About this Manual

This manual documents three dedicated RGB interface
units: the RGB 103xi, the RGB 109xi, and the RGB 112xi.
Unless otherwise specified, references to “the interface” in
this manual pertain to the features or operation of all three
interfaces.

About the Interfaces

All three dedicated interfaces have the same features, but
each was designed to work with a specific type of
computer.

The RGB 103xi is a high-resolution, dedicated Mac, Quadra,
Performa, PowerBook, and PowerMac computer-video
interface. It uses a 15-pin D-sub connector.

Features

Each interface includes the features listed below. See “Front
and Rear Panels” on page 2-2 for information about the
controls.

ADSP™ (Advanced Digital Sync Processing™) — Allows

sync processing operations, such as horizontal
centering, to occur without affecting the signal’s sync
timing. This allows horizontal centering to be
applied to signals that are output to digital display
devices, such as LCD projectors, DLP (digital light
processing) projectors, and plasma displays.

Auto power — Turns on power to the interface

automatically when a video signal is received from
the computer. You can determine that the interface is
on if the scan rate indicator LCD text is visible.

Buffered local monitor output — Allows you to view the

displayed image on a local monitor located up to 150
feet from the interface without signal reflections or
crosstalk.

Horizontal shift — Allows you to adjust the horizontal

placement of the image on the screen. Also called
“horizontal centering”.

Gain/peak control — Increases video signal voltages to

compensate for signal degradation caused by long
cable lengths.

Scan rate indicator LCD (liquid crystal display) —

Displays the horizontal and vertical sync frequencies
of the computer, and the minimum and maximum
points of adjustments to horizontal shift.

1-2

For each RGB 103xi and each RGB 112xi, Extron
provides a multi-frequency termination adapter
(MFTA) to be used if there is no local monitor. The
adapter is attached by a chain to the interface, and
an instruction card is attached to the adapter.

RGBS or RGBHV, depending on how the
interface and projector are cabled.

2 — DDSP (Digital Display Sync Processing™)

ON — If this switch is set to On, the interface

does not perform sync processing. This
may be necessary for digital display
devices, such as LCD (liquid crystal
display), DLP (digital light processing),
and plasma displays.

OFF — If this switch is set to Off, the interface

performs sync processing operations,
such as horizontal shift, using Extron’s
ADSP.

Turning on the DDSP feature disables the
horizontal shift control.

3 — SERR (serration pulses)

Many display devices, such as LCD and DLP
projectors and plasma displays, must have
serration pulses removed from the sync signal in
order to display images properly. Flagging or
bending at the top of the video image is a sign
that the serration pulses should be removed.

ON — If this switch is set to On, serration pulses

are present on the output signal.

OFF — If this switch is set to Off, serration

pulses are not present on the output
signal.

(sync polarity) or J40 (vertical sync width). See
“Setting internal jumpers” below.

Set up the configuration switches. See “Setting

4

configuration switches” on page 2-9.

If desired, attach the interface to a table or under a

5

podium using an optional Extron mounting kit. See
“Mounting the interface” on page 2-9.

Attach the interface to the computer, attach the local

6

monitor to the interface, and attach the projector to
the interface. See “Cabling” on page 2-11.

If you are not using a local monitor with the
RGB 103xi or the RGB 112xi, you must attach an
MFTA (multi-frequency termination adapter) to
simulate a monitor.

Attach the interface to an audio system. See

7

“Connecting audio” on page 2-12.

Plug the interface into a grounded AC power source.

8

Turn on the computer, monitor, and projector (or

9

other display device).

The image from the computer should appear on the

10

projector and monitor. If it does not, double check
steps 4 through 6 and make adjustments as needed.

Setting internal jumpers

The jumpers inside the interface are set at the factory for
optimal use by most systems. However, you can change a
jumper setting to meet the needs of a particular system.

Changes to internal jumper settings must be
performed by authorized service personnel

only.

The user-configurable, internal jumpers control the
following functions:

J20: Sync polarity jumper — This jumper adjusts the

Negative

Follow

1

• If the jumper is on pins 1 and 2, output H and

output sync polarity. Horizontal
(H) and vertical (V) sync output
can either follow input sync
polarity, or be forced to negative.

V sync polarities are forced to negative.

• If the jumper is on pins 2 and 3, output sync
polarities follow input sync polarity: The
output sync signals’ polarity is the same as
the input polarity. This is the default
setting.

J40: Vertical sync width jumper — This jumper

adjusts the vertical sync pulse width.

Wide

Short

Some digital display devices have very
specific requirements for incoming

1

sync pulse width. If no picture
appears, the picture cuts in and out, or the
picture is scrambled, try adjusting the vertical
sync pulse width or switching from ADSP to
DDSP.

• If the jumper is on pins 1 and 2, the output

vertical sync pulse will be short (narrow).

• If the jumper is on pins 2 and 3, the output

vertical sync pulse will be wide. This is
the default setting.

To change the jumper settings, do the following:

1. If the power cord is attached, remove power from the
interface by disconnecting the AC power cord from
the unit.

2. Remove the interface cover (the top half of the
enclosure), as shown in figure 6. Remove the screws
from the enclosure, slide the cover slightly towards
the back of the enclosure, enough to clear the gain/
peak switch, lift the cover, and place the cover
upside down next to the base of the enclosure.

Do not pull on the cable that attaches the cover
to the base. Doing so could disconnect the
cable from its connectors.

Do not touch any switches or electronic
components inside the interface. Doing so
could damage the interface.

Slide cover back slightly,
lift straight up.
