MLC 226 IP Series
Introduction
About the MLC 226 IP Series MediaLink™ Controllers
The Extron MLC 226 IP 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.
MLC 226 IP Series features
All models can be configured and controlled via a host computer using RS-232
communication or via IP Link™ Ethernet control. Setup and control can be
accomplished by simple ASCII commands (Simple Instruction Set, SIS™) or via the
included Global Configurator™ program. The software offers many more setup
options than does SIS programming.
PRELIMINARY
All models offer front panel controls. The optional IR 402 remote control and
optional SCP 226 Series hard-wired control pads can be used with the MLC, and
they mimic the MLC’s front panel controls. Additionally, the MLC 226 IP DV+
includes an IRCM-DV+ control module (for DVD and VCR control) installed in the
faceplate.
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 MLC 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 7.25 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 Global Configurator 2.2 and higher — The included
software and the GlobalViewer Web pages associated with it allow you to
control, monitor, and schedule various functions of products connected to IP
Link products such as the MLC.
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 IP 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 IP Series Controllers Work:
MLC Components and Interactions
Unlike the Extron MediaLink Controller (MLC 206 Series), the MLC 226 IP 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
IP Series controller works. Below is an example diagram of how the MLC interacts
with accessories, event scripts, drivers, ports, and input and output devices.

The MLC can be configured completely via the Extron Global Configurator
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 project file that 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, CMs, DVCM), 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.

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.
N Both configuration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The Global Configurator (GC)
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/output: pin 1 and the ground pin together act as a digital input/
output 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) that have been configured using GC.
Digital input: when this port is configured as a digital input, it is set to
measure two states: high and low. The threshold voltages are as follows: a
voltage below 2.0 VDC is measured as logic low, and a voltage above 2.8 VDC
is measured as logic high. There is also an internal, +5 VDC, selectable, pullup resistor for this circuit.
PRELIMINARY
Digital output — When this port is configured as a digital output, it offers
two output states: on and off. When the port is set to an “on” state, (the
circuit is closed), the I/O pin is connected to ground. Each I/O port is capable
of accepting 250 mA, maximum. When the port is set to the “off” state (the
circuit is open), the output pin is floating.
If the application calls for TTL compatibility, the circuit can be set up to
provide a 2k ohm pull-up resistor to +5 VDC.
b
Front panel Config (host control) port — This 2.5 mm mini stereo jack serves
the same 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. 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.

Use the following illustrations as a wiring guide. Wiring varies depending
on the projector/display model. In most cases the drivers are bidirectional,
but sometimes only the transmit (Tx) and ground connections will be needed
for projector/display control. For bidirectional RS-232 communication, the
transmit, ground, and receive pins must be wired at both the MLC and the
projector or display.

N Each projector or display may
require different wiring. For
details, refer to the manual that
came with the projector/display
or the Extron device driver
communication sheet.
N 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 MLC 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.
Digital input — The power sense (Pwr Sns) pin and the Ground pin together
can act as a digital input port if configured that way via Global Configurator.
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 is in one of two states: 1 (on, high) or 2 (off, low).
Threshold voltages are <2.0 VDC = low, >2.8 VDC = high.
Additional control connections
b
CM/IR/SCP port — You can connect up to four Extron control modules
(IRCMs, ACMs, RCMs, CMs), one Extron infrared signal repeater (IRL 20 or
IR Link), and/or up to two Extron SCP 226 control pads to this port to allow
remote control of the MLC 226 controller or other items. A maximum of seven
devices can be connected to this port.
The SCP 226 replicates the MLC’s front panel controls. The SCP 226 and
the IR signal repeater can receive IR signals from an optional IR 402 remote
control and send them to the controller. Control modules can be used (once
2-6
MLC 226 IP Series • Installation
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.
N If outside factors such as fluorescent light interfere with and affect the function
of the MLC, you can disable IR control of the MLC. Using a special function
SIS command (65#), you can turn off the MLC’s ability to receive IR signals
from IR signal repeaters and SCPs.
The control modules, IR signal repeater, and SCPs can be daisy chained, as
shown in the following diagram. Extron Comm-Link (CTL and CTLP) cable
is recommended for these connections. Use the following diagrams as wiring
guides.

IR/Serial Output ports — Depending on how the MLC is configured,
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 Global
Configurator software for either IR or RS-232 communication and associated
with a device driver.

For infrared (IR) output (0 to +5 VDC), wire an IR Emitter (2 emitters,
maximum, per port) as shown below for a modulated or demodulated signal
and ground. For specific information about wiring more than one IR Emitter
per port or about extending the length of the Emitter wires, refer to the Extron
IR Emitter Installation Guide, part #68-808-01.
N If installing two IR Emitters per port, wire them in series, not in parallel.
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 Display port can be used to provide this power.

