About this Guide

The DSC 3G-3G A User Guide describes the Extron DSC 3G to 3G A Digital Scaling Converter and provides instructions for experienced installers to install, configure, and operate it.

In this guide the terms "scaler" and "DSC" are used interchangeably to refer to the DSC 3G-3G A.

About the DSC 3G-3G A

The DSC 3G-3G A is a 3G-SDI scaler that converts between 3G-SDI, HD-SDI, and SD-SDI resolutions and frame rates. It accepts, scales, and outputs SMPTE video resolutions from 480i and 576i up to 1080p @ 60 Hz and 2K. It provides 30-bit Deep Color processing for optimal image quality, 1080i de-interlacing, and analog audio embedding, de-embedding, and gain and attenuation adjustments. Other features include Auto Memory (automatic saving of the size, position, and picture settings of the current source device), Auto-Image (automatic sizing and positioning of the image on the display), and internal test patterns.

Setup and configuration are provided via front panel controls with an on-screen display (OSD), the Windows®-based Product Configuration Software (PCS) through a front panel USB Config port, and the Extron Simple Instruction Set (SIS) commands through the USB and RS-232 ports. The unit has a compact 1U high by half-rack wide by 8.5 inches (21.5 cm) deep enclosure and can be rack or furniture mounted.

The DSC 3G-3G A has one 3G-SDI/HD-SDI/SD-SDI input plus an SDI loop-through, and two simultaneous 3G-SDI/HD-SDI/SD-SDI outputs. It also features automatic input cable equalization and reclocking on a buffered SDI loop-through.

Features

• 3G-SDI video cross conversion — Provides high quality scaling and conversion of 3G-SDI, HD-SDI, and SD-SDI video resolutions and frame rates.
• Inputs:

- Video — One 3G-SDI/HD-SDI/SDI input and a buffered loop-through on BNC connectors.

- Audio — Balanced and unbalanced stereo audio input on a 5-pole captive screw connector.

- Outputs:

• Video — Two simultaneous 3G-SDI/HD-SDI/SD-SDI outputs on BNC connectors for driving two displays.
• Audio — Balanced and unbalanced stereo audio output on a 5-pole captive screw connector.

- SDI audio embedding and de-embedding — Analog stereo audio can be embedded onto the SDI outputs. Any pair of AES audio channels from the SDI input can be extracted to the analog output. Alternatively, any pair of AES audio channels, or all AES audio channels can be passed to the SDI outputs.

- Input equalization and reclocking — Automatically equalizes incoming signals and reshapes and restores signals on the buffered loop-through.

- Advanced scaling engine — Image scaling and video format conversion are performed at 30-bit precision for enhanced color accuracy and picture detail. De-interlacing for 1080i signals from HD sources delivers optimized image quality.

- Selectable output rates — Available output rates include 480i, 576i, HDTV rates up to 1080p @ 60 Hz, and 2K (2048x1080).

- Aspect ratio control — The aspect ratio of the video output can be controlled by selecting a fill mode, which provides a full screen output, or a follow mode, which preserves the original aspect ratio of the input signal.

- AFL - Accu-RATE Frame Lock — A patented technology exclusive to Extron that locks the output frame rate to a designated input to eliminate stuttering caused by frame rate conversion.

- Genlock input with loop-through — Allows for synchronization to an external reference signal and supports bi-level or tri-level sync for integration into broadcast and production applications.

- Front panel LED indicators — Provides visual indication of system status for real-time feedback and monitoring of signal format, presence, and power.

- Configuration software — The Windows-based PCS configuration program is available to be downloaded from the Extron website. This program lets you configure the DSC from your computer via a USB connection.

• Image freeze control — A live image can be frozen using USB or RS-232 control.

- Auto Memory — When activated, the unit automatically stores size, position, and picture settings based on the incoming signal. When the same signal is detected again, these image settings are automatically recalled from memory.

