System reset to factory defaults

To reset the switcher to the factory default settings, press and hold the Esc button on the front panel while AC power is being applied. Continue to hold the Esc button until the power up sequence is completed (all LEDs turn off, the Video and Audio LEDs turn on, the Esc LED blinks, and the Power LED (if equipped) turns on). System reset clears all ties and presets, the RGB delay, the mutes, and the I/O grouping to the factory defaults and sets all audio gain levels to unity gain (+0dB).

Rear Panel Controls

The CrossPoint Plus matrix switchers all have sync termination switches on the rear panel for inputs 1, 3, 5, and 7 on the CrossPoint Plus 168 and 1616 models and inputs 1 through 4 (figure 3-20) on the CrossPoint Plus 84, 88, 124, and 128 models. The switches provide a way to condition non-TTL sync levels greater than 5Vp-p, enabling the sync to be properly passed from input to selected output(s). The matrix switchers have two sets of sync termination switches; one for horizontal or combined sync and a second set for vertical sync.

Figure 3-20 — Rear panel sync termination switches

Each switch provides the option of selecting either 510 ohms or 75 ohms. The 75 ohms position is required only for an input with non-TTL sync, greater than 5V p-p. The normal position is 510 ohms.

An input that produces an out of sync display, a display that is rolling vertically and/or tearing horizontally, could indicate a non-TTL sync input. A device that is known to output non-TTL sync levels (greater than 5V p-p) should be connected to one of the inputs with sync termination switches, and the switches for that input should be set to the 75 ohm position. If you’re not sure, check the specifications in the user’s manual for the input device.

Troubleshooting

This paragraph gives recommendations on what to do if you have problems operating the CrossPoint Plus, and it provides examples and descriptions for some image problems you may encounter.

General checks

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 S3 Sales & Technical Support Hotline if necessary.
