Labview SCPI communication with GPM-8310

[Flynn12345]

Hello,

I am unable to communicate with the GPM-8310 in labview. I managed to get a reply no NI Max:

However I just get a timeout error:

Error -1073807339 occurred at VISA Read in Untitled 1

Possible reason(s):

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

Hi Flynn,

do you know the difference between "\r" and a CR char?

Do you really send the correct command to your device? Did you read it's manual carefully?

According to Google, the vendor has LabVIEW drivers. Maybe you should try them if you're having issues.

Also, since you are attempting to use backslash characters, show the display style (right click on the constant and show it). Then set it to show backslash characters. I think you're in for a surprise.

I know for a fact that they are not using backslash format display. Because if they did the space would show as \s not as a space!
