Configuration 8 (18)
5.2 Extending the Recessive Bit
Due to the internal structure the CAN transceiver shortens recessive bits on the network, and
thus dominant bits are extended. At high bit rates this might cause errors. To extend the
recessive bits may improve the error rate, as the bits then are closer to their nominal value on
the network. If the recessive bits are extended with the DIP switches, the extension is made
independently of the bit rate, also at low bit rates.
► Use a screwdriver or similar tool to set the DIP switches.
► Extend the recessive bit with DIP switches 3 and 4.