Reset button and LED — Pressing this recessed button causes various IP
functions and Ethernet connection settings to be reset to the factory defaults.
See “Resetting the Unit,” in the next section of this manual, for details.
MLC 226 IP Series • Installation
Resetting the Unit
There are four reset modes (numbered 1, 3, 4, and 5 for the sake of comparison
with an Extron IPL product) that are available by pressing the Reset button on the
side panel. The Reset button is recessed, so use a pointed stylus, ballpoint pen, or
Extron Tweeker to access it. See the following table for a summary of the modes.
C
Review the reset modes carefully. Using the wrong reset mode may result
in unintended loss of flash memory programming, port reassignment, or a
controller reboot.
N The reset modes listed below close all open IP and Telnet connections and close
all sockets. Also, the following modes are separate functions, not a continuation
from Mode 1 to Mode 5.
Mode Activation
1
Hold down the recessed
Reset button while applying
power to the MLC.
After a mode 1 reset
is performed, update the
MLC’s firmware to the
latest version. Do not
operate the MLC firmware
version that results from the
mode 1 reset. If you want to
use the factory default
firmware, you must upload
that version again. See
appendix B, “Firmware
Updates,” for details on
uploading firmware.
Result
Purpose/Notes
The MLC reverts to the factory default
firmware. Event scripting will not start if
the MLC is powered on in this mode. All
user files and settings (drivers,
adjustments, IP settings, etc.) are
maintained.
Use mode 1 to revert
to the factory default
firmware version if
incompatibility issues
arise with
user-loaded firmware.
If you do not want to update
firmware, or you performed a mode 1 reset
by mistake, cycle power to the MLC to
return to the firmware version that was
running prior to the mode 1 reset. Use the
0Q SIS command to confirm that the
factory default firmware is no longer
running (look for asterisks following the
version number.)
3
Hold down the Reset button
for about 3 sec. until the
Reset LED blinks once, then
press Reset momentarily
(<1 sec.) within 1 second.
Mode 3 turns events on or off. During
resetting, the Reset LED flashes 2 times if
events are starting, 3 times if events are
stopping.
Mode 3 is useful for
troubleshooting.
4
Hold down the Reset button
for about 6 sec. until the
Reset LED has blinked
twice (once at 3 sec., again
at 6 sec.). Then press Reset
momentarily (for <1 sec.)
within 1 second.
Mode 4
• Enables ARP capability.
• Sets the IP address back to factory
default.
• Sets the subnet back to factory default.
• Sets the default gateway address back
to the factory default.
• Sets port mapping back to factory
default.
• Turns DHCP off.
• Turns events off.
Reset LED flashes 4 times in quick
succession during reset.
Mode 4 enables you
to set IP address
information using
ARP and the MAC
address.
5
Hold down the Reset button
for about 9 sec. until the
Reset LED has blinked three
times (once at 3 sec., again
at 6 sec., again at 9 sec.).
Then press Reset
momentarily (for <1 sec.)
within 1 second.
Mode 5 performs a complete reset to
factory defaults (except the firmware).
• Does everything mode 4 does.
• Resets almost all the real time
adjustments: all audio settings, limit
initial power up volume, power
up/down delay, auto power down, and
misc. options. This does not affect an
optional MLS switcher, however.
• Clears driver-port associations and port
configurations (IR/RS-232).
• Removes button configurations.
• Resets all IP options.
• Removes scheduling settings.
• Removes/clears all files from switcher.
The Reset LED flashes 4 times in quick
succession during the reset.
Mode 5 is useful if
you want to start over
with configuration
and uploading, and
also to replace events.

UL rack mounting requirements
1.
Elevated operating ambient temperature — If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient temperature. Therefore,
install the MLC in an environment compatible with the maximum ambient
temperature (Tma = +122 °F, +50 °C) specified by Extron.
2.
Reduced air flow — Install the equipment in a rack so that the amount of air
flow required for safe operation of the equipment is not compromised.
3.
Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4.
Circuit overloading — Connect the equipment to the supply circuit and
consider the effect that circuit overloading might have on overcurrent
protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
5.
Reliable earthing (grounding) — Maintain reliable grounding of rackmounted equipment. Pay particular attention to supply connections other
than direct connections to the branch circuit (e.g. use of power strips).
Mounting the MLC in a Euro Channel
1.
Remove the four faceplate attachment screws and remove the original
faceplate, if applicable.
2.
Attach the optional MLM 226 EC or MLM 226 AAP EC faceplate to the MLC
with the screws removed in step 1.
3.
With power disconnected at the source, insert the MLC into the Euro Channel.
For wider types of Euro Channels, you may need to insert a spacer plate first.

MLC 226 IP Series
Operation
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, downloaded from the
Extron Web site (www.extron.com), or downloaded from Extron using the driver
subscription feature within Global Configurator. The driver is saved to a folder
within C:\Program Files\Extron\Driver2, and it is uploaded to the MLC via
Global Configurator.
• RS-232 command strings can be entered directly from a host computer using
Extron Global Configurator software.
• IR commands can be entered directly from an IR remote control through IR
learning and the Extron IR Learner software 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.
PRELIMINARY
See chapter 4 and the Global Configurator help file or the IR Learner help file for
details on setting up the MLC and for downloading, programming, or learning
projector control commands.
Front Panel Features and Operation
N Many features must be set up in order for the MLC to function. See chapter 4,
“Software-based Configuration and Control”, and the MLC 226 IP Series
Setup Guide for information about Global Configurator, which you must use to
set up most features of the MLC.

MLC 226 IP Series • Operation
Each Display On/Off, Function/Room, and Input button can be set up to perform
several functions, which can be combinations of the following options:
• a driver operation—execute an RS-232 or IR control command that is part of a
device driver (for a projector, VCR, DVD, audio source, etc.)
• a relay operation—turn relays on or off, or toggle or pulse a relay
• a time delay operation—insert delays between executed commands
• a button light operation—change a front panel button’s brightness, color, or
flashing
• a digital input/output operation—turn the digital output on or off, toggle it, or
pulse it
• a user-defined RS-232 operation—issue a non-driver-associated RS-232
command (one that you programmed separately) via a specific port (IR/Serial
Out A, B, C; or the projector control port) or an internal command for the MLC,
itself
a
b
Display On/Off buttons — After they have been configured, press the On
button to turn the projector or display device on, and press the Off button to
power it off. By default, only one of these two buttons can be selected (active)
at once. Via Global Configurator (GC) software, other functions and relays
can be associated with each of these buttons.
c
Function/room control buttons and
input selection buttons — Each of
these buttons can be assigned 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
capabilities as the input selection buttons ( ), but are
typically used for triggering commands and functions other
than input selection. The F1, F2, and F3 buttons on the
optional IR 402 remote control correspond to these buttons. By
default these three buttons are each associated with a latching
relay, as shown at right. However, any software-based

N 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 buttons
are selectable. Which buttons are and aren’t configured for input
switching can be set via Global Configurator.
PRELIMINARY
N When an input selection button is designated for input switching, pushing that
button causes the MLC to send out an SIS input change command via the MLS
RS-232 connector. In addition it can make the MLC send projector control
commands through the Display RS-232/IR port, trigger a relay, or send an IR or
serial command via an IR/Serial Out port.
The default Extron SIS commands sent for each input via
the MLS connector are shown at right. If desired, you
can reassign (remap) any input from 1 to 99 to these
input buttons. Button remapping can be convenient if
an MLC is hosting a peripheral switcher.

Volume knob and LEDs — Rotate this knob clockwise to increase the audio
volume, counterclockwise to decrease volume. Volume can be adjusted via
this front panel knob, the corresponding knob on an SCP control panel, the
Volume up/down buttons on an IR 402 remote control, or via RS-232/Telnet/
Web browser control.
The Global Configurator software lets you select whether this knob controls
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
software’s help file for details.
N Not all devices that use RS-232 for audio level control can be properly controlled
using the MLC’s Volume knob. Some devices cannot respond quickly enough to
the commands issued to them by the MLC.
• If the projector uses range adjustments, that can result in choppy audio level
ramping (volume changing in jumps).
• If the projector uses incremental adjustments (volume up/down commands),
that can result in slow audio ramping (requiring many turns of the knob to
change the volume).
If you experience problems using range-based audio control with a projector or
other device, try slowing down the MLC’s volume knob command rate by using
the 49# SIS command (see page 5-39 for details) or encoder scaling in Global
Configurator (see page 4-14). If you need further assistance, contact Extron and
ask to speak with an applications engineer.

