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.
Computer video loop-through connector — The computer video input, Input 1, is
buffered, looped through, and output for use on a local monitor on a 15HD
connector.
Outputs — The DDS 402 scales images to the following output resolutions:
640 x 480 (VGA) at 50 Hz, 60 Hz, 75 Hz, and lock*
800 x 600 (SVGA) at 50 Hz, 60 Hz, 75 Hz, and lock*

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.

Contact closure connection
6
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
7
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, Programmers Guide,
and chapter 5, Scaler Software for more information.
