MVX Plus 128 VGA A Matrix Switcher • Operation
PRELIMINARY
Setting RGB delay
The switcher 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 then appears 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.
You can set the RGB delay interval on the front panel or by using the serial ports
and LAN port with 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:
N
RGB delay is protected when front panel lock mode 2 is selected. You can view
the delay in lock mode 2, but you cannot change it from the front panel.
1. Press the Esc button to clear any input buttons, output buttons, or control

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 (
>

the Preset button changes to Recall Preset mode.

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.