Config (host control) port — This is a front panel version of the rear panel
Host Control port (the 9-pin D connector), and it is independent of that port.
This port makes it possible to upload and configure device drivers and also to
initiate IR learning via a front panel connection after the MLC has been installed.
Connect a Windows-based PC or an RS-232 control system to this 2.5 mm
mini stereo-style (tip-ring-sleeve) connector. You can use the Extron 9-pin D

cable. See page 2-4 for a wiring diagram and port protocol.
N 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.
N Extron recommends configuring and controlling the MLC via the LAN
connector. Ethernet connections are faster and more reliable.
Optional Control Modules and IR 402 Remote Control
PRELIMINARY
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+, or IRCM-DV+) in order to allow limited
control of source devices. ACM control modules provide limited remote control
of adjustments to a peripheral MediaLink Switcher (MLS).
A total of four control modules (a maximum of four control
module addresses) can be installed with this MLC. Refer to the
Control Modules User’s Manual and the IRCM-DV+ Control
Module User’s Manual for installation details. See chapter 4 of

MLC 226 IP Series • Operation
IR 402
IR remote control
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 signal repeater.
• a MediaLink Switcher via a connected IR signal repeater. The switcher can
receive signals from the IR 402 remote control only via an IR signal repeater.
N Setup operations cannot be performed from the remote control.
The IR 402 remote’s Display Power buttons, Display Mute buttons, and the VCR
and DVD control buttons will not function until they have been programmed using
GC version 2.2 or higher and uploaded into the MLC.
N To increase audio volume, press the Volume up (^) button, rotate the MLC’s
Volume knob clockwise, or select a larger number in the Control tab of the
MLC’s embedded Web page.
IR commands are transmitted from the MLC’s Display RS-232/IR port 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 control module’s front panel.
Refer to the Control Modules User’s Manual.
Front Panel Security 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, no one can make changes using the buttons or volume knobs on the
MLC’s front panel, an IR 402 remote control, SCPs control pad, or control modules.
When the front panel is locked, functions and adjustments can be made only via
RS-232, Telnet, or Web browser control. The Simple Instruction Set (SIS™) command
3X corresponds to this mode (see page 5-10). For details, see chapters 4 and 5. The
only way to override a front panel lockout via the front panel is to enter a personal
identification number (PIN) to unlock the panel, if conditions allow that.
Enabling and disabling front panel lockout via the embedded
Web pages and the front panel
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 (Telnet or Web browser) control.
Front panel lockout can be enabled/disabled using the embedded Web pages
whether or not a PIN has been set. However, a PIN must be set up before you can
enable or disable lockout using the front panel buttons.

Configuration and Control: an Overview
An MLC 226 IP 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.
N Extron recommends configuring and controlling the MLC via the LAN
connector. Ethernet connections are faster and more reliable.
• The primary means for configuring the controller is by using the Extron Global
Configurator (GC) software. This method requires a properly configured PC
with Windows© 2000, Windows XP, or a higher version of Windows installed.
Global Configurator generates GlobalViewer™ Web pages that are uploaded
to the MLC and can be used to control the MLC and make adjustments to its
settings.
N Microsoft Internet Explorer is currently the only Web browser that supports
GlobalViewer pages.
PRELIMINARY
• 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
(Netscape Navigator version 6.0+, Internet Explorer version 5.5+, or Mozilla
Firefox version 1.0+) from any type of network-enabled computer.
N Netscape and Firefox cannot be used for viewing the Serial Control pages of the
factory-embedded Web page. Run Internet Explorer to use those pages.
• 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 5.

Control the MLC and devices connected to it by using the MLC’s embedded
Web pages or its GlobalViewer (GV) Web pages. See “Controlling the MLC,”
later in this chapter.
Configuring the MLC for Network Communication
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).
When you power on the MLC 226 IP for the first time, you have a choice of several
ways to set up the controller’s IP address:
• Use the Global Configurator software via an Ethernet connection.
• Use the ARP command with an Ethernet connection.
• Use a Web browser with an Ethernet connection.
If you use a Web browser or Telnet the first time you connect a PC to the controller
via IP, you must temporarily configure the PC to communicate with the controller.
See “Setting up the PC for IP communication with an MLC” later in this chapter.
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 IP’s RS-232 protocol:
•
•
•
•
•
38400 baud
8 data bits
1 stop bit
No parity
No flow control
N Both configuration ports require 38400 baud communication. This is a
higher speed than many other Extron products use. The Global Configurator
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.
MLC 226’s LAN port defaults:
• MLC’s IP address: 192.168.254.254
• Gateway’s IP address: 0.0.0.0
• Subnet mask: 255.255.0.0
• DHCP: off
• Link speed and duplex level: autodetected
Once the controller has been configured, an Ethernet (intranet or Internet)
connection can subsequently be used to contact, configure, or control it.
N 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 connected the Windowsbased PC to the MLC 226 IP’s LAN port or to the Host Control port or Config port,
and powered on the controller and the PC.
MLC 226 IP Series • Software-based Configuration and Control

PRELIMINARY
• Use SIS commands via an RS-232 connection, or Telnet with an Ethernet

Software-based Configuration and Control, cont’d
Configuring the MLC for network communication via Global
Configurator software
You can configure the controller’s IP address via an IP/Ethernet connection using
the Extron Global Configurator (GC) Windows-based software.
Read the Global Configurator help file for basic information on using
Global Configurator software and setting up a project. Also read the MLC 226 IP
Series Setup Guide, revision B or higher, included with the controller, for step-by-step
instructions of how to use GC to set up the MLC 226 IP’s IP address.
Configuring the MLC for network communication 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 (media access control) 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.
PRELIMINARY
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 2, “Installation.”
C
4.
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.
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 10.13.197.9 00-05-A6-00-9A-BB
N 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.
5.
Execute a ping command by entering “ping” followed by a space and the new
IP address at the command prompt. For example:
ping 10.13.197.9
You must ping the MLC in order for the IP address change to take place.
The response should show the controller’s new IP address, as shown in the
following picture.
4-4
MLC 226 IP Series • Software-based Configuration and Control

The default Web pages that are preloaded on the MLC 226 IP are compatible
with popular Web browsers such as Netscape Navigator (version 6.0 or higher),
Internet Explorer (version 5.5 or higher), or Mozilla Firefox (version 1.0 or higher).
However, the MLC and the PC must both be part of the same subnet before they
can communicate via the LAN port. You must change the PC’s IP address to one
that is on the same subnet as the default IP address of the MLC (192.168.254.254).
N This method requires a crossover cable. See page 2-14 for cabling details.

