Introduction

About This Manual

This manual provides detailed information and best practices recommendations
about cabling and configuring the Extron MLC 104 Plus Series MediaLink®
Controllers, and reference information about the controllers’ specifications,
dimensions, programming, and special applications.

It does not contain instructions on the most basic setup steps: those are covered in
the MLC 104 Plus Series Setup Guide, which describes how to set up the hardware,
how to use the Global Configurator (GC) program to download drivers, add A/V
devices to a GC configuration, configure the front panel buttons, set a shutdown
schedule, and set up e-mail alerts to flag a projector disconnection or warn that
lamp hours are exceeded.

About the MLC 104 Plus Series MediaLink® Controllers

The MLC 104 Plus 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 also referred to as the MLC 104, MLC,
or “controller.” All models offer RS-232 and IR-based projector (display) control;
digital inputs and outputs for controlling items such as a projector lift, motorized
projection screen, and lights; and RS-232 remote control of an Extron switcher.

MLC 104 Plus requires GC version 2.50 or higher.

The IP models work with GC version 2.2 or higher

PRELIMINARY

MLC 104 Plus Series features

All models can be configured and controlled via a host computer using RS-232
communication, and the MLC 104 IP Plus models can also be configured and
controlled 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.

All models offer front panel controls. The optional IR 402 remote control (which
requires an optional IR signal repeater) and optional SCP 104 Series hardwired
control pads can be used with the MLC, and they mirror the MLC’s front panel
controls. Additionally, the MLC 104 IP Plus DV+ includes an IRCM-DV+ control
module (for DVD and VCR control) installed in the faceplate.

Additional features for IP models

Via Ethernet/IP communication the MLC 104 IP Plus 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 104 IP Plus,
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 104 IP Plus 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 — Up to 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 104 IP Plus 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 104 Plus Series offers two methods of projector or display 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.

A typical application for an MLC 104 IP Plus MediaLink Controller

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:

How the MLC 104 Plus Series Controllers Work: MLC Components and Interactions

Unlike the Extron MLC 206 Series MediaLink Controllers, the MLC 104 Plus
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 104 Plus Series controller works. Below are example diagrams of how the
MLCs interact 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 digital inputs or outputs, 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 panel(s), and changes made at the MLC’s front panel
(FPC, front panel control).

Each button on the MLC and on any connected SCPs 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.

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, CM-5BB, CM-9BLB, or IRCM-DV+) in order to allow limited control of
source devices.

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 and read the Global
Configurator Help file to learn about configuration. See chapter 4 of this manual for

special SIS commands for the IRCM-DV+.

A few optional IRCM, RCM, and CM control modules

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 (but not for setup).
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.

Many features must be set up in order for the MLC to function. See chapter 3,

“Software‑based Configuration and Control”, and the MLC 104 Plus Series
Setup Guide for information about Global Configurator, which you must use to
set up most features of the MLC.

Buttons

The MLC 104 Plus Series controllers have backlit buttons. The functions, events,
and scripts associated with these buttons are available with all models. Pressing
the corresponding button on the Extron IR 402 remote control or an Extron SCP 104
keypad will cause that button’s functions to be executed exactly as if you had
pressed a front panel button.

By default all buttons illuminate brightly when selected (active), and light dimly
when deselected. The button caps are removable so the button labels can be changed.

Each Display On/Off, Function/Room, and Input button can be set up to perform a
sequence of 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 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

To avoid conflicts with the front panel lockout PIN feature, Extron recommends

configuring the Display Power buttons so that the MLC sends projector/display
commands upon the button release instead of on the button press.

Input selection buttons — These buttons, labeled 1 through 4, can

be configured to perform a variety of functions. Each button can
be configured for input selection and to execute the IR or RS-232
commands of your choice, or trigger event scripts and/or port
monitoring. By default they are a mutually exclusive group: only
one of these buttons can be selected at a time. Also, by default
each button is associated with an Extron input switching Simple
Instruction Set (SIS
bidirectional communication via the MLC’s MLS RS-232 port. See
the picture at right.

Alternatively, the buttons can be reconfigured (via software) to
select different inputs and to trigger different commands. See chapters 3 and
4 for details.

Press an input selection button to select the desired audio and video input
on the projector or an optional Extron switcher. The button for that selection
lights brighter and remains lit brighter until a different input is selected.

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.

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 four input buttons are selectable. Which buttons
are or aren’t configured for input switching can be set via Global Configurator.

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, send a digital output signal, or
send a serial command via the MLS RS‑232 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 a
switcher is slaved to (controlled by) the MLC.

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/

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 3 and the

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 chapter 4 on SIS programming for details) or encoder
scaling in Global Configurator (see the Global Configurator Help file). If you
need further assistance, contact Extron and ask to speak with an applications
engineer.

If the MLC is configured for use with a MediaLink Switcher or for some
projectors, the MLC’s LEDs indicate volume ranges (with steadily lit LEDs)
and minimum/maximum volume limits (with flashing LEDs), as shown in
the following diagram.