- On-screen menus — The OSD menus enable system setup using the front panel buttons. Key parameters such as input and output video formats are grouped for convenience on the initial Quick Setup screen, while additional screens provide full control over the other functions and settings.

- Output Standby Mode — Automatically mutes the video and syncs the output to the display device when no active input signal is detected. This allows the projector or flat-panel display to automatically enter into standby mode to save energy and enhance lamp or panel life.

- Power Save Mode — Places the unit in a low power standby state to conserve energy when not in use.

• Automatic 3:2 and 2:2 pulldown detection — These advanced film mode processing techniques help maximize image detail and sharpness for 480i, 576i, and HDTV 1080i sources that originated from film.
• Picture controls — Enable control of brightness, contrast, detail, horizontal and vertical positioning, overscan, and sizing.
• User presets — Presets are available for each input to store and recall optimized image settings.
• Internal test patterns — Offers a crop pattern, grayscale, color bars, alternating pixels, crosshatch, audio pink noise, and blue mode.

- Genlock/AFL — Select this item to enable or disable syncing of the video signal to the reference signal from an external sync device connected to the Genlock Sync input connector. Signals on the green wire of a component video device or an SDI genlock signal can be used for genlock.

This option also enables and disables the AFL (Accu-RATE Frame Lock), which locks the output vertical refresh rate to the vertical refresh rate of the selected input.

NOTE: Genlock and AFL lock the output refresh rate to similar input rates. If the input signal is locked on a rate that is not considered a standard SDI output or that is very different from the current output setting, the DSC may not output a signal. The image may not display or may blink.

To select the genlock or AFL mode, select Genlock/AFL from the Output submenu, then press any of the arrow buttons to step through the options. The choices are:

• Off — The output runs at the selected output frame rate using time base corrected frame buffers (default).
• Input AFL — The output is locked to the vertical sync of the input. This is valid only if the frame rate is an SMPTE video standard and the output frame rate is the same.
• SDI Genlock — The genlock input and loop-out are used for sync reference. The Genlock input supports bi-level and tri-level sync. The video output requires time base correction if the input source is of a different frame rate.

- SDI Genlock Offset — Select this item to adjust the horizontal and vertical offset of the genlock signal.

NOTE: This feature can be adjusted only if the DSC is in SDI genlock mode (SDI Genlock must be selected for the Genlock/AFL item).

The following options are available on the Advanced Configuration submenu:

- Test Pattern — This option lets you select a test pattern to use in setting up a display when outputting different resolutions. The following test patterns are available:

Figure 20. Test Pattern Options

NOTES:

• The Audio Test pattern displays a crop pattern with OSD text AUDIO TEST. It also outputs pink noise at 48 kHz, 24 bit.
• By default all test patterns except Blue Mode include a single pixel wide crop pattern line.
• Test pattern selections persist through a power cycle.

- Screen Saver and Timeout — Select this item to enable screen saver mode, in which the video output is muted to black or blue if there is no active input video signal. You can also specify the output sync timeout. Screen saver mode allows display devices (such as an LCD panel, plasma screen, or projector) to enter low power or standby state to increase panel or lamp life.

- To select the screen saver color, press the ◀ or ▶ button. The selections are Black (default) or Blue with an OSD message.

- To set the sync timeout, press the ▲ or ▼ button. You can select a duration of 0 to 500 seconds before the output sync times out. The default is Never, meaning that the sync does not time out.

NOTE: The DSC exits screen saver mode when the front panel Menu or Enter button is pressed or an active input is detected. If the unit is in front panel lock (executive) mode (see Locking the Front Panel (Executive Mode) on page 30), front panel button presses have no effect on screen saver mode.

- Aspect Ratio — Select this item to set the aspect ratio to Fill (fills the entire output screen) or Follow (follows the native aspect ratio of the input).

- In fill mode, if you want to set an aspect ratio adjustment for a single input rate, you can select the correct size and position manually from the Picture Controls submenu (Image Size and Position) (see Picture Controls submenu on page 18).

