I've been trying for a few days now with no luck to control a Newport ESP300 motion controller with NI-VISA through RS232. It seems like it should be straightforward, but everytime I try, I get this:
Read Operation
Error
VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.
This started with trying to use Python and pyVisa to control it, but I get the same error there. Am I missing something obvious? Any help is appreciated!
