Hi All,
We got in our lab a new pressure gauge JEVAmet VCU from JEVATEC company. This device allows cummincation through RS232 interface. I connected that device using RS232 cable to the PC and then, used a labview example (Continuous Serial Write and Read) to read the version number of the pressure gauge as a simple request, however, I always get the same error
Error -1073807339 occurred at VISA Read in Continuous Serial Write and Read.vi
Possible reason(s):
VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.
(see the attached photo). You can find the manual of such a device to check for the string command here https://jevatec.de/index.php/en/downloads/send/26-jevamet-vcu-en/90-ba-vcu-08-2017-en.
My attempts to solve the problem:
1- increase the timeout duration ------- failed (increasing the timeout did not solve the problem)
2- Changing the port instead of RS232 to convert it to USB using RS232 hub ---- failed
3- restart the device ---- failed
4- Changing the baud rate and check the new baud connection ------ failed
5- Check for the code display ----- failed
What is the problem I am facing here?
