate, buttons, and volume control knob as needed.

a. (MLC 64 RS VC D only) If changing the faceplate on the MLC 64 volume

control module, rst remove the volume knob (see Removing the Volume

Control Knob on page 4).

b. Remove the faceplate from the MLC module (see Removing the Faceplate on

page 4).

c. If desired, replace the buttons in the faceplate (see Replacing the Buttons on

page 4).

d. Reattach the faceplate as follows (see the illustration at right): Making sure that

both the MLC and the board are upright, line up the tabs at the top and bottom

of the faceplate with the slots on the board, and press the faceplate into the

board until the tabs snap into place. The pegs in the upper-left and lower-right

corners of the faceplate should be seated in the two diagonal holes on the MLC

board.

e. (MLC 64 RS VC D only) If changing the volume control knob, press the new

knob onto the spindle of the volume control module, making sure that the

spindle is turned all the way to the left and that the dot on the knob is aligned

with the bottom edge of the volume icon on the faceplate. Tighten the hex

screw by rotating it one-half turn clockwise.

3. Connect the cables to the 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.

• Relays port (RS models only) — The Relays port provides connections for two relays. Connect one or two devices

(such as a low-voltage controller and a motorized screen, shown in the example below) to this port. The relay ports are

normally open and rated for 24 VDC, 1 A (see the example below).

NOTE: If you are using both relay ports, connect the ground wires of both devices to common pin 3.

• Digital Input port (RS models only) — The Digital Input port enables you to connect a switch or sensor to control

other devices in the room that are connected to the MLC serial, IR, or relay ports. The port measures 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 measured as logic low, and a voltage above 1.5 VDC as 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 V pull-up 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 conguration procedures). To wire this port, see the example below.

Pin:

• Wire the volume control module (MLC 64 RS VC D only) —

Connect the remote volume control port of an Extron amplier to

the 3-pole captive screw connector on the rear panel of the MLC 64

volume control module, as shown at right. No software conguration

is required for this module.

In the illustration at right, GND = ground, VOL = Volume and mute

control, and 10V = 10 VDC reference voltage.

NOTES:

• Choose an Extron amplier that is capable of remote volume control and muting.

Not all Extron ampliers have remote volume control ports. The MPA 152 Plus or

MPA401 are examples of the type of amplier to use.

• The MLC 64 RS VC D is backwards compatible, able to control existing ampliers

and preampliers as well as new ampliers and preampliers.

• Models of the MLC 64 RS VC D with an E number before E30472 are not compatible

with newer amplier models. The E number is located next to the device serial

number.

• Use shielded cable for audio connections to avoid inducing noise.

4. Connect and apply power. Connect the included power supply to the MLC as shown below, then connect power to all

devices in the system.

5. Configure the MLC buttons and ports (see the MLC 55, 62 and 64 Series Conﬁguration Program Help File for the

procedures):

a. Load and install the conguration software from the Extron website.

b. Obtain device drivers. Drivers for the devices that will be connected to the MLC rear panel IR and serial ports can

be downloaded from the Extron website. You can also obtain them using the conguration software if an Internet

connection is available.

c. Connect the MLC to the computer, using a USB A to USB mini-B cable between the MLC front panel USB port and the

computer USB port. Alternatively, use an RS-232 cable to connect the MLC rear panel Host/Cong port to the computer

serial port.

d. Upload the conguration to the MLC.

NOTE: The volume control module of the MLC 64 RS VC D is standalone and requires no configuration.

6. Test the system to ensure that the MLC is functioning properly.

7. Mount the MLC to an electrical box or a mounting bracket.

• Secure the MLC unit into a mounted electrical box

using the provided screws in the oval slots at the

top and bottom of the unit (follow the instructions

provided with the electrical box), or

• Mount the MLC to a mounting bracket (see the

illustration at right). For the detailed procedure,

see the MLC 60 Series User Guide, available at

www.extron.com.

Removing the Volume Control Knob

1. Rotate the knob until the dot on the knob is aligned with

the bottom edge of the volume icon on the faceplate. The

notches in the edge of the knob and the notch in the edge

of the hole in the faceplate should be aligned, enabling

you to access the hex screw that holds the knob in place.

2. Insert the small Allen wrench (provided) into the opening.

3. Rotate the Allen wrench one-half turn counterclockwise to

loosen the hex screw, then lift off the knob.

Removing the Faceplate

1. Insert the at end of a small screwdriver into each of the holes at the top and

bottom of the faceplate.

2. Press each tab inward until the faceplate is released (see the illustration at right).

Replacing the Buttons

1. From the front of the faceplate, press the button membrane to be replaced backward through its slots in the

faceplate until it comes free. If replacing the faceplate, repeat this step until all the buttons are removed.

2. On the back of the faceplate, set the new button membrane at the desired location, with the two pegs in the

upper-left and lower-right corners of the membrane (shown at right) in the holes at opposite corners of the row.

Press the pegs and buttons of the membrane into the faceplate.
