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.
