1. SC-3H Windows™ Software Installation
1.1. General
The SC-3H is controllable via free Windows® based software available from the Hall
Research website. All of the device features, and more, are accessible and controllable
from the GUI.
1.2. Software Installation Prerequisites
A PC with Windows XP® OS or later
USB port
Microsoft® .NET Framework 3.5 or later (most recent OS including Windows 8
and later include this software and no action is required). If the .NET
Framework 3.5 or later has not installed on your PC, the Microsoft™ website
has free downloads available.
1.3. Software Installation
If an earlier version of this software was installed, UNINSTALL it first from either the
Add/Remove Programs section of the control panel or by running the previous
installation’s SETUP.EXE and selecting “remove application”.
Install the software by executing the SETUP.EXE program from the installation
source directory
Accept the default settings, but if you want to specify a particular installation
directory other than the default, you may do so.
Once the SC-3H software installation has completed, either click the desktop
icon or navigate the Start Menu to
Start -> Programs -> Hall Research -> SC-3H Switcher
2. Using the Software
2.1. General
For most installations the use of the software GUI is not required as most functions
can be performed using the front panel buttons on the product.
The software GUI allows the user to customize many of the SC-3H features to help
with installation issues and usage.
You can use the software to import/export EDID files from the device. Custom EDID
data can also be written to devices connected to the output if they support that
function.

User’s Manual

It is possible to connect more than one SC-3H to the PC (using several USB ports of
the PC). The same software GUI detects all connected devices and allows control
from the same application.
2.2. USB Device Detection
The SC-3H software uses standard Windows® drivers, which automatically
configure the USB port after connection and do not require the installation of any
special USB drivers.
The first time you connect the SC-3H to the PC, you may experience a short delay
and a windows notification pop-up message may be shown. Typically, this happens
only once.
2.2.1. The software GUI scans the SC-3H settings continuously in real time, all
device changes are reflected on the software GUI.
2.2.2. If no SC-3H device is attached to the system, the on-screen fields are
disabled (grayed out).
2.2.3. Only one instance of the software GUI can run at a time. Attempting to
execute the application more than once will result in a warning message.
