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.
Digital Display Scaler • Introduction1-2
Features
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.
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*

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.
Digital Display Scaler • Introduction1-4
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.

Front Panel Operations
The following paragraphs detail the power-up process and then describe the menu system, the picture adjustments, and selection of executive mode.
Power
Power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the scaler performs a self-test that lights all of the front panel button indicators and then defaults to the selected input (lit). The Menu and Next buttons also light. The self-test also displays the model name and the firmware version in the LCD display. After approximately 2 seconds, the LCD reverts to its default display, cycling through displays of the selected input, the input rate, and the selected output rate (figure 3-3). An error-free power up self-test sequence leaves all of the button indicators, with the exception of the selected input, Menu, and Next pushbuttons, unlit and the LCD displaying the default display cycle.
The selected input, the picture adjustments, and other current settings are saved in non-volatile memory. When power is applied, the latest configuration is retrieved.
If an error occurs during the self-test, the switcher locks up and will not operate. If your switcher locks up on power-up, call the Extron S Hotline.

When one of the Picture Adjustments buttons (Center, Size, Brightness and Contrast, Zoom, or Detail) is pressed, the corresponding image adjustment menu appears on the LCD screen. Adjustments can then be made by rotating the
Adjust volatile memory; when the scaler is powered down and powered up, the settings are restored.
Adjust an image for centering, sizing, brightness, contrast, color, tint, zoom, or detail as follows (figure 3-10):

Optimizing the Video
Perform the following steps, in sequence, after you have installed the DDS. This procedure will help you to configure the scaler for the best settings for your display environment. In a multi-screen environment, perform this procedure for each display.
See Advanced Configuration menu earlier in this chapter to select and output a test pattern and to select and output blue only video.
See Picture adjustments, earlier in this chapter, to make adjustments to the picture quality.
See Memory Presets menu, earlier in this chapter to save presets.
1. If you are using a digital display, such as an LCD or DLP projector, use the
alternating pixels test pattern as a reference to adjust the phase and dot clock on the display devices. Proceed to step 3.
2. If you are using a CRT display, use the cross hatch test pattern as a reference
to converge the display.
3. Set the DDS to output either the crop test pattern for 4:3 video or the
appropriate aspect ratio test pattern. Use the display’s positioning controls to position the image so that you can see all sides of the test pattern on the display.
4. Select an input. Use the DSS’s size and center functions to fill the crop or
aspect ratio test pattern.
5. If the input source is RGB, use the horizontal and vertical detail adjustments
to increase the sharpness.
6. For RGB video inputs, set brightness and contrast levels. See Color/Tint,
Brightness/Contrast, Size, Center, and Detail adjustments, earlier in this chapter.
7. Save this setting into one of the user memories using the DDS Memories
menu.
Do not use the DSS’s center controls to position the image.
If the input source is a DVD, set the DVD player to output a 16:9 aspect ratio, see Setting up a DVD source below, before sizing the image using the DSS’s size function to correct the aspect ratio.
When sizing and centering a letterbox movie video source, increasing the brightness on the DDS makes it easier to see the top and bottom of the active video.
Setting up a DVD source
To get the best results when using a DVD as a video source, Extron recommends that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3. Because all DVDs are mastered as 16:9, having them set up for anything else causes the player to internally scale and compress the signal.
All sizing adjustments to correct aspect ratio should be done using the DDS. To change the output aspect ratio of most DVD players:
1. Enter the DVD player’s setup or action menu while the disc is stopped.
2. Select the 16:9 aspect ratio.

Host-to-Scaler Instructions
The scaler accepts SIS (Simple Instruction Set) commands through the Remote port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each scaler response to an SIS command ends with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.
Scaler Error Responses
When the scaler receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the scaler is unable to perform the command because the command is invalid or contains invalid parameters, the scaler returns an error response to the host. The error response codes are:
E01 — Invalid input channel number (too large) E10 — Invalid command E11 — Invalid preset number (too large) E13 — Invalid value (out of range) E17 — Illegal command for this signal type
Using the Command/Response Table
The command/response table begins on the next page. Except for the horizontal and vertical filter settings, upper or lower case letters are acceptable in the command field. The table below shows the hexadecimal equivalent of each ASCII command. Symbols, defined on page 4-2, are used throughout the table to represent variables in the command/response fields. Command and response examples are shown throughout the table.
ASCII to HEX Conversion Table

With the exception of the horizontal and vertical filtering (D and d) commands, the SIS commands are