Setting up the PC for IP communication with an MLC
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.
When setting up the MLC for network communication via a Web browser or Telnet
connection, you must change the IP address of the PC to one that is on the same
subnet as the MLC. This is not required if you are setting up the MLC for network
communication via Global Configurator, the ARP command, or SIS commands via
an RS-232 connection.
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.

Global Configurator Software for Windows®
The included Extron Global Configurator (GC) program for Windows offers the
most complete way to configure and customize the controller via either RS-232
or IP connection. GC provides the ability to generate a Web browser-based
GlobalViewer™ (GV) application and Web pages for each IP Link-based device (IP
Link interface, System 5 IP, MLC 226 IP, MLC 104 IP, or other Extron device) on a
network. Once an MLC 226 IP is configured, its GlobalViewer Web pages allow the
user to manage, monitor, and control the MLC and the devices connected to it.
Global Configurator offers the best and easiest way to configure the controller.
Other setup options include using Simple Instruction Set (SIS™) commands and the
MLC’s factory-embedded Web pages, but many setup features are available only
via Global Configurator. GC includes some functions found on the controller’s
front panel and many additional features that are available only through the software.
Downloading the software and getting started
Global Configurator software is included with the controller. Global Configurator
software updates and a large variety of device drivers can be downloaded at no
charge from the Extron Web site (http://www.extron.com).
N Device drivers (for controlling projectors, VCRs, DVD players, etc.) can be used
by other Extron IP Link™ products, so they may be listed on the Extron Web
site as an IP Link driver package. You may also want to download the optional

A brief guide to Global Configurator’s tabs
In the upper right side of the GC software window are several tabs that divide
the program into groups of functions you can view and configure. The left three,
IP Link Settings, Schedule, and Monitor, are displayed for all IP Link-enabled
products. Any tabs to the right of those three vary in quantity, type, and layout,
depending on the product being configured. See the illustration below for an
example of the tabs that may be available when you configure an MLC.
IP Link Settings shows all the IP-related settings, as well as the unit part number,
MAC address and firmware version. You can view the IP address of the
controller and the unit administrator and user passwords here. However, the
IP address, passwords, and other items (gateway address, domain name, mail
server; unit name; system time, and the like) must be set by selecting Change
Device Settings from GC’s Tools drop-down menu.
Schedule is the tab where you select the days of the week and times for the MLC
to automatically turn the projector or other devices on and off, send e-mails, and
lock/unlock the front panel.
Monitor is the tab where you set up conditions/ports for the MLC to monitor. You
also use this part of the software to set up actions and configure appropriate
e-mails to send out in response to various conditions like projector disconnection
or excessive projector lamp hours.
Port Summary is an information-only tab. Click on it to display the following
items:
• names of the MLC’s ports (Display; IR/RS-232 output ports A, B, and C; and
MLS) or the devices connected to them

Display power up/power down settings (Power Settings)
All the settings in this section affect what happens during display power on/up
and power off/down cycles.
Auto shut-off period — This feature at the top of the Power Settings area lets you
set the length of time that
the display or projector can
be inactive before the MLC
automatically turns it off.
Settings can be 30 to 720
minutes or -- (0).

periods — The second
item in this area controls
whether and how long to
prevent (lock out) input
switching after an input
has been switched. This
delay can be set to 0 to 5
seconds in half-second intervals, and it is similar to special SIS command 54# on
page 5-40.

Most projectors do not accept commands during warm up and cool down
periods. The next two settings in this area specify the amount of time (0 to 300
seconds in 2-second intervals) for the MLC to wait between issuing a projector
power-on or power-off command and when the next input button press can
occur. These delays can also be set using special SIS commands (see pages 5-34,
and 5-39 through 5-40).
Repeat IR power down — Select this setting to have the MLC send out infrared
power-off commands to the display or projector twice in a row instead of once.
The MLC must be configured to send the IR power off command upon display
power off button release (not at the button press).
Send channel IR/232 as display powers up — Select this setting to make the
MLC send out commands associated with the currently selected input button
while the projector or display is powering on. Using this setting ensures that the
MLC’s and the display device’s inputs are coordinated.
Lockout I/O switching while display powers On or Off — To prevent users from
changing inputs during the entire power-on or power-off period, select this
setting.
PRELIMINARY
Hold power-down button
for two seconds — Select
this setting to require
users to press and hold the
Display Off button for two
seconds to start the display
power-down process.
This prevents users from
shutting down the display
or projector by accidentally
pressing the button.
Volume settings
When adjusting the volume, use — Volume control for a projector, display, or
audio output device involves one of two methods: selecting a setting within a
specific range of values, or sending a simple command to increase or decrease the
volume by a fixed increment. Select the appropriate method for the equipment
you are using. Refer to the user’s manual for the display or audio device.
If you choose Range, you can set the maximum quantity of volume change
steps. You can also set the specific level the audio output should not exceed
when the projector/display is powered on.
N The power-up volume limit is limited by the maximum volume setting (SIS
special command 47#). If the maximum volume (47# command) is set, the
limit audio level feature (SIS special command 11#) is automatically set to 25%
of the maximum volume (47#). See pages 5-34 and 5-39.
Volume encoder scaling factor (0-255) — This feature allows you to slow down
the volume knob (the encoder) on the MLC’s front panel. The value entered in
the encoder scale area is the encoder speed scaling factor. A value of 1 scales the
speed down by a factor of 2 (the MLC issues commands at 1/2 speed), a value of
2 scales by a factor of 3 (the MLC issues volume commands 1/3 speed), and so
forth. A factor of zero sets the MLC for no scaling: the volume encoder works at
full speed.
4-14
MLC 226 IP Series • Software-based Configuration and Control
This feature addresses a problem that occurs with some projectors that use
range type volume control. When the MLC’s knob controls projector volume,
sometimes the MLC sends the volume commands faster than the projector can
detect and process them. The projector does not detect some of the volume
change commands, resulting in a choppy volume ramp.
Encoder scaling gives the programmer the ability to slow the knob down to a
speed the projector can handle. The drawback is that users must turn the knob
more times to change from minimum to maximum volume. It is up to the user
to find a balance between smooth audio ramping and the number of knob turns
needed to cover the volume range. This requires trial and error for each projector
exhibiting this problem.
Although this feature is mainly for range type volume control, it applies to any
range type command programmed to be executed by the volume knob.
Digital input/output port 1 consists of pin 1 and the ground pin of the rear panel
Host Control 15-pin HD connector.
For digital I/O port 1, you can
choose one of the four options
(shown at right) for how the port
will function. See pages 2-3 to 2-4
for details on wiring and using this
port.
Digital input port 2 consists of the power sense (Pwr Sns) pin and the Ground pin
of the bottom panel Display RS-232/IR port. Because these pins can be used either
for digital input or for power
sensing, you must use this setting
in Global Configurator to select
between digital input and the
power sensor function. See pages
2-6 and 2-7 for details on wiring
and using this port.
Miscellaneous settings
In this area of the Advanced Configuration tab you can choose whether to reset

