MediaLink VersaTools Switchers • Installation

Installation, cont’d

Aux/Mix Mono audio input (all models) —The Aux/Mix Mono audio channel is always active: its signal is output no matter which, if any, other audio input (input 1, 2, 3, or 4) is selected. For example, you could connect the output of a wireless microphone receiver to this port so the presenter’s comments can always be heard and are independent of the A/V source used for the presentation.

The mix output level can be adjusted between -43dB and +24dB.

The Aux/Mix level must be adjusted physically via the front panel control. It cannot be adjusted via

software.

Connect a 3.5 mm, 3-pole captive screw connector to one end of an audio cable as shown at right. Wire the other end to two tip-ring connectors or one tip-ring-sleeve connector as shown in 7 and 8, and connect it between the MLS 100 Series switcher and the auxiliary audio source.

Audio output (Out) (all models) — Connect self-powered speakers or another stereo audio device to the MLS via this 5-pole 3.5 mm captive screw connector. Depending on how the connector is wired, the audio output can be balanced or unbalanced stereo audio. Wire the connector as shown below.

OUT

CAUTION

Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

Later, after all the equipment has been cabled and powered on, use the MediaLink Control Program or an RS-232 controller to set the per-input gain/attenuation to match the correct audio output level for the kind of output (balanced or unbalanced) you need. See pages 2-9 and 4-10 for details on determining and setting the gain/attenuation to produce the desired output levels.

If you wire an audio output for balanced output, the MLS will output a unity signal (input level = output level). Wiring an audio output for unbalanced output causes the audio signal to be attenuated by 6dB. See pages 2-9 and 2-10 for instructions on adjusting audio gain.

Audio connections

The stereo audio inputs 1–3 (7 and 8 on page 2-5 and below) correspond to video inputs 1, 2, and 3. All four audio inputs can be selected via the front panel buttons, RS-232 control (including MLC), or the MediaLink Control Software. An audio signal from one of these inputs is output only when the corresponding input is selected. Using the MediaLink Control Software you can separately adjust the level of each of these audio inputs.

Via RS-232 control audio input signals can also be switched separately from the video signals (a feature called “audio breakaway”.) See pages 4-4 and 4-8.

Computer audio inputs (MLS 102 VGA only) — These inputs each accept unbalanced stereo audio input via a 3.5 mm stereo

mini receptacle (tipring-sleeve type). If you do not have a preterminated audio cable, wire the mini jack on each end of the cable as shown at left.

Audio Inputs (all models) — Each of these 3-pole 3.5 mm captive screw connectors accepts one unbalanced stereo or mono audio input. Wire each captive screw connector as shown at right, depending on the input type.

Connect two RCA-style (tip-ring) connectors to the other end of each audio input cable as shown here:

Control and power connections

MLC/RS-232 Power port (all models) — An Extron MediaLink Controller (MLC 206), a computer, or a third party RS-232 controller provides remote control of input switching and volume, and also provides a way to set the switcher’s audio input levels. To control and/or set up the MLS, connect a cable between this 5-pole 3.5 mm captive screw connector and an optional MLC 206, computer, or a third party RS-232 controller. Also connect an external 12VDC power supply here to provide power to the MLS and to the optional MLC.

Extron Comm-Link cable is recommended for this connection. If you use Comm-Link cable, the switcher and controller can be up to 250 feet (76.2 m) apart. Wire the captive screw connector for connection to either an MLC 206 or third party controller as shown in the picture on the next page.

• For a stand-alone MLS switcher, connect a cable from the host computer or a third party control system to this connector to set up and remotely control the switcher, connect a 12VDC power supply, and tie all the drain wires to the same ground.

• For an MLS switcher slaved to an MLC controller, connect a cable from the MLC’s MLS/Power port and from a 12VDC power supply, and tie all the drain wires to the same ground.

Once the system has been cabled and set up via the control software and the front panel Aux/Mix adjustment, the MLC or a host computer communicating through the MLC can be used to remotely control the switcher. Refer to chapter four of the MediaLink Controllers User’s Manual and to the MediaLink Control Program help file for details on configuring an MLC-MLS system.

An Extron IR Link infrared repeater cannot be used with the MLS 100 Series switchers. There is no connection for that device’s control signals.

The MLC to which the MLS 100 Series switcher is connected must have MLC firmware version 1.04 or

higher. The control/setup software must be version

2.0 or higher. Use one of the following methods to find

out the version levels of the MLC’s firmware and the control software.

• Connect the MLC’s RS-232 port to a computer or RS-232 controller, and send an SIS command (see chapter four) of Q to the MLC. The MLC will respond with its firmware version.

