Digital Display Scaler 1 Chapter One Introduction About this Manual About the Scaler Features
Introduction, cont’d 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.
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.
Introduction, cont’d 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.
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.

Digital Display Scaler 3 Chapter Three Operation Front Panel Controls and Indicators Front Panel Operations Optimizing the Video
Operation, cont’d Operation Front Panel Controls and Indicators All of the Digital Display Scaler’s controls and indicators are on the front panel (figure 3-1). The large, positive-touch, illuminated push buttons can be labeled with text and/or graphics. The buttons are fully illuminated green, amber, or red when selected. The 16x2 LCD display indicates the switcher status, and displays menu selections, the data rate, and the status of additional system features.
Memory presets with no values saved in them are not included in the loop; if preset 2 is empty, the loop sequences from preset 1 to preset 3 when the Input button is pressed. As each preset is recalled, the LCD displays the message Input x Memory y, where x is the input (1 or 2) and y is the preset (1, 2, or 3). The centering and sizing adjustments are tailored for the selected output rate.
Operation, cont’d 13 Adjust (vertical) knob — The Adjust knob changes settings when used in conjunction with the picture adjustment buttons or the menu system. Rotate this knob to change picture settings when one of the picture adjustment buttons is selected. In the menu system, rotate this knob to scroll through menu options and make adjustments. Button icons The translucent covers on the push buttons can be removed and replaced to insert labels behind the covers.

Programmer’s Guide The scaler’s rear panel Remote 9-pin D female connector (figure 4-1) can be connected to the RS-232 serial port output of a host device such as a computer running the HyperTerminal utility or a control system. This connection makes software control of the scaler possible.
Scaler-Initiated Messages When a local event such as power-up or a front panel operation occurs, the scaler responds by sending a message to the host. The scaler-initiated messages are listed in the following pages. The messages are underlined. Any time Reconfig The reconfig message is initiated by the scaler when a front panel operation has occurred or a memory preset has been recalled.

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.

Digital Display Scaler 5 Chapter Five Scaler Software Control Software for Windows Button-Label Generator
Scaler Software 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.

Reference Information, cont’d 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.
U24 U60 U67 U68 Figure A-2 — Locating the four firmware IC chips 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.
Reference Information, cont’d Button Labels 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).
