Introduction
About the MLC 226 Series MediaLink™ Controllers
The Extron MLC 226 Series MediaLink™ Controllers are capable of controlling a
projector and various other items such as lights, a projector lift, or a screen motor.
Throughout this manual they are referred to as the MLC 226, MLC, or controller.
All models offer RS-232 and IR-based projector (display) control along with IR or
serial control of other devices (typically A/V input sources); relays for controlling
items such as a projector lift, motorized projection screen, and lights; and RS-232
remote control of an Extron switcher.
• The IP models can be configured and controlled either via RS-232 serial
• The non-IP models have nearly all the features of the IP models, but they can be

PRELIMINARY
Additional features for MLC 226 IP models
Via Ethernet/IP communication the MLC 226 IP models can make use of the
controller’s embedded Web pages, which include online diagnostics and
monitoring of basic control features. As an integrated part of the MLC 226 IP,
IP Link provides the following advantages:
Global compatibility — The switcher uses standard Ethernet communication
protocols, including ARP, DHCP, ICMP (ping), TCP/IP, Telnet, HTTP, and
SMTP.
Embedded Web page serving — The MLC 226 IP offers up to 7 MB of flash
memory for storing Extron and user-supplied Web pages, configuration
settings, and device drivers. Data in flash memory is served at a transfer rate
of 6 Mbits per second.
Multi-user support — Two hundred (200) simultaneous connections enable each
IP Link device to support many concurrent users and improve system
throughput by sending information in parallel.
Management ability via IP Link Global Viewer ver. 1.5 or later — The included
management application software allows you to control, monitor, and
schedule various functions of products connected to IP Link products.
E-mail notification — The MLC 226 IP can be set up to send an e-mail when the
projector has been disconnected or the projector’s lamp has been used for a
designated number of hours.
Controlling other devices
The MLC 226 Series offers two methods of projector and source device control:
RS-232 or infrared (IR). The MLC can learn IR signals from remote controls to
communicate with sources such as VCRs and DVD players. Users can create their
own device drivers (IR or RS-232) or go to the Extron Web site (www.extron.com)
to obtain device drivers.

How the MLC 226 Series Controllers Work:
MLC Components and Interactions
Unlike the Extron MediaLink Controller (MLC 206 Series), the MLC 226 Series
requires and uses event files to perform all functions except basic input switching
and volume control. The event files define, monitor, and govern how an MLC 226
Series controllerworks. Below are example diagrams of how the MLCs interact
with accessories, event scripts, drivers, ports, and input and output devices.

Introduction, cont’d
The MLC can be configured completely via the Windows-based configuration
software. Once you have set up how you want it to work (assigned drivers to
ports, configured buttons and relays, and set up IP addresses and functions), that
information is saved to a configuration file which is uploaded into the MLC.
The configuration information is used to create the “main event” (0.evt) script file
that defines the MLC’s operation. The main event file also controls and monitors
ports, optional SCP control pad(s), and changes made at the MLC’s front panel.
Each button on the MLC and on any connected SCPs, control modules (IRCMs,
ACMs, RCMs), or the IR 402 remote control has two switch numbers assigned to it:
one for the button press, one for release. Scripts are compiled to generate the main
event file to monitor any button press or release and to generate the actions (issuing
commands, triggering relays, switching inputs) associated with the buttons.

UL/Safety Requirements
The Underwriters Laboratories (UL) requirements listed below pertain to the safe
installation and operation of a MediaLink
1.Do not use the MLC near water or expose it to liquids.
To reduce the risk of fire or electric shock, do not expose this apparatus to
rain or moisture.
2.Clean the MLC only with a dry cloth.
3.Do not install the MLC near any heat source, such as a radiator, heat register,
stove, or another apparatus (including amplifiers) that produces heat.
4.Unplug the MLC during lightning and thunder storms or when it will be
unused for long periods.
5.For the installation to meet UL requirements and to comply with National
Electrical Code (NEC), the MLC must be installed in a UL approved junction
box. The end user or installer must furnish the junction box; it is not included
with the MLC.
Installing or Replacing Button Labels
For the MLC or the optional SCP control panel, 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:
™
Controller (MLC).
PRELIMINARY
1.Remove the button from the MLC or
SCP; use a small, flat bladed
screwdriver such as an Extron
Tweeker to gently pry a button out
from the front panel.
2.Locate the notch in the corner of one
side of the clear button cap.
3.Separate the white backing from
the clear button cap; insert the
blade of the small screwdriver into
the corner notch and gently twist
the blade.
4.Save the translucent, white
backing plate, but remove the
text/label insert from the
transparent button cap.
5.Select one of the button labels
from the printed label sheets included with the device (MLC or SCP).
Remove the label from its backing, if applicable.
6.Insert the button label into the button cap. Check for correct label orientation.
7.Align the white backing plate with the cap. The bumps on the backing plate
should be aligned (top and bottom) with the notches on the clear button cap.
Firmly snap it into place.
8.Align the tabs on the MLC with the notches on the backing plate. Gently but
firmly press the reassembled button into place in the MLC’s or SCP’s front
panel.
9.Repeat steps 1 to 8 as needed to relabel other buttons.

female, 9-pin HD connector. This connector also has one pin designated for
digital input/output.
RS-232 protocol:
• 38400 baud
• 1 stop bit
• no parity
• 8 data bits
• no flow control

