MLCPlus50/100/200 Series • Setup Guide
The Extron MLCPlus50/100/200Series MediaLink®Controllers with IP Link®Pro integrate Ethernet
connection into AV systems. This allows users to remotely control, monitor, and troubleshoot AV equipment,
including display devices and switchers. Each controller includes an embedded web server and support
for Power over Ethernet (PoE). It also includes ports for bidirectional serial control, IR output, relays, digital
input, and (except for the MLC Plus 50) volume control. Each MLCPlus is shipped with a mud ring.
• All models fit standard US junction boxes or mud rings.
• The MLCPlus100AAP and MLCPlus200AAP
also include space to mount from one to four
Extron AAP plates.
This guide provides instructions to install an
MLCPlus Series controller and to create a basic
configuration. Configure the controller using Extron
GlobalConfigurator®(GC) software running in
Global Configurator Professional (GCProfessional) or
GlobalConfigurator Plus (GCPlus) mode. The MLC
integrates with Extron GlobalViewer®Enterprise (GVE)
software and the GlobalViewer web-based AV resource
management for remote control applications. Global
Configurator and other useful software applications are
available at www.extron.com.
Installation
Step 1: Get Ready
Use the following check list to prepare for the installation.
• Download and install the latest version of the following:
• Global Configurator Professional or Global Configurator Plus software — for setting up and configuring the controller.
GC includes a link to the Toolbelt software and a way to upgrade the firmware of the controller. You must have an Extron
Insider account to use GC software. Contact an Extron support representative regarding training to use the full features
of GC Professional (see Locating Software, Firmware, and Driver Files on the Extron Website on page11).
• Toolbelt software — for setting up and configuring the controller
• IPLinkPro device drivers — for use with GC (Professional or Plus), to make control of other devices possible.
All are available from www.extron.com (see Locating Software, Firmware, and Driver Files on the Extron Website on page11).
• Obtain network information for the unit from the network administrator. You will need the following details for each MLCPlus device:
• DHCP setting (on or off) • Subnet mask • User name
• Device (MLC Plus) IP address • Gateway IP address • Passwords
• Write down the MAC address of each IPLinkPro device (such as the MLC Plus 50/100/200) to be used.
• Obtain model names and setup information for devices the MLC Plus 50/100/200 will control.
• Each controller comes with a factory-installed Secure Sockets Layer (SSL) security certificate. If you intend to install a
different SSL certificate, contact your IT department to obtain the certificate or for instructions on how to obtain one. See
“Secure Sockets Layer (SSL) Certificates” in the MLCPlus50/100/200Series User Guide for requirements and guidelines
regarding SSL certificates. IEEE 802.1X authentication is also supported once enabled (see “IEEE 802.1X Certificates” in the
MLCPlus50/100/200 Series User Guide for details).
Rev. D: Added

MLC Plus 50/100/200 Series • Setup Guide (Continued)
Step 2: Prepare the Installation Site
ATTENTION:
• Installation and service must be performed by authorized personnel only.
• L’installation et l’entretien doivent être effectués uniquement par un technicien qualifié.
• Extron recommends installing the MLC Plus into a grounded, UL Listed electrical junction box.
• Extron recommande d’installer le MLC Plus dans une boîte de dérivation électrique mis à la terre, certifiée UL.
• If the controller will be installed into fine furniture, it is best to hire a licenced, bonded craftsperson to cut the access
hole and perform the physical installation so the surface will not be damaged.
• S’il est prévu d’installer le contrôleur dans du beau mobilier, il est préférable de faire appel à un artisan autorisé et
qualifié pour couper le trou d’accès et réaliser l’installation de telle façon que la surface ne soit pas endommagée.
• Follow all national and local building and electrical codes that apply to the installation site.
• Respectez tous les codes électriques et du bâtiment, nationaux et locaux, qui s’appliquent au site de l’installation.
• For the installation to meet UL requirements and to comply with National Electrical Code (NEC), the MLC must be
installed in a ULListed junction box. The end user or installer must furnish the junction box. It is not included with the unit.
• Pour que l’installation respecte les exigences UL et soit conforme au National Electrical Code (NEC) américain, le MLC
doit être installé dans une boîte de dérivation certifiée UL. Il incombe à l’utilisateur final ou à l’installateur de fournir la
boîte de dérivation. Cet équipement n’est pas inclus avec l’unité.
Americans with Disabilities Act (ADA) compliance
When planning where to install the MLCPlus 50/100/200, you may need to consider factors affecting accessibility of the
controller such as height from the floor, distance from obstructions, and how far a user must reach to press the buttons. For
guidelines, see sections 307 (“Protruding Objects”) and 308 (“Reach Ranges”) of the 2010 ADA Standards for Accessible Design
available at http://www.ada.gov/regs2010/2010ADAStandards/2010ADAStandards.pdf.

Mud rings, optional ULListed junction boxes, external
junction boxes, and surface mounting boxes are
available for use with the MLCPlus. Read any installation
instructions and UL guidelines that come with the mounting
devices, protect the mounting surface to prevent damage,
then install the box or mud ring in the opening at the
installation site.
When you run cables to the mounting location, leave
enough slack for device installation. Secure the cables with
a clamp for strain relief so they do not slip back down into
the wall or furniture.
Step 3: Change a Faceplate
or Button Labels (optional)
Faceplates can easily be changed, if desired, and you can replace one or more of the labels within the buttons. Some button
labels ship with the unit. You can create and print your own customized labels using Extron Button Label Generator software.
Replacing a faceplate
To replace a faceplate:
1. Remove the faceplate by holding the body of the unit with one hand, gripping the sides of the faceplate with the other hand,
and pulling the faceplate away from the unit.

2. Align the openings of the new faceplate with the buttons and knob and with the LEDs and place the faceplate against the
unit. The magnetic catches fasten the faceplate onto the unit.
TIP: You can wait until the unit is mounted to the junction box or mud ring before placing the new faceplate on the unit.
Replacing button labels
You may wish to customize the button labels. The labels can be changed at any time. Follow these steps to change the button
labels:
1. Remove the faceplate as mentioned in step 1 of Replacing a faceplate.
2. For each button label to be replaced, use the provided Extron
removal tool to gently separate the clear button cap (lens) from
its white diffuser backing as follows: insert the end of the
removal tool into the corner notch and gently twist the tool.
3. Remove the label insert from the transparent button cap.
4. Select one of the button labels from the printed label sheets
included with the MLCPlus. Remove the label from its backing
and remove the clear, protective film from the front of the label.
5. Insert the button label into the button cap. Check for correct
label orientation.
6. Align the cap with the white diffuser and the panel opening, and
press the clear cap into place on the button.
7. Reattach the faceplate to the controller (see step 2 in
“Replacing a faceplate”at the top of this page).
Step 4: Cable All Devices
NOTE: Most examples on the following pages show the MLCPlus100. However, connector wiring and port functions
are identical for all models.
1. If the MLC Plus is not mounted to a grounded metal junction box or a grounded metal equipment rack, Extron recommends
connecting the unit to an earth ground to protect the unit from electrostatic discharge.
To ground the unit:
a. Securely terminate a grounding cable with
a ring terminal.
b. Remove the grounding screw in the
lower left corner of the rear panel, insert
the grounding cable, replace and securely
fasten the screw. Do not over-tighten the
screw. Maximum torque is 2 inch-pounds
(0.2 Newton-meter).
c. Connect the other end of the grounding
cable to an earth ground.

