Issue Details

I am using NI-XNET device, such as the NI-8502 to communicate with other devices. When receiving in signals, I notice that my NI device stops receiving new data. However, I am able to output signals properly from my NI device. What do I need to consider to fix this communication problem?

Solution

The communication of your CAN device may not be working due to improper termination.
  • Make sure you are terminating your CAN signals properly. Check out the CAN Physical Layer and Termination Guide.
    • You can programatically add termination for┬áNI-XNET high-speed/FD and software-selectable/FD CAN interfaces when needed.