- In follow mode, each input rate is displayed with its native aspect ratio (4:3, 5:4, 16:9, or 16:10) with the correct letter box or pillar box settings, visible under the Image Size and Image Position items on the Picture Controls submenu. If you want a single input to fill the screen in follow mode, you can manually set the Image Position item on the Picture Controls submenu to 0,0 and set the Image Size to match the current output rate X, Y.

- Auto Memory — Select this item to enable or disable Auto Memory. When Auto Memory is enabled, the DSC stores the current input configuration and picture control values as a memory preset. All values are stored except preset name, film detect, and audio gain or attenuation (see Auto Memories on page 28 for more information).

- Overscan — Select this item to select a default overscan mode to apply to SMPTE input rates (480i, 576i, 720p, 1080i, 1080p, and 2K). This zooms and crops SMPTE inputs to mask edge effects and ancillary data that may occur in broadcast signals. The selections are .0% (the default), 2.5% , and 5.0% .

NOTE: If the overscan mode is not 2.5% or 5%, when Auto-Image is performed on an SMPTE input rate, it refers to the default input values for sizing and centering instead of performing a true Auto-Image.

- Factory Reset — Select this item to reset the unit to its factory-installed values (removing any user-defined values) while retaining the current firmware version. To reset using the OSD menu, press and hold the Enter button until Factory Reset is displayed. The message remains for approximately 1 minute after the reset is complete to allow time for the display device to sync with the DSC output.

NOTE: The equivalent SIS command is zxxx .

For other reset methods, see Resetting on page 30.

Communication Screen

This read-only screen (see figure 21) enables you to view the RS-232 remote port baud rate (left) and port type (right). The protocol for this port is 9600 baud, eight data bits, no stop bits, and no parity. You cannot change any of these port parameters.

Figure 21. Communication Screen

Device Info Screen

This read-only screen (see figure 22) provides a quick view of certain selections, parameters, and status information for the DSC. (All these items are also on other DSC screens. However, the Device Info screen provides them all on a single screen for a system overview).

Figure 22. Device Info Screen

Auto-Image

Auto-Image attempts to size and position the image to fill the display screen (fill mode) or uses the native aspect ratio of the input (follow mode). Only the horizontal and vertical positioning and size are adjusted by Auto-Image. All other controls are left unchanged.

• If the aspect ratio has been set to Fill, the H and V position returns to , , and the H Size and V Size are set to match the current output rate.
• If the aspect ratio has been set to Follow, the H and V position and size are set to maintain the native aspect ratio of the input rate to the current output resolution.

Auto-Image is useful in applications that involve a variety of new input sources (such as when a matrix switcher is connected). It is also useful for centering and sizing an image that has been adjusted out of default settings. To perform a one-time Auto-Image:

• Front panel: While the OSD is not displayed, press the Auto-Image (▶) button twice. The first press displays the message Press Auto to Confirm on the OSD. The second press initiates the Auto-Image.
• OSD submenus: Select Auto-Image / Press Enter to Auto-Image from either the Quick Setup submenu (see page 15) or the Input submenu (see page 19).
  • SIS commands (see the Auto-Image commands on page 37).
  • PCS configuration software (see the program help file).

Resetting the Output Resolution and Refresh Rate

If an output image cannot be displayed due to an incompatible output rate, you can use the front panel buttons to toggle the output rate between 720p @ 59.94 Hz and 1080i @ 59.94 Hz.

To set the rate or toggle between the two available rates:

1. Ensure that the OSD is closed by pressing and holding the Menu button for 3 seconds.
2. Press and hold the ▼ button until a message appears on the display indicating the new rate (approximately 5 seconds).

NOTE: On the front panel, the ▼ button is labeled Hold ▼ for 720p / 1080i.

Power Save Mode

In power save (standby) mode, all non-essential hardware is shut down in order to conserve power.

• To enable power save mode, enter the Power Save ON SIS command (see the Power Save Mode commands on page 42).
• To exit power save mode, either enter the Power Save OFF SIS command or press any front panel button (if the front panel is locked, this method does not work).

