Issue Details

I have a NI-CAN or NI-XNET device that I'm using, but I'm not sure whether I need an external power supply or not. Is there a list of which devices are internally or externally powered?

FlexRay Devices:

NI-XNET FlexRay Device (PXI-8517) is Internally Powered. 
 

Additional Information

  • When using XNET transceiver cables with an NI 9860 C series module, the NI 9860 itself must also be powered externally (9-30V), in addition to bus power requirements shown in the table. Details can be found in the NI 9860 Getting Started Guide.
  • When using XNET transceiver cables with a PXIe-8510 or cDAQ-913x controller, only the bus power requirements shown in the table are necessary.
  • When using XNET device who does not need any external power supply the trasceiver will not power the entire BUS so if you have a setup that involves one device that requires a power supply CAN BUS you must provide it externally.
