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.

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.

unused for long periods.

Electrical Code (NEC), the MLC must be installed in a UL approved junction box. The end user or installer must furnish the junction box; it is not included with the MLC.

PRELIMINARY

1. Remove the button from the MLC or SCP; use a small,

ﬂ at bladed screwdriver such as an Extron Tweeker to gently pry a button out from the front panel.

2. Locate the notch in the corner of one

side of the clear button cap.

3. Separate the white backing

(diffuser) from the clear button cap (lens); insert the blade of the small screwdriver into the corner notch and gently twist the blade.

4. Save the translucent,

white diffuser, but remove the text/ label insert from the transparent button cap.

5. Select one of the button labels from the

printed label sheets included with the device (MLC or SCP). Remove the label from its backing, if applicable.

6. Insert the button label into the button cap. Check for correct label orientation.

7. Align the white diffuser plate with the cap. The bumps on the diffuser plate

should be aligned (top and bottom) with the notches on the clear button cap. Firmly snap it into place.

8. Align the tabs on the MLC’s plunger with the notches on the diffuser plate.

Gently but ﬁ rmly press the reassembled button into place in the MLC’s or SCP’s front panel.

The front panel 2.5 mm mini stereo connector Conﬁ g port serves the same RS-232 function as this rear panel port but is independent from it.

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.

If the application calls for TTL compatibility, the circuit can be set up to provide a 2k ohm pull-up resistor to +5 VDC.

Front panel Conﬁ g (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.

The Power Sensor can be used to let the controller know when the projector/display is on or off. If these pins are not connected to a Power Sensor, the Pwr Sns and Ground pins can be used for 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.

Maximum distances from the MLC to the device being controlled may vary

Bottom Panel

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). Threshold voltages are <2.0 VDC = low, >2.8 VDC = high.

Additional control connections

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.

If outside factors such as ﬂ uorescent 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.

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.

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 ﬂ ash memory programming, port reassignment, or a controller reboot.

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.

Reset Mode Comparison/Summary

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

The MLC reverts to the factory default firmware. Event scripting will not start if

the MLC is powered o 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 s stopping.

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.

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

completing the installation.

Projector Control

Front Panel Features and Operation

The MLC can control a projector or other display device by using IR or RS-232 control. The MLC must be conﬁ gured for projector control in one of the following ways before it will send commands to the projector:

• An IR or an RS-232 driver ﬁ 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 Conﬁ gurator. The driver is saved to a folder within C:\Program Files\Extron\Driver2, and it is uploaded to the MLC via Global Conﬁ gurator.

• RS-232 command strings can be entered directly from a host computer using Extron Global Conﬁ gurator 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 ﬁ eld.

See chapter 4 and the Global Conﬁ gurator help ﬁ le or the IR Learner help ﬁ le for details on setting up the MLC and for downloading, programming, or learning projector control commands.

Many features must be set up in order for the MLC to function. See chapter 4,

“Software-based Conﬁ guration and Control”, and the MLC 226 IP Series Setup Guide for information about Global Conﬁ gurator, 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

ﬂ ashing

• a digital input/output operation—turn the digital output on or off, toggle it, or

pulse it

• a user-deﬁ ned RS-232 operation—issue a non-driver-associated RS-232

command (one that you programmed separately) via a speciﬁ c port (IR/Serial Out A, B, C; or the projector control port) or an internal command for the MLC, itself

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.

Display On/Off buttons — After they have been conﬁ gured, 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 Conﬁ gurator (GC) software, other functions and relays can be associated with each of these buttons.

Function/room control buttons and c 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 conﬁ gured 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 conﬁ gured, see the installation instructions in chapter 2 and the conﬁ guration software information in chapter 4.

Function/room control buttons — These have the same

capabilities as the input selection buttons ( typically used for triggering commands and functions other

By default these three buttons are each associated with a latching relay, as shown at right. However, any software-based conﬁ guration, regardless of whether the function buttons are conﬁ gured or not, overrides the default associations between these buttons and the relays.

If an optional Extron switcher is connected to the MLC, all six input buttons are selectable. Which buttons are and aren’t conﬁ gured for input switching can be set via Global Conﬁ gurator.

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 a switcher is slaved to the MLC.

Volume control

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 Conﬁ gurator 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 ﬁ le for details.

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 Conﬁ gurator (see page 4-14). If you need further assistance, contact Extron and ask to speak with an applications engineer.

IR signal sensors

These sensors allow for IR remote control of the MLC and for IR learning. The IR remote control must be pointed directly at these devices for best results.