NOTE: The backup and restore functions available through the PCS control software are not accessible while the unit is in power save mode.

Presets

A preset is a set of input parameters that are saved either by you or automatically by the DSC as a file in DSC memory. Saved presets can be recalled and their settings implemented at any time. A preset saves time by enabling you to apply a group of settings to the DSC at one time.

The DSCs have three types of presets: Auto Memories, user presets, and global input presets.

Auto Memories

The DSC has 32 memory locations in which the current input configuration and picture control values are automatically stored as a preset when Auto Memory is enabled. An Auto Memory preset is recalled when an identical input resolution and rate is applied to the input. Each Auto Memory is stored with a time stamp that is incremented each time its stored rate is detected. If all Auto Memory slots are occupied and a new rate is applied, the Auto Memory with the oldest time stamp is overwritten.

Auto memory can be enabled using the OSD (see the Auto Memory item on the Advanced submenu on page 25) and by SIS commands (see the Auto Memories commands on page 40).

The following information is stored in an Auto Memory:

• Contrast • Horizontal image position
• Brightness • Vertical image position
  • Detail • Horizontal image size (width)
  • Total pixels • Vertical image size (height)

User Presets

Three memory slots are available for you to store certain input settings as a preset. You can then recall a saved preset and apply it to the current input.

NOTE: A user preset can be saved at one input resolution, then recalled at another.

User presets can be saved, recalled, and cleared via the OSD (see the User Presets submenu on page 16) or SIS commands (see the User Presets commands on page 41). The following values are saved in a user preset:

• Contrast • Horizontal image position
• Brightness • Vertical image position
  • Detail • Horizontal image size (width)
• Preset name • Vertical image size (height)

NOTE: You can change the picture and image settings using the Picture Controls submenu (see page 18) and Input submenu (see page 19) or SIS commands (see the Presets commands on page 40. The preset name can be assigned only via SIS commands.

Input Presets

The DSC has 128 memory slots in which you can save input presets. These presets allow a matrix switcher with multiple types of video inputs (such as an SMX) to be placed upstream from the DSC to expand the number of video sources. Input presets can be saved and recalled only through SIS commands (see the Input Presets commands on page 41).

Values for the following settings are saved in input presets:

• Film detect • Horizontal image position
• Contrast • Vertical image position
• Brightness • Horizontal image size (width)
  • Detail • Vertical image size (height)
  • Total pixels • Preset name
  • Audio gain and attenuation

Saving a preset when using a matrix switcher

When using the DSC with a matrix switcher, do the following to save a preset:

1. Switch each input of the matrix to the DSC.
2. Configure each input: size, position, detail, brightness, and contrast. (The total pixels are not user-configurable, but are stored automatically as part of the preset.)
3. Save the settings to a preset for recall by the control system when that matrix input is routed to the SDI input.

Locking the Front Panel (Executive Mode)

To prevent access by unauthorized users or accidental changes to settings, lock the front panel controls as follows. In this mode, all front panel buttons are disabled and configuration is available only by SIS commands and the PCS configuration software (see the program help file).

To lock the front panel, do either of the following:

• Press and hold the front panel Menu and ▼ buttons until the OSD displays the message Executive Mode Enabled (approximately 5 seconds). The message remains on the OSD approximately 2 seconds. It also appears when a front panel button is pressed while the front panel is locked.
• Enter the Enable SIS command (see the Front Panel Lock (Executive Mode) commands on page 46).

To unlock the front panel, do either of the following:

• Press and hold the front panel Menu and ▼ buttons again until the OSD displays the message Executive Mode Disabled (approximately 5 seconds). The message remains on the OSD approximately 2 seconds.
• Enter the Disable SIS command (see the Front Panel Lock (Executive Mode) commands).

