Hi!
We have an NI USB-232/4 hub that returns different serial numbers for the rs232 ports, see below.
NI USB-232/4 SN:41433A44
NI USB-232/4 SN:41433A44
NI USB-232/4 SN:14D5788
NI USB-232/4 SN:14D5788
Normally they have the same serial number so i wonder if it could be some hardware or internal software failure causing this?
We are using NI-Serial 4.1 and Measurement Studio 3013 on Windows 7 Ultimate.
Best Regards
