PCAN-Ethernet Gateway FD DR – User Manual
49
accepts values from 1 to 128 and for a custom data bit rate, it
accepts values from 1 to 16.
Calculated bit rate: The form checks your entries and calculates the
bit rates using the following formula:
The Synchronization segment is always 1 and is used for the
synchronization of each bus node. The sampling time (sample
point) is determined via Time Segments 1 and 2. Time Segment 1
consists of Phase Segment 1 and the Propagation Segment. Time
Segment 2 is defined by Phase Segment 2.

Note: When entering values, the resulting bit rates are
automatically calculated in real time. If the values are incorrect,
or the calculated bit rates are beyond the limits of the CAN
transceiver, the data cannot be saved. For the nominal bit rate,
the limits are 20 kbit/s to 1 Mbit/s. For the data bit rate, the
limits are 20 kbit/s to 10 Mbit/s. The data bit rate must be equal
or higher than the nominal bit rate.
