We have reached the Next Level – Cantrace 3.17 Released
This release adds playback of log files to the CAN bus, which can be used for simulation, testing and bus traffic generation. Any log file in ASC format can be used to generate data on the CAN bus. For those working with J1939 this release adds masking of priority bits in J1939 databases. This allows using the default priority in the database, while still matching messages on the bus that uses a different priority. This feature works well with the included J1939 database, which in this release has been enhanced with the DM1 and Address Claimed messages, which are common in J1939 networks. Read more

One should remember with the CAN physical layer that there exists only impedance, not plain conductors. Let us start with a brief review of the main important transmission line characteristics.
Despite of the comprehensive knowledge of the CAN physical layer, there is poor tradition in design of physical layer structures for industrial and machinery CAN networks. Cables with “wrong” impedance (not matching with termination) are commonly used and many engineers intentionally select them, because of constrained understanding of the transmission line behavior. Most engineers forget, that the transmission line cannot be considered as conductor with DC characteristics only. “Wrong” impedance leads not only to unmanaged reflections but also to different wave propagation speed in the cable. Unmanaged reflections increase the bit-error probability of the network and the propagation speed difference makes bit timing analysis results invalid. Read more