The front panel 2.5 mm mini stereo connector Config port serves the same
RS-232 function as this rear panel port but is independent from it.
Both configuration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The configuration software
automatically sets the connection for the appropriate speed. If using
HyperTerminal or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.
Digital input: pin 1 and the ground pin together act as a digital input port
(depending on configuration). This allows for an additional way to trigger
events or functions (such as triggering relays, issuing commands, or sending
an e-mail).
Front panel Config port— This 2.5 mm mini stereo jack serves the same
2
RS-232 function as the rear panel Host Control port, but it is easier to access
than the rear port after the MLC has been installed and cabled. Digital input
is not available on this port. The optional 9-pin D to 2.5 mm stereo mini TRS
RS-232 cable (part #70-335-01, shown below) can be used for this connection.
This port has the same protocol as the rear panel port mentioned above but
does not offer digital input.
Both configuration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The configuration software
automatically sets the connection for the appropriate speed. If using
HyperTerminal or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.
Maximum distances from the MLC to the device being controlled may vary up
to 200 feet (61 m). Factors such as cable gauge, baud rates, environment, and
output levels (from the switcher and the device being controlled) all affect
transmission distance. Distances of about 50 feet (15 m) are typically not a
problem. In some cases the MLC may be capable of transmitting and
controlling a given device via RS-232 up to 250 feet (76 m) away, but the
RS-232 response levels of that device may be too low for the MLC to be able to
detect.

Projector control (Projector RS-232/IR) port (-5 VDC to +5 VDC) — Connect a
cable between the projector and the
left three poles of this 3.5 mm direct
insertion captive screw connector for RS-232 one- or two-way projector/
display control. Alternatively, the Tx/IR and Ground pins can be used for
one-way infrared signal output. From this port, commands from a projector
driver or user-defined command strings entered via the Windows-based
configuration program can be sent to the display device.
Connect a cable between the
right three poles of the Proj Cont port and
accessories such as an Extron Power Sensor. The Power Sensor can be used to
let the switcher know when the projector is on or off. If these pins are not
connected to a Power Sensor, the SNS and ground pins can be used for digital
input as can pin 1 and ground of the 9-pin D RS-232 Host Control port.
Digital input: pin 1 and the ground pin together act as a digital input port
(depending on configuration). This allows for an additional way to trigger
events or functions (such as triggering relays, issuing commands, or sending
an e-mail).

When configured as a digital input, this port will be in one of two states: 1
(on, high) or 2 (off, low). A closed circuit = a logic 1, an open circuit = a logic
0. Threshold voltages are <0.8 VDC = low, >2.0 VDC = high.
There is also a +5 VDC selectable pull-up resistor for this circuit.
Use the following illustrations as a wiring guide. Wiring will vary depending
on the projector model. In most cases the drivers are bidirectional, but
sometimes only the transmit (Tx) and ground connections will be needed for
projector control. For bidirectional RS-232 communication, the transmit,
ground, and receive pins must be wired at both the switcher and the projector.

Maximum distances from the MLC to the device being controlled may vary up
to 200 feet (61 m). Factors such as cable gauge, baud rates, environment, and
output levels (from the switcher and the device being controlled) all affect
transmission distance. Distances of about 50 feet (15 m) are typically not a
problem. In some cases the MLC may be capable of transmitting and
controlling a given device via RS-232 up to 250 feet (76 m) away, but the
RS-232 response levels of that device may be too low for the MLC to detect.

CM/IR/SCP port — You can connect up to four Extron control modules
2
(IRCMs, ACMs, RCMs), one Extron IR Link infrared signal repeater, and/or
an Extron SCP 226 control pad to this port to allow remote control of the
MLC 226 controller or other items. A maximum of six devices can be
connected to this port. Use the following diagram as a wiring guide.
The SCP 226 replicates the MLC’s front panel controls. The SCP 226 and the
IR Link can receive IR signals from an optional IR 402 remote control and
send them to the controller. Control modules can be used (once the MLC is
set up) to control VCRs, DVD players, tape decks, a projector lift, or screen
control. Refer to the appropriate device’s user’s manual.
The control modules, IR Link, and SCPs can be daisy chained, as shown in the
following diagram. Extron Comm-Link cable is recommended for these
connections.

The maximum total distance between the MLC 226 and a connected device is
200' (61 m).
This port provides up to 12 VDC for powering the SCP control pad or other
devices. The automatic current protection circuit for this port limits the draw
to 0.5 amperes.
If an IRCM/RCM/ACM is to be used in an MLC/SCP system, the control
modules connected to the SCP must be of the same kind/model and must be
addressed identically to the modules that are connected to the MLC. Refer to
the appropriate control module user’s manual for instructions on addressing
the control modules.
Any SCP control pad or control modules (CM, IRCM, ACM, RCM) used
with the MLC
will be affected by front panel security lockout (executive mode)
status changes.

IR/Serial Output ports — Depending on how the MLC is configured via the
4
configuration software, these ports output either infrared signals or
unidirectional RS-232 signals for controlling various devices such as VCRs
and DVD players. Before it can be used for controlling a device, each port
must be set up via the configuration software for either IR or RS-232
communication and associated with a device driver.
The connector pins are labeled S (signal) and G (ground).
For RS-232 output (-5 VDC to +5 VDC), use the illustration below as a wiring
guide, then wire a serial cable into this captive screw connector.

and ground. For specific information about wiring more than one IR Emitter
per port, refer to the Extron IR Emitter Installation Guide, part #68-808-01.
Alternatively, an Extron IR Broadcaster can be connected here if you need to
send out IR signals to a wider area than is possible for an IR Emitter. The IR
Broadcaster requires a +12 VDC power connection. The +12 V Out and
ground pins of the Projector port can be used to provide this power.

Projector Control
The MLC can control a projector or other display device by using IR or RS-232
control. The MLC must be configured for projector control in one of the following
ways before it will send commands to the projector:
• An IR or an RS-232 driver file can be installed from a disk or downloaded from
the Extron Web site into the MLC.
• RS-232 command strings can be entered directly from a host computer using the
supplied Windows-based software.
• IR commands can be entered directly from an IR remote control through IR
learning to create a driver that the MLC can use. IR learning is convenient for
installing new or updated commands into the MLC in the field.
See chapter 4 and the MLC 226/104 Configuration Program software for details on
setting up the MLC and for downloading, programming, or learning projector
control commands.
Front Panel Features and Operation
Many features must be set up in order for the MLC to function. See chapter 4,
“Software- and Web Page-based Setup and Control”, for information about the
MLC 226/104 Configuration Program, which you must use to set up most
features of the MLC.

