7.
Do nothing for approximately 30 seconds. The front panel times out and the
switcher exits I/O Group mode.
•
Group 1 consists of inputs 1 through 4 and outputs 1 through 4.
•
Group 2 consists of inputs 5 through 8 and outputs 5 through 8.
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 RS-232/RS-422
and Ethernet ports 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:
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 (
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.
The following steps show an example in which the RGB delay is increased for
output 17. The steps show the front panel indications that result from your action.
