Bus Errors (Switch Position 2) - Maretron N2KMeter User Manual

7 Bus Errors (Switch Position 2)

The N2KMeter tracks network data transmission errors in real-time, and lets you know if the
error rate is acceptable
undesirable (although your network may still function since CAN automatically retransmits after
errors). An error rate greater than 10/s indicates a problem that should be investigated.
The N2KMeter uses unique technology to accurately determine which node was attempting to
transmit when a bus error occurs.
Display
NOTE: Node error measurements only include errors known to have occurred when the node is
transmitting. Frames with corrupt ID fields, and frames that cannot be attributed to specific nodes
are not included in node measurements. It is common for the sum of per-node results to be less
than the overall network values.
