ore connecting the
wer source.
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, menu, connector wiring, and operation details, see the DSC 3G-HD A and
DSC HD-3G A User Guide, available at www.extron.com.

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
half-rack faceplate can be tted next to the 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, 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 E for SDI output with optional embedded
analog or HDMI audio.
6. Connect a sync device — (Optional) Attach an external sync device
to the input (right) Sync connector (D). Connect any downstream
device to be synchronized by genlocking to the output (left) Sync
connector (D).
7. Connect a control device — For remote control via SIS commands
or the PCS Windows®-based control software:
z RS-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.
z USB — Connect a host computer or control system to the front
panel mini USB port (B in the front panel illustration on page 2)
for conguration and control via Extron PCS software.
8. AC power connector — Connect the supplied US IEC power cord
to this connector A from a 110-220 V, 50-60 Hz AC, power source.

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:
z Using 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.
z SIS 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 configuration 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 items.
Press the Enter button to select the item that you highlight. The

Setting Up the DSC HD-3G A Using the OSD Menu
The Quick Setup submenu is displayed when the OSD opens. Use this submenu to perform a basic system setup and get
started quickly using the DSC. Select the following items from it as needed:
z Auto-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 item, then
press Enter again to initiate the Auto-Image.
z Input EDID — Matches the input EDID (extended display identication data) to the output rate or sets a discrete EDID. After
selecting Input EDID, press the or button to view the available EDIDs (the default is to match the DSC output rate).
z Output 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.
z Auto Memory — Sets the DSC to automatically save the current input conguration and picture control values according
to the most recent conguration for each different rate. After selecting Auto Memory, press any arrow button to toggle Auto
Memories on and off.
z Aspect Ratio — Lets you specify how much of the display the image lls. The submenu items 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.
z Input 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 items: 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).
z Test Pattern — Lets you select from seven test patterns to aid in setting up the DSC and the output display.
