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:

• AnIRoranRS-232driverle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.

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.

PRELIMINARY

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.

Setup operations cannot be performed from the remote control. Pressing the remote’s Display Mute On and Display Mute Off

buttons sends the 1M and 0M SIS commands (respectively) to the MLC. See page 4‑8 to learn about these commands.

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 (via IR Emitter) 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 Features and Operation

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

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.

If the MLC is used without an optional switcher and the MLC has been set up

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.

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 software’s help ﬁle for details.

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.

Conﬁguration port

Conﬁg (host control) 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 to 2.5 mm stereo mini TRS RS-232 cable (part #70-335-01) or make your own cable. See page 2

This port requires 38400 baud communication, a higher speed than many

other Extron products use. The conﬁguration software automatically sets the connection for the appropriate speed. If using HyperTerminal or a similar application, make sure the PC connected to these ports is set for 38400 baud.

Extron recommends conﬁguring and controlling the MLC via the LAN

connector. Ethernet connections are faster and more reliable.

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 ( For details, see chapters 3 and 4. 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, using the MLC’s input buttons as a numeric keypad for PIN entry, as shown

page 2-7.

Enabling and disabling front panel lockout via the embedded Web pages and the front panel

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.

Using the Web pages (IP models)

1. Using a Web browser, enter the MLC’s IP address to open the MLC’s embedded Web page. If an administrator password has been set and if you are prompted to do so, type in the administrator password.

2. Click on the Configuration tab, which opens to the System Settings page.

3. Select either Off or Disable Front Panel, SCP, Control Modules and IR in the

Executive Mode settings area. See the following picture.

see page 4 -10).

PRELIMINARY

If Disable Front Panel, SCP, Control Modules and IR is selected via the

System Settings factory default Web page, front panel lockout can’t be enabled/ disabled via the front panel unless PIN Mode is enabled. See page 4‑40 to ﬁnd the SIS commands for PIN enabling/disabling.

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 at right indicates the best distances and angles at which to hold the remote control.

IR remote control

The MLC 104 Plus Series controllers do not have a built-in IR receiver that accepts signals for controlling the MLC, itself. However, you can connect an Extron IR Link or an IR Sensor remote IR receiver to the MLC’s CommLink port as shown in “Additional control connections,” starting on page 2-12. Those devices can receive signals from an Extron IR 402 infrared remote control, which mirrors the MLC’s front

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.

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

CM/IR/SCP (CommLink) port — For remote control of the MLC 104 Plus

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.

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.

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.

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

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.

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.

When a digital I/O pin is configured as a digital output, it is set to offer two output states: “on” and “off”.

When the port is set to an “on” state, switch 1 (SW 1) closes and the I/O pin connects to ground.

When the port is set to the “off” state, switch 1 opens and the I/O pin floats.

The MLC 104 Plus Series controller cannot provide TTL level outputs like some of the IP Link interfaces. Switch 2 cannot be enabled when I/O pin is used as an output.

When used as a digital output, a digital output pin on the MLC may not work with certain devices requiring contact closure control. Although the illustration shows a short to ground when switch 1 is enabled, the actual circuit does not provide a completely grounded output. For any devices requiring contact closure control, it is recommended that relays be used.

MLS connector — To control an optional Extron switcher or other RS-232

controllable device, connect a cable between this 3.5 mm direct insertion captive screw connector and the RS-232 port of the other device. By default this port supports any Extron switcher without additional drivers. If it is used to control other products, additional device drivers may be required.

If you connect an optional switcher (such as an Extron MLS Series or PVS Series switcher) to the MLC, you must connect a ground wire between the switcher and the MLC, as shown in the following diagrams.

The commands issued from this port are standard Extron SIS commands, and

they follow the typical Extron RS‑232 protocol:

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.

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.)

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 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.

The Reset LED flashes 4 times in quick succession during reset.

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.

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.

3 Hold down the Reset button

for about 3 sec. until the Reset LED blinks once, then release and press Reset momentarily (<1 sec.) within 1 second.

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 release and press Reset momentarily (for <1 sec.) within 1 second.

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 release and press Reset momentarily (for <1 sec.) within 1 second.

Use mode 1 to revert to the factory default firmware version if incompatibility issues arise with user-loaded firmware.

Mode 3 is useful for troubleshooting.

Mode 4 enables you to set IP address information using ARP and the MAC address.

Mode 5 is useful if you want to start over with configuration and uploading, and also to replace events.