Via the configuration software, other functions and relays can be associated
with each of these buttons.
Function/room control buttons and 3 input selection buttons — Each of
2
these buttons can be set several functions apiece, depending on how the MLC
is set up and what mode is active. Each button can be configured to control
the MLC’s relays, execute the IR or RS-232 commands of your choice, or
trigger event scripts and/or port monitoring.
The relays can be used to control items in the room such as a projector lift,
screen motor, or lighting. For details on how the relays operate and can be
configured, see the installation instructions in chapter 2 and the configuration
software information in chapter 4.
Function/room control buttons — These have the same

When these input selection buttons are configured for input
switching, there is a default 0.5 second delay between when one
input is selected and when a different input can be selected. This
allows time for the projector to adjust to the change of sync signals.
The delay period is adjustable.
If the MLC is used without an optional switcher and the MLC has been
set up for use with a projector, the selectable inputs on the MLC
correspond to the number of inputs available on the projector. If an
optional Extron switcher is connected to the MLC, all six input selection
buttons will be selectable. Which buttons are and aren’t part of the
switching rotation can be determined/set by the projector driver or via
the Windows-based configuration program.
When an input selection button is part of the switching rotation,
pushing that button causes the MLC to send out an SIS input
change command via the MLSRS-232
connector
control commands out the Projector
RS-232/IR port, triggering a relay, or
sending an IR or serial command via an
IR/Serial Out port.
The standard Extron SIS commands sent
via the MLS connector are fixed and cannot be altered. The
command for each input is shown at right.
Volume knob and LEDs — Rotate this knob to adjust the audio volume.
Volume can be adjusted via this front panel knob or via RS-232/Telnet/Web

this knob will control the projector’s audio levels or the optional switcher’s
audio levels. If the knob controls the projector’s audio levels, you can specify
incremental adjustments or range-based adjustments (via device driver only).
See chapter 4 and the MLC 226/104 Configuration Software Help file for
details.
If the MLC is configured for use with a MediaLink Switcher or for some

This port requires 38400 baud communication, a higher speed than many other
Extron products use. The MLC configuration software automatically sets the
connection for the appropriate speed. If using HyperTerminal or a similar
application, make sure the PC connected to these ports is set for 38400 baud.
Optional Control Modules and IR 402 Remote Control
The MLC can “learn” IR commands from a VCR’s, DVD’s, tape deck’s or other
device’s remote control, allowing you to create an IR driver file that can be
incorporated into the MLC’s event scripts. A command can be associated with each
of the buttons on an optional infrared control module (such as the Extron
IRCM-VCR, IRCM-DVD, IRCM-DVD+, IRCM-DV+, or IRCM-Tape) in order to
allow limited control of source devices. ACM control modules provide limited
remote control of adjustments to a slaved MediaLink Switcher (MLS).

The buttons on the optional IR 402 remote duplicate the MLC’s front panel controls
and also those of a VCR and a DVD player for normal operation. The IR 402 can
also be used to control a MediaLink Switcher. The controller or switcher responds
to commands from the IR 402 remote as if the corresponding button or knob were
pressed or turned on the controller or switcher.
From a distance of no more than 30 feet and within 40° of the axis, the IR 402 sends
infrared (IR) signals to
• a MediaLink Controller via the controller’s front panel IR pickup device or the IR
pickup device of an optional IR Link IR signal repeater.
• a MediaLink Switcher via a connected IR Link. The switcher can receive signals
from the IR 402 remote control only via an IR Link.
The IR 402 remote’s Display Power buttons and the VCR and DVD control buttons
will not function until commands have been stored in the MLC’s memory.
IR commands are transmitted from the MLC’s Projector RS-232/IR port (via hard
wiring) and IR ports (via IR Emitters or optional IR Broadcaster) when the
corresponding button is pressed on the remote or on the controller’s, SCP’s, or

PRELIMINARY
Software- and Web Page-based Setup and Control
An MLC 226 Series controller must be configured before use or it will not be able
to control other devices. The MLC 226 IP can be configured and controlled via a
host computer attached to the rear panel Host Control port or LAN port, or the
front panel Config port. See chapter 2 for pin assignments and other details on the
configuration and control ports.
• The primary means for configuring the controller is by using the supplied
software, which can also be used to control the MLC. This method requires a
properly configured PC with Windows
of Windows installed.
• Alternatively, the default Web pages embedded within the MLC 226 IP provide
a means to perform some setup, adjustment, and control via a Web browser
from any type of network-enabled computer.
• The third way to control and configure the controller is by using Simple
Instruction Set (SIS) commands via Telnet, a Web browser, or RS-232. SIS
commands are discussed in detail in chapter five.
Configuring the Hardware
To function together, both the PC and the MLC 226 IP must be configured
correctly. Unless you use an RS-232 connection for all setup and communication
with the controller, the PC must be network-capable with the proper protocols,
and the MLC 226 IP must be set up so it can be connected to a LAN (local area
network). Please note that some settings can be configured only via IP.
The first time you connect a PC to the controller via IP, you must temporarily
configure the PC to communicate with the controller Then you must change the
controller’s default settings (IP address, subnet mask, and [optional]
administrator name and password) in order to use the unit on an intranet (LAN)
or on the Internet (WAN). After you have set up the MLC 226 IP for network
communication, you can reset the PC to its original network configuration.
MLC 226 Series • Software-and Web Page-based Setup and Control
Both configuration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The MLC 226/104 Configuration
Program automatically sets the connection for the appropriate speed. If using
HyperTerminal or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.
Setting up the PC for IP communication
You need a Windows-based (Windows 2000, XP, or higher) PC equipped with an
operating network adapter. To allow your PC to work with Extron’s Ethernetcontrolled products, the TCP/IP protocol must be installed and properly
configured.
If you use an existing Ethernet LAN intranet, your network administrator can
provide you with a unique IP address for the controller or confirm whether you
need to set up the MLC 226 IP for DHCP (Dynamic Host Configuration Protocol) to
have an address assigned automatically when you sign on.
1.Open the Network Connections page as follows:
•Locate and right-click on My Network
Places on the Windows (2000, XP, or
higher) desktop, then click on
Properties.
or
•Click on the Start menu, click on Settings (if needed), click on Control
Panel, then double-click on Network and Dial-up Connections.
2.Right-click on Local Area Connection, then select Properties.
3.Select Internet Protocol (TCP/IP) and
click on the Properties button. If
Internet Protocol (TCP/IP) is not on
the list, it must be added (installed).
Refer to the Windows user’s manual
or the Windows online help system
for information on how to install the
TCP/IP protocol.