Resetting

Resetting the unit causes various settings to revert to the defaults that were set at the factory. Resets can be performed from the front panel buttons, the OSD menu, or SIS commands. The following resets are available:

• Factory defaults: This reset clears all user-specified settings but retains the latest firmware version. You can perform this reset by:
• Selecting Factory Reset from the Advanced submenu of the OSD (see the Factory Reset item on the Advanced submenu on page 25)
• Entering the SIS command to reset all device settings to factory default (see the Reset command on page 46)
• Selecting Reset Device from the DSC 3G-3G A tab menu in the PCS software (see the program help file)

When the reset is complete, the message Factory Reset is displayed on the OSD.

- Factory Firmware: This reset returns the unit to its factory default settings, including the original firmware with which it was shipped. All user settings are cleared. To perform this reset, press and hold the Enter button for 30 seconds while applying power to the unit. When the reset is completed, the message Factory Reset appears on the OSD.

NOTE: The firmware reset and factory reset messages are displayed for 1 minute after the reset to allow time for the display device to sync with the DSC output.

Remote Configuration and Control

This section describes the connections through which the DSC can be configured and controlled remotely via SIS commands and describes the commands that are available. It also provides the procedure for accessing the PCS software. Topics include:

• SIS Commands
  • PCS Configuration Program

The DSC can be configured and controlled via a host computer or other device (such as a control system) attached to the front panel USB port or the rear panel RS-232 connector. Control is made using SIS commands. Enter commands using an application such as the Extron DataViewer, available at www.extron.com (see the DataViewer Help file to use this program). The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control.

SIS Commands

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the DSC determines that a command is valid, it executes the command and sends a response to the host device. All responses from the scaler to the host end with a carriage return and a line feed (CR/LF = ←), indicating the end of the response character string (one or more characters).

Copyright Information

The DSC sends the following copyright message if power is cycled while the DSC is connected to the host. It displays on the computer screen only with an RS-232 connection.

(c) Copyright 20nn, Extron Electronics, DSC 3G-3G A, Vn.nn, 60-1453-01←20nn is the year, DSC 3G-3G A is the model name, and Vn.nn is the firmware version.)

DSC-initiated Messages

When a local event such as a front panel selection or adjustment takes place, the DSC scaler responds by sending a message to the host. No response is required from the host. An example of a scaler-initiated message is shown below.

Reconfig

The DSC sends this response when a change in the input frequency is detected.

Error Responses

When the DSC receives a valid command, it executes the command and sends a response to the host device. If the unit is unable to execute the command because the command contains invalid parameters, it returns an error response to the host.

E01 — Invalid input number
E06 — Invalid switch attempt in this mode
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid port number
E13 — Invalid parameter
E14 — Invalid command for this configuration
E17 — Invalid command for signal type
E22 — Busy

Using the Command and Response Table

The Command and Response Table for SIS Commands, beginning on page 37, lists the commands that the DSC scaler recognizes as valid, the responses that are returned to the host, a description of the command function or the results of executing the command, and some examples of the command syntax in ASCII.

NOTE: Unless otherwise stated, upper- and lowercase text can be used interchangeably in the commands.

NOTES:

- In verbose response mode, the device (the DSC) responds with more information than it usually would.

For example, the DSC can send out a notice of a change in some setting without receiving a query via your PC. That change could have been a result of an internal process, a selection made from the front panel, or a selection made from the OSD. This is an example of a verbose (wordy) relationship between the controller and a connected device. Verbose mode creates more network traffic than usual, which can slow down network performance.

- If tagged responses are enabled, all "view" commands return the command string plus the data, the same as in responses for setting a value. For example, for the command to view the current screen saver mode:

Command: Esc M SSAV ←

Response: SsavM x40 ← (verbose mode with tagged response) or

x40 ← (non-tagged response)

PCS Configuration Program

The Extron PCS control program is a Windows-based program that provides a convenient way to configure the input and output, audio, and image settings for the DSC 3G-3G A. It lets you perform nearly all the other functions that can be accomplished via the front panel controls or SIS commands.

