Wiring the Audio Input Connector  
ATTENTION:  
The length of the exposed wires in the stripping process is critical. The ideal  
length is 3/16 inch (5 mm). If the exposed portion is longer, the wires may  
touch, causing a short circuit between them. If the exposed wires are shorter,  
they can be easily pulled out, even if tightly fastened by the captive screws.  
Do not tin the wires. Tinned wire does not hold its shape and can become  
loose over time.  
For unbalanced audio, connect the sleeves to the ground contact. Do not  
connect them to negative (–) contacts.

Input AFL — This option lets you turn the Extron Accu-RATE Frame Lock (AFL) on  
and off. The default is Off.  
When enabled, this mode locks the output vertical refresh rate to the vertical refresh  
rate of the currently selected input using Accu-RATE Frame Lock technology. This  
ensures no frames of the input are repeated or dropped due to frame rate conversion.  
Input AFL mode can cause glitches or interruptions in the output sync when a new  
input is selected, or when a new signal has been routed to the selected input, as the  
DSC locks to the new vertical refresh rate.  
NOTE: AFL locks the output refresh rate to similar input rates. If the input signal  
is locked on a rate that is not considered a standard HDMI 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.  
If no input signal is detected (AFL disabled), or if locking to the input signal is not  
possible, a free running pixel clock is generated by the DSC.  
Output Submenu — DSC HD-3G A  
This submenu allows you to configure the output of the DSC HD-3G A.  
NOTE: The DSC HD-3G A has some different options on this submenu from  
DSC 3G-HD A (see Output Submenu — DSC 3G-HD A on page 25).

Genlock/AFL — This option lets you 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. This selection is the 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 — This option lets you adjust the horizontal and vertical offset  
of the genlock signal. (This feature can be adjusted only if the DSC is set up for SDI  
genlock.)  
Use the or button to adjust the horizontal (H) offset value. Use the  
button to adjust the vertical (V) offset value.

Screen Saver and Timeout — This option lets you enable screen saver mode,  
in which the video output is muted to black or blue if there is no active input video  
signal. It also lets you 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 t or button. The options are Black  
(default) or Blue.  
To set the sync timeout, press the  
1 through 500 seconds before the output sync times out. The default is Never,  
or button. You can select a duration of  
meaning that the sync does not time out.  
NOTE: The DSC exits screen saver mode when a front panel 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 40), front panel button presses  
have no effect on screen saver mode.  
Aspect Ratio — This option lets you 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  
Controlssubmenu (ImageSizeand Position) (see Picture Controls  
submenu on page 22).  
In follow mode, each input rate is displayed with its native aspect ratio (4:3,  
5:4, 15:9, 16:9, 16:10) with the correct letter box or pillar box settings, visible  
under the ImageSizeand ImagePositionoptions on the PictureControls  
submenu.  
If you want a single input to fill the screen in follow mode, you can manually set  
the ImagePositionoption on the PictureControlssubmenu to 0,0and set  
the ImageSizeto match the current output rate X, Y.  
Auto Memory — This option lets you enable or disable Auto Memory. When Auto  
Memory is enabled, the DSC stores the current input configuration and picture control  
values as an input preset. All values are stored except preset name, film mode, and  
audio gain or attenuation (see Auto Memories on page 38 for more information).  
Overscan — This option lets you select a default overscan mode to apply to SMPTE  
input rates (480i, 576i, 480p, 576p, 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 options are 0%(the default), 2.5%, and 5%.  
NOTE: If the overscan mode is not 0%, 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.  
Temperature — This read-only field shows the internal temperature of the unit in  
Fahrenheit (left value) and Celsius (right value).  
Factory Reset — This option lets you reset the unit to its factory-installed values  
(removing any user-defined values) while retaining the current firmware version.  
To reset using the OSD, press and hold the Enter button until FactoryReset  
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. (The  
equivalent SIS command is <ESC> zxxx<CR>.) For other reset methods, see  
Resetting on page 40.

