Mounting and Cabling
Step 1 — Mounting
Turn off or disconnect all equipment power sources and rack mount the
DSC 301 HD unit with either an optional shelf mounting brackets (RSU 126 or
129, RSB 126 or 129) or optional furniture mounting brackets (MBU 125); see
figures 1 and 2 at right. When rack mounting, an optional rack false face plate
(RFF 052) can be fitted on top of the low profile DSC, improving the overall look
within the rack.
Step 2 — Connecting inputs
Connect inputs from video sources to the applicable connectors marked “Inputs”:
bComposite video, cRGB, R-Y, Y, B-Y, dHDMI (with or without embedded
digital audio).
Connect inputs from analog audio sources to the TRS inputs e.
Step 3 — Connecting outputs
Connect a suitable output display device to the connector marked “Output”
(see fabove) for HDMI output with embedded audio.
Step 4 — Connecting control devices
RS-232 — For serial RS-232 control, connect a host computer or control
system to the 3-pole captive screw connector g.
RS-232 protocol (default values): 9600 baud, 1 stop bit, no parity, 8 data bits,
no flow control.
USB — Connect a host computer or control system to the front panel mini USB
port for configuration and control via Extron Configurator software.
Step 5 — Connecting power
DC power connector — Plug in a 12 VDC, 1A max power source into this
2-pole captive screw connector a.

DSC 301 HD Configuration Software
To configure the unit using the DSC 301 HD
Configuration software, the software must be
installed (from the included DVD or from
www.extron.com) on a PC connected to the
DSC 301 HD via an RS-232 or via the front panel
USB config port. Installation creates a
C:\Program Files\Extron\DSC 301 HD
folder and installs the program, a help file, and an
uninstall utility. After installation, start the program
and either connect via the comm (RS-232) port or
by USB. For full instructions press <F1> or click on
Help>Contents.
Upgrading the Firmware
The onboard firmware of the DSC 301 HD unit can
be upgraded via the configuration software when
connected via the front panel USB port.
Alternatively upgrades can be made using the Extron Firmware Loader program, which is available online at www.extron.com.

Output Rate Reset
If an output image cannot be displayed due to an incompatible output rate, the DSC 301 HD can be reset via the front panel to either
1024x768 @ 60 Hz or 720p @ 60 Hz.
To set the rate, or to toggle between 1024x768 @ 60 Hz and 720p @ 60 Hz:
Press and hold input buttons 1 and 3 simultaneously for approximately 3 seconds. The output rate becomes 1024x768 @ 60 Hz. Again
press and hold input buttons 1 and 3 simultaneously for another 3 seconds and the output rate becomes 720p @ 60 Hz.
NOTES: The output rate will subsequently toggle between 1024x768 @ 60 Hz and 720p @ 60 Hz every 3 seconds each time inputs 1
and 3 are simultaneously pressed and held for 3 seconds.

Output Scaler Rates
Output rates can be set using the OSD menu or SIS commands. The table below gives the most commonly used rates and the
corresponding SIS variables. See rear page for SIS command input.
The command to set the output rate is EX2!RATE}, where X2! is the output scaler rate as given in the example table below (* = default).
See the DSC 301 HD User Guide (available at www.extron.com) for the full SIS and output scaler rate details.
