Setting RGB delay (CrossPoint 450 Plus switchers only)

The CrossPoint 450 Plus switchers can briefly blank the RGB (video) output while it switches to the new input’s sync source, and then switches the RGB signals. This allows a brief delay for the display to adjust to the selected input’s sync timing before displaying the new picture, which will appear without glitches. RGB delay, also known as Triple-Action Switching or video mute switching, is user selectable from 0 to 5 seconds, in half-second increments.

The RGB delay interval can be set on the front panel or by using either serial port or the Ethernet port and either the SIS, Windows control program, or HTML pages (see chapter 4, “Programmer’s Guide”, chapter 5, “Matrix Software”, and chapter 6, “HTML operation”. Specify the RGB delay interval for a specific output on the front panel as follows:

RGB delay is protected when front panel lock mode 2 is selected. You can view the delay in lock mode 2, but not change it from the front panel.

1.	Press the Esc button to clear any input buttons, output buttons, or control
	buttons that may be lit.
2.	To enter RGB Delay mode, press and hold the RGBHV button until the button
	begins to blink green, then release the button.
3.	Press and release an output button to select an output. Each lit input button,
	from Input 1 through Input 10, indicates a half second of RGB delay interval
	for the selected output.
4.	Press and release the Esc ( ) and View ( ) buttons to increase and decrease
	the interval.
5.	Press and release the RGBHV button to exit the RGB Delay mode. The
	RGBHV button stops blinking.

• Pressing the Enter or Preset button also exits RGB Delay mode. Pressing the Preset button changes to Recall Preset mode.

•The RGB interval for each output is stored in non-volatile memory. When power is removed and restored, the delay settings are retained.

•Exiting RGB Delay mode by pressing the RGBHV button always returns the I/O configuration to audio only selected for configuration.
