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.
