Hello I'm having a lot of troubles with a legacy project that has a NI9866 for LIN communication, from the NI-XNET Bus Monitor every time I start the bus I get the error message -1074384856 occurred at Check Runtime error.vi as possible reason that i'm trying to start an interace that is missing bus power for the transceiver.
But I've checked all the connections starting from:
1-Compact DAQ9811: Powered (V=20V,C=GND) [Power Led=ON]
2-NI9866: DB9 (pin9=12V->Vsup,pin6=GND->COM)
When I initialize everything the NI9866 LED1 is Solid Red as shown in the manual that means 'Open session on hardware, port is missing power.'
I've tried placing the DAQ different slots but I always get the same error.
I can Start the NI9866 as subordinate in the monitor bus even I have frames in the LIN bus nothing appears.
Any idea how to solve this? My NI9866 is broken??
