About this Manual

This manual contains information about the Extron RGB 190F, RGB 192, and RGB 198 universal interfaces, detailing how to operate and configure them. The three interfaces are functionally identical, with the exception of the audio capabilities of the RGB 192 and RGB 198. All interfaces are described in this manual; differences are noted where they exist.

About the RGB 190F, RGB 192 and RGB 198

The RGB 190F, RGB 192, and RGB 198 are analog computer- video interfaces with 300 MHz (-3 dB) video bandwidth and Digital Display Sync Processing™ (DDSP™). Figure 1-1 shows a typical RGB 198 application; as noted above, the RGB 190F and the RGB 192 have a similar setup. The interfaces accept a computer video and an unbalanced computer stereo audio input. They feature a local monitor output and an RGBHV, RGBS or RGsB output. The interfaces feature horizontal centering and level boost. The RGB 192 and RGB 198 also feature a balanced, line level stereo or mono audio output.

Figure 1-1 — Typical RGB 198 application

All three interfaces allow for furniture and under-desk mounting. The RGB 198 is rack mountable as well. The

RGB 190F and RGB 192 have external switching power supplies for worldwide power compatibility, while the RGB 198 provides an internal power supply.

Each RGB interface has two or more model options:

Three RGB 190F models

•RGB 190FV for PC computers

•RGB 190FM for Macintosh computers

•RGB 190FS for SGI computers

Two RGB 192 models

•RGB 192V for PC computers

•RGB 192S for SGI computers

These two models are otherwise identical with the exception of the video input cable supplied.

Two RGB 198 models

•The RGB 198 provides an AC outlet with two Edison plugs.

•The RGB 198 EU provides an AC outlet with two Euro plugs for European markets.

With the appropriate cable adapters, both of these models are compatible with Macintosh computer and SGI computers.

Features

Flexible mounting options — The interface can be mounted under a desk or podium, mounted on a rack (RGB 198 only), or through a desk with optional mounting kits.

Stereo audio (RGB 192 and 198 only) — The interface outputs unbalanced PC stereo audio as line level, balanced stereo (or, depending on a DIP switch position, mono).

Level (boost) control — A front panel control compensates for signal losses from long cable runs.

Horizontal centering control — A front panel control allows a horizontal centering adjustment.

Sync processing — Using regular sync processing to allow centering control (H-shift) can create problems with some digital display devices as a result of the sync delay. Extron’s DDSP (Digital Display Sync Processing), ensures proper displays without altering sync pulse timing or width. The sync processing type is selected via the front panel DIP switches.
