RGB 138 xi, RGB 158xi Introduction
Advanced Digital Sync Processing ™ (ADSP ™ ) — ADSP
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 projectors and
plasma displays. A rear panel DIP switch allows an
alternative, Digital Display Sync Processing
™
(DDSP ™ ), to be used instead.
Gain/peaking control — To compensate for signal
degradation caused by long cable lengths, use this
rear panel toggle switch to increase output voltages.
Serration pulse — This feature allows serration pulses to
either be present or not present at the output.
Serration pulses are required for some displays.
Pass-through connectors — A wide assortment
of architectural adapter plates is available for
installation on these interfaces to allow convenient
pass-through A/V connections.
RGB 138 xi features
MBC power jack — The power connector of a buffered
monitor breakout cable can be plugged directly into
the front panel jack on this interface.
Vertical shift control — The RGB 138 xi lets you adjust
vertical centering with a front panel knob.
75 ohm video termination — 75 ohm video termination
can be selected from a rear panel DIP switch.
RGB 158 xi features
Buffered local monitor output — A 15-pin HD female
connector provides a front panel buffered output for
a local monitor.
ID bit termination — Two front panel DIP switches
provide ID bit termination on pins 4 and/or 11 of the
local monitor output.

Introduction
About This Manual
This manual contains information about the RGB 138 xi and
RGB 158 xi universal analog interfaces and on how to
operate and configure them. Unless otherwise specified,
references to “the interface” refer to the features or
operation of both models.
About the RGB 138 xi and RGB 158xi
The RGB 138 xi and RGB 158xi are computer-video and
stereo audio interfaces with 300 MHz (-3dB) video
bandwidth. These interfaces have a horizontal frequency
range of 15 kHz to 125 kHz, so they can be used with any
type of analog computer signal, including those from VGA,
SVGA, XGA, SXGA, XGA-2, Mac, Quadra, Sun, and SGI
computers.
Features
This section highlights the main features of the RGB 138 xi
and RGB 158 xi interfaces. See the installation chapter for a
detailed description of front and rear panel features.
RGB 138 xi and RGB 158xi features
Internal power supply — Use standard IEC power cords.
Front panel AC outlet — Peripherals or laptop computers
can be plugged into the unswitched front panel AC
outlet for a convenient power connection. This feature
is not available in Europe.
Furniture and rack mountability — The RGB 138 xi and
RGB 158 xi can be mounted under a desk or podium
with optional hardware, or they can be mounted in a
rack or through a desk or other furniture with
included vertical mounting brackets.
Active stereo audio — Unbalanced stereo audio input via a
front panel jack is output as balanced, line level
stereo audio on the rear panel captive screw
connector.
Horizontal shift control — Both models feature front panel
horizontal centering control.
Sync stripping — Incoming sync will be stripped from the
red, green and blue signals.
RGBHV, RGBS or RGsB output — RGBHV can be output
simultaneously with RGBS. Sync on green (RGsB)
output can be DIP switch selected.
