i have replaced a few of these, and i always downloaded the generic software that i got from a buddy. However one of my employees recently had to replace the board while i was not available, he had the UIT to adjust parameters etc, but was not sure about the big note on the board that says warning factory test software installed , download generic software. I said we have nothing to lose, give it a try with the factory test software . it worked fine, he was able to change the appropriate parameters with the UIT and it is still working. actually he has done this twice so far. just fyi might want to give it a try. if you really need to download the generic software, you will need a little adapter plug and the software, fairly easy to do. i have the part number for the adapter plug if you need it. pm me for more info