MLC Plus 50/100/200 Series • Setup Guide (Continued)
Step 5: Set up the MLCPlus for Network Communication
1. Connect the PC that you will use for setup and the MLCPlus to
the same Ethernet subnetwork. For LAN connections for the MLC,
see Control and power — LAN (Ethernet) and PoE on page6.
2. Start Global Configurator and use the Toolbelt feature of the
software (or use the stand-alone Toolbelt program) to set the
DHCP status or to set the IP address, subnet, gateway IP
address, and related settings. Network setup is essential prior to
configuration. Use the flowchart at right as a guide to setting up
the controller for network use.
NOTES:
• If using a host name instead of an IP address, the
user must enter a qualified host name
(Username.HostName.Domain).
For example: somename.somedomain.com.
• If using 802.1X security, see the Extron 802.1X
Technology Reference Guide and the Toolbelt Help file
for additional details on system setup.
Step 6: Configure the MLC Plus
The most basic steps are outlined below in the recommended order.
NOTE: See the Global Configurator Help File as needed for
step-by-step instructions and detailed information.
The help file for GC includes an introduction to the software,
and how to start a project and configuration.
1. Using GC, create a new GCPlus or GCProfessional project and configure the controller and any installed IP Link Pro
devices. The configuration tells the controller how its ports function; how to control other products; what to monitor; when to
do things; and whom to notify, how, and under what circumstances.
a. Configure ports on the controller.
• Select device drivers and link them to each assigned serial, IR, or Ethernet port.
• Configure settings (serial protocol, relay behavior, digital input, volume control settings) as needed.
b. Set up monitors, schedules, macros, and local variables.
c. Set up the front panel buttons: assign appropriate commands and actions, macros, timers, local variables monitors, or
feedback to the buttons.
2. Save the project.
3. Build and upload the system configuration to the controller.
Step 7: Test and Troubleshoot
1. Test the system.
• Press buttons and ensure the buttons light as desired and that the appropriate control commands or functions are triggered.
• Ensure that the audio output responds correctly to the volume knob or button. Also ensure
that the volume LEDs light correctly as you increase or decrease the audio gain.
• If the controller is connected to a network, ensure that the yellow Activity LED
and green Link LED on the LAN/PoE port light.
2. Make adjustments to wiring or configuration as needed. Remember that the
rear and side panel ports will not be accessible after the controller is mounted.
Step 8: Complete the Physical Installation
1. For AAP models, attach any optional AAP devices or blank AAP plates to
the metal AAP bracket as shown in figure 5 at right. Fasten the built-in
screws to the bracket with the provided nuts (hand tighten).
NOTE: You must purchase AAP devices and plates separately.
They are not provided with the MLC.
• Place the AAP devices as close together as possible.
Do not leave gaps between devices.
Open the Toolbelt software from within
Global Congurator (GC Professional
or GC Plus mode)
or as the stand-alone application.
Start Device Discovery.
Toolbelt displays a list of all Extron control
devices connected to the network.
Using the MAC address, locate the
desired device in the list and select it.
Enter credentials, if needed.
Network Communication Setup
Connect the controller and PC to the same
network. Apply power to all devices.
Use the Set IP feature in Toolbelt or
use the Toolbelt Manage > Network
Settings tab feature either to enable DHCP
or to enter the IP address or host name,
subnet address, and gateway, then congure
other network settings as needed.

• Place the AAP opening of the MLCPlus faceplate over the cluster of AAPs to check for correct fit. Make sure that the
edges of the AAPs all fit within the faceplate AAP opening so that no edges or corners catch or prevent the faceplate
from laying flat against the AAP mounting bracket. If needed, loosen the nuts, adjust the position of one or more AAPs,
and retighten the nuts.
2. For all models, follow instructions in “Mounting”, below.
Mounting
NOTE: Extron recommends taking safety precautions to avoid electrostatic discharge issues during installation.
Prior to mounting:
1. If it has not already been done, feed all device cables through the wall or furniture and, if applicable, through the plastic spacer.
NOTE: If the unit is not installed in a mud ring, you must install the plastic spacer. The spacer positions the unit to allow
the magnetic faceplate to attach properly and securely.
2. Ensure that cables are connected to the MLCPlus rear panel and to any AAP devices or plates.
3. Disconnect power at the source from all devices in the system.
Mount the MLCPlus as follows:
1. For AAP models, first attach AAP devices or blank AAP plates to the metal AAP bracket (see Step 8: Complete the
Physical Installation on page8.
2. For all models, insert the cabled MLCPlus into the mud ring or junction box within the wall or furniture, aligning the mounting
holes in the MLCPlus with those in box or mud ring.
3. For AAP models, fasten the MLC to the junction box, wall box or
surface mounting box, or mud ring as follows (see figure 7):
a. Insert screws through the mounting holes in the unit
or AAP bracket, then into the mud ring, or insert them
through the plastic spacer and into the wall box, and
loosely tighten the screws.
b. Align the faceplate with the MLCPlus and place
it against the front of the unit, allowing
the magnetic catches to fasten the
faceplate onto the unit. Check the
alignment and fit. The faceplate
must sit flush against the
front of the MLCPlus and
against the AAP bracket
without catching on any
LEDs, buttons, or AAP
edges, or on the edges of
the MLCPlus metal plate.
If the faceplate seats in
place correctly, remove
the faceplate, tighten the
screws, and reattach the
faceplate. The installation is
complete. If not, proceed
to step3c.
c. If necessary, remove the
faceplate, loosen the
mounting screws, and
adjust the position of the
MLCPlus, AAP mounting
bracket, or individual AAP
devices. Place the faceplate
over the unit to check the
fit, remove the faceplate, and
tighten the mounting screws once
all the elements are positioned to
allow correct alignment with the
faceplate.

