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 to allow 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 for an experienced
installer 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12).
• 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12).
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.
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.

MLC Plus 50/100/200 Series • Setup Guide (Continued)
ATTENTION:
• 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.
NOTE: 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
MLCPlus50/100/200.
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. Or 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
translucent 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 on page2).
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).

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 IP address, subnet, gateway IP
address, DHCP status, 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.
NOTE: When setting up DHCP during network
configuration or if using a host name instead of
an IP address during project recovery, the user
must enter a qualified host name (HostName.
Domain).
For example: somename.somedomain.com.
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. Insert the built-in screws of the
AAP device through the holes in the metal AAP bracket and hand tighten to
fasten them to the bracket with the provided nuts.
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.
Connect the controller and PC to the same LAN and apply power.
Open the Toolbelt software or open the Toolbelt utility in
Global Congurator.
Use Toolbelt to display a list of MLC Plus units and all other
IP Link Pro devices connected to the network.
Using the MAC address, locate the desired device
in the list and select it.

• 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 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.

Reset Modes: a Brief Summary
The MLC Plus controllers offer the following reset modes:
• Use Factory Firmware: Press and hold the Reset button while applying power to the unit. Use this mode to temporarily
revert to factory firmware in the event of a firmware failure.
• 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.
• Toggle DHCP: 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 2.03 or higher.
• By default DHCP is off and the unit uses a static IP address.
• When you disable DHCP, the unit uses the factory default IP address
(192.168.254.250).
• 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 to Factory Defaults: Press and hold the Reset button for 9 seconds. After the Reset LED blinks three times,
release and momentarily press and release the Reset button within 1 second. Use this mode to
return the controller to factory default settings.
For detailed information on each mode and its use, see the MLC Plus 50/100/200 Series User Guide at www.extron.com.
About Global Configurator (with GC Professional and GC Plus Modes)
What the Software Does
Global Configurator Professional or Plus is the software tool for network setup and configuration of a MediaLink Plus controller.
Global Configurator:
• Loads device drivers for controlling and monitoring the status of devices within the AV system.
• Creates the configuration containing all the settings for the controller and the products with which it interacts in the AV
system.
• Generates a user interface called GlobalViewer that is uploaded to the MLC (a GlobalViewer host device) along with the
completed configuration and can be accessed as a Web page. Using GlobalViewer, users can monitor the MLCPlus.
Extron Control applications can also be used with the MLCPlus to permit remote control of the unit and, by extension, the Extron
and third-party equipment (such as switchers, projectors, displays, computer monitors, and DVD players) that the MLCPlus is
configured to control.
Resources
Obtaining Control Drivers
Extron provides an extensive selection
of device drivers available on the Extron
website. If the system requires a control
driver that is not already available, you can
request a new serial (RS-232), IR, or Ethernet
driver from Extron.
Obtaining Instructions, Information, and Assistance
A checklist of basic setup steps is provided in this guide. For additional
information see the help files and the MLCPlus50/100/200Series User
Guide, available at www.extron.com.