GlobalViewer™ Web Pages
The MLC 226 IP controller can be used as part of a network of devices based on
Extron IP Link™ technology, such as IP Link interfaces. Global Configurator (GC) is
a Windows-based program used for configuring and customizing the Web browserbased GlobalViewer (GV) application for each IP Link interface, System 5 IP,
MLC 226 IP, MLC 104 IP Plus, or other IP Link-based device on a network. Once an
MLC 226 IP is configured, its GlobalViewer Web pages allow the user to manage,
monitor, and control the MLC and the devices connected to it.
Refer to the Global Configurator help file and the MLC 226 IP Series Setup Guide for
specific information on how to use the software and perform basic setup tasks for an
MLC 226 IP.
N To work with Global Viewer Web pages, you must use Microsoft Internet Explorer
version 6.0 or higher with Active X enabled.

Customizing the MLC’s Control Web Pages
PRELIMINARY
Extron offers Web page templates that can be customized using standard HTML
editing tools to provide a different interface to the customer while still using
GlobalViewer functions. An experienced Web developer can add images, modify
text, and change background colors to create a look and feel that reflects your brand
or your user’s specific requirements. For example, a university with dozens of
devices and rooms to control may wish to create customized Web pages with the
university’s school colors and logo. End users can control the system using these
customized pages instead of the standard GV pages.
Alternatively, Extron can create a customized graphical user interface (GUI) for you
to upload to each MLC in the system. End users can view the Web pages of this
customized GUI while administrators and installers still have access to the factoryset Web pages and the standard GV Web pages in addition to the customized ones.
For a small, one-time fee, Extron will turn the following items into files ready to
upload to the MLCs:
• your Global Viewer project file containing system configuration details
• your choice of available color schemes
• your choice of labels for panel buttons
• a company or institution logo
These customized Web pages, whether created by Extron or modified by an outside
HTML developer from Extron-supplied templates, can also include button sets for
any control modules (IRCMs, ACMs, RCMs, CMs, etc.) used in the system.

Commands and Responses
PRELIMINARY
MLC 226 IP Series
SIS™ Programming and Control
The MLC 226 IP Series controller can be remotely set up and controlled via a host
computer or other device (such as a control system) attached to the rear panel
Config/RS-232 port or LAN port, or the front panel Config port.
The MLC 226 IP must be configured before use. As shipped the controller can
trigger basic input switching on an optional MLS switcher, but it cannot control any
other devices before being configured.
The MLC 226 IP can be set up and controlled by using Extron’s Simple Instruction
Set (SIS) commands or the Extron Global Configurator software (version 2.2 or
higher), and both of those methods can be accessed via RS-232 or Ethernet LAN
connection. See chapter 2, “Installation,” for pin assignments and other details on
the configuration and control ports. For information on the software and the MLC
226 IP’s embedded Web pages, see chapter four.
MLC 226 IP’s RS-232 protocol:
• 38400 baud
• 8 data bits
• 1 stop bit
• no parity
• no flow control
PRELIMINARY
N
Both configuration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The Global Configurator (version
2.2 or higher) 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.
LAN port defaults:
• MLC’s IP address: 192.168.254.254
• gateway’s IP address: 0.0.0.0
• subnet mask: 255.255.0.0
• DHCP: off
Host-to-MLC Communications
SIS commands consist of one or more characters per field. No special characters
are required to begin or end a command sequence. When the MLC determines
that a command is valid, it executes the command and sends a response to the host
device. All responses from the MLC to the host end with a carriage return and
a line feed (CR/LF = ]), which signals the end of the response character string.
A string is one or more characters.
MLC-initiated messages
If you are communicating with the MLC 226 IP via RS-232 or via a verbose Telnet
connection, when a local event such as a front panel selection or adjustment takes
place, the MLC responds by sending a message to the host. No response is required
from the host. The MLC-initiated messages are listed here (underlined).
ChnX!] (where X! is the input number)
The unit sends this response when an input is switched.

Vx.xx is the firmware version number.
The MLC sends the boot and copyright messages under the following
circumstances:
5-2
MLC 226 IP Series • SIS Programming and Control
• If the MLC is off and an RS-232 connection is already set up (the PC is cabled
to the MLC and a serial terminal emulation program such as HyperTerminal
is open), the connected unit sends these messages via RS-232 when it is first
powered on.
• If the MLC is on, it sends the boot and copyright messages when you first open
a Telnet connection to the MLC. You can see the day of the week, date, and time
if the MLC is connected via Telnet, but not via RS-232. If you are using a Telnet
connection, the copyright message, date, and time are followed by a password
prompt.
Additional messages may be sent by the MLC in response to front panel selections
and volume adjustments and when scripts are executed during scheduled events.
Password information
If the correct password is entered, the unit responds with “]Login Administrator ]”
or “]Login User]”, depending on the password entered. If passwords are the same
for both administrator and user, the unit will default to administrator privileges.
Error responses
When the MLC 226 IP receives a valid SIS command, it executes the command and
sends a response to the host device. If the MLC is unable to execute the command
because the command is invalid or it contains invalid parameters, it returns an
error response to the host.
The error response codes and their descriptions are as follows:
E01 – Invalid input channel number (the number is too large)
E12 – Invalid port number
E13 – Invalid value (the number is out of range/too large)
E14 – Not valid for this configuration
E17 – System timed out
E22 – Busy
E24 – Privilege violation
E25 – Device is not present
E26 – Maximum number of connections has been exceeded
E27 – Invalid event number
E28 – Bad filename or file not found
E30 – Hardware failure (followed by a colon and a descriptor number) (This is an
unsolicited response.)
Error response references
The following superscripted numbers are used within the command descriptions
on the following pages to identify commands that may respond as shown:
14
= Commands that give an E14 (not valid for this configuration) response if the
unit’s current configuration doesn’t support that command.
22
= Commands that yield an E22 (busy) response.
24
= Commands that give an E24 (privilege violation) response if you are not logged
in at the administrator level.
27
= Commands that may yield an E27 (invalid event number) response.
28
= Commands that may give an E28 (file not found) response.