IR control receiver — This larger infrared receiver accepts IR signals from the

Extron IR 402 infrared remote control, which mimics the MLC’s front panel controls.

If outside interference

(such as ﬂ uorescent lighting) affects the MLC’s functioning, you may need to disable IR control. Front panel IR control can be disabled using the 65# special function SIS command. See page 5-40 for details.

IR learning receiver — This

smaller sensor receives and “learns” commands from other devices’ infrared remotes in order 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 ﬁ le for IR learning procedures. This receiver accepts infrared signals of from 30 kHz to 62 kHz.

Host Control port (the 9-pin D connector), and it is independent of that port. This port makes it possible to upload and conﬁ gure 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 2-4 for a wiring diagram and port protocol.

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 ﬁ le 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 slaved 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

this manual for special instructions for the IRCM-DV+.

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.

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.

Setup operations cannot be performed from the remote control.

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.

Pressing the remote’s Display Mute On and Display Mute Off buttons sends the

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 identiﬁ cation 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 ﬂ ashes 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.

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.

Conﬁ guring the MLC for Network Communication

To function together, both the PC and the MLC 226 IP must be conﬁ gured 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 ﬁ rst time, you have a choice of several ways to set up the controller’s IP address:

• Use the Global Conﬁ gurator software via an Ethernet connection.

• Use the ARP command with an Ethernet connection.

• Use a Web browser with an Ethernet connection.

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

If you use a Web browser or Telnet the ﬁ rst time you connect a PC to the controller via IP, you must temporarily conﬁ gure 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 conﬁ guration.

MLC 226 IP’s RS-232 protocol:

• 38400 baud

• 8 data bits

• 1 stop bit

• No parity

• No ﬂ ow control

PRELIMINARY

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 conﬁ gured, an Ethernet (intranet or Internet) connection can subsequently be used to contact, conﬁ gure, or control it.

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 Conﬁ g port, and powered on the controller and the PC.

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

higher speed than many other Extron products use. The Global Conﬁ gurator 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.

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.

PRELIMINARY

Software-based Conﬁ guration and Control, cont’d

Conﬁ guring the MLC for network communication via Global Conﬁ gurator software

You can conﬁ gure the controller’s IP address via an IP/Ethernet connection using the Extron Global Conﬁ gurator (GC) Windows-based software.

Read the Global Conﬁ gurator help ﬁ le for basic information on using Global Conﬁ gurator 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.

Conﬁ guring 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 reconﬁ gured.

Use ARP to conﬁ gure 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 conﬁ gured 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

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.

Conﬁ guring the MLC for network communication via a Web browser

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).

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 conﬁ gured.

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 Conﬁ gurator, 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 conﬁ rm whether you need to set up the MLC 226 IP for DHCP (Dynamic Host Conﬁ guration Protocol) to have an address assigned automatically when you sign on.

Global Conﬁ gurator Software for Windows®

The included Extron Global Conﬁ gurator (GC) program for Windows offers the most complete way to conﬁ gure 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 conﬁ gured, its GlobalViewer Web pages allow the user to manage, monitor, and control the MLC and the devices connected to it.

Global Conﬁ gurator offers the best and easiest way to conﬁ gure the controller.

Using Global Conﬁ gurator: helpful tips

Resources and notes

• Some items in Global Conﬁ gurator correspond directly to the front panel controls. See chapter 3, “Operations,” for features and settings.

• The Global Conﬁ gurator help ﬁ le provides information on settings and on how to use the Global Conﬁ gurator program, itself.

• Basic setup steps are covered in the MLC 226 IP Series Setup Guide, which is shipped with the MLC. It includes instructions and examples on how to use the basic tabs in GC.

• If you will conﬁ gure the MLC at the installation site, Extron recommends using the driver subscription function to download drivers for all manufacturer and device types before you go out into the ﬁ eld.

• The Global Conﬁ gurator project ﬁ le contains conﬁ guration settings, and it can be saved to a directory or folder for backup or for installation on another MLC 226 Series controller. Saving a conﬁ guration is recommended before you perform a ﬁ rmware upgrade.

MLC 226 IP Series • Software-based Conﬁ guration and Control

• The MLC can be set up to allow conﬁ guration access to administrators only, and to prevent other users from making changes to the controller’s settings, events, and drivers. If an administrator password is set for the controller, nonadministrator end users can select inputs and adjust output volume but are prevented from making any other changes using GlobalViewer Web pages.

• IP addresses, subnet mask, and e-mail addresses follow standard naming and numbering protocol. The network administrator provides the IP addresses and subnet mask to be used with this controller.