• Connect the MLC’s RS-232 port to a computer, start the MediaLink control software (see chapter four), and click on Help to display the software version, the MLC’s firmware version, and the MLS’s firmware version as shown in the example at right.

If your MLS’s firmware is an earlier version, contact Extron to obtain updated firmware.

Gain and attenuation are adjustable (from -18dB to +24dB) for each input (1 through 4) via RS-232 control only (using HyperTerminal, a third party controller, or the MediaLink Control Software). The gain and attenuation for the Aux/Mix input are adjustable only via the switcher’s front panel. (See page 3-3 for Aux/Mix details.)

Setup via the MediaLink Control Software

To avoid damage to your hearing, the output volume should be set as low as possible before you test the sound system.

1. Cable and power on all the equipment.

2. Start the MediaLink Control Software (see page 4-7), and

select the Switcher (MLS) Config portion of the program (the second tab from the left).

3. Select an audio input. See the picture below for an example.

4. Use the following table to determine the gain or attenuation. Match the desired level for balanced output or for unbalanced output, depending on how the output connector is wired.

Levels

Unbalanced

If you wire an audio output for balanced output, the MLS will output a unity signal (input level = output level). If you wire an audio output for unbalanced

output, it causes the audio signal to be attenuated by 6dB (gain = -6dB).

For dBV the reference is 1 volt. For dBu the reference is 0.775 volts.

5. In the control program, move the Audio Input Level slider to select the gain/attenuation for that input, as shown at left.

6. Repeat steps 3–5 for the other three inputs.

7. Test the system by listening to audio output for each input.

Start by setting the audio output set to the lowest level. 7a. If the audio output is too loud or is clipping

(becoming distorted as the loudest parts are cut off), decrease the gain for that input.

7b. If the output is too soft or inaudible, increase the gain.

Operation

audio does not change when you switch between the four selectable audio inputs.

The last selected input (including audio/video breakaway selections) will be the active input when the MLS is powered on.

Aux/Mix Level control — This potentiometer controls the auxiliary/mix audio volume. This channel’s audio is always output, no matter which, if any, other audio input (0, 1, 2, 3, 4) is selected. Use a small screwdriver to turn this control while you listen to the audio output. When the control is turned to its counterclockwise limit (-43dB), the Aux/Mix signal will be inaudible. You will hear the maximum Aux/Mix volume when the control is turned to the clockwise limit (+24dB).

Once this level is set, the Aux/Mix level remains the same no matter which input (1 through 4) is selected, and the Aux/Mix audio can be heard at that level even if the selectable audio inputs are muted or if audio input 0 is selected via RS-232 control.

The gain and attenuation for audio inputs 1 through 4 is adjustable only via RS-232 control (using a third party controller, a MediaLink Controller, or the MediaLink Control Software.) The gain and attenuation for the Aux/Mix input is adjustable only via the Aux/Mix Level control.

Executive mode — enabling and disabling front panel buttons

1. To disable front panel input selection (turn executive mode

on), simultaneously press input selection buttons 1 and 4 and hold them down for three seconds. All LEDs will light for about one second.

2. While executive mode is on, input selection can be

performed via RS-232 control or from an optional MediaLink Controller.

3. To enable front panel input selection (turn executive mode

off), repeat step 1 (pressing and holding buttons 1 and 4).

MLS 100 Series Front Panel (all models)

All the MLS 100 Series switchers share the same front panel design, shown above.

Input selection buttons and indicator LEDs — Press one of these buttons to select the desired audio and video input. The corresponding LED lights and remains lit while an audio-video input is selected. During audio breakaway (selectable only via RS-232 control, described in chapter four), audio is switched separately from video; the selected video input’s LED lights steadily, and the audio input’s LED blinks.

• The MLS 100 A accepts only audio inputs, so pressing one of these buttons selects an audio-only input.

• The MLS 103 V and MLS 103 SV offer three video inputs and four selectable audio inputs. Pressing button 1, 2, or 3 selects audio-video input 1, 2, or 3; pressing button 4 selects audio-only input 4.

• The MLS 102 VGA offers two computer-video inputs and four selectable audio inputs. Pressing button 1 or button 2 selects audio-video input 1 or 2; pressing button 3 or button 4 selects an audio-only input (3 or 4) .

If you select an audio-only input (input 3 or 4 for MLS 102 VGA, input 4 for MLS 103 SV and MLS 103 V) via front panel buttons, the video signal is muted, and the selected audio input’s LED blinks.

