DSC HD-3G A Scaler • Setup Guide
The Extron DSC HD-3G A is an HDMI to 3G-SDI scaler that converts HDMI signals to 3G-SDI, HD-SDI, and SD-SDI. It accepts
computer and SMPTE video resolutions up to 1920x1200 and 2k, and offers multiple output rates from 480i up to HDTV
1080p @ 60 Hz and 2k. The DSC HD-3G A features advanced Extron video signal processing with 1080i deinterlacing and Deep
Color processing for optimal image quality. Dual SDI outputs, stereo audio embedding, and genlock are also provided.
This setup guide provides step-by-step instructions for an experienced user to set up and configure a DSC HD-3G A. It covers
how to perform basic operations using the front panel controls and selected Simple Instruction Set (SIS™) commands.
NOTE: For full installation, configuration, menus, connector wiring, and operation details, see the DSC 3G-HD A and

Mounting and Cabling the DSC HD-3G A
1. Disconnect power: Turn off or disconnect all equipment power sources.
2. Mount the unit: (Optional) Mount the DSC HD-3G A either in a rack using
shelf mounting brackets (RSU 129 or RSB 129) or under furniture using
furniture mounting brackets (MBU 125) (see gures 1 and 2 at right). A false
face plate (RFF 052) can be tted on top of the low prole DSC if desired.
3. Connect the input: Connect an HDMI video source to the HDMI input
connector c.
4. Connect analog audio input: (Optional) Connect analog audio from the
source to the captive screw Audio input connector b.
NOTE: To embed audio from this input, you must first set it up using
the on-screen display (OSD) (see page 2) or SIS commands (see
page 4).
5. Connect the output: Connect one or two SDI display devices to
the 3G/HD/SD-SDI output connectors efor SDI output with optional
embedded analog or HDMI audio.
6. Connect a control device: For remote control via SIS commands or
the PCS Windows®-based control software:
zRS-232 — For serial RS-232 control, connect a host computer or
control system to the 3-pole captive screw RS-232 connector f.
RS-232 protocol (default values) are 9600 baud, 1 stop bit, no
parity, 8 data bits, no ow control.
zUSB — Connect a host computer or control system to the front
panel mini USB port (bin the front panel illustration on page 2)
for conguration and control via Extron PCS Control software.
7. AC power connector — Connect the supplied US standard IEC
power cord between this connector aand a 110-220 V 50-60 Hz AC
power source.

eMenu and Enter buttons — Let you access the OSD and select submenus and options from the menus.
fNavigation buttons — Press these right , left , up , and down arrow buttons to step through the OSD submenus,
to lock the front panel (see the next section), perform Auto-Image (press ), and reset the output rate (hold for 5 seconds).
Locking the Front Panel (Executive Mode)
To prevent unauthorized access or accidental changes to DSC settings, you can lock the front panel controls, making control
available only by SIS commands. (The default state is unlocked.) You can lock and unlock the front panel as follows:
zUsing the front panel buttons: To lock, press the Menu and buttons simultaneously and hold them until the OSD
displays Executive Mode Enabled (approximately 5 seconds). To unlock, repeat this process.
zSIS commands: To lock (enable executive mode), enter 1X. To unlock (disable executive mode), enter 0X.
Configuring the DSC HD-3G A
The DSC HD-3G A can be configured through a host connected to
the RS-232 or USB port, using Extron PCS Windows-based control
software (available at no charge at www.extron.com) or SIS
commands (see page 4 for a selection of basic commands). You
can also configure it using the OSD menu system, described below.
On-Screen Display (OSD) Menu System
The OSD menu system consists of seven submenus and two
information screens. To access the menus, press the front panel
Menu button. With the main menu displayed, use the arrow buttons
to step through the submenus and submenu options. Press the
Enter button to select items that you highlight. Communication and
Device Info screens are read-only and do not provide selections.
•Quick Setup •User Presets •Picture Controls
•Input •Output •Audio
•Advanced •Communication •Device Info.
NOTE: The OSD times out and closes after 1 minute if no
buttons are pressed.

To use any menu:
1. Press the Menu button to access the main menu. The menu opens with the Quick Setup menu displayed.
2. Press the and buttons repeatedly to cycle through to the desired submenu (each button press outlines the next option).
3. Press the Enter button to access the desired submenu. The rst option is outlined in yellow.

Setting Up the DSC HD-3G A Using the OSD Menu
The Quick Setup submenu is displayed when the OSD opens. This submenu contains options from other submenus that you are
most likely to need when configuring the DSC for the first time. Use the Quick Setup submenu to perform a basic system setup
and get started quickly using the DSC. Select the following options from it as needed:
zAuto-Image™ — Performs an Auto-Image on the video input to adjust the horizontal and vertical size and positioning to
the selected aspect ratio (ll the screen or follow the input device aspect ratio). To perform an Auto-Image, select this option,
then press Enter again to initiate the Auto-Image.
zInput EDID — Matches the input EDID to the output rate or sets a discrete EDID. After selecting Input EDID, press the or
button to step through the available EDIDs (the default is 720p @ 59.94 Hz).
zOutput Resolution — Lets you select the resolution and refresh rate for the current output from 42 available
factory-installed rates (see "Output Scaler Rates"). Select the Output Resolution submenu, then press the and 
buttons to cycle through the available rates.
zAuto Memory — Sets the DSC to automatically save the current input conguration and picture control values according
to the most recent conguration for each different rate. After selecting Auto Memory, press any arrow button to toggle Auto
Memories on and off.
zAspect Ratio — Lets you specify how much of the display the image lls. The sub-options are Fill (lls the entire screen)
or Follow (uses the aspect ratio of the input). After selecting Aspect Ratio, press any arrow button to toggle between
Fill and Follow.
zInput Audio Format — Lets you select the format of the audio to embed in the output. After selecting Input Audio
Format, press any arrow button to cycle through the options: None (mute the audio), Analog (embed analog audio onto the
SDI output), LPCM-2CH (use the rst channel pair), Multi-Ch (use the rst four channel pairs).
zTest Pattern — Lets you select from seven test patterns to aid in setting up the DSC and the output display.
Output Scaler Rates
Output rates can be set using the OSD menu or SIS commands. The table below gives the rates and their SIS variables (see
page 4 for the commands).