Auto-Image  
When Auto-Image is performed, the DSC attempts to size and position the image to fill  
the display screen (fill mode) or use the native aspect ratio of the input (follow mode).  
Using SIS commands or the OSD submenus, you can perform a one-time Auto-Image on  
the current input.  
Only the horizontal and vertical positioning and the horizontal and vertical size are  
adjusted by the Auto-Image. All other controls are left unchanged.  
If the aspect ratio has been set to Fill, the H and V position returns to 0,0, and the H  
and V Size is 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 with respect to the current output  
resolution.  
Auto-Image is useful in applications in which a variety of new input sources may be  
encountered (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.  
You can perform a one-time Auto-Image by the following methods:  
Front panel: While the OSD is not displayed, press the Auto-Image () button twice.  
(The first press displays the message PressAutoto Confirmon the OSD. The  
second press initiates the Auto-Image.)  
OSD submenus: Select the Auto-Image/ PressEntertoAuto-Imageoption from  
the Quick Setup submenu (see page 18) or the Input submenu (see page 23).  
SIS commands (see the Auto-Image commands on page 49).

Changing the Output Resolution and Refresh Rate  
In addition to the Output submenus (see pages 25 and 27), other options for setting  
the output resolution and refresh rate include resetting the output rate using the front  
panel button (see Resetting the Output Rate on page 37), SIS commands (see the  
Output Configuration commands beginning on page 54, and the Windows-based  
Control Program (see the program help file).  
Custom Rates — DSC 3G-HD A Only  
In addition to the 42 factory output resolutions, 3 custom user-defined rates are available  
for the DSC 3G-HD A via SIS commands (see the Output Scaler Rate SIS commands  
on page 54 for the command format) or the Windows-based Control Program (see the  
program help file). When no custom EDIDs are defined, these three resolutions and rates  
default to 720p @ 60 Hz. The OSD dynamically updates itself based on the current file  
stored in the custom EDID slot. For example, if a custom 720p EDID has been uploaded,  
the OSD would read C1:720P@60Hz.  
Importing an HDMI EDID — DSC 3G-HD A Only  
You can also import the EDID of a connected HDMI sink to use as a custom rate. This  
EDID can be saved and stored in one of three custom EDID slots, which are then available  
for custom EDID emulation or custom output rate generation (custom rate based on the  
EDIDs preferred timings) (see the Output EDID command on page 54).  
NOTE: If an imported or custom rate is not a valid output resolution, the output  
reverts to the default (720p @ 60 Hz).  
Changing the Output Resolution from the Front Panel — DSC HD-3G A Only  
Depending on which Output LED is lit (2.97 Gbps for 3G-SDI, 1.485 Gbps for HD-SDI,  
or 270 Mbps for SD-SDI) you can press a combination of front panel buttons to cycle  
through the different levels of output signal format and change the resolution. This is  
helpful if you are not able to display an image on the screen.  
To change the resolution using the front panel buttons:  
1. With the scaler powered on, press and hold the Menu and Auto-Image () buttons  
until the 1.485 Gbps (HD-SDI) LED lights approximately 5 seconds), indicating that  
the unit is now outputting 720p @ 59.94 Hz. If a screen is connected, the following  
message is displayed:  
PressEntertoconfirmthenewresolution.Unitwillreturntoprevious  
resolutionin15secondsifnotconfirmed.  
2. Press the  
or button repeatedly to cycle through the output resolutions typically  
associated with the HD-SDI output format.  
NOTE: If you do not press a button within 15 seconds, the DSC reverts to the  
previous output rate and you must return to step 1 if you want to select another  
resolution.

