Troubleshooting

This section gives recommendations on what to do if you have problems operating the switcher.

1.Ensure that all devices are plugged in and powered on. The switcher is receiving power if any of the front panel button indicators are lit.

2.Check to see if one or more outputs are muted.

3.Ensure an active input is selected for output on the switcher.

4.Ensure that the proper signal format is supplied.

5.Check the cabling and make corrections as necessary.

6.Call the Extron S3 Sales & Technical Support Hotline if necessary. See the rear cover of this guide for the phone number in your region of the world.

Configuration Worksheets

Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 57 and use one for each preset configuration. Cross out all unused or inactive inputs and outputs. Use different colors for video and audio.

Worksheet Example 1: System Equipment

Figure 24 shows a worksheet in a fictional organization with the system hardware annotated. Input 3 and 7 and outputs 10 and 11 have no connections in this organization, so they have been crossed out on the worksheet.

Computer video group inputs include PCs, wall boxes and an Extron VTG 400. The low resolution video group inputs include cameras, a VCR, a DVD player, and an audio CD player. Computer video group output devices include monitors, projectors, a stereo, and a VCR for recording presentations. The low resolution video group includes low resolution monitors and audio tape,

The Extron VTG 400 video test generator connected to input 8 or to input 13 enables a video test pattern to be sent to one, several, or all output devices within the video group for problem isolation or adjustment purposes. An audio test tape or CD could be used in a similar manner to check out the audio components connected to the computer video and audio subgroup.