connector wiring. Plug the other end of the Ethernet cable into the Ethernet
port on the PC.
If a network hub or switch is used between the PC and the MLC 226 IP, use a
straight-through Category 5 cable instead of a crossover cable.
7.Set up the MLC’s IP address. See “Setting up the MLC 226 IP (at initial startup) for IP communication” below.
8.Restore the PC’s previous IP configuration by following steps 1, 2, 3, and 5 but
using the PC’s original IP address settings you wrote down in step 4.

MLC 226 Series • Software-and Web Page-based Setup and Control
Setting up the MLC 226 IP (at initial start-up)
for IP communication
When you power on the MLC 226 IP for the first time, there are three ways to set
up the controller’s IP address:
• Use the ARP command.
• Use a Web browser.
• Use the supplied configuration software.
Once the controller has been reconfigured, an Ethernet (intranet or Internet)
connection can subsequently be used to contact, configure, or control it.
Both your computer and the MLC must be connected to the same LAN.
Alternatively, you can use a crossover Ethernet cable to connect the controller
directly to your computer’s Ethernet card.
The following instructions assume that you have already configured the
Windows-based PC, connected it to the MLC 226 IP’s LAN port, and powered on
the controller.
Configuring the controller using the ARP command
You can use the ARP (address resolution protocol) command to set up an IP
address for the controller. The ARP command tells your computer to associate
the controller’s MAC address with the assigned IP address. You must then use
the ping utility to access the controller, at which point the controller’s IP address
is reconfigured.
Use ARP to configure the MLC 226 IP’s IP address as follows:
1.Obtain a valid IP address for the controller from your network
administrator.
2.Obtain the controller’s MAC address (UID #) from the label on its rear, top, or
side panel. The MAC address should have this format: 00-05-A6-xx-xx-xx.
3.If the MLC has never been configured and is still set for factory defaults, go
to step 4. If not, perform a Mode 4 system reset. For detailed information on
reset modes, see “Resetting the unit” in chapter two.
CAUTION
4.At the PC, access the MS-DOS command prompt, then enter the arp –s
command. Enter the desired new IP address for the MLC and the
MLC 226 IP’s MAC address. For example:
arp –s 10.13.170.15 00-05-A6-00-0A-90
The MLC 226 IP must be configured with the factory default IP address
(192.168.254.254) before the ARP command is executed, as described
below.
PRELIMINARY
MLC 226 Series • Software-and Web Page-based Setup and Control
The MAC address is listed on the controller’s rear or bottom panel.
After the arp -s command is issued, the controller changes to the new address
and starts responding to the ping requests, as described in the next step.
4-5
Software- and Web Page-based Setup and Control, cont’d
5.Execute a ping command by entering “ping” followed by a space and the
new IP address at the command prompt. For example:
ping 10.13.170.15
The response should show the controller’s new IP address, as shown
below.
You can reconnect using either Telnet or a Web browser to verify that the
update was successful.
6.After verifying that the IP address change was successful, enter and issue the
arp –d command at the DOS prompt. For example:
arp –d10.13.170.15 removes 10.13.170.15 from the ARP table
or
arp –d* removes all static IP addresses from the ARP table.
7.After configuring the controller, remember to change your PC’s TCP/IP
settings back to their original configuration.
PRELIMINARY
Configuring the MLC via a Web browser
The default Web pages that are preloaded on the MLC 226 IP are compatible with
the Internet Explorer Web browser (version 5.5 or higher).
1.Obtain a valid IP address for the controller from your network
administrator.
2.Launch the Web browser (Internet Explorer) on the connected PC (for which
you set up the network configuration earlier), and enter “http://
192.168.254.254/” in the address box. The MLC 226 IP’s default Web page is
displayed.
4.Select the Configuration tab, then select System Settings from the list/menu
on the left of the screen. A Web page appears. The top half of a typical screen
is shown below.
4-6
MLC 226 Series • Software-and Web Page-based Setup and Control
5.Enter the new IP address for the MLC the corresponding subnet mask, and
gateway address, then click on the Submit button. IP addresses, subnet
mask, and e-mail addresses follow standard naming and numbering
conventions/protocol. The IP network administrator should provide the IP
addresses and subnet mask to be used with this controller.
It takes a minute or so for the controller to store the new settings. (See “IP &
Email Config.” in the “Configuration Sortware for Windows” section of this
chapter for details about settings.) Once the controller’s IP address is
changed, you lose communication with the controller.
6.Close the browser.
7.After changing the controller’s IP settings, change your PC’s TCP/IP
settings back to their original configuration.
Configuring the controller via the MLC 226/104 Configuration Program
You can configure the controller via an RS-232 connection or an IP/Ethernet
connection if you use the Windows-based software.
1.Install the MLC 226/104 Configuration Program. See “Installing the
software” later in this chapter for details on software installation.
2.To run the program, double-click on the MLC

Windows-based software. Extron’s MLC 226/104 Configuration Program is
included with the controller, and updates can be downloaded from the Extron
Web site (http://www.extron.com).
Compatibility
The configuration software is compatible with Windows 2000 and Windows XP.
Do not run this software on a PC that uses an earlier version of Windows.
Installing the software
The configuration program is available at no charge via the Extron Web site. It
requires a minimum of approximately 25 MB (megabytes) of hard disk space. Plan
on having additional room available on the hard drive because you may add driver
and configuration files, event scripts, and user-created Web pages.
To install the software on the hard drive:
1.Locate and select the MLC 226/104 Configuration Program, the IR Learner
utility software, and Extron driver files from the Extron Web site.
The configuration software is designed for use with the MLC 226 Series and
MLC 104 Series controllers only, but the device drivers (for controlling
projectors, VCRs, DVD players, etc.) can be used by other Extron IP Link
products, so they may be listed as an IP Link driver file package.
2.Follow the onscreen instructions to download and install both programs
(MLC 226/104 Configuration Program, IR Learner) and the driver package.
By default the installation creates an “MLC 226” directory, and it places folders
(Drivers, IRLearner, MLC 226/104), icons and files for the MLC 226/104
Configuration Program, Help, Firmware Loader, IR Learner, and drivers into a
folder named “Extron” and a group named “Extron Electronics”.

CAUTION
Using the configuration program
Some items found in the configuration program correspond directly to the front
panel controls. (See chapter three for features/settings.) The Help program
provides information on settings and on how to use the configuration program
itself. Most features, particularly driver installation and controller and buttonconfiguration, are available only via this program. These features are described in
the sections of this chapter corresponding to the parts of the configuration program
where the features are found.
4-8
MLC 226 Series • Software-and Web Page-based Setup and Control
Do not change the directory or the name of the directory where these files
are installed by default.
The MLC can be set up to allow configuration access to administrators only,
and to prevent other users from making changes to the controller’s settings,
events, and drivers. If an administrator password is set for the controller,
non-administrator end users can select inputs and adjust output volume but
are prevented from making any other changes.
1.To run the program, double-click on the MLC 226/104
Configuration Program icon (shown at right) under the Extron
group or folder and the MLC 226 + 104 subgroup.
The Comm menu appears.
2.Select the COM port that is connected to the
controller’s Host Control port, or select IP (LAN) to
connect via an Ethernet network, as shown at right.
Click on the OK button. The Extron MLC 226/104
Configuration Program window appears. In the
following steps you will configure the controller
and optional equipment.
3.There are seven tabs within the software. During setup,
from the left tab (User mode) to the right tab (File Manager).
User Mode lets you perform basic control functions using a replica of the
front panel. It also lets you turn the relays on and off individually, and
allows you to set the front panel security lockout (executive modes).
Real-Time Adjustments is the page where you configure all audio levels
and settings and an assortment of other basic settings.
RS-232/IR Config. is where you set the communications type (IR/RS-232)
and protocol for each control output port (Projector port and the four
IR/Serial Out ports), then select the appropriate device driver for each
port based on the device connected to the port.
Button Config. is the tab for setting up every configurable button in the
system: MLC front panel Projector power, function/room, and input
selection buttons; buttons on all connected control modules (IRCMs,
ACMs, RCMs); and the buttons on the IR 402 remote control. On this
software page you select the driver commands, relay functions, internal
operations, or user-defined commands to be executed when each
button is pressed or released.
4.Before setting up the e-mail notification check boxes and the scheduling,
use the Build & Apply Configuration button or the option from the Tools
drop-down menu. This process builds, compiles, and stores in the
controller the event files it needs to operate. This step must be done prior to
starting the next step.
5.After performing the build and apply procedure, proceed to the next three
tabs (pages) of the program to finish setting up the controller:
IP & Email Config. shows all the IP-related settings. This is where you can
change the IP address of the controller, gateway, and mail server;
rename the unit; set system time; and set up e-mail notification options.
Scheduling is where you select the days of the week and times at which to
automatically turn the projector on and off.
File Manager displays the files currently stored in the MLC’s embedded
Web server and allows you to select files from that list to delete or to
work sequentially

download to the PC. It also offers an option for uploading a file from
the PC to the MLC. You probably will not need to use this part of the
program when you first set up the controller.
6.If desired, save the completed configuration to a folder (directory). The File
drop-down menu offers a Save CONFIGURATION to Directory… option for
this purpose. This is useful for backup purposes and also if you want to copy
the same configuration to another MLC.
Throughout the configuration program access to and ability to change/
configure most settings depends on whether you are logged in as a user or as
an administrator. By default there is no password, and everyone has
administrator access and privileges. Once an administrator password is set, a
user is able to view settings and select buttons/inputs but can change overall
volume only. All other settings may be changed by an administrator.
Drop-down menus
The menus available from the menu bar at the top of the configuration program’s
screen provide access to functions and information not found in other parts of the
software.
File menu
The File menu provides ways to access device driver and configuration files and to
save a configuration for future use.
PRELIMINARY
The File menu
Adding a new device driver to the MLC
1.Select Import DRIVER from…
2.Locate and select the driver file that is stored on the PC. RS-232 driver files
have filenames ending in .pke, and infrared driver filenames end in .eir.
3.Rebuild the list of device drivers that will be available to select from in the
RS-232/IR Config. page (third tab from the left). Rebuilding the driver list
makes the new driver available via the configuration program.
Rebuilding the list of available drivers
The Rebuild DriverBase option in the File menu lets you update the MLC’s list
of drivers that are available for use in the RS-232/IR Config. section of the
configuration program. This operation is automatically performed each time the
program is restarted.
Saving configurations
The MLC can be configured by various means (downloading settings, sending
SIS commands to the MLC, using the software tools), and the configuration
settings can be saved to a directory or folder for backup or for installation on
another MLC 226 Series controller. Saving a configuration is recommended
before you perform a firmware upgrade.
1.In the configuration program, select File, then select Save
CONFIGURATION to Directory… .