• The unit name is any name (e.g., Room107MLC226IP, Lab1234mlc226IP, ConfRoomSystem, LectureHall8-cntrlr, etc.) that you want to use to label a speciﬁ c MLC controller unit. The default is a combination of the product name and part of the hardware address. This can be changed to your choice of alphanumeric characters and hyphens (-).

• Spaces are not permitted within a unit’s name.

• Underscores (_) are not permitted.

• Valid characters are A-Z, a-z, 0-9, and - (hyphen).

• The name cannot start with a number or a hyphen, and it cannot end with a hyphen.

• Maximum name length is 24 characters.

A brief guide to Global Conﬁ gurator’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 conﬁ gure. 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 conﬁ gured. See the illustration below for an example of the tabs that may be available when you conﬁ gure an MLC.

IP Link Settings shows all the IP-related settings, as well as the unit part number,

MAC address and ﬁ rmware 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 conﬁ gure 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

• port signal type (IR or serial)

• serial communication mode (RS-232 or RS-422)

• any device driver associated with that port

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).

I/O switching delay

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.

Software-based Conﬁ guration and Control, cont’d

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 conﬁ gured 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.

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.

PRELIMINARY

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 speciﬁ c range of values, or sending a simple command to increase or decrease the volume by a ﬁ xed 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 speciﬁ c level the audio output should not exceed when the projector/display is powered on.

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

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.

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 Conﬁ guration 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 ﬁ nd 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 I/O port settings

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 Conﬁ gurator 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.

PRELIMINARY

Miscellaneous settings

In this area of the Advanced Configuration tab you can choose whether to reset button statistics (which track how many times each front panel button is pressed) when uploading the latest conﬁ guration ﬁ le, and/or whether to upload the enhanced Web pages (which show photo-like versions of the MLC’s and control modules’ front panels) when the conﬁ guration is uploaded to the MLC.

An experienced Web developer can add images, modify text, and change background colors to create a look and feel that reﬂ ects your brand or your user’s speciﬁ c 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 ﬁ les ready to upload to the MLCs:

• your Global Viewer project ﬁ le containing system conﬁ guration 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 modiﬁ ed 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.

Host-to-MLC Communications

Commands and Responses

PRELIMINARY

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 Conﬁ g/RS-232 port or LAN port, or the front panel Conﬁ g port.

The MLC 226 IP must be conﬁ gured 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 conﬁ gured.

The MLC 226 IP can be set up and controlled by using Extron’s Simple Instruction Set (SIS) commands or the Extron Global Conﬁ gurator 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 conﬁ guration 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 ﬂ ow control

PRELIMINARY

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

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

speed than many other Extron products use. The Global Conﬁ gurator (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.

Host-to-MLC Communications

SIS commands consist of one or more characters per ﬁ eld. 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).

Chn The unit sends this response when an input is switched.

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 ﬁ rst powered on.

• If the MLC is on, it sends the boot and copyright messages when you ﬁ rst 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

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.

If the correct password is entered, the unit responds with “ 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 conﬁ guration 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 ﬁ lename or ﬁ le 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:

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

unit’s current conﬁ guration 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 (ﬁ le 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.

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.

ASCII to Hex Conversion Table

ASCII to Hex conversion table

•

PRELIMINARY

• Upper and lower case characters may be used interchangeably in the command ﬁ eld unless otherwise speciﬁ ed.

• 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.

• 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 preﬁ x 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]

For Web encoding only: data is directed to

the speciﬁ ed port and must be encoded (URL encoding) if it is non-alphanumeric. Change any non-alphanumeric character (%, +,

, etc.) within the data section into the corresponding hexadecimal equivalent, %xx, where xx represents the two-character hex byte. For example, a space (hex: 20) would be encoded as %20 (hex: 25 32 30) and a plus sign (hex: 2B) would be encoded as %2B or hex 25 32 42.

(-12.00 to +14.00) represents the time difference in hours and minutes (+/-hh:mm) relative to Greenwich, England. The leading zero is optional. For example, 5:30 = 05:30. Do not use a plus (+) sign if the GMT offset is positive.

volume level is limited by the max. volume range command (

Default volume = 25.

= Version (typically listed to two decimal

places, e.g., x.xx)

With Telnet you can use either an “Escape” (

In either method, {Data} = data that will be directed to a speciﬁ ed 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 ﬂ ash memory.

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 trafﬁ c 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 trafﬁ c on the network.

If tagged responses are enabled, all read commands return the constant string + data, the same as for setting a value.

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,

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.
