DSC 3G-HD A Scaler • Setup Guide
The Extron DSC 3G-HD A is a 3G-SDI to HDMI scaler that converts 3G-SDI, HD-SDI, and SD-SDI signals to HDMI. It accepts
and scales SMPTE video resolutions from 480i and 576i up to 1080p @ 60 Hz and 2K, and offers multiple output rates up to
1920x1200, including HDTV 1080p/60 and 2K. Stereo audio embedding and an SDI input loop-through are also provided.
This setup guide provides step-by-step instructions for an experienced user to set up and configure a DSC 3G-HD 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
DSC HD-3G A User Guide, available at www.extron.com.

Mounting and Cabling the DSC 3G-HD A
1. Disconnect power: Turn off or disconnect all equipment power sources.
2. Mount the unit: (Optional) Mount the DSC 3G-HD 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 SDI video source to the 3G/HD/SD-SDI
BNC input connector B.
4. Connect a monitor: (Optional) Connect a local monitor to the buffered
Loop Thru SDI connector C.
5. Connect analog audio input: (Optional) Connect analog audio from the
source to the captive screw Audio input connector D.
NOTE: To embed analog 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).
6. Connect the output: Connect an HDMI display device to the HDMI
output connector Efor HDMI output (with optional analog audio if
connected and embedded).
7. Connect a control device: For remote control via SIS commands or
the Extron PCS Windows®-based control software:
zRS-232 — For serial RS-232 control, connect a host computer 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 to the front panel mini USB
port (Bin the front panel illustration on page 2) for conguration
via Extron PCS software.
8. 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. Figure 2. Under-furniture Mounting

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 submenu items are Fill (lls the entire
screen) and 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
items: None (mute the audio), Analog
(embed analog audio onto the HDMI
output), 2CH Digital (select one
channel pair), 8CH Digital (use rst
four pairs), and SDI Audio Decode
(select a pair from a group).
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 at
right gives the rates and their SIS variables
(see the SIS table on page 4).
Output Rate Reset
If an image cannot be displayed due to an
incompatible output rate, you can reset
the output rate as follows:
With the OSD closed, press and hold the
button for approximately 5 seconds to
toggle between 1024x768 @ 60 Hz and
720p @ 60 Hz.