Commands and Responses
Using the command/response tables
The MLC 226 IP can be controlled via either a Telnet (port 23) or RS-232 connection
using ASCII commands. Or it can be controlled via a Web browser (port 80)
connection using URL-encoded commands. The ASCII and URL commands listed
in the tables starting on page 5-8 perform the same functions, but they are encoded
differently to accommodate the requirements of each port (Telnet or browser).
The ASCII to hexadecimal
(HEX) conversion table shown
at right is for use with the
command/response tables.
ASCII to Hex Conversion Table
•
PRELIMINARY
ASCII to Hex conversion table
The command/response tables list valid ASCII (for Telnet or RS-232) command
codes, the corresponding URL (uniform resource locator) encoded (for Web
browsers) command codes, the MLC 226 IP’s responses to the host, and a
description of the command’s function or the results of executing the command.
• Upper and lower case characters may be used interchangeably in the command
field unless otherwise specified.
• Commands may be sent back-to-back without spaces (for example, 2!65V1Z).
• Numbers can be entered as 1, 2, or 3 digits, e.g., 8V = 08V = 008V.
• There are a few differences in how to enter the commands depending on whether
you are using Telnet or a Web browser.
5-4
•
When using these commands through a Web browser, the URL reference
is used to shorten the examples. “URL” refers to the full URL of the
control interface and Web page reference including all path information
(e.g., http://192.168.100.10/myform.htm).
•
To send any of the commands using a Web browser you must prefix them
with the full URL followed by ?cmd=.
•
For control via a Web browser, all non-alphanumeric characters must be
represented as the hexadecimal equivalent, %xx, where xx represents the
two-character hex byte. A comma (,), for example, would be represented
as %2C.
Characters such as %, +, and the space character ( ) must be encoded as
hex bytes, or they will be misinterpreted by the MLC. For example, the
ASCII command +V must be encoded as %2BV for Web browser use.
•
Some characters differ depending on the method you use to send the
commands:
Telnet
Web browser
Escape (hex 1B)
W [must not be hex encoded]
Carriage return (hex 0D)
Pipe character (|) [must not be hex encoded]
MLC 226 IP Series • SIS Programming and Control
With Telnet you can use either an “Escape” (E) command or a “W”
command, and the carriage return or the pipe character. With the Web browser,
you are required to use a “W” command and the pipe character.
N
In either method, {Data} = data that will be directed to a specified port
and must be hex encoded if non-alphanumeric.
If you make adjustments (changes to volume, etc.), whether via the front panel
or via RS-232 or IP communication, it will take 1 minute 40 seconds (100
seconds) for the data in the MLC 226 IP’s RAM to be saved to flash memory.

The current port timeout period applies
to the currently open Telnet session only.
When you start another Telnet session, it
uses the default global port timeout period.
X6( = timeout period in seconds. See
the description above. This variable is
applicable only when the MLC is connected
via Ethernet. If the MLC is connected via
RS-232 protocol, only the global timeout
commands apply, and any commands
involving X6( return the E13 error response.
The global port timeout is the default
timeout period for all Telnet sessions.
X6( = IP connection timeout period in
seconds. Each step is specified in 10-second
intervals (1 - 65000, default = 30 = 300
seconds). If no data is received during the
specified period, the Ethernet connection
closes. Responses are returned with leading
zeros.
This timeout period is applicable only when
the MLC is connected via Ethernet, and you
must be logged in as an administrator to
change this setting.

Additional description
N Verbose mode is a communication mode in which the device responds with more information than it usually would—more than the device, itself, requires. For example,
the controller can send out unsolicited information (such as notice of a volume or input change or a change in some other setting). That is an example of a verbose (wordy)
relationship between the controller and a connected device. Verbose mode creates more network traffic than usual, which can slow down network performance.
Verbose mode is usually enabled for troubleshooting and disabled for daily use.
• For a direct RS-232 connection, the controller is set for verbose mode by default.
• When the MLC is connected via Ethernet, verbose mode is disabled (by default) in order to reduce the amount of communication traffic on the network.
If you want to use the verbose mode with a controller connected via Ethernet, this mode must be set to “on” each time you reconnect to the controller.

N If you remap a port, you must set the port number to 1024 or higher, unless you reset the port to the default number or disable the port by setting it to 0.
For security reasons the network administrator may wish to assign new/different port numbers to the controller’s Telnet, Web browser, and direct access ports or to disable
one or more ports. Typically Telnet uses port 23, Web access is via port 80 (HTTP), and direct access is via port 2001.

actions and button presses. In response to a detected button press or other hardware happening, the event script can then tell the MLC to change relays, issue commands, or
make some other change. You would use this command only to associate a different event script file with tracking and responding to hardware/button actions.

By design an IRCM-DV+ can be assigned paired module addresses (by DIP switch) of either 1&2 or 3&4 only. It cannot
be assigned to addresses 2&3 or 1&4. The odd-numbered module address (1 or 3) is reserved for DVD control, the evennumbered module address (2 or 4) is for VCR control. The address DIP switches must be set in order for the MLC to
recognize and reserve memory space for the module. Refer to the Control Modules User’s Manual.

PRELIMINARY
To use an optional IRCM-DV+ with an MLC 226 IP, you need to associate the DVD portion of this module with an
MLC input selection butto, and also associate the VCR portion with a different MLC input selection button. The
associated button must be selected (pressed) in order to activate and use the VCR portion or the DVD portion of the
module. You cannot activate both parts (VCR and DVD) at the same time. If you do not associate (map) the IRCMDV+’s addresses (1&2 or 3&4) with MLC buttons, you cannot activate and use either the DVD or the VCR part of the
IRCM-DV+.
N For MLC 226 Series MediaLink Controllers, you can assign both the DVD and VCR portions of an IRCM-DV+ to the
same input selection button. A and B must both be inputs that are set up for input switching mode (firmware control)
via Global Configurator.