4. For non-AAP models, secure the MLCPlus to the junction box, wall or surface mounting box, or mud ring as follows (see
figures 8 and 9):
a. Insert the included screws through the oval
slots at the top and bottom of the
MLCPlus, through the plastic
spacer (if not using a
mud ring), and into
the corresponding
threaded holes in the
box or mud ring.
NOTE: If the unit is
not installed in a
mud ring, you must
install the plastic
spacer. The spacer
positions the unit to
allow the magnetic
faceplate to attach
properly and
securely.
b. Using a Phillips
screwdriver, lightly
tighten the screws
until snug.

Reset Modes: a Brief Summary
The MLC Plus controllers offer the following reset modes:
• Use Factory Firmware: Press and hold the Reset button (located behind the faceplate) while applying power to the
unit. Keep holding the button down until the Reset LED blinks twice, or for 6 seconds, then
release the button. The control processor enters factory firmware mode. Use this mode to
temporarily revert to factory firmware in the event of a firmware failure.
Do not continue to operate the controller using the factory rmware version. If you want to use
the factory default rmware version, you must upload that version again.
• Project Recovery: See the MLC Plus 50/100/200 Series User Guide for instructions. Use this mode to recover the
project in the event of a lost user name and password.
• Run/Stop Program: Hold down the Reset button for about 3 seconds, until the Reset LED blinks once. Release
and press the Reset button momentarily (for <1second) within 1second. (Nothing happens if
the momentary press does not occur within 1second.) The LED blinks 2 times if the program is
starting. The LED blinks 3 times if the program is stopping. This mode allows you to restart any
scripts or events stopped by an IP settings reset.
• Toggle DHCP Client: Press the Reset button five times (consecutively). Release the button. Do not press the button
within 3seconds following the fifth press. Use this mode to enable or disable the DHCP client
for the LAN port.
• The Reset LED blinks 6 times if the DHCP client is enabled.
• The Reset LED blinks 3 times if the DHCP client is disabled.
NOTES:
• DHCP toggle mode is supported on firmware version 3.00.0000 or higher.
• By default DHCP is off and the unit uses a static IP address.
• When you disable DHCP, the unit uses the previous ly-set static IP address.
• Reset All IP Settings: Press and hold the Reset button for 6 seconds. After the Reset LED blinks twice, release and
momentarily press and release the Reset button within 1 second. Use this mode to reset all
network settings to factory default values without affecting user-loaded files.
• Reset All IP Settings: Press and hold the Reset button for 6 seconds. After the Reset LED blinks twice, release and
momentarily press and release the Reset button within 1 second. Use this mode to reset all
network settings to factory default values without affecting user-loaded files. This reset mode
also stops any running scripts and events and disables 802.1X authentication. Lastly, this mode
resets the settings for the LAN port, including turning DHCP off.
• Reset to Factory Defaults: Press and hold the Reset button for 9 seconds. After the Reset LED blinks three times, release
and momentarily press the Reset button within 1 second. Use this mode to return the controller
to factory default settings. This mode deletes all user-loaded files and configurations and it
clears messages in the event logs table. User-loaded digital certificates are deleted.
For detailed information on each mode and its use, see the MLC Plus 50/100/200 Series User Guide at www.extron.com.
