Configuration Jumpers

The general illustration here shows an example of a 3-pin
jumper. These are sometimes called “Bergs”. There are
three possible combinations for a 3-pin jumper:

Pins 1 and 2 – Press the jumper onto pins 1 and 2.

Pins 2 and 3 – put the open end of the jumper over pins 2

and 3 and press on.

No connections (Open) – This can be done any way, as

long as no pins are connected. Three different Open
connections are shown here. Connecting one side of
the jumper and leaving the other contact off the end, or
off the side, is a common way to do this. This way, the
jumper is available if it is needed in the future.

Reference Information Troubleshooting

About this manual

This manual was written to explain the features,
installation and operation of Extron’s RGB 202xi series of
interfaces. Although the name “RGB 202xi” is used
throughout the manual, it refers to four different interface
models. Chapter 4 covers the differences between the
standard model RGB 202xi and those models with
special features.

Introduction to RGB Interfaces

As you may know by now, an RGB interface provides the
means for getting a computer video output to display on a
large screen. The interface must take the video signals
from the computer and transform them for use by a
projector or data monitor.

In addition to this, the RGB 202xi has many other
enhancement features. This user’s manual provides the
technical information required to install and operate the
RGB 202xi Universal Interface. Some places in this
manual it is simply referred to as the “interface”.

Interface Considerations

As illustrated above, the interface operates between a
computer (or computers) and a video projector.
Computers differ both in the type of video signals as well
as the physical connectors they use.

Adapters – For this reason, a universal interface requires an

adapter to match the physical and electrical connections
of the computer and the interface.

Local Monitor – Another thing that must be considered is

whether the computer's monitor (“local monitor”) will be
used in the application. This is more convenient for the
computer operator, or presenter because it may be
difficult to see the big screen while operating the
computer. If the local monitor is to be used, a Monitor
Breakout Cable (MBC) is required. An MBC adapts the
computer to the local monitor, as well as the interface.

Problem

Double image on
Data Display.

Vertical Jitter of
Displayed text.

Image on Data
Display is dim or
not at full
brightness level.

Image on Data
Display is too
bright.

Unstable image
on Data Display

Severely or
unreadable image

Probable Cause

1. The Horizontal scan
frequency of the
computer may be twice
that of the Data
Display.

1. Computer Source is
Interlaced.

1. Input voltage level is
too low.

2. Double Termination
at that input (1 or 2) of
the RGB 202xi.

1. No Termination for
that input.

2. Output level is too
high.

1. Sync on Green with
high sync levels on
short cable runs.

2. Serration Pulses are
present at the output.

3. Signal not terminated
at projector.

Signal needs horizontal
clamping.

Solution

1. Incompatibility of Data Display
with computer scan frequency.

1. Turn DIP switch #1 ON (LCD
sync processing).

1. Increase level using Level
Control on front panel. Turn the
knob clockwise.

2. Set termination switch (#7 for
Input #1, or #8 for Input #2) on
Rear Panel OFF for High Z.

1. Connect a local monitor to the
Extron MBC cable monitor input
connector (female).
or ­Set termination DIP switch ON
(#7 for Input #1; #8 for Input #2).
or ­See MBC documentation.

2. Adjust the Level/Boost
counterclockwise.

1. Make sure that Peaking Control
is fully ccw for short cable runs.

2. Turn DIP switch (#5) ON to
remove the Serration Pulses.

3. See projector documentation on
termination.

Troubleshooting Reference Information

Introduction • Features and Specifications

Due to the number of different types of Data Projectors
and Data Monitors currently on the market, each with
different characteristics, no specific data display device
was used to generate this troubleshooting information. If
you have a concern or would like to know any special or
unusual characteristic of your particular display, please
call Extron.

Problem

No image on Data
Display (projector
or monitor).

Probable Cause

1. Power Connections
not being made.

2. Data Display not set

phase is shifted too far
in one direction.

5. Level Control turned
down too low on
interface.

6. Sync on Green
output from interface.

7. Input select switch
on interface is not set
correctly.

Solution

1. Check to make sure power is
being supplied to the computer,
monitor, interface and Data
Display (and MBC cable if
required).

2. Check to confirm that Data
Display input settings are for
Analog.

3. Check and secure all cable
connections.

4. Turn DIP switch #1 ON to check
centering reference.

5. Adjust Level Control to the
middle position.

6. Set Data Display for an input of
Sync on Green, or turn Dip switch
#2 on to defeat Sync on Green
and #3 ON to use Auto Sync.

7. Make sure that the RGB 202xi

Introduction • Features and Specifications

Reference Information Quick Reference Guide

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.

REMOTE

1

2

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
