I am trying to use MATLAB to send commands to a Harvard Apparatus PHD Ultra pump using USB. I was told by the manufacturer that the best way to do this is to use the VISA protocol. I have the NI-VISA support package installed.
Here is the code I have been trying to use to connect to my device:
pump1 = visa('ni','USB::1FE9::1103::D-402110::INSTR');
When I run this code, I receive the error
Invalid RSRCNAME specified. Type 'instrhelp visa' for more information.
I am basing the resource name off of the serial number on my device and information found in the 'properties' section of the USB device in windows.
