Signal Delay
The PCAN-Repeater has a transit time delay of 115 ns. This
corresponds to a cable length of 23 m. Therefore, you should
consider the dependence of the maximum length of a CAN bus on
the bit rate at the installation of the repeater. The following table
shows the maximum possible CAN bus length at different bit rates:
