PM100A optical power meter

[lacorgui]

Hi everybody, 

Does anyone how to implement PM100D drivers (or VISA) in order to achieve power using a PM100A optical power meter from Thorlabs?? I found some examples on the web (examples) but I´m not able to use them because no device is recognized 

I will receive different wavelengths and I need to know how much power is my sample receiving. 

Thanks in advance for all your help!
