5Adjust knob (RGB 324, RGB 340) — Turning this knob adjusts the horizontal centering, vertical centering, video level, or audio level of the active buffer.

After the RGB 320 switches inputs, wait for the projected picture and the horizontal and vertical scan rates on the RGB 320’s LCD panel to stabilize before making adjustments. Adjustments made before the system stabilizes may not be stored in memory.

To make adjustments, follow these steps:

1.While the buffer is active (the Show Me/Select button/ LED is lit), press the Show Me/Select button. The H Shift LED lights to indicate that horizontal centering can now be adjusted.

2.Rotate the Adjust knob while viewing the displayed image to select the desired horizontal position of the picture.

3.Press the Show Me/Select button to activate the vertical centering adjustment. The V Shift LED lights.

4.Rotate the Adjust knob while viewing the displayed image to select the desired vertical position of the picture.

5.Press the Show Me/Select button to activate the video level adjustment. The Video Level LED lights.

6.Rotate the Adjust knob while viewing the displayed image to select the picture brightness.

7.Press the Show Me/Select button to activate the audio level adjustment. The Audio Level LED lights.

8.Rotate the Adjust knob while listening to the audio output to select the appropriate audio level.

9.Press the Show Me/Select button again or wait 7.5 seconds to exit the adjustment mode.

When an adjustment reaches a minimum or maximum limit, the buffer’s adjustment indicator ( 7 ) LED blinks.

The RGB 320’s LCD display indicates the adjustments that are being made from the buffer.

The buffer has priority over the RGB 320 and the RS-232 control device in terms of making adjustments. Adjustments to a buffer’s settings from the RGB 320 or the RS-232 control cannot take place while an adjustment is being made from the buffer itself.

buffer to the display/projector. If the request is granted, the buffer’s Show Me/Select button (RGB 324) or the LED next to the Show Me/Select button (RGB 340) lights. The LED corresponding to the input from this buffer will light

on the RGB 320.

If the RGB 320 is busy, the buffer’s Power LED will blink, and the Show Me/Select button must be pressed again to send the request.

Press the Show Me/Select button twice in succession to enter the adjustment mode. In adjustment mode you can make adjustments to centering and to audio and video levels by rotating the buffer’s Adjust knob.

Adjustment indicator LEDs – H Shift, V Shift, Video Level, Audio Level (RGB 324, RGB 340) — Each of these LEDs lights when that adjustment is selected. See 5 above.

Active LED (RGB 326) — This LED lights to indicate that the buffer has been selected (via the RGB 320’s front panel or an RS-232 control device), and it is providing the input to the display/projector.
