The Extron DSC 3G-3G A scaler converts between 3G-SDI, HD-SDI, and SD-SDI resolutions and frame rates. It accepts, scales,
and outputs SMPTE video resolutions from 480i and 576i up to 1080p/60 and 2K. Stereo audio embedding and de-embedding,
dual SDI outputs, genlock, and an SDI input loop-through are also provided. Configuration and control are available via the
Windows®-based PCS configuration software, Simple Instruction Set (SIS™) commands, and the on-screen display (OSD) menus.
This setup guide provides step-by-step instructions for an experienced user to set up and configure a DSC 3G-3G A.
NOTE: For full installation, configuration, menus, connector wiring, and operation details, see the DSC 3G-3G A User Guide,
available at www.extron.com.

Mounting and Cabling the DSC 3G-3G A
1. Disconnect power — Turn off or disconnect all equipment power sources.
2. Mount the unit — (Optional) Mount the DSC 3G-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 the instructions provided with the mounting kit).
3. Connect the input — Connect an SDI video source to the 3G/HD/SD-SDI BNC input connector (
4. Connect a monitor — (Optional) Connect a local monitor to the SDI loop-through BNC connector (
reclocked copy of the input.
5. Connect analog audio input — (Optional) Connect analog audio from the source to the captive screw Audio input
connector (G) for balanced or unbalanced input.

8. Connect a computer or control device — For remote conguration and control via the PCS software or SIS commands:
z RS-232 — For serial RS-232 control, connect a host computer or control system to the 3-pole captive screw RS-232
connector (see figure 1, I, on the previous page). RS-232 protocol (default values) are 9600 baud, 1 stop bit, no parity,
8 data bits, no ow control.
z USB — For conguration via the Extron PCS Conguration software, connect a host computer to the front panel USB
mini-B port (see figure 2, B) .
9. Connect power to the unit — Connect the supplied US standard IEC power cord between the power connector (see
figure 1, A, and 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
configuration available only by SIS commands or the PCS
configuration software. (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 3G-3G A
The DSC 3G-3G A can be configured through a host connected
to the RS-232 or USB port, using the 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
on page 3. The illustration at right shows the Quick Setup menu,
which is the opening OSD screen.
