Hi Lab130,
have you tried that AH2500-vi on your AH2550 machine? Have you ask the vendor of the machine for LV drivers?
Have you looked into the manual of the AH2550 if there are (big) changes to the AH2500? Most often you can use the same vi for different models of measurements devices of the same brand...
Best regards,
GerdW