factory-set protocol used by the controller’s configuration ports.
• Projector lamp hours are a reflection of time elapsed since the lamp was
changed as determined by the driver scripts associated with the MLC’s
projector control port.
Setting and enabling PINs for front panel lockout (executive mode)
To prevent accidental changes to settings, the MLC features front panel security
lockout (executive) modes for disabling access to controls. When panel lockout is
enabled, the user cannot operate buttons or volume knobs on the MLC’s front
panel, an IR 402 remote control, SCPs control pad, or control modules. Functions
and adjustments can still be made only via the software or SIS commands via
RS-232, Telnet, or Web browser control. The Simple Instruction Set (SIS
command 3X corresponds to this mode. For details on how to lock and unlock
the front panel via the front panel buttons, see pages 3-7 and 3-8.
Before front panel lockout can be enabled via the MLC’s buttons, you must set up
personal identification numbers and enable them.
Set up the PINs and unit access via the PIN Manager feature in the Tools dropdown menu:

PRELIMINARY
1.Connect cables, power on the MLC and the host
computer, and start the configuration software.
2.Click on the Tools drop-down menu, and select PIN
Manager. A screen like the one shown at right
appears.
3.Click a radio button (Admin PIN Enabled or Both
PINs Enabled) to enable personal identification
number (PIN) use.
4.Set (type in) PINs. One PIN can be assigned for those
with administrator access, and another PIN can be
assigned for users. Each PIN must consist of four digits, each of which is a
number from 1 to 6. By default the Administrator PIN is 1346 and the User
PIN is 0000.
5.Click the Take button and close the PIN Manager.
6.Exit the configuration software, if desired.
When front panel lockout is enabled, if a button is pressed, the button flashes
red, but no change occurs. Nothing—not input switching, projector control,
room control, volume adjustment, or any other knob- or button-executable
function—results from front panel actions when lockout is active. Changes can
still be made via RS-232 or Ethernet control.
If PINs Disabled is selected via the PIN Manager drop-down box in the
configuration software, front panel lockout can’t be enabled/disabled by
anyone (with or without a PIN) via the front panel.

Updating MLC 226 IP firmware
If the need arises, you can replace the MLC 226 IP’s firmware without opening
the unit or changing firmware chips. To check which version of firmware the
controller is using, click on the Help menu. The firmware updating procedure
must be performed using a PC on which the MLC 226/104 Configuration
Software has been installed.
You may wish to save the existing configuration to a file (see page 4-10)
before replacing the firmware.
See appendix B, “Troubleshooting and Firmware Updates”, for instructions on
how to update the controller’s firmware.
Performing a master reset
The master reset function clears all event files; all projector drivers; and the
control module, IR, RS-232, audio, and other settings.
• If you select Master Reset (MLC) from the Tools menu, all settings are replaced
with the factory default settings; and all projector, port, and button
configurations are erased.
• If you select Master Reset (MLC & File System) from the Tools menu, not only
are the configurations erased and the MLC reset to factory defaults, but all the
installed files are erased from the MLC’s memory. This includes event files,
configuration files, and user-created Web pages.
Master reset does not remove any settings on the IP & Email Config. tab. A
connection between the PC and the controller should still exist after
performing a master reset.
Enabling/disabling switcher slaving
An Extron MediaLink Switcher (MLS) can be connected to the MLC to expand

Reflecting changes made via attached SCPs or control modules
By default the MLC’s front panel, an attached SCP panel, and the configuration
software’s User Mode tab all reflect the same settings and input selections. That
is possible because the “verbose” mode of communication is active: the front
panel, keypad(s), and software (via the PC) automatically notify each other of
changes. If you need to reduce network traffic or perform some types of
troubleshooting, you may wish to turn verbose communication off by deselecting

Noteworthy features
Several of the adjustments in this part of the program correspond to adjustments
that can be made via front panel controls. Below is a brief description of some
settings that are not accessible through the front panel.
Preset Volume Level — If you enable this feature, when the MLC is powered on
or when the display device (projector) is powered on, the output volume are
limited to a percentage of the maximum power output.
Power-up/Power-down Delay — Most projectors require a certain amount of
time during warm-up and cool-down during which they do not accept
commands. Using these slider bars you can specify the amount of time for
the MLC to wait between sending the projector a power-on or power-off
command and when the next action can occur or the next command can be
issued.
Repeat Power-Down — Some projectors (typically models that use IR drivers)
require the power-down command to be sent out again after a short pause
in order to confirm the request to turn off the projector. Enable this feature if
the equipment you are using requires the power-down command to be
repeated.
Send Channel IR/232 as Display Powers Up — This option causes the MLC to
send a command to the projector to switch to its appropriate input at the
same time it powers up.
Lockout I/O select while Display powers up/down — If enabled, this feature
locks input buttons that are part of the switching rotation (set up to trigger
input switching) while the projector warms up or cools down.
Hold Power-down button 2 seconds — To prevent turning the projector off
accidentally, you can enable this feature, which requires the Projector Off
button to be held down continuously for at least two seconds before the
MLC will issue the power-down command.
Minimum Delay between I/O presses — Sometimes pauses are required
between changes from one input to another so that the projector can adjust
to the new incoming sync signal. This feature lets you select a delay
between input changes of from 0 to 5 seconds in one-half second
increments.

