Other Parts Discussed in Thread: ISO1044
When I am connecting a certain Number of CAN Nodes to the Network, the CAN bus does not work properly anymore. The reason is, as far as i know, that the output levels of the transceivers (Only ACK) are too high. With one device the bus still looks good. With each additional participant the ACK level becomes higher and higher.
This is a Problem, because of the static parasitic capacitance of the System the ACK Signal on the RX side is about 260ns longer than it should be. In Response, the CAN interface returns a bus error and the system does not work reliable.
How can I fix this issue?
Thanks a lot!

ACK Level too high, thus ther's a delayed RX Signal