Button press/release emulation
Emulating a button press or release causes the commands and actions that are associated with the button via the main
event script to be executed. Button emulation triggers only what has been set up via the Front Panel tab in Global
Configurator. Emulation does not trigger the built-in SIS input switching commands (X20) !) or the projector power
on/off commands (1P or 0P).
See the diagrams below and on the next page to determine the number of the memory block associated with each
button.

This command tells the MLC to
repeat a specific button’s press
commands at a fixed interval (a

MLC 226 IP Series
Special Applications
There are numerous ways to use a MediaLink Controller to control and monitor
A/V systems. The MLC 226 IP Series Setup Guide and chapters 3 and 4 of this
manual cover typical uses and features. This chapter shows you how to set up the
MLC for a few specialized applications:
• tracking conditions by using monitoring
• working with DVD-VCR combination devices
• controlling multiple displays or projectors using the MLS peripheral port as
second projector port
• scheduling front panel lockout periods
• sending an e-mail by pressing a button on the front panel
• working with an Extron MPS 112 switcher
Using Monitoring to Make Functions Track Actual
Conditions
PRELIMINARY
If users have access not only to the MLC but also to the control panels or remote
controls of input and output devices, they can directly change various kinds of
device status and settings without using the MLC. This can create a discrepancy
between the device’s actual status and the status known to the MLC. To avoid that
discrepancy when configuring the MLC’s button functions and scheduling events,
you can set up a monitoring routine.
For example, let’s say that you set up an MLC front panel button (F1) in toggle
mode to send the projector a video mute command on one press and a video
unmute command on the next press. If you press the F1 button once, the MLC
sends the video mute command. The next time you press that button, the MLC
sends the video unmute command. But what if someone uses the projector’s
remote control to unmute the video before the next MLC button press? The MLC
issues a video unmute command when the F1 button is pressed, and the projector
continues displaying video — there is no change in mute status.
However, if, you also configure the MLC to check the projector’s A/V mute status
each time the F1 button is pressed, you can make the MLC act (or not) based on the
actual device status. That way, the MLC executes the correct action regardless of
what happened the last time the MLC’s button was pressed. This keeps the toggle
button synchronized with the status of the controlled device.
Prerequisite setup steps
1.
Connect cables between the MLC, the input/output devices, and the PC, as
described in chapter 2, “Installation.”
2.
Install and start the Global Configurator software and create or open a GC
project, and add an MLC to the project, if that hasn’t already been done. For
instructions, refer to chapter 3 of the MLC 226 IP Series Setup Guide, steps 1, 2,
and 3.
3.
In Global Configurator, add device drivers and assign them to the Projector
RS-232/IR port or MLS port. For instructions on these tasks, refer to
chapter 3, step 5, of the MLC 226 IP Series Setup Guide.
N For monitoring, the device must be connected to one of the MLC’s bidirectional
ports.

Working With Combination Source Devices
Many combination DVD-VCR players can output the video signals from both the
video tape and the DVD parts on a single port. If you connect this single output
to one input on a switcher (or projector), the switcher has no way to automatically
know whether it receives input from the DVD or from the VCR; the switcher treats
it as one input device and does not switch between the two.
Available methods
There are several ways to work around the single-input limitation to make both the
DVD and VCR media accessible to the switcher, including the following methods:
• Using separate source output ports on the DVD-VCR player
• Using a distribution amplifier with the switcher
• Using an IRCM-DV+ control module for DVD-VCR control
Using an IRCM-DV+ control module and one MLC input button
for DVD-VCR control
If the combination DVD-VCR player has only one available output port and
neither a distribution amplifier nor a pair of control modules [(IRCM-DVD or
IRCM-DVD+) and IRCM-VCR] is available for use, you can create a special
configuration to allow control via the MLC 226 IP or SCP 226 front panel and an
optional IRCM-DV+.

Controlling Two Display Devices
For another way to control two projectors, set up the Display On/Off buttons
to each control a different projector. The MLS port is typically used to control a
connected Extron switcher. However, you can disable the MediaLink switcher
support mode, then add a driver to that port. This same general procedure
can be used to make the MLC control any other device that uses RS-232 serial
communication for control.
The following illustration shows how the MLC is wired for this example and which
button is configured to control which projector and port.

prevent front panel changes or to restrict who can make front panel selections and
adjustments during certain hours and days. For full details, including instructions
on how to schedule front panel lockout periods, see “Front Panel Security Lockout
(Executive Mode)” starting on page 3-7. Setup instructions begin on page 3-10.
Sending E-mail by Pressing a Button
For some installations, you may want to set up an MLC button to send an e-mail
requesting projector repairs or requesting assistance from the front office or the
facility’s security or maintenance departments. Follow these steps to set up a
monitor to track a button press and send an e-mail as the action.

Working With a Non-MediaLink Extron Switcher
Although the MediaLink Controller’s MLS port can be used as an auxiliary RS-232
port for controlling another type of device, it is usually used to connect an Extron
MediaLink Switcher (MLS) or PoleVault Switcher (PVS). The MLC recognizes and
communicates with MLS and PVS switchers without requiring additional drivers or
configuration, unless you want to remap switcher inputs to the MLC’s buttons.
You can control an Extron switcher such as an MPS 112 or MPS 112 CS via the MLS
port if all of the following conditions are met:
• The MPS switcher uses firmware version 1.12 or higher.
• The MPS is in single switcher mode. It must be in single switcher mode (not
separate switcher mode) to be controlled by the MLC.
• The MLC uses firmware version 1.07 or higher. This is required in order to
bidirectionally track inputs greater than 6.
Also, if the input buttons are in input mode, the MLC and MPS buttons track
bidirectionally: an input button press on one device is indicated on the other device.
To set up the MLC to control an MPS 112 Series switcher, cable the MLC and
connect the MPS switcher to the MLC’s MLS port, then follow these steps:
1.
Create a new Global Configurator project that includes an MLC.
2.
In the IP Link tree view window, click on the MLC to be configured.
MLC 226 IP Series • Special Applications
6-17
PRELIMINARY
The MLC can recognize Extron switchers other than MLS and PVS models,
but as a single, generic type of switcher. For example, the MLC considers an
MPS 112 switcher to be the same as an IN1508 or an SW 4AV. The MLC supports
bidirectional communication for input switching and volume control, just as it does
for the MLS and PVS switchers.