If the MLC is configured for increment/decrement volume
adjustment, the LEDs scroll up/down briefly. See the example below.

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 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. Button and knob functions on the IR 402
remote control, SCPs, or control modules are also locked. Changes can still be
made via RS-232 or, for IP models, via Ethernet (Telnet or Web browser) control.

The SIS command 3X corresponds to and also enables this mode (

Preparing the MLC for front panel lockout

To allow access to front panel changes to specific personnel while the front panel is
locked, you can set a user and/or administrator PIN and set which type of PIN, if
any, is allowed to unlock the panel.

Setting up and enabling or disabling PINs

Using the Advanced Configuration tab within Extron Global Configurator (GC)
software, you can configure which PIN to enable (which PIN will be allowed to
unlock the front panel), or disable both PINs so that no one can access the front panel
during front panel lockout. And you can set the four­digit PINs for the administrator and for users.

Each digit of the PIN must be a number

from 1 to 4 because they represent the MLC’s
four input buttons, which will be used as a
numeric keypad. By default, both PINs are set
to 1423. Refer to the Global Configurator

Help file for the PIN setup procedure.

You can set the MLC’s front panel to be automatical­ly locked at certain times and days by setting up a schedule using the Schedule tab
within the Global Configurator software and uploading it to the MLC. The Global
Configurator Help file includes instructions on how to set up a scheduled action.

The IR learning receiver sensor on the MLC 104 Plus Series’ top panel can receive
and “learn” commands from other devices’ infrared
remotes so you can create an IR driver
file to control the projector or input
devices such as a VCR or DVD player.
IR learning of projector control codes
is only necessary if there are no RS-232
codes available for that projector or if
you need to customize the driver.
Refer to the IR Learner help file for IR
learning procedures.

This receiver accepts infrared signals
of from

30 kHz to 62 kHz. The IR
remote control must be pointed directly
at the receiver for best results. The diagram

This configuration port requires 38400 baud communication. This is a higher

speed than many other Extron products use. Global Configurator software
may automatically set 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.

For the IP models, Extron recommends configuring and controlling the MLC via

the LAN connector on the right side panel. Ethernet connections are faster and
more reliable.

Wiring for IR display control

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

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.

Maximum distances between the MLC and 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.

Wiring for IR control of up to two sources

Alternatively, an MLC can use infrared signals and IR Emitters to control
several source devices. However, the MLC’s direct insertion captive screw
connectors have small openings that accept just one wire per pole. To connect
up to two IR Emitters to the MLC, insert one ground and one signal wire
in the MLC’s Display RS-232/IR port, then connect the IR Emitters to those
wires. If using all single emitters or all double emitters, wire the emitters in
parallel. If using a mix of both single and dual emitters, see the

IR Emitter

Installation Guide, part number 68-808-01.

Series controller or other items, 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 104 control panels to this
port. A maximum of seven devices can be connected to this port. See the
figures on pages 2-13 and 2-14.

N

N

The SCP 104 must have firmware 1.01 or greater and DIP switch 4 in the

On (up) position to operate with an MLC 104 Plus Series controller. Refer to
the SCP 104 User’s Manual for more details.

The SCP 104 replicates the MLC’s front panel controls. The SCP 104 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
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.

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. Wire the connections as shown
in the diagrams on the following pages.

PRELIMINARY

Extron Comm-Link (CTL and CTLP) cable is
recommended for these connections. Before inserting
wires in the connectors, strip the cable and apply heat
shrink as shown at right.

T

For best results and to avoid short circuits, Extron

recommends using shielded wires or wires insulated
using heat shrink (instead of bare wires) for the
common/drain wires.

N

N

N

The maximum distance between the MLC and a

connected device is 200’ (61 m).

The CommLink port provides up to 12 VDC for powering the SCP control panel

or other devices. The automatic current protection circuit for this port limits the
draw to 0.5 amperes.

SCP control panel or control modules (CM, IRCM, RCM) used with the MLC are

affected by front panel security lockout (executive mode) status changes.

Digital I/O ports — The Digital I/O area (shown at right) provides

c

three ports that can be configured as digital inputs or outputs,
with or without +5 VDC pull-up. Connecting these ports to
sensors, switches, LEDs, or relays allows for a way to trigger
events or functions (such as triggering relays, issuing commands,
or sending an e-mail) that have been configured using Global
Configurator (GC) software.

C

Configure these ports using Global Configurator software or SIS commands

first, and then connect wires the MLC’s ports. A mismatch between port
configuration and wiring can cause malfunctions or unit failure.

Digital input — To allow the MLC to monitor devices such as push buttons,
connect a switch, motion sensor, moisture sensor, tally feedback output, or a
similar item to a digital input port. When one of these ports is configured as
a digital input, it is set to measure two states: high and low. The port accepts
0 to 12 VDC input. 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, pull-up resistor for
this circuit.
