About this Manual

This manual contains installation, configuration, and operating information for the Extron DDS 402 digital display scaler.

This chapter identifies the scaler’s features. Chapter 2 details how to install the scaler. Chapter 3 describes how to operate the scaler and use all of its features. Chapter 4 provides information about programming the scaler under RS-232 control, such as from a PC or a host controller. Chapter 5 details the Extron control software for Windows, which allows you to operate the scaler from a PC in a graphical environment. Appendix A lists the scaler’s specifications and pertinent part numbers and provides procedures for performing updates and repairs.

About the Scaler

The DDS 402 is a two-input digital display scaler (figure 1-1). The scaler inputs high-resolution RGBHV/RGBS/RGsB video on a 15HD connector (Input 1) and either RGBHV/RGBS/RGsB video or component video signals on five BNC connectors (Input 2). Input 1 is buffered, looped through, and output on a 15HD connector for use by a local monitor. The DDS 402 scales the selected input up or down to any 1 of 41 output resolutions and rates and outputs the video as both RGBHV or RGBS video and HD component video, on five BNCs and a 15HD connector. Several of the output resolutions and rates include Extron’s Accu-RATE Frame Lock™ (AFL™), a proprietary technology that locks the output frame rate to the input rate, solving the problems that result from different input and output rates. For home theaters, the DDS 402 features HDTV 720p, 1080p, and 1080i outputs.

For upscaling, the DDS 402 converts the horizontal and vertical sync timing and the number of lines of the lower-resolution RGB input to match the native resolution of the display. This produces an undistorted, brighter picture.

For downscaling, the DDS 402 accepts any computer resolution, up to 1600 x 1200, with horizontal scan rates up to 100 kHz and vertical scan rates up to 120 Hz, and converts the input to match the native resolution of the display.

The scaler is ideal for displaying images on projectors with limited display resolutions, such as liquid-crystal display (LCD) projectors, digital light processor (DLP) projectors, and plasma projectors.
