Hi,
I am trying to communicate with a vacuum gauge controller, Varian XGS-600 via RS232.
When I use NI-MAX or LabVIEW for that matter, I have to repeat every command twice before getting the correct reply. It is as if the previous reply is still stuck in the buffer. I would like to emphasize that this happens only using NI-MAX or LabVIEW.
When I use teraterm directly to the COM port, no such error occurs - whatever I enter the device "gets in" immediately and I do not have to repeat the command twice.
I did not change any of the default settings in teraterm, nor in NI-MAX. Do you have any idea where the problem lies?
Thank you,
Amit
