Features Defined

Auto Power – In normal operation, the RGB 202xi is “green” or in “power saver mode” because it turns on only when it is needed. If it senses computer sync on its selected input, the RGB 202xi turns ON. Also, when the selected input senses no sync from that computer, it turns itself OFF. The LED lights when the RGB 202xi power is on.

Level and Boost – This control is similar to a contrast adjustment on a data monitor, which is used to adjust the brightness and contrast of the displayed image. This feature is also used to boost the output signal to a maximum of 1.45 volts peak to peak to compensate for losses of signal level or picture contrast due to cable length. Output cable lengths of up to 1000 feet can be used by adjusting this feature properly. The result is also dependent on signal frequency.

Peaking (Sharpness) Control – This control is similar to the sharpness control on a data monitor. Computer signals will have a sharper image when adjusting the peaking, regardless of the cable length. The peaking adjustment compensates for mid and high frequency RGB Video Bandwidth response in data monitors and projectors and for signal loss due to cable capacitance.

Vertical Picture Centering (with Memory) – This adjustment shifts the displayed image vertically on the monitor or projector screen and remembers the settings for both Input #1 and Input #2 separately.

Horizontal Picture Centering (with Memory) – This adjustment is used to position the displayed image from side to side on the screen. It also remembers the settings for both Input #1 and Input #2 separately.

Scan Rate Readout – This LCD readout alternately displays both the horizontal and vertical scan frequencies of the selected computer signal.

Internal Power Supply – A 90-270 Volt, 50/60Hz internal power supply is a standard feature of the RGB 202xi. No setup is required for 50/60Hz power sources.

Blue Enhance (TTL) – Allows for mixing just the right amount of blue video with the green video for displaying blue text in a more readable blue-green color. This color mixing affects only the displayed blue colors for TTL Computer-video signals.

Rear Panel Operation

Remote – Allows connection of a constant contact switch for remote selection

of Input #1 or #2 — only if Input switch on front panel is in #1 position.

MBC Power (2 connectors) – Connect Power plug(s) from up to 2 MBC Buffer cables.

Input #1, Analog/TTL – Connect a video cable (or MBC) from any Analog or

TTL source.

Input #2, Analog/ECL – Connect video cable (or MBC) from any Analog or ECL source.

Audio Input (1 & 2) – Connect to stereo audio sources for Input #1 and for Input #2 (above).

Audio Output (L & R) – Connect to stereo left & right inputs of an external audio system.

DIP Switches: (On = press right side of the switch, or away from the printed switch numbers;

Off = press left side.)

1 - Off = Normal sync processing; On = Use LCD Sync processing ( & become inactive).

2 - Off = Auto Sync detection; On = Auto Sync detection, but No Sync on Green.

3 - On = Force separate Horizontal & Vertical Sync; Off = Auto Sync.

4 - Off = Auto Power detect; On = Auto Power defeat (forces power On).

5 - Off = Allow Serrations; On = remove Serrations.

6 - Off = Normal vertical sync width;

On = Vertical Sync approximately twice normal width. 7 - Off = High Z, Input #1; On = 75 ý Impedance, Input #1. 8 - Off = High Z, Input #2; On = 75 ý Impedance, Input #2.
