MLC 226 IP Series • Setup Guide
The Extron MLC 226 IP Series MediaLink® Controller integrates Ethernet connection into
AV systems to allow users to remotely control, monitor, and troubleshoot AV equipment, including display devices and
switchers. It includes an embedded web server, multiple serial ports, relays, and configurable digital I/O ports for use in
applications that require control and monitoring of multiple devices within an AV system.
The MLC 226 IP series of controllers are configured using the free Extron Global Configurator (GC) software. The MLCs
integrate seamlessly with Extron GlobalViewer® Enterprise (GVE) software and the free GlobalViewer web-based AV
resource management software for remote control applications. Global Configurator and other useful software applications
are available at www.extron.com.
A checklist of basic setup steps is provided at the end of this guide. For additional information see the help files and the
MLC 226 IP Series User Guide, available at www.extron.com.

About Global Configurator (GC)
What It Does
Global Configurator is the software tool for setting up an MLC and the system it controls.
Global Configurator:
4
zz
Loads device drivers and uses commands from them for controlling other products
zz
Creates a single configuration file containing all the settings for the MLC and the products it interacts with in the AV
system
zz
Generates a graphical 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
By using GlobalViewer, users can manage, monitor, and control Extron and third-party equipment such as projectors,
displays, computer monitors, Blu-ray™ players, and DVD players.
What To Set Up in GC
Use GC software to create a configuration that tells the MLC how its ports will function; how to control other products;
which touchpanels to interact with; what to monitor; when to do things; and whom to notify, how, when, and under what
circumstances.
Configuration
1.
Download and install the latest versions of the following:
zz
Global Configurator software — for setting up the MLC and creating a single system configuration file
zz
Device driver package — for use with GC, to make control of other devices possible
All are avail­able from www.extron.com or on the included Extron Software Products Disc.
2.
Obtain IP address and subnet mask information for the MLC from the network administrator.
3.
Cable devices to the MLC (see”Cabling and Features” in this guide), then power on all the devices.
4.
Connect the MLC to a network, power it on, and use ARP (see “Network Configuration Using ARP“ below) to set the
IP address for the unit.
5.
Using Global Configurator, create a project, configure the MLC and other IP Link devices, and upload the configuration
to the MLC.
6.
Launch the GlobalViewer interface and test the configuration and the system.
NOTE:
Additional information and step-by-step instructions on configuration tasks are available in the Global Configurator
Help file. The Global Configurator Help file includes an introduction to the software and how to start a GC project.
Resources
Obtaining Control Drivers
Extron provides an extensive selection of device drivers in the driver package available on the Extron website.
If the system requires a control driver that is not part of the driver package, you have additional options:
zz
Request a new serial (RS‑232) driver from Extron.
zz
Create your own custom IR device driver using Extron IR Learner software. Follow the directions in the IR Learner Help file
to create a driver by using the remote control for that device and the IR receiver port on the front panel of the MLC.
Instructions, Information, and Assistance
For additional information see the help files and the MLC 226 IP Series User Guide, available at www.extron.com. If you have
questions during installation and setup, call the Extron S3 Sales & Technical Support Hotline or the Extron S3 Control Systems
Support Hotline.
Configuring for Network Communication
Network Configuration Options
When you power on the MLC for the first time, you have a choice of several ways to set up the IP address:
zz
zz
zz
zz
Use
Use
Use
Use
the ARP (address resolution protocol) command — See the instructions below.
a Web browser — See the MLC 226 IP Series User Guide.
the Global Configurator software — See the Global Configurator Help file.
SIS commands via Telnet — See the MLC 226 IP Series User Guide.
Network Configuration Using ARP
Use ARP to configure the IP address as follows:
1.
Obtain a valid IP address for the MLC from the network administrator.
2.
Obtain the MAC address of the MLC from the label on its rear panel. The MAC address should have this format:
00-05-A6-xx-xx-xx.
3.
Connect the PC and the MLC to the same subnetwork.
5
MLC 226 IP Series • Setup Guide (Continued)
4.
At the PC, access the command prompt, then enter
the arp –s command. Type in the desired new
IP address for the unit and the MAC address of the
unit (listed on the rear panel of the MLC). For
example:
arp –s 10.13.197.7 00-05-A6-03-69-B0
5.
Execute a ping command by entering “ping”
followed by a space and the new IP address at the
command prompt. For example:
ping 10.13.197.7
The response should show the new IP address, as
shown in the figure at right.
Mounting
Attach cables using the preceding pages
as a guide, then securely mount the
MLC and other devices into the wall
or furniture. Optional mounting kits
(see part numbers at right) are
available for use with the MLC. Read
the instructions and UL guidelines
that come with the any mounting kit
for installation procedures.

Setup Checklist: How to Proceed With Installation
Get Ready
Familiarize yourself with the features of the MLC 226 IP.
Download and install the latest version of the Extron Global Configurator (GC) software and the latest driver
package (avail­able from www.extron.com or on the Extron Software Products Disc.)
Obtain IP setting information for the MLC from the network administrator.
Obtain model names and setup information for devices the MLC will control.
Perform Physical Installation
Mount the unit.
Cable devices to ports on the MLC.
Connect power cords and turn on the devices in the following order: output devices (projectors, monitors,
speakers), the MLC, a PC (for setup), SCP panel (if desired), then all input devices (such as DVD players).
Configure the MLC
Connect the PC and the MLC to the same Ethernet subnetwork and use ARP via Telnet, Extron DataViewer, or a
similar application to configure the MLC for network communication.
Create a new GC project and configure the MLC. See the Global Configurator Help file.
Test the system.
If you have questions during installation and setup, you can call the Extron S3 Sales & Technical Support Hotline or the
Extron S3 Control Systems Support Hotline.