Downloading the PCS Configuration Software from the Website

To use the Product Configuration Software, download the program from www.extron.com and install it on the PC that will be connected to the DSC, as described in the following sections. You can also download updates to the DSC software as they become available. To access the software:

1. Open the Extron web page and select the Download tab (see figure 24, ①).
2. On the Download screen, click the PCS link on the left sidebar menu (see figure 24, ②).

Figure 24. PCS Software Link on the Download Page of the Extron Website

1. On the PCS page, click the Download Now button in the Key Features added in the Current Release panel (see figure 25, 1).

Figure 25. Download Now Button on the PCS Web Page

1. On the Download Center page that is displayed next, fill in the required information, then click the Download pcss_vnxn.exe button.

2. If the File Download - Security Warning window appears, click Run to begin downloading the installer file.

NOTE: If you want to save the installation file to your computer hard drive to run later, click Save. On the Save As window that opens, save the setup file to the desired location. When you are ready to install the software, double-click on the pcss_vnxnxn.exe icon, click Run on the Download screen that opens, and restart this procedure at step 7.

If, instead, you see a Download icon at the bottom of the page, wait until the icon displays the name pcss_vnxnxn.exe, then click it.

1. On the next prompt window that opens, click Run to start the installation process.

2. Follow the instructions on the InstallShield Wizard screens to complete the software program installation. By default the installation creates a folder called "Extron PCS" in one of the following location on the computer (depending on Windows version):

c:\Program Files (x86)\Extron\Extron PCS or c:\Program Files\Extron\Extron PCS

If there is not already an Extron folder in your Program Files or Program Files x86 folder, the installation program creates it as well.

Starting the Configuration Program

In order to use the PCS software, the DSC must be connected to your computer via the front panel USB port (see Connecting for Remote Control on page 7).

1. To start the PCS configuration program, do either of the following:

- Double-click on the EAF.exe file, located on your computer at c:\Program Files [or Program Files(x86)]\Extron\Extron PCS.

- Access the program from the Start menu on your computer as follows:

a. Click Start on your computer screen.

b. Select All Programs from the Start menu.

c. From the All Programs menu, select Extron Electronics/Extron Product Configuration Software/Extron Product Configuration Software. The Extron Product Configuration Software window opens.

1. The first time you open the PCS software, the Tutorial screen appears. To close this screen, click I Get It.

2. On the Extron PCS window, click on DSC 3G-3G A (see figure 26, ①) in the Device Discovery panel. The Connect button in the bottom-right corner becomes available.

3. Click Connect (see figure 26, ②) to open the DSC 3G-3G A main window.

Updating Firmware

Extron periodically updates product firmware in conjunction with the release of new software revisions. Before updating any Extron product to the latest revision level, be sure to read the supplied release notes or contact Extron Technical Support to determine if your product requires a firmware update.

You can update firmware using the PCS configuration software. See the program help file for the procedure.

Mounting

The DSC 3G-3G A scaler can be mounted by any of the following methods (see www.extron.com for available Extron mounting kits and ordering information):

- Rack mounting: Attach the DSC to a standard 19-inch rack shelf.

The following Underwriters Laboratories (UL) guidelines pertain to the installation of the DSC 3G-3G A in a rack:

- Elevated operating ambient temperature — If the equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (TMA) specified by the manufacturer.

- Reduced air flow — Install the equipment in the rack so that the amount of air flow required for safe operation of the equipment is not compromised.

- Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not create a hazardous condition.

- Circuit overloading — When connecting the equipment to the supply circuit, consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings when addressing this concern.

- Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).

• Under-furniture mounting: Mount the DSC under the surface of a desk, table, or podium.
• Through-furniture mounting: Mount the DSC through a table or desk in which a hole has been cut to enable access to the front panel.
• Free-standing: Attach the four rubber feet to the bottom of the DSC in the four corners and place the unit on furniture as desired.

To mount the DSC 3G-3G A using an Extron mounting kit, see the instructions provided with the kit.