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.

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.

The reset modes listed below close all open IP and Telnet connections and close

all sockets. The following modes are separate functions, not a continuation from Mode 1 to Mode 5. Also, IP settings do not apply to the MLC 104 Plus.

Communicating with the MLC

To communicate with the MLC, you must power on the MLC and the PC you’ll use to conﬁgure it, and connect the two devices for IP (network, for IP models) or serial (RS-232) communication.

• Power: see chapter 2 for wiring instructions. It’s best to power the unit using the 12 VDC external power supply that is shipped with the MLC.

• Communication: to connect the MLC to a network (IP models) or to connect it directly to the PC using a serial cable (all models), of this manual for wiring instructions. See “Conﬁguring IP-enabled MLCs for Network Communication,“ below to set the unit up to talk with the PC.

Conﬁguring IP-enabled MLCs for Network Communication

To function together, both the PC and the MLC 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 104 IP Plus must be set up so it can be connected to a LAN or other network.

see page 2-9 or page 2-19

When you power on the MLC for the ﬁrst time, you have a choice of several ways to set up the controller’s IP address:

• UsetheGlobalConguratorsoftwareviatheLANconnector.

• UseSIScommandsviaanRS-232connection.

• UseSIScommandsviaTelnetandtheLANconnector.

If you use a Web browser or Telnet the ﬁrst time you connect a PC to an IP model controller via IP, you will probably need to temporarily change the PC’s IP settings in order to communicate with the controller. See “Setting up the PC for

IP communication with an IP-enabled 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. After you have set up the MLC for network communication, you can reset the PC to its original network conﬁguration via RS-232 or IP connection.

MLC 104 Plus Series’s RS-232 protocol:

• 38400 baud

• 8databits

• 1stopbit

• Noparity

• Noowcontrol

Network and IP features apply only to the MLC 104 IP Plus products, which are

the IP‑enabled models. The MLC 104 Plus does not support IP Link® features.

PRELIMINARY

MLC 104 IP Plus’s LAN port defaults (IP models):

• 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

The conﬁguration port requires 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 this port is set for 38400 baud.

Software-based Conﬁguration and Control, cont’d

Once an IP-enabled controller has been conﬁgured, an Ethernet (intranet or Internet) connection can be used to contact, conﬁgure, or control it.

The following instructions assume that you have already connected the Windows-based PC to the MLC 104 IP Plus’s LAN port or to the Conﬁg port, and powered on the controller and the PC.

Both your computer and the MLC must be connected to the same subnet on a LAN

(using a straight‑through cable). Alternatively, you can use a crossover Ethernet cable to connect the controller directly to your computer’s Ethernet card.

Conﬁguring the MLC 104 IP Plus 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 104 Plus 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’s IP address.

Conﬁguring the MLC 104 IP Plus for network communication using the ARP command

You can use the ARP 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.

Use ARP to conﬁgure the MLC’s IP address as follows:

PRELIMINARY

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”.

4. At the PC, access the MS-DOS command prompt, then enter the arp –s

arp –s 10.13.197.9 00-05-A6-00-9A-BB

After the arp -s command is issued, the controller changes to the new address

The MLC must be conﬁgured with the factory default IP address

and starts responding to the ping requests, as described in the next step.

3-4

MLC 104 Plus Series • Software-based Conguration and Control

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.

You can reconnect using either Telnet or a Web browser to verify that the

update was successful.

6. After verifying that the IP address change was successful, enter and issue the arp –d command at the DOS prompt. For example:

arp –d 10.13.197.9 removes 10.13.197.9 from the ARP table or arp –d* removes all static IP addresses from the ARP table.

Conﬁguring the MLC 104 IP Plus for network communication via a Web browser

The default Web pages that are preloaded on the MLC 104 IP Plus are compatible with popular Web browsers such as Netscape Navigator (version 6.0 or higher), Microsoft 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).

Setting up the PC for IP communication with an IP-enabled 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 104 IP Plus 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 (all models) or IP connection (IP models). 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, MLC 104 IP Plus, or other Extron device) on a network. Once an MLC 104 IP Plus 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 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).

PRELIMINARY

Refer to the MLC 104 Plus Series Setup Guide for speciﬁc information on how to download the software. Refer to that guide and to the Global Conﬁgurator Help ﬁle for details and step-by-step procedures on how to start a GC project and perform basic setup tasks for an MLC 104 IP Plus. Both the setup guide and the help ﬁle contain instructions on how to set the MLC’s IP address, gateway IP address,

subnet mask, mail server IP address, domain name, Telnet port, Web port, SMTP username, and SMTP password so that the MLC is able to communicate with the

network. Obtain these parameters from your network administrator and set them before continuing.