Presets  
A preset is a set of input parameters that are either saved by you or automatically by  
the DSC as a files 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 an input 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 preset 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 option of the  
Advancedsubmenu on page 33) and by SIS commands (see the Auto Memories  
commands on page 53).  
The following information is stored in an Auto Memory preset:  
Contrast  
Active lines (V Active)  
Horizontal image position  
Vertical image position  
Horizontal image size (width)  
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 User Presets  
submenu on page 19) or SIS commands (see the User Presets commands on  
page 53). The following values are saved in a user preset:  
Contrast

NOTE: You can change the picture and image settings using the Picture Controls  
submenu (see page 22) and Input submenu (see page 23) or SIS commands (see  
the Presets commands on page 53. The preset name can be assigned only via SIS  
commands.  
Input Presets  
The DSC has 16 memory slots in which you can save input presets that are global to the  
HDMI or SDI input. 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 54).  
Values for the following settings are saved in input presets:  
Contrast  
Active pixels (H Active)  
Active lines (V Active)  
Horizontal image position  
Vertical image position  
Horizontal image size (width)  
Vertical image size (height)  
Total pixels  
Brightness  
Detail  
Film Mode  
Audio gain and attenuation  
Horizontal start  
Vertical start  
Preset name  
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 remaining  
settings — H start, V start, active pixels and lines, and 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 HDMI or SDI input.

Locking the Front Panel (Executive Mode)  
To prevent access by unauthorized users or accidental changes to the DSC settings, you  
can lock the front panel controls by placing the DSC in executive mode. In this mode, all  
front panel buttons are disabled and control is available only by SIS commands.  
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.  
Enter the EnableSIS command (see the Front Panel Lock (Executive Mode)  
commands on page 59).  
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 ExecutiveModeDisabled(approximately 5 seconds). The message  
remains on the OSD approximately 2 seconds.  
Enter the DisableSIS command (see the Front Panel Lock (Executive Mode)  
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, 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 FactoryResetfrom the Advancedsubmenu of the OSD (see the  
Factory Reset option of the Advancedsubmenu on page 33)  
Entering the ResetalldevicesettingstofactorydefaultSIS command  
(see the Reset command on page 60)  
When the reset is complete, the message FactoryResetis 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 20 seconds while applying  
power to the unit. When the reset is completed, the message FirmwareReset  
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.  
Topics include:  
The DSC can be configured and controlled via a host computer or other device (such as a  
control system) attached to the rear panel RS-232 connector or the front panel USB port.  
Control is made using the Extron Simple Instruction Set (SIS) of commands.  
Commands can be entered using a Telnet application such as the Extron DataViewer,  
available at www.extron.com. See the DataViewer Help file for use.  
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 upon connection to the host (it displays  
on your computer screen only with an RS-232 connection):  
](c)Copyright20nn,ExtronElectronics,DSCXX-XXA,Vn.nn,60-130n-01]  
(20nnis the year, DSC XX-XXA is the model name, Vn.nnis the firmware version number,  
and 60-130n-01 is the unit part number.)

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. Example scaler-initiated messages are listed here.  
Reconfig]  
The DSC sends this response when a change in the input frequency is detected.  
HplgO]  
The DSC 3G-HD A sends this response when a hot plug event on the output is  
detected (for example, when the unit is unplugged and reconnected).  
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 49, 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 an example of each command in ASCII.  
NOTE: Unless otherwise stated, upper- and lowercase text can be used interchangeably in the  
commands.

Windows-based Control Program  
The Extron Product Configuration Software (PSC) is a Windows-based program for the  
DSC that provides a convenient way to configure the input and output, audio, and image  
settings. It also lets you save and recall presets and perform nearly all the other functions  
that can be accomplished via the front panel controls or SIS commands. The Product  
Configuration Software is provided on a disk that is delivered with your DSC unit and can  
also be downloaded from www.extron.com. To use the software, you must install the  
program on your PC as described in the following sections.

Reference  
Information  
This section contains information on mounting the DSC scaler. See www.extron.com for  
available Extron mounting kits and ordering information.  
Mounting Options  
The DSC 3G-HD A and DSC HD-3G A scalers can be mounted by any of the following  
methods:  
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-HD and HD-3G 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 using an Extron mounting kit, see the instructions provided with the kit.
