Introduction

About this Manual

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

About the Interfaces

Both dedicated interfaces have the same features, but each works with a specific type of computer.

The RGB 109xi is a high-resolution, dedicated VGA/XGA/ SVGA/SXGA computer-video interface. It uses a 15-pin HD connector.

The RGB 112xi is a high-resolution, universal workstation interface that is compatible with all workstations that use a 13W3 video connector, such as Sun, IBM PowerPC, SGI, and NeXT workstations.

For 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.

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 (liquid crystal display) 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 displays a scan rate.

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