and Interactions

PRELIMINARY

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 confi gured 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 Confi gurator™ program. The software offers many more setup
options than does SIS programming.

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:

PRELIMINARY

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 fl ash

memory for storing Extron and user-supplied Web pages, confi guration
settings, and device drivers. Data in fl ash 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 Confi gurator 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 notifi cation — 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 fi les to perform all functions except basic input switching
and volume control. The event fi les defi ne, 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 confi gured completely via the Extron Global Confi gurator
software. Once you have set up how you want it to work (assigned drivers to
ports, confi gured buttons and relays, and set up IP addresses and functions), that
information is saved to a project fi le that is uploaded into the MLC.

The confi guration information is used to create the “main event” (0.evt) script fi le
that defi nes the MLC’s operation. The main event fi le 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 fi le to monitor any button press or release and to generate
the actions (issuing commands, triggering relays, switching inputs) associated with
the buttons.

Both confi guration ports require 38400 baud communication. This is a higher

Digital input/output: pin 1 and the ground pin together act as a digital input/
output port (depending on confi guration). 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 confi gured using GC.

Digital input: when this port is confi gured 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.

Digital output — When this port is confi gured 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 fl oating.

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

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 confi gured that way via Global Confi gurator.
This allows for an additional way to trigger events or functions (such as
triggering relays, issuing commands, or sending an e-mail). When confi gured
as a digital input, this port is in one of two states: 1 (on, high) or 2 (off, low).

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.

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements pertain to the safe
installation of the MLC in a rack.

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) specifi ed by Extron.

2. Reduced air fl ow — Install the equipment in a rack so that the amount of air

fl ow 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 rack-

mounted 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 fi rst.

4. Mount the controller to the Euro Channel by attaching the faceplate to the two
backing plates using four #4-40 mounting screws. See the illustration below.

N

Make sure that the Euro Channel is grounded to an earth ground before

completing the installation.
