Introduction

About This Manual

This manual contains information about the RGB 138xi and RGB 158xi 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 138xi and RGB 158xi

The RGB 138xi 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 138xi and RGB 158xi interfaces. See the installation chapter for a detailed description of front and rear panel features.

RGB 138xi 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 138xi and RGB 158xi 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.

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 138xi 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 138xi 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 158xi 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.
