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

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.
