Operating the RGB 202xi

This chapter covers the function of the controls and indicators on the RGB 202xi, including some examples on how they are used.

__ If there are any difficulties setting up for the desired results, see Appendix B for troubleshooting information.

Auto Power Indicator

This LED lights when the RGB 202xi is powered ON. “Auto Power” means that the computer signal will automatically turn the RGB 202xi power on.

If the LED does not illuminate, check for computer operation as well as cable and power connections.

If DIP switch #4 (rear panel) is On, the Auto Power detect feature is disabled, forcing the power ON as long as it is plugged to an active power source.

Level and Boost

This control is similar to a contrast adjustment on a data monitor or projector. It can be used to increase the brightness and contrast of the displayed image. Observe the displayed image while using these adjustments.

Following are some examples of approximate output levels, with a computer input signal (such as VGA) of .7 volts peak to peak (p-p) and the output is terminated at 75 ý.

1.With the knob in the minimum (counterclockwise) position, the voltage output level will be approximately 0.5 volts p-p.

2.With the knob to the end of the level adjustment range (at the top of the red line), the voltage output level will be approximately the same level as the input (0.7 volts p-p for this example).

3.At the full clockwise position (past the red line), the output can be increased up to 1.45 volts p-p.

RGB 202xiModel Differences

RGB 202 VS2 (VideoShift™)

The VS2 model includes Extron’s VideoShift™ feature. The front panel for the RGB 202 VS2 is shown below. The section marked “VideoShift™” includes a 3-position toggle switch to do the following:

Off – disables the feature.

Test – enables VideoShift™ at a rate fast enough to see movement on the screen. Use this position to adjust the shift range.

Shift – enables the feature.

When VideoShift™ is enabled, it prevents phosphor

“burn-in” by moving the displayed image around on the screen. The movement is so slow that it cannot be

detected by the human eye.

VideoShift movement to the right, down, to the left, up, etc. The distance of the shift, or movement depends upon the Range setting. The vertical

shift is in number of lines while the horizontal shift is in units of

time. Approximate settings are:

Minimum setting:

Vertical shift = 8 scan lines

(4 up and 4 down from center) Horizontal shift = 0.1 µsec.

Mid-range setting:

Vertical shift = 16 scan lines

Horizontal shift = 0.68 µsec.

Maximum setting:

Vertical shift = 32 scan lines

Horizontal shift = 1.28 µsec.

The actual horizontal distance will depend upon the video format. Here are two examples at maximum range:

SGI – 128 pixels VGA3 – 64 pixels
