Issue Details

When I test my NI LIN device with a LabVIEW XNET example, I see a clean LIN output signal. However, when I test my LIN device with a LabWindows™/CVI XNET example, the signal is attenuated and causes intermittant communication failures. 

Solution

Additional Information

The NI-XNET shipping examples are not identical in LabVIEW versus LabWindows™/CVI. The LabVIEW XNET examples have the Interface:LIN:Termination property enabled by default to terminate in software, while the LabWindows™/CVI XNET examples require either hardware or software termination.
