While programming, I recognized that there is a difference between the WaveForms SDK Reference Manual and the dwf.cs file provided in the samples.
Lines 23 - 26 are:
public const int devidADP3X50 = 6;
public const int devidEclypse = 6;
public const int devidADP5250 = 6;
public const int devidDPS3340 = 6;
I think they should be:
public const int devidADP3X50 = 6;
public const int devidEclypse = 7; // Not mentioned in the reference manual
public const int devidADP5250 = 8;
public const int devidDPS3340 = 9;
According to reference manual section 3 "Device Enumeration".
Best regards