Input 0 can be selected via RS-232 control only by using an SIS

command or by selecting Mute (shown here) from the User Mode section of the control program (if the MLS is used without an MLC). Selecting input 0 mutes the audio from inputs 1 through 4.

For all models the Aux/Mix audio input is always enabled and cannot be turned on or off from the front panel. The Aux/Mix

Troubleshooting

1. Connect the cables between the MLS and the A/V input

devices. Connect the provided power supply and a host computer, third party control system, or MediaLink Controller to the MLS’s MLC/RS-232 Power port. Connect the MLS to the display device (projector) and audio output device (tape deck, speakers).

2. Connect the control device (computer, control system, or

MLC 206), the A/V source devices, projector and audio output device to a power source and turn them on.

3. Start the MediaLink Control Program, and set up the MLS

(and the MLC, if one is used). See chapter four.

To set up the MLS 100 Series switcher you must use MediaLink Control Software version 2.0 or higher. See the second note on page 2-9. If the software version is below 2.0, download a new version of the software from the Extron Web site, www.extron.com.

4. Press an input button on the MLS, watch the MLS’s LEDs,

observe the display, and listen to the audio. 4a. If the input selection LED does not light when a

button is pressed, the MLS might not be receiving power. Check the wiring at the MLS’s MLC/RS-232 Power port.

• If the conductor assignments are not correct, the circuits may be damaged if power is applied to the wrong pole.

• If the wiring is correct, ensure that the power supply has been plugged in to a functional power source.

4b. If power is present at the MLS and at the input and

output devices, but nothing happens (an A/V switch is not detected) when a button is pressed:

• If a MediaLink Controller is part of the system, the MLC’s firmware may be too old. If it is older than version 1.04, contact Extron for a firmware upgrade.

The MLC to which the MLS 100 Series switcher is connected must have MLC firmware version 1.04 or higher. Use one of the following methods to find out the version levels of the MLC’s firmware and the control software.

• Connect the MLC’s RS-232 port to a computer or

RS-232 controller, and send an SIS command of Q to

3-4

the MLC. The MLC will respond with its firmware version.

• Connect the MLC’s RS-232 port to a computer, start

the MediaLink control software, and click on Help to display the software version, the MLC’s firmware version, and the MLS’s firmware version.

• The audio settings may be too low. Adjust the Aux/Mix level by turning the Aux/Mix Level adjustment on the front panel. Adjust each selectable input’s level by using SIS commands, a control system, or the Switcher (MLS) Config. part of the MediaLink Control Software.

• The input or output connectors may not be firmly attached to the MLS, or they may be miswired.

4b. If power is present, but sound from inputs 1

through 4 isn’t audible, and if changing the audio

volume and gain/attenuation settings does not resolve the problem, make sure that neither audio input 0 nor audio mute is selected. Use the SIS information (I) command or the MediaLink Control Program to determine the audio settings.

5. Call the Extron S3 Sales and Technical Support Hotline if the equipment still does not respond when the MLS’s buttons are pressed.

Error responses

When the MLS receives a valid SIS command, it executes the command and sends a response to the host device. If the MLS is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host. Error response codes and their descriptions are as follows:

E01 – Invalid input channel number (the number is too large) E10 – Invalid command E13 – Invalid value (the number is out of range/too large) E14 – Invalid for this configuration.

Using the command/response tables

The command/response tables on the next page list valid command ASCII codes, the MLS’s responses to the host, and a description of the command’s function or the results of executing the command. Unless otherwise indicated (as for the gain commands), upper and lower case characters may be used interchangeably in the command field.

Host-to-MLS 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 MLS determines that a command is valid, it executes the command and sends a response to the host device. All responses from the switcher 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.

MLS-initiated messages

When a local event such as a front panel selection or adjustment takes place, the MLS responds by sending a message to the host. No response is required from the host. The MLS-initiated messages are listed here (underlined).

Control Software for Windows

The included Extron MediaLink Control Program for Windows offers another way to control the switcher via RS-232 connection in addition to the Simple Instruction Set commands. The control program’s graphical interface includes input selection functions and some additional features that are only available through the software.

To set up the MLS 100 Series switcher you must use MediaLink Control Software version 2.0 or higher.

The control software is compatible with Windows 95/98, Windows NT, and Windows 2000. Extron’s MediaLink Control Program is included with the MLS, and updates can be downloaded from the Extron Web site (http://www.extron.com).

Installing the software

The control program is contained on a set of 3.5-inch diskettes; it requires approximately 2 MB (megabytes) of hard disk space.

