Can´t see AD 7760 in MAX

[Rashek]

Hi All,

I am trying to control AD7760 board along with EVAL-CED1Z. I installed appropriate drivers for it and after connecting to my PC through USB, I see device working correctly in device manager. Hovewer, NI MAX doesn´t detect it, nor can I see it in LabVIEW. Any suggestions on what might be wrong?

I'd recommend trying to work through this KB to start. It goes over a few steps to try and get MAX to see the USB device.

After installing driver from Analog Devices and finding Labview code for it, I managed to transfer data. Hovewer, communication is managed via DLL, which is quite unreliable. Still, it manages to communicate with the ADC, but I wasnt able to discover any way, how to communicate with it on low level, namely, the VISA still doesnt show connected device.

Hi Rashek,

Here is a KB that outlines troubleshooting steps for when VISA doesnt show connected USB devices:
