PRELIMINARY

Setting RGB delay (systems with wideband BMEs)

A switcher that includes a CrossPoint 450 Plus Sync BME can brieﬂ y 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, SIS Programming and Control, chapter 5, Matrix Software, and

chapter 6, HTML operation. Specify the RGB delay interval for a speciﬁ c 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 (

) 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.

N • 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 conﬁ guration to audio only selected for conﬁ guration.

Example 6: Setting the RGB delay for an output

In the following example, the RGB delay is increased for output 17. The steps show

the front panel indications that result from your action.

1. Press and release the Esc button (ﬁ gure 3-35).
