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.

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.

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.

Changing the Output Resolution and Refresh Rate
the output resolution and refresh rate include resetting the output rate using the front
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
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

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.

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,
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,

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

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.
