2. Make sure the reference board is NOT connected to your computer when you install
software.
3. If not already installed, install the .NET Framework 1.1 on your computer.
To download the latest version of the .NET Framework 1.1, visit the following Microsoft
Developer Network (MSDN) Web site:
http://msdn.microsoft.com/netframework/downloads/updates/default.aspx
OR,
Run 'Windows Update' and select the '.Net Framework 1.1' option.
4. If not already installed, install DirectX Version 8.1 or greater.

downloaded from:
http://ffdshow-tryout.sourceforge.net/
6. Run 2246API.exe file on the CD to install the 2246 demo program.
(See Dialog box figures 1 - 7)
Dialog figure 5 shows the default installation directory "C:\Program Files\Sensoray\2246"
7. After software installation is completed, connect USB cable to 2246 board and to USB
port of the host computer.
The 2246 multiplexes two USB channels onto one physical USB cable and each channel
requires a boot driver and a functional driver. Thus, when the 2246 is detected by the
computer for the first time, five drivers will need to be loaded.
o A USB Hub driver for multiplexing the USB channels
o A Initialization driver for Channel 1 - 'SENSORAY 2246 EZ LOADER 1' (Optional)
o A Initialization driver for Channel 2 - 'Sensoray 2246 EZLOADER 2' (Optional)
o A functional driver for Channel 1 - 'Sensoray 2246 Control'
o A functional driver for Channel 2 - 'Sensoray 2246 A/V Capture'
8. Power on the 2246
WARNING
Care must be taken to insure the user is ready to install all five drivers as they are asked
for. If the user cancels installation before finishing, an invalid default driver will be loaded.
If this happens, the entire USB device must be re-installed to allow the Hardware Wizard
to again cycle through all five drivers.
