GPIB Virtual Disk mapped from Instrument

[Evenblij]

We use a USB GPIB interface to a certain measurement instrument. This instrument is quiet complex and has a build in DOS system with harddrive.

We are capable to connect a Labview application to the instrument and start measuring data, this works fine. However, the instrument allows to store data on the local harddrive. We are not able to retrieve this data from a Labview client.

My question is: does the Labview GPIB driver supports something like a virtual disk mapping to the client windows PC? For instance having a extra drive available in the windows explorer, just like what is available for PDA's through the USB connection.

Is there any information available on this?

Hi Evenblij,

No there is no such feature in the GPIB Driver since it is not part of the IEEE 488.2 standard, as for your instrument.

One USB device can emulate multiple 'devices', for example a USB Memory key with Wireless LAN or Bluetooth. I would imagine that if the instruments supports accessing it's local drive this will be implemented at the USB level and not the the GPIB level.

If this is the case then it is visual as a additional disk in Windows and you can access the files using normal file I/O functions in LabVIEW. You would need to check with the Instrument documentation or check with the manufacturer if the instrument has this capability. (Or else how you can access this local drive)

Hope this helps,

Thanks
