Good morning.
I ask you a (big) help with my crio 9075 and c-series module 9870.
I've installed NI-visa 5.4.0 and NI-serial rt 4.0 with 9870/9871 real time support. I can see them near the built in serial port under Devices and interfaces in Max.
If I use a 9870's port in a windows VI or deployng a VI on the c-rio and running it with labview everything works fine, but if I build an app to auto startup on the 9075, the crio can only see the built in port. For example if in my VI there is the "Visa find Resource" block, it returns an array with 1 element with the built-in port address (ASRL1::INSTR) intestead of ASRL1::INSTR/ASRL2::INSTR/ASRL3::INSTR/ASRL4::INSTR/ASRL5::INSTR that i find if i run the same VI by deploing the VI e run it. If I try to open a port with "Visa serial Open" i get an error (-1073807343). What can be the problem? I formatted and reinstalled everything a couple of time, and everything works when launching the app via labview. It can be some elettrical issue? An issue related to the build specification?
Sorry for my bad english. I would appreciate any help!