To install the software on the hard drive:

1. Run SETUP.EXE from the floppy disk.

2. Follow the instructions that appear on the screen.

By default the installation creates a C:\MediaLnk directory, and it places two icons (MediaLnk Control Pgm and MediaLnk Help) into a group or folder named “Extron Electronics”.

Using the control program

The MediaLink Help Program provides information on settings and on how to use the control program itself. Some features are only available via this control program. These features are described in the sections of this chapter that correspond to the parts of the control program where the features are found.

1. To run the control program, double-click on the MediaLnk Control Pgm icon in the Extron Electronics group or folder. The Comm Port Selection menu appears on the screen.

2. Click on the comm port that is connected to the MLS’s RS-232 port. The Extron MediaLink Control Program windows appear. The port and firmware information are displayed at the bottom of the screen. There are two views available: the User Mode screen, and the Switcher (MLS) Configuration screen.

User Mode

For stand-alone MLS 100 Series switchers

If an MLS 100 Series switcher is used without a MediaLink Controller, the User Mode screen, shown below, emulates the MLS’s front panel input selection buttons and also provides a means of volume control. See page 3-2 for details on basic operation.

Special features

Audio/video breakaway switching — To switch the audio sig-

nal separately from the video signal, check the Audio checkbox (at the right side of the I/O Switching area) and uncheck the Video checkbox, then select an input. The MLS switches to that input’s audio and leaves the previously selected video source active. Audio breakaway is shown above: the video is from input 1 and the audio is from input 2. (The corresponding SIS command is 1&2$.)

To switch the video signal without changing the audio

source, check the Video check box and uncheck the Audio checkbox. See the picture at left. Selecting Mute selects input 0 (no input).

Volume Mute — Check this box (in the lower left corner) to

activate the audio mute (Amt) command. See page 4-4 for the corresponding SIS command.

For MLS 100 Series switchers controlled by an MLC

If the MLS 100 Series switcher is connected to and controlled by an MLC, the user mode screen will look something like what is shown in the picture below.

In this case, you must set the volume control in the Controller (MLC) Config section to “Switcher”, as shown at right.

Switcher (MLS) Config

The Switcher (MLS) Config screen, shown below, allows you to make adjustments without having to use the front panel controls.

In this part of the program you can:

• Set the per-input audio gain or attenuation.

• Set overall volume; this is the same as the User Mode volume adjustment.

• Set the RGB delay period (MLS 102 VGA model only).

• Reset the switcher to factory default settings.

Saving and restoring configurations

The MLS can be configured via RS-232 communication, and the configuration settings can be saved to a file for later use.

1. In the MediaLink Control Program, select File, then select

Save Configuration as... .

2. Save the file as

filename.MLK. An unlimited number of configuration files can be saved as long as each file has a unique file name ending in .MLK.

3. To retrieve the configuration from within the MediaLink Control Program, select File, then select Restore

Configuration from... . A set of all the switcher and audio

adjustment settings will be downloaded into the MLS.

4-114-10

Emulation mode

The MediaLink Control Program features an emulation mode so you can set up a MediaLink system before equipment is available on site. In emulation mode a MediaLink Controller is always included in the system. You select which MLS switcher and which control modules will be connected to the MLC. For a stand-alone MLS (without an MLC), connect the MLS directly to the host computer for setup rather than using emulation mode.

You can save the emulated settings to a configuration file, then load that configuration file to the switcher (or switcher and MLC) when equipment is available.

1. Start the control program by double- clicking on the MediaLnk Control Pgm icon in the Extron Electronics group or folder. The Comm Port Selection screen (shown at right) appears.

2. Click on the Emulate radio button, then click on OK. The Initialize Emulated MediaLink Configuration from... dialog box appears.

3. Because you will be creating a brand new configuration,

select Cancel instead of selecting a driver file.

The Save

Emulated MediaLink Configuration as... dialog

box appears.

4. Enter a filename of your choice for storing the configuration

settings, then select Save.

The

Emulation Configuration

dialog box appears.

configuration file. This includes adjustments/ settings. If the MLS is connected to an MLC 206, the file will also contain whatever driver (if any) was installed in the MLC 206 at the time the file was saved. See the Media-

Link Controllers User’s Manual for details.

5. Select the MediaLink equipment that will be part of the system you want to configure, then click on OK. The Extron MediaLink Control Program windows appear.

6. Select the desired settings in each section of the program.

If you include an MLC 206 in the system, keep in mind that IR learning cannot be performed in emulation mode. You must have an MLC connected to the host computer.

7. To save the configuration for future use, follow steps 1 and 2 on page 4-10.