Button Config.
The Button Config. tab shows and provides a way to set up all the available
programmable buttons of Extron devices that are part of the system:
• the MLC/SCP buttons (they are the same buttons and execute the same
functions)
• the IR 402 remote control’s buttons
• the buttons of any attached control modules (IRCMs, RCMs, ACMs)
In this part of the program you associate up to a total of six functions with each
button. You can select from driver functions, relay operations, button light
changes, delays between operations, digital output operations, and/or special
user-programmed commands. The options can be assigned in any combination.
Once the buttons are configured, this screen provides a way to check what type
of command or function, if any, is set for each button.
If logged in as a user rather than an administrator, you are not able to make
any changes to button configurations.

Configuring function and input buttons for tracking
The function and input buttons that are not part of the switching rotation can be
configured the same way the rest of the buttons can, but they also have an
additional option: tracking.
Tracking makes the function button’s light track (follow) the status of a function
(a relay, controller display mute, or audio mute). The button
lights when the selected function is on and goes dark/dim
when the function is off.
For example, if you set function/room button 2 to track (follow) the audio mute
status, the button lights bright amber when the audio is muted (via the software
or a 1Z SIS command), and it is dim amber when the audio is unmuted (via
software or a 0Z command).
The function/room button’s color cannot be changed from amber to anything
else if the tracking mode is enabled.

PRELIMINARY
Typical IP & Email Config. tab
Everything on this tab can be configured by an administrator with the exception
of the hardware (MAC) address, which is set by Extron and cannot be changed.
People with user access can see but not change items on the IP & Email
Config. tab. Only those with administrator access may change these settings.
IP addresses, subnet mask, and e-mail addresses follow standard naming and
numbering protocol. The IP network administrator should provide the IP
addresses and subnet mask to be used with this controller.
Extron Name/Descriptor is any name (e.g., Room104MLC226IP,
Lab1234mlc226IP, ConfRoomSystem, LectureHall8-cntrlr, etc.) you want to use
to label this specific MLC controller unit. The default is a combination of the
product name and part of the hardware address. This can be changed to your
choice of alphanumeric characters and hyphens (-).
• Spaces are not permitted within a unit’s name.
• Underscores (_) are not permitted.
• Valid characters are A-Z, a-z, 0-9, and - (hyphen).
• The name cannot start with a number or a hyphen, and it cannot end with a
hyphen.
• Maximum name length is 24 characters.
Local time is in 24-hour format.
The sync time to PC option sets the controller’s time setting to match that of the
computer on which the configuration program is running.
GMT is the time difference in hours between the installation site and Greenwich

Passwords are not required to operate the controller. However, you may wish to
limit access to controller setup by establishing an administrator password.
Only people with administrator access privileges are able to change the
settings (other than volume and input switching) and configuration of the
MLC controller. A password must consist of at least 1 and no more than 12
alphanumeric characters, which cannot include spaces.
If no password is set, everyone has administrator level access to the MLC. An
administrator password can be set without requiring a user password. An
administrator password must be established before the user password field is
made accessible.
Each password must consist of 1 to 12 alphanumeric characters without
spaces or symbols.
Passwords are also case sensitive. Also, passwords for the MLC can be as
short as 1 character. However, the MLC’s internal Web pages require a
password of at least 4 characters.
E-mail notification of status changes — The MLC can be configured to issue
notifications via e-mail when the projector has been disconnected or when a
certain number of hours of use has elapsed since the projector’s lamp was
installed/replaced. The lower half of this IP & Email Config. tab allows you to
enter the e-mail addresses of up to eight contacts for this purpose and to specify
which type of notice (projector disconnection or excessive lamp use hours) each
will receive. Follow the procedure below for e-mail configuration.
The e-mail notification settings (checkboxes/notification functions) are not
available via the MLC’s embedded Web pages.
If the projector/display driver selected for the projector port is a
unidirectional RS-232 driver, the Excessive Lamp Hours and Projector
Disconnected checkboxes also are not accessible or visible in the
configuration program. To monitor projector lamp hours and connection
status:
• The projector control port must be configured with a bidirectional driver.
• The projector must be able to report lamp hour status.
• The Projector On/Off buttons must be configured (via tab 4, Button

Only an administrator is able to make changes to the files stored on the
MLC. A person logged in as a user can view the list but not access or change
the files.
File types: a key to file names
You must have a basic understanding of the types of files used by this MLC
controller in order to decide what (if anything) to do with them.
___.eir — These are driver files containing infrared commands. There is a
separate ___.eir file for each device the MLC controls via infrared
communication. This is the type of file created during IR learning. Via the
configuration software, these files can be imported and associated with one
of the controller’s IR/Serial ports.
___.eml — E-mail template files have the .eml extension. These files are used to
generate e-mail messages such as those regarding projector disconnection
and excessive projector lamp hours. The first line of the file is the subject.
The rest of the file contains the body of the e-mail. For the MLC 226 IP, these
files are numerically named (1 through 64). For example, 1.eml, 2.eml,
3.eml,... 64.eml.
___.evt — These are event files, the most important files for the functioning of the
MLC. Almost everything the MLC does is coordinated by the scripts in the
4-38
MLC 226 Series • Software-and Web Page-based Setup and Control
main event file, 0.evt. The other event files perform device driver functions.
When the Windows-based configuration program creates event files, it
names (numbers) the files according to port associations. For example, the
main event file, 0.evt, contains instructions for the MLC’s internal
operations, while 5.evt is related to IR/Serial output port A.
CAUTION
________.pke — These are packages of Extron-created device drivers from which
event files are derived. These package files are not stored in the MLC, so
you do not see them in the file manager page. However, they are needed by
the PC during setup.
________.s19 — This is an Extron-supplied firmware update file. When the
firmware is replaced, the MLC is also automatically reset to factory default
settings. This file is not displayed on the file manager page. See appendix B
for details on firmware updates. Firmware can’t be updated by loading an
___.s19 file through the file manager.
MLC.cfg — This is a configuration file generated by the Windows-based
configuration program. It is a reference file used by the configuration
program, and its contents are also human-readable.
MLCmain.sc — This is the source code file generated by the Windows-based
configuration program. It is compiled to create the main event file (0.evt),
which directs all the actions and responses of the MLC.
File Manager buttons and when to use them
Delete Selected File(s) — Clicking on this button causes the selected file or files
to be removed from the MLC. This function can be used for removing files
loaded by the user.
CAUTION
Pick File(s) to Load to Server — Select this option only if a new file must be stored

