  • NI-9862
  • NI-9853

Driver

  • NI-XNET

Issue Details

I get Error -1074384856 when I try to run an XNET application with ni NI-XNET hardware, or when I run the Bus Monitor. How can I fix this?

Solution

As the error pop-up shows, it will come up if your interface should receive external power. 
  • If you are using a CAN Breakout Box you should make sure it is powered and all the cables are properly connected.
  • If you are using a custom connection to the CAN network, make sure to check your XNET hardware's manual to see the diagram of how the connection should look like. 

Additional Information

For example: 

Say you are trying to read out of the NI-9862 High-Speed CAN Module.
On the Getting Started Guide of the module, you will find the following diagrams of the pin assignments in the module, and the hardware overview. :
This means that you will need to connect the positive terminal of the external power supply to the Pin 9 of the CAN port and connect the COM pin 6 or 3 to the negative terminal.
