README for the 2253 and the 953 Sensoray products.

Important Note: 

If you do not run setup.exe to install the latest SDK, you must update the drivers.
There are 2 driver files.  Please run dpinst.exe from the driver directory to update both
drivers.  The device (if plugged in) should be unplugged and plugged back in to load
the new firmware after the drivers are plugged in.
c:\program files(x64)\sensoray\2253\driver


The DLL and ActiveX components must also be updated if setup.exe is not used for re-distribution. 
These are found in c:\program files(x86)\sensoray\2253\API
