Figure 3. Wiring the Audio Output Connector
ATTENTION:
• For unbalanced audio, connect the sleeves to the ground contact. Do not
connect them to negative (–) contacts.
• Pour l’audio asymétrique, connectez les manchons au contact au sol. Ne
PAS connecter les manchons aux contacts négatifs (–).
• 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.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend
de les dénuder. S’ils sont un peu plus longs, les câbles exposés pourraient
se toucher et provoquer un court circuit. S’ils sont un peu plus courts, ils
pourraient sortir, même s’ils sont attachés par les vis captives.
• Do not tin the wires. Tinned wire does not hold its shape and can become
loose over time.
• Ne pas étamer les câbles. Les câbles étamés ne sont pas aussi bien fixés
dans les terminaisons des connecteurs à vis captives et pourraient sortir.

• HDCP Authorized — Select this item to enable or disable HDCP communication by
selecting whether the DSC input will report to the source as an authorized HDCP sink.
After selecting the item, press any arrow button to toggle between On (the default)
and Off.
Setting HDCP authorization to Off is useful for devices that always encrypt their
output if the downstream sink is capable of HDCP. If HDCP signals are not allowed
on an input, most content from these sources can be passed as a non-encrypted
signal to the digital video output. In a video system that should not transmit HDCP
encrypted data, such as broadcast or streaming environments, HDCP authorization
should be disabled at the input to keep the scaler output unencrypted.
When input HDCP authorization is disabled, the DSC does not display content that
requires HDCP from the HDMI output and the DP loop output. Instead, the output
displays either a black screen or a warning message.
• Input EDID — Select this item to select an EDID (resolution and refresh rate)
emulation for the DisplayPort input. You can match the input EDID to the output
rate or set a discrete EDID. The DSC can also capture the EDID from the sink
attached to the DP loop-through or from the HDMI output and present that EDID
to the source connected to the input. The EDID table on the next page shows
the available EDID selections, including their SIS command variable numbers (see
Remote Configuration and Control, beginning on page 35, for information on SIS
commands).

• Output Resolution — Select this item to specify the resolution and refresh rate for
the connected output display. The DSC DP-HD A has a range of resolutions from
which to choose (see the Output Resolutions and Refresh Rates table on the next
page for the available settings). The available refresh rates depend on the selected
resolution.
Three custom user-defined output rates are also available to be defined via SIS
commands. If no rates are defined for any of these three slots, they default to
720p @ 60 Hz. When a resolution is applied to a user-defined command slot, its
name is displayed in the Output Resolution space in the format cn: nnnnxnnnn @ nn
(for example, C1: 1280x780 @ 60).
To select an output resolution, select Output Resolution from the Output
submenu. When you enter a new resolution, a message appears on the display,
prompting you to press Enter to confirm your selection. Press the Enter button to

• HDCP Notification — Select this item to select what is displayed on the
HDMI output screen and the loop-through monitor if the input signal contains
HDCP-protected content but the output is a non-HDCP sink. Select this item, then
press Enter. Press any arrow button to toggle between:
• On — Displays a green screen with the message HDCP Content on the HDMI
output display. On the monitor connected to the DisplayPort loop connector, it
displays a green screen with no message.
• Off — Displays a black screen and the output sync is maintained.
NOTE: Displaying the green screen is possible only when HDCP Authorized is
enabled (see the HDCP Authorized item on page 21).
• Input AFL — Select this item to 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.

• 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.
DSC DP-HD A • Operation 30
Page 37
You can perform a one-time Auto-Image by the following methods:
• Front panel button: 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 the Auto-Image / Press Enter to Auto-Image item from
the Quick Setup submenu (see page 16) or the Input submenu (see page 20).
• SIS commands (see the Auto-Image commands on page 42).
• PCS software (see the program help file).
Changing the Output Resolution and Refresh Rate
In addition to the Output submenu (see page 23), other items for setting the output
resolution and refresh rate include resetting the output rate using the front panel button
(see Resetting the Output Rate), SIS commands (see the Output Configuration
commands beginning on page 47), and the PCS control program (see the program help
file).
Custom Rates
In addition to the 42 factory output resolutions, three custom user-defined rates are
available. Using SIS commands or the PCS control program, you can capture the EDID
of the device connected to the HDMI output or to the loop-through connector (see the
Output Scaler Rate SIS commands on page 47 or the control 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 display
C1: 720p @ 60 Hz.
Resetting the Output Rate
Power Save Mode
If an output image cannot be displayed due to an incompatible output rate, you
can use the front panel down arrow button to toggle the output rate between
1024x768 @ 60 Hz (XGA or 1080i) and 1280x720 (720p) @ 60 Hz. To set the rate or
toggle between the two available rates:
1. Ensure that the OSD is closed by pressing and holding Menu 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 XGA/720p.
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 48).
• 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
Auto Memories
A preset is a set of input parameters that are either saved 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.
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 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 memories can be enabled using the OSD (see the Auto Memory item on
the Advanced submenu on page 27), by SIS commands (see the Auto Memories
commands on page 46), and the PCS software (see the program help file).
The following information is stored in an Auto Memory preset:
• Contrast • Active lines (V Active)
• Brightness • Horizontal image position
• Detail • Vertical image position
• Horizontal start • Horizontal image size (width)
• Vertical start • Vertical image size (height)
• Active pixels (H Active) • Total pixels
User Presets
Three memory slots are available for you to store input settings as a preset. You can then
recall a saved preset and apply it.
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 16) or SIS commands (see the User Presets commands beginning
on page 46). 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 19) and Input submenu (see page 20), SIS commands (see
the Presets commands on page 46, or the PCS software (see the program help
file). The preset name can be assigned only via SIS commands.
DSC DP-HD A • Operation 32
Page 39
Input Presets
The DSC has 128 memory slots in which you can save input presets that are global to
the HDMI input or DisplayPort loop through. 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 47).
Values for the following settings are saved in input presets:
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
3. Save the settings to a preset for recall by the control system when that matrix input is

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.
routed to the HDMI input or DisplayPort loop through.
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 any 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 Enable SIS command (see the Front Panel Lock (Executive Mode)
commands on page 51).
• Select Lock Front Panel from the PCS software (see the program help file).
To unlock the front panel, do any 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).
• Select Unlock Front Panel from the PCS software (see the program help file).

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 Factory Reset from the Advanced submenu of the OSD (see the
Factory Reset item on the Advanced submenu on page 29)
• Entering the SIS command to reset all device settings to factory default (see the
Reset command on page 52)
• Selecting Reset Device from the DSC DP-HD 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 Firmware 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 rear panel RS-232 connector or the front panel
USB port. Control is made using the Extron Simple Instruction Set (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
Copyright Information
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).
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.

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. Examples of scaler-initiated messages are listed below.
• Reconfig ]
The DSC sends this response when a change in the input frequency is detected.
• HplgO ]
The DSC sends this response when a hot plug event on the output is detected (for
example, when the unit is unplugged and reconnected).

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:
Command: E M SSAV }
Response: SsavM X1! ] (verbose mode)
or X1! ] (non-verbose mode)
