PCAN-Basic 07 example 'heavy'/'warning' error

[tn1314]

Hello, I am new to CAN protocol. There is something wrong with my example...
Here are the results from the Code and PCAN-VEIW Trace tabs.
I'm wondering if it's a hardware problem or a software problem.
Thank you.

Hello,

The picture shows a BUSHEAVY status and CAN error frames. Please check that:

1. you have your device connected to a CAN network with at least one additional CAN node (CAN needs at least two nodes for communication).
2. you use a termination resistor on both ends of your CAN cable.
3. you are using the same bit rate configuration for all CAN participants, i.e. the same bit rate register.

If all these points are taken into account, the communication should work without problems.
