Introduction

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.

Figure 1-1 — DDS 402 digital display scaler

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.

1-3Digital Display Scaler • Introduction

The scaler also features a zoom function, up to 200%, that maintains the original

aspect ratio. The zoom function makes the scaler ideal for video wall applications

using four displays and four DDS 402s zoomed to 200%.

The scaler features four levels of horizontal filters, which help prevent detail loss,

and ten levels of vertical filtering, which reduce flicker.

Other picture controls that the DDS 402 provides are centering, size, brightness,

and contrast adjustments. The scaler also has a top and bottom line blanking

function.

The DDS 402 is housed in a rack-mountable, 1U high, 17.5" wide metal enclosure.

With the included mounting brackets, the scaler can be rack mounted, or mounted

under a desk or table, or against a wall or the side of a desk. The DDS 402 has an

internal 100VAC to 240VAC, 50/60 Hz, 30 watts auto-switchable power supply that

provides worldwide power compatibility.

Features

Inputs — The DDS 402 switches between two inputs: Input 1 accepts computer

video on a 15HD connector, Input 2 accepts high resolution RGBHV, RGBS,

RGsB, or component video on five BNCs.

Introduction, cont’d

Digital Display Scaler • Introduction1-4

Operational flexibility — Operations such as input and scaling selection, picture

controls, and saving and recalling of presets can be performed on the front

panel or over the RS-232 link. The RS-232 link allows remote control via a PC

or control system. Input selection is also available under contact closure

control.

• Front panel control — The scaler front panel controller supports individual

input selection. The front panel features large, positive touch, illuminated

buttons that can be labeled with text or graphics, two rotary knobs for

making adjustments or selecting menu options, and an LCD.

• Windows-based control program — Extron’s Windows-based control

program provides a versatile range of operational options with its graphical

interface and drag-and-drop/point-and-click operation.

• Simple Instruction Set (SIS™) control — The remote control protocol uses

Extron’s SIS for easy programming and operation.

• Contact closure control — The operator can select either input via contact

closure through the Remote port.

Accu-RATE Frame Lock™ (AFL™) — A technology exclusive to Extron that solves

frame rate conversion issues experienced by video scalers. When video input

and output refresh rates differ, occasionally the two rates cross over each

other. The result is a glitch or image freeze on the display. AFL solves this

problem by locking the output frame rate to the input frame rate.

3:2 pulldown detection for NTSC video sources — This advanced, patent pending,

film mode processing feature helps maximize image detail and sharpness for

video sources that originated from film. When film is converted to NTSC

video, the film frame rate has to be matched to the video frame rate in a

process called 3:2 pulldown. Jaggies and other image artifacts can result if

conventional deinterlacing techniques are used on film-source video. The

DDS 402’s advanced film mode processing recognizes signals that originated

from film. The DDS 402 then applies video processing algorithms that

optimize the conversion of video that was made with the 3:2 pulldown

process. This results in richly detailed images with sharply defined lines.

Test patterns — The switcher features built-in test patterns to aid in monitor or

projector set-up and evaluation.

Blue mode — The switcher can be set to output the blue video signal only, to help

installers calibrate the monitor or projector.

Triple-Action Switching™ (RGB delay) — RGB delay blanks the screen when the

scaler switches between inputs. The new sync signals precede the RGB

signals, so that a noise-filled scramble is not shown during the transition.

The time delay between the RGB and sync signals is user adjustable up to

five seconds on the front panel and under RS-232 control.

Horizontal and vertical detail — The DDS 402 offers four levels of horizontal detail

and eight levels of vertical detail. Horizontal and vertical detail minimize the

loss of picture fidelity.

Picture controls — Horizontal and vertical centering, horizontal and vertical sizing,

brightness, contrast, zoom, and detail controls are available for fine picture

adjustments.

Top and bottom line blanking — Extron’s exclusive variable horizontal blanking

feature allows the operator to add black lines at the top and bottom edges of

the image to mask the top and bottom each image.

1-5Digital Display Scaler • Introduction

Freeze mode — Locks the output display to the selected image. Once an input is

frozen, the input can be removed without losing the output image. This

feature lets the DDS 402 function as a still store.

Auto memories — The two inputs support 32 auto-recall memories each, based on

the incoming frequency. Information on sizing, centering, detail, contrast,

and brightness is saved.

Front panel security lockout — Locks out all front panel functions except the input

selection and centering controls. When the front panel is locked, all functions

are still available via RS-232 commands.

Mounting flexibility — Mounting brackets make the 1U high scaler mountable in

any conventional 19” wide rack, or under or through a desk or other

furniture.

Power — The 100VAC to 240VAC, auto-switchable, internal power supply of the

DDS 402 provides worldwide power compatibility.

Video input connections

Input 1 (computer video) input (top) connector — Connect computer or RGB

video to this female 15HD connector.

Input 1 (computer video) loop-through (bottom)

connector — Connect a local monitor to this female 15HD

connector. The scaler buffers the computer video input

and loops it on this connector.

The Digital Display Scaler buffers the computer video input signal before

passing it to the loop-through connector. Beyond that, it does not alter the

loop-through video in any way. The loop through output is the same

resolution and frequency as the computer video input.

Input 2 (RGB or component video) connectors — Connect RGBHV, RGBS,

RGsB, or component video (R-Y, Y, B-Y for YUVi or YUVp, or Betacam) to

these female BNC connectors (figure 2-3).

Ensure that the correct Input 2 video format is selected from the front panel

menu, see Input #2 submenu, in chapter 3, Operation, or via the RS-232

port, see chapter 4, Programmer’s Guide, and chapter 5, Scaler Software.

See chapter 4, Programmer’s Guide, for definitions of the SIS commands and

chapter 5, Scaler Software to install and use the control software.

Contact closure connection

Remote port — The Remote connector also provides a way to select an input

using a remote contact closure device. Contact closure control uses pins on

the Remote connector that are not used by the RS-232 interface (figure 2-5).

To select a different input number using a contact closure device, momentarily

short the pin for the desired input number to logic ground (pin 5). To force

one of the inputs to be always selected, leave the short to logic ground in

place. The short overrides front panel input selections.

Power connection

AC power connector — Plug a standard IEC power cord into this connector

to connect the scaler to a 100 to 240VAC, 50 Hz or 60 Hz power source. The

front panel control and input selection buttons light in sequence during

power-up, the LCD displays the product name and then cycles through the

default messages.

Configuration

DDS 402 can be configured using either the front panel controls, the SIS, or the

Windows Control program. See chapter 3, Operation, chapter 4, Programmer’s Guide,

and chapter 5, Scaler Software for more information.