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 IR Learner™, a free software utility for capturing infrared codes from a handheld IR remote control to create custom drivers for operating IR‑controlled devices like the MLC that use IP Link and GlobalViewer.

The Global Conﬁgurator Help ﬁle explains these features in the reference section about the Advanced Configuration tab and in the MLC-speciﬁc instructions for conﬁguring advanced settings. You may want to keep the following items in mind while conﬁguring advanced settings. And not all features of this tab are listed below.

Power Settings (Display power up/power down settings)

When the display is on, delay I/O switching for: — This feature prevents a

second input switch for the speciﬁed duration (0 to 5.0 seconds in 0.5 second increments). This allows a projector to synchronize with the new input signal before switching inputs again.

The I/O switching delay period can be set here or by using special SIS command

54# on

When powering up/down delay for: — Most projectors require a certain amount

of time for lamp warm-up and cool-down during which they cannot display an image. These delays can also be set using special SIS commands (1# and 2#, see

page 4-33 in the SIS programming chapter).

Repeat IR power down — Some IR-controled projectors/displays must receive a

second power down command. If selected, this feature automatically sends the

page 4-40.

Global Conﬁgurator automatically sets the warm‑up and cool‑down delay times

based on default values in the display/projector’s driver. SIS commands override the default settings. For best results, set delay times to 2 to 4 seconds longer than the times required by the display/projector. This ensures that the correct Display power button state is shown on the front panel and on the GV and standard embedded Web pages.

power off/power down command twice. 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 — This setting ensures that the

inputs of the MLC and of the display device are coordinated when the display is powered on.

Lockout I/O switching while display powers On or Off — This feature prevents

input switching during the display power up and power down periods. This I/O switching lockout is the same as SIS special command 53# ( this command to work you must also set the power up and power down delay periods (mentioned above).

Hold power-down button for two seconds — This prevents shutting down the

display or projector by accidentally pressing the Display Off button. When this feature is enabled, you must press and hold the front panel Display Off button for two seconds before the power-off sequences can start. The corresponding SIS command is 22#.

Volume settings

When adjusting the volume use — For a projector, display, or audio output

device, volume is controlled by 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. Refer to the user’s manual for the display or audio device to choose the best method for volume adjustment.

Volume encoder scaling factor (0-255) — This feature allows you to slow

Encoder scaling gives the programmer the ability to slow the knob down to

Although this feature is mainly for range type volume control, it applies to any

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 4‑33 and 4‑39.

down the volume knob (the encoder) on the MLC’s front panel. This feature addresses a scenario 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 is able to detect and process. When the projector does not detect some of the volume change commands, a choppy volume ramp occurs.

a speed the projector can handle. The drawback is that users must turns 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.

Printing a wiring block diagram

Once you have conﬁgured a system using Global Conﬁgurator, you can generate and print a simple block diagram of what products to wire to which of the MLC’s ports. The diagram includes model names, DIP switch settings for control modules, and the type of communication (IR or RS-232) conﬁgured for each port. Read the Global Conﬁgurator Help ﬁle’s “Reference Information” section about the File menu for details.

This procedure requires Microsoft Word software. The installer or user must

provide that software. It is not an Extron product.

GC processes the information about the selected device(s), generates a document containing the wiring diagram, and opens that document in Word. Print the diagram(s), save the ﬁle, if desired, and exit Word. Close the Global Conﬁgurator Print Wiring Diagrams window.

Updating ﬁrmware

If the need arises, you can replace the MLC’s ﬁrmware without opening the unit or changing ﬁrmware chips. See appendix B, “Firmware Updates”, for instructions on how to update the controller’s ﬁrmware.

Save the existing conﬁguration project before replacing the ﬁrmware.

Saving and uploading the conﬁguration

This is not an advanced conﬁguration function, but when you ﬁnish creating the conﬁguration in Global Conﬁgurator, you must save the GC project and upload the conﬁguration to one or more MLC units. See chapter 3 of the MLC 104 Plus Series Setup Guide (shipped with the MLC) for instructions.

