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.

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

Overall volume control ranges from 0% (90 dB attenuation) to 100% (0 dB attenuation). Adjustment increments are 1 dB for steps from 1% to 40% volume. Adjustments are in 0.5 dB increments from 41% to 100% of full volume.

Setup via the MediaLink™ Control/Configuration 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.

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 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.

Input gain and attenuation for audio inputs 1 through 4 is adjustable via RS-232 control only

(using SIS commands or the MediaLink Control/ Configuration Software.)

The Aux/Mix input level can be adjusted via the front

panel Aux/Mix Level control only. Aux/Mix level can not be adjusted via RS-232 (SIS commands,

configuration software, or an MLC MediaLink Controller). The Aux/Mix level is independent of the input and volume controls for the four switchable inputs.

Volume for the four switchable inputs is not adjustable via the front panel. It can be adjusted only via RS-232 (including via an MLC).

Wait at least ten (10) seconds between making a change (input selection or audio adjustment) and disconnecting power from the MLS. The switcher needs several seconds to store and save the new settings in its memory.

2-10

If you wire an audio output for balanced output, the MLS outputs 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 6 dB (gain =

-6 dB).

Front Panel Features and Operation

MLS 100 Series Front Panel (all models)

MLS 100 Series

INPUT SELECT

2 3 4

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 4), 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

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.

Wait at least 10 seconds between making a change (input selection or audio adjustment) and disconnecting power from the MLS. The switcher needs several seconds to store the new settings in its memory.

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 (-43 dB), the Aux/Mix signal is inaudible. You hear the maximum Aux/Mix volume when the control is turned to the clockwise limit (+24 dB).

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 SIS commands or the MediaLink Control/Configuration Software.) The gain and attenuation for the Aux/Mix input is adjustable only via the Aux/Mix Level control.

Wait at least 10 seconds between making a change (input selection or audio adjustment) and disconnecting power from the MLS. The switcher needs several seconds to store/save the new settings in its memory.

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 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).

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 4.

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

supply has been plugged in to a functional power source.

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 the MLC. The MLC responds 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/Configuration Software.

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

4c. 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/ Configuration 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.

The MediaLink switcher can be remotely set up and controlled via a host computer or other device (such as a control system) attached to the rear panel MLC/RS-232 Power port. Alternatively, the switcher can be controlled by an optional MediaLink Controller (MLC) (connected to the MLS’s MLC/RS-232 Power port), or by an RS-232 device acting through the MLC. The control device (host) can use either the Extron Simple Instruction Set (SIS™) commands or the graphical control/configuration program for Windows use and setup of a system that includes a MediaLink Controller, see the MediaLink Controllers User’s Manual.

RS-232 Programmer’s Guide

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).

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

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.

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 (shown at right) in

the lower left corner of the software window to activate the audio mute (Amt) command. See page 4-4 for the corresponding SIS command.

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 is downloaded into the MLS.

Emulation mode

The MediaLink Control/Configuration 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 the Emulate radio button, then click OK. The Initialize Emulated MediaLink Configuration from... dialog box appears.
