Troubleshooting

This section gives recommendations on what to do if you have problems operating
the TPX switcher.
1. Ensure that all devices are plugged in and powered on. The switcher is
receiving power if one of the input LEDs is lit.
2. Ensure an active input is selected for output on the switcher.
3. Ensure that the proper signal format is supplied.
4. Check the cabling and make corrections as necessary.
5. Call the Extron S

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 3-31 and
use one for each preset configuration. Cross out all unused or inactive inputs and
outputs. If applicable, use different colors for video and audio.

Worksheet example 1: System equipment

Figure 3-47 shows a worksheet for a TPX 88 A in a fictional organization. System
hardware is annotated. Input 6 has no connection, so it has been crossed out.
Inputs include PCs, a CD player, cameras, and a VTG 300, all connected through TP
transmitters. Output devices include monitors, front and rear projectors, a stereo,
and a VCR for recording presentations, all connected through TP receivers.
The Extron VTG 300 video test generator connected to input 8 enables a video test
pattern to be sent to one, several, or all output devices 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.