Controlling an IP Link-enabled MLC

You can control the MLC 104 IP Plus and devices connected to it by using the MLC’s factory-embedded Web pages or its GlobalViewer (GV) Web pages that were created when you uploaded the GC conﬁguration or a customized graphical user interface (GUI).

Embedded Web pages

The MLC 104 IP Plus features an embedded Web server, which includes factoryset Web pages. These pages can be replaced with user-designed ﬁles, but the default Web pages provide many basic features for monitoring, conﬁguring, and controlling the MLC via a Web browser. These Web pages provide some of the features of the conﬁguration program. This section provides an overview of the embedded Web pages.

To access the embedded Web pages,

1. Launch a Web browser (Internet Explorer, Netscape Navigator, Mozilla Firefox) on the connected PC, and enter the MLC’s IP address in the address ﬁeld.

2. In the Connect to <IP address> dialog box, shown at right, enter the MLC’s IP address or text of your choice in the User Name ﬁeld, type in the administrator password in the Password ﬁeld, and click OK. The MLC 104 IP Plus’s default Web page appears.

If the MLC has not already been

conﬁgured with a password, this password dialog box does not appear; the default Web page opens directly.

Passwords must contain 4 to 12 alphanumeric characters. Symbols and spaces

are not allowed, and the passwords are case sensitive.

Administrators have access to all of the Web pages and are able to make

changes to settings. Users can access the System Status and Control: User Mode pages only.

GlobalViewer® Web Pages

The MLC 104 IP Plus 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 browser-based 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 104 IP Plus 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 for speciﬁc information on how to use the software and perform basic setup tasks for a MLC 104 IP Plus.

Four screens for the MLC are available via Global Viewer: Control, Monitor, Schedule, and Info ( Global Conﬁgurator Help ﬁle for details on each screen and how to use the GlobalViewer pages.

To work with Global Viewer Web pages, you must use Microsoft Internet

Customizing the MLC’s Control Web Pages

Extron offers Web page templates that can be customized using standard HTML editing tools to provide a different interface to the user 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 MLC IP models:

• yourGlobalViewerprojectlecontainingsystemcongurationdetails

• yourchoiceofavailablecolorschemes

• yourchoiceoflabelsforpanelbuttons

SIS™ Programming and Control

The MLC 104 Plus 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.

MLC 104 Plus Series units must be conﬁgured before use. As shipped the

The

controller can trigger basic input switching on an optional MLS switcher, but it cannot control any other devices before being conﬁgured.

The MLC 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 for IP models, version 2.5 or higher for MLC 104 Plus), and both of those methods can be accessed via RS-232 (all models) or Ethernet LAN connection (IP models). See chapter 2 for pin assignments and other details on the conﬁguration and control ports. For information on the software and the MLC 104 IP Plus’s embedded Web pages, see chapter three.

The conﬁguration port requires 38400 baud communication. This is a

higher speed than many other Extron products use. The Global Conﬁgurator (version 2.2 or higher for IP models, version 2.5 or higher for MLC 104 Plus) 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.

MLC’s IP address: 192.168.254.254

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 via RS-232 or via a verbose (see page 4-21) 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).

• IfanMLC IP model 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 (IP models)

The “]Password:” prompt requires a password (administrator level or user level) followed by a carriage return. The prompt is repeated if the correct password is not entered.

or “ for both administrator and user, the unit will default to administrator privileges.

Error responses

When the MLC 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 colon and 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:

= Commands that give an E14 (not valid for this conﬁguration) response if the

unit’s current conﬁguration doesn’t support that command.

= Commands that yield an E22 (busy) response.

= Commands that give an E24 (privilege violation) response if you are not logged

in at the administrator level.

= Commands that may yield an E27 (invalid event number) response.

= Commands that may give an E28 (ﬁle not found) response.

Using the command/response tables

The MLC can be controlled via either a Telnet (port 23, IP models only) or RS-232 connection using ASCII commands. IP models can also 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 4-8 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.

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

the factory; it is the version the controller

Button associations (virtual mapping) for an IRCM-DV+

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 even-numbered 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.

To use an optional IRCM-DV+ with an MLC, you need to associate the DVD portion of this module with an MLC input selection button, 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 IRCM-DV+’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+.

For MLC 104 IP Plus Series MediaLink Controllers, you can assign both the DVD and VCR portions of an

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 ( 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. Button press/release emulation commands start on page 4-37.

The input button register numbering shown in the following illustrations is for a stand‑alone MLC. It does not

include button numbering for an optional auxiliary switcher connected to the MLS port.