This cable is recommended for connecting an MLC to an Extron MediaLink
Switcher and/or to an SCP control pad, an IR Link, or control modules such as
IRCM and RCMs:
10/100Base-T is Ethernet which uses unshielded twisted pair (UTP - Cat 5, etc.)
cable, where the amount of data transmitted between two points in a given
amount of time is equal to either 10 Mbps or 100 Mbps.
Address Resolution Protocol (ARP) is a protocol which assigns an IP address to a
device based on the device’s MAC or physical machine address.
Custom Web page is any file that can be loaded into an MLC 226 IP and served by
the switcher’s internal Web server. The Web page provides a way to control
the switcher and other devices attached to it without use of the software.
This is true with or without an accompanying event script. Any number and
size of graphics can be used, but if they are too large to fit in the MLC 226 IP’s
nonvolatile memory, you can create Web pages so that they can be served
from another Web server. If you install Microsoft Internet Information
Services (IIS) on your desktop, you can serve any page on its hard disk. The
MLC 226 IP functions like a little computer with a Web server—you can use it
for various Web-based tasks.
DHCP is the Dynamic Host Configuration Protocol (DHCP), a standardized
communications protocol that enables network administrators to locally and
automatically manage the assignment of IP addresses in an organization’s
network.
Driver is a package of commands that generates or is the event script that controls
devices.
Ethernet is a network protocol that uses MAC addresses instead of IP addresses to
exchange data between computers. Using ARP (see above) with TCP/IP
support, Ethernet devices can be connected to the Internet. An Ethernet LAN
typically uses unshielded twisted pair (UTP) wires. Ethernet systems
currently provide transmission speeds of 10 Mbps or 100 Mbps.
Event script is a program that runs on a MLC 226 IP and issues queries and
commands to the attached devices. Event scripts are written in the “Extron
C” language (.sc), and compiled into an event script (.evt). The Windowsbased MLC 226 IP control program performs this compilation. The compiled
result (.evt) is loaded onto the MLC 226 IP. The Extron C language is similar
to ANSI C, with some differences. As long as event scripts are turned on,
event scripts run continuously on the box.
HTTP is an acronym for the HyperText Transfer Protocol (HTTP), a Web protocol
based on TCP/IP, that is used to fetch HyperText objects from remote Web
pages.
IP (Internet Protocol) is the protocol or standard used to send information from
one computer to another on the Internet.
IP address is a unique, 32-bit, binary number (12 digit decimal number,
xxx.xxx.xxx.xxx) that identifies each device or device port (an information
sender and/or receiver) that is connected to a LAN, WAN, or the Internet. IP
addresses can be static (see static IP) or dynamic (see DHCP).
IP net mask/subnet mask is a 32-bit binary number (12 digit decimal number,
xxx.xxx.xxx.xxx) used on subnets (smaller, local networks) to help routers
determine which network traffic gets routed internally (within the
subnetwork) to local computers and which network traffic goes out to the rest
of the network or the Internet.
Media Access Control (MAC) Address is a unique hardware number given to
devices that connect to a network such as the Internet. When your computer
or networking device (router, hub, interface, etc.) is connected to a LAN or

the Internet, a table (see ARP) relates the device’s IP address to its
corresponding physical (MAC) address on the LAN.
Pass-through allows control systems to work with the switcher and provides a link
between two ports.
Ping is a utility/diagnostic tool that tests network connections. It is used to
determine if the host has an operating connection and is able to exchange
information with another host. The term (ping) is a reference to submarine
sonar, which sends out a signal and waits to hear it echo (“ping”) back from a
submerged object, much like how the ping utility functions in a network.
Port number is a preassigned address within a server that provides a direct route
from the application to the transport layer or from the transport layer to the
application of a TCP/IP system.
Static IP refers to an IP address that has been specifically (instead of dynamically—
see DHCP above) assigned to a device or system in a network configuration.
This type of address requires manual configuration of the actual network
device or system and can only be changed manually or by enabling DHCP.
Subnet See: subnetwork.
Subnet address The portion of an IP address that is specifically identified by the
subnet mask as the subnetwork.
Subnet mask A 32-bit address mask used in IP to identify the bits of an IP address
that are used for the subnet address. Using a mask, the router does not need
to examine all 32 bits, only those selected by the mask.
Subnetwork is a network that is part of a larger IP network and is identified by a
subnet address. Networks can be segmented into subnetworks to provide a
hierarchical, multilevel routing structure.
TCP (Transmission Control Protocol) is a connection-oriented protocol defined at
the Transport layer of the OSI reference model. It provides reliable delivery
of data.
TCP/IP (Transmission Control Protocol/Internet Protocol) is the communication
protocol (language) of the Internet. Computers and devices with direct
access to the Internet are provided with a copy of the TCP/IP program to
allow them to send and receive information in an understandable form.
Telnet is a standard terminal emulation utility/protocol that allows a computer to
communicate with a remote user/client. A user who wishes to access a
remote system initiates a Telnet session using the address of the remote client.
The user may be prompted to provide a user name and password if the client
is set up to require them. Telnet enables users to log in on remote networks
and use those resources as if they were locally connected.
