Hi baloss
If I understand you correctly, then you're able to see the remote device in MAX and to test the functionality of the board with the Testpanel. If this is the case, then the board is OK and the RDA Server is running properly too. There must be a problem in CVI. Error -10403 means, that the specified device does not support the requested action (the driver recognizes the device, but the action is inappropriate for the device). Have you tried to run your programm on the PC where the 6025 resides? That's a fast way to see if the problem is related to your application.

Luca
