RFID Reader - Labview communication

[fadihajj]

Hello sir,

i am trying to check if their is a connection between my pc and the reader. So i ran the demo software then tried to run my VI, and i got an error at the VISA close vi. Does this mean that there is indeed a communication?

thank you

Not necessarily. If the error occurs at the open visa it will also appear at visa close.

You could run the vi in debug mode to see if all goes well in each step.

In the blockdiagram cmd line click on the debug lamp bulb. Then press the run button.

Hi Sir,

Actually i am not using an open VISA vi., i have the Write/Read vis initialized by the VISA configure vi.

But what i described above only occurs when i run my code in parallel with the demo software.

kindy find my vi attached.

Thank you,

Fady