Control Software for Windows
Two software programs accompany the DDS 402:
The Extron USPDDS Control Program, which communicates with the scaler via the Remote port, provides an easy way for you to control the scaler.
The Extron Button-Label Generator, which allows you to design and print labels to insert in the scaler front panel buttons.
Both programs are compatible with Windows 95/98, Windows NT, Windows ME., Windows 2000, and Windows XP. Updates to these programs can be downloaded from the Extron Web site (http://www.extron.com).
Installing the software
The programs are contained on a CD-ROM, and you should load and run the program from the hard drive.
To install the program from the CD-ROM to the hard drive, run SETUP.EXE from the CD-ROM and follow the instructions that appear on the screen. The program occupies approximately 2 Mb (megabytes) of hard-drive space.
By default the installation creates a C:\USPDDS directory, and it places three icons (USPDDS Control Pgm, USPDDS Help, and Button-Label Generator) into a group or folder named “Extron Electronics”.
Using the control program
Many items found in the USPDDS Control Program are also accessible via front panel controls and the LCD menus, see chapter three, Operation, and under SIS control, see chapter 4, Programmer’s Guide. The USPDDS Help Program provides information on settings and on how to use the control program itself.
1. To run the control program, double-click on the USPDDS Control
Pgm icon in the Extron Electronics group or folder. The Comm menu appears on the screen.
2. Click on the comm port that is connected to the DDS 402’s Remote port.
The Extron USPDDS Control Program window (figure 5-1) appears.

Button Label Generator
You may wish to customize the labeling of the DDS 402’s front panel buttons. Blank templates for the DDS 402’s button label windows are included in appendix A of this manual. However, you can easily create, customize, and print labels for the scaler’s button label windows by using the Button-Label Generator software.
The program is included on the same CD-ROM as the DDS 402 control program, and it can also be downloaded from the Extron Web site (http://www.extron.com). This program creates and prints labels that can be inserted into the illuminated push buttons on the scaler.
Installing the software
By default, the installation program installs the program in the C:\USPDDS directory, and the Button-Label Generator icon is placed in the “Extron Electronics” group or folder.
Using the software
1. To run the Button-Label Generator program, double-click on the
Button-Label Generator icon (shown at right) in the Extron Electronics group or folder, and click OK when prompted. The Extron’s Button-Label Generator window appears (figure 5-3).
2. Under System selection, choose System 7SC. This selection creates
the correctly sized labels for the DDS’s buttons. The button label editing area changes to reflect the number and arrangement of buttons on the device.
Figure 5-3 — Extron’s Button-Label Generator window
3. Using normal Windows controls, you can create and print labels that can be
cut out and placed in the label windows on the front panel of the USP.
For information about using the program, you can access a help file by clicking on the Help menu on the main screen and choosing Show Help.
You can also see an example of a completed Extron Button-Label Generator window by clicking on the Help menu on the main screen, choosing Show Help, and clicking on the Load Demo button.

Firmware Upgrade Installation
In some cases the DDS 402’s firmware may require replacement with an updated version. There are two user-replaceable firmware chips, U60 — the main microcontroller and U24, and one set of chips, U67 and U68. The chip set, U67 and U68, are replaced as a pair. The U-numbers are printed on the circuit board. We recommend that you send the unit in to Extron for service and updates.
Changes to firmware must be performed by authorized service personnel only. Some DDS 402 firmware updates must be performed at the Extron factory.
Replace firmware in the DDS 402 as follows:
1. Disconnect the AC power cord from the DDS 402 to remove power from the
unit.
To prevent electric shock, always unplug the DDS 402 from the AC power source before opening the enclosure.
2. Remove the DDS 402 from the rack or furniture.
3. Remove the cover of the DDS (the top half of the enclosure) by removing the
13 screws, 7 on the top and 3 on each side, then lifting the cover straight up (figure A-1).
Remove (13) screws from top and sides.

Figure A-1 — Removing the DDS 402 cover
Do not touch any switches or other electronic components inside the DDS 402. Doing so could damage the scaler. Electrostatic discharge (ESD) can damage IC chips even though you cannot feel it. You must be electrically grounded before proceeding with firmware replacement. A grounding wrist strap is recommended.
4. Locate the firmware chip(s) to be replaced on the circuit board (figure A-2).
5. For U67 and U68, after you are electrically grounded, remove the U67 and
U68 IC chip set (which must be replaced as a pair) by grasping each chip firmly with your fingers and

6. For U60 or U24, align the hooks of a PLCC IC puller tool with the slots
located in opposite ends of the firmware chip.
7. Insert the hooks into the slots, and squeeze the tool
gently to grasp the chip.
8. Pull the chip straight out of the socket, and set it aside.
9. For U67 and U68, align the slots of the new firmware
chip with the angled corners of the socket in the same orientation as the old chip. Gently, but firmly, press the chip into place in the socket.
10. For U60 or U24, note the key (angled corner) of the new
firmware IC and the dot on the underside that indicates pin 1 (figure A-3). Orient the IC to match the key and pin 1 (indicated by arrow) on the socket, and gently, but firmly, press the IC into place.

Figure A-4 provides blank button labels. If desired, photocopy them or cut them out of the manual, write button information in each button area as desired, and put them in the scaler ’s input buttons’ windows.
Installing labels in the scaler’s buttons
Install new labels in the scaler ’s front panel input buttons as follows:
1. Make new labels using either the blanks in
figure A-4 or the Button-Label Generator software (see the chapter 5, Scaler Software). Cut them out.
2. Remove the button from the scaler by grasping the
button firmly and pulling it away from the front panel.
3. Use a Tweeker to gently lever the button cap off of
the white backing plate.
4. Insert a button label into the cap and gently but
firmly press the cap onto the white backing plate.
5. P ress the button into place in the scaler.