Glossary
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.
ARP (Address Resolution Protocol) is a protocol which assigns an IP address to a
device based on the device’s MAC or physical machine address.
DHCP (Dynamic Host Configuration Protocol) is 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 software package that controls the interface between the controller and
peripheral 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 controls an MLC 226 IP. Event scripts are written in
the “Extron C” language (.sc), and compiled into an event script (.evt). The
Global Configurator program performs this compilation and uploads the
compiled event file 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, they
run continuously on the unit.
HTTP (HyperText Transfer Protocol) is 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.
MAC (Media Access Control) 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.

PRELIMINARY
Custom Web page is any file that can be loaded into an MLC 226 IP and served
by the MLC’s internal Web server. The Web page provides a way to control
the MLC 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.
Reference Material, cont’d
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 is the portion of an IP address that is specifically identified by the
subnet mask as the subnetwork.
PRELIMINARY
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.
Switcher slaving is an old term sometimes used to indicate that a device such as
the MLC or a main switcher unit is being used to control one or more A/V
switchers.
Switching rotation is another term for the set of buttons that are controlled by
the firmware. This is a mutually exclusive set of buttons controlled by
firmware (not scripts) that causes an input switching SIS command (1!, 2!,
3!, and so forth) to be sent via the MLS port when each button is pressed. In
Global Configurator, setting a button for input button mode is the same as
designating that button as part of the switching rotation.
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.
Tool tip is text that appears when the mouse pointer hovers over a button or other
item on screen.
UDP (User Datagram Protocol) is an Internet protocol for sending short packets of
information quickly between networked devices. It is faster than TCP and
is often used for broadcast and multicast communication, but it does not
include data verification to ensure that all packets arrived at their destination.

MLC 226 IP Series • Reference Material
Verbose refers to a wordy way of speaking. For the MLC and other IP-enabled
products, verbose mode is a communication mode in which the device
responds with more information than it usually would—more than
the device, itself, needs to send. Verbose mode is usually enabled for
troubleshooting and disabled for daily use. Verbose mode creates more
network traffic than usual and can slow down performance.
File Types: a Key to Extron-specific 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.
___.cdc — These are compressed device configuration files created and used by
Global Configurator.
___.cdc files should NOT be deleted.
___.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 Global Configurator,
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
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.
C
Event files should NOT be deleted. They are necessary for the MLC’s
operation. Never delete the main event file (0.evt).
________.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.

PRELIMINARY
MLC 226 IP Series
Firmware Updates
If the need arises, you can replace the Extron MLC controller’s main firmware via
an IP connection without opening the unit or changing firmware chips.
Determining the Firmware Version
There are several ways to check which version of firmware the controller is using:
• the IP Link Settings tab within Extron Global Configurator software
• the System Status or the System Settings page of the controller’s embedded Web
pages
• the Info page of GlobalViewer® Web pages (if installed on the controller)
• the Version column within Extron IP Link® Device Manager software
• the response from the MLC to an SIS command of 1Q or 0Q (See chapter 5.)
PRELIMINARY
Using the Global Configurator software
1.
Via RS-232 or Ethernet, connect a PC (on which the Global Configurator
program has been installed) to the MLC.
2.
Start the Global Configurator (GC) program and open a project. (See the
MLC 226 IP Setup Guide and chapter 4 of this manual for details.)
3.
In the window on the left side of the GC screen, click on the name of the MLC
for which you want to check the firmware level.
4.
In the right side of the GC screen, click the IP Link Settings tab.
5.
Click the Refresh button. The firmware version is listed in the System
Description area.
Using a Web browser
The controller comes with a set of factory default embedded Web pages. Also, if
the MLC controller is used as part of a network of devices based on Extron IP Link®
technology, such as IP Link interfaces, the GlobalViewer application could be
installed in the MLC as well as in other IP Link devices within the network. Refer
to the Global Configurator help file for information on how to use that software and
the resulting Web pages.
1.
Connect the controller to a PC via an Ethernet connection, or connect the
controller and the PC to a network/LAN. See chapters 2 and 4 of this manual
and read the MLC 226 IP Setup Guide for details.
2.
Start a Web browser program (such as Microsoft® Intenet Explorer or
Netscape® Navigator®).
3.
Type the MLC’s IP address into the browser’s address area and log on to the
MLC’s internal Web page (see chapter 4) or to the optional GlobalViewer Web
page stored in the MLC. (See the Global Configurator help file for details.)
N If GlobalViewer is installed in the MLC, the GlobalViewer Web pages appear by
default.
• GlobalViewer Web pages are supported by Internet Explorer, but not by other
browsers. GlobalViewer features may not work properly when viewed via
Navigator, Firefox, or other browser programs.
• To reach the factory default Web pages on a controller that has been set
up for GlobalViewer, type http://<IP address>/nortxe_index.html into
the browser’s address area, substituting the unit’s actual IP address for
“<IP address>”. For example, http://10.13.196.42/nortxe_index.html.

Firmware Updates, cont’d
Updating the Main Firmware
Most firmware upgrade tools (except Extron Firmware Loader) require the PC and
the controller to both be connected to an Ethernet network. Firmware Loader offers
the option to use either an IP or an RS-232 connection for the firmware upgrade.
The instructions for each method of updating the MLC’s firmware assume you
have installed the appropriate software on your PC first.
N Because the MLC must be reset after a firmware update, the existing
configuration will be erased. You should save the existing configuration to
a file (see chapter 4) before replacing the firmware. If the file is saved, the
configuration can be restored to the MLC later using Global Configurator.
N Check the Extron Web site (www.extron.com) for firmware-related documents,
instructions, patch files, and new firmware files before loading new firmware into
the controller. We recommend that you read the firmware release notes (available
from www.extron.com) before beginning the firmware update.
PRELIMINARY
Locating and downloading the firmware
1.
Visit the Extron Web site (www.extron.com) to find the latest, appropriate
firmware file (MLC 226 IP) you want to update.
2.
Download the executable installer file (*.exe) from the Web site and run the
installer program. The program automatically stores the firmware file on
the PC in C:\Program Files\Extron\Firmware\MLC_226_IP\xx (a folder
specific to that version).
3.
Write down the firmware filename and location for later use. The filename
ends in .s19 such as MLC226IPvxxx.s19 where xxx is the version number
(x.xx) or MLC_226_IP_yy_yyyy_yy_Vx_xx.S19 where Vx_xx indicates the
version number (x.xx).
N The firmware update file must have a filename extension of .s19. If the file does
not have that extension, it will not work properly.
Updating firmware via the MLC’s embedded Web page
Firmware uploads may be performed via a Web browser and the MLC’s internal
Web page. This method allows you to update one MLC at a time via an IP
connection.
1.
Download the firmware file.
