2.3 Daisy Chain

Only quad channel card: The daisy chain can be activated via solder jumpers on the
board to connect a CAN-FD-optimized connection to an existing CAN bus. This makes
interference-free operation possible at higher CAN FD bit rates, because stubs and Y
distributions are avoided as far as possible.

2.3.1 Connection example and assignment

For cabling, the cables and connectors must be assembled accordingly.

The optional voltage supply for external devices can not be operated
simultaneously with the daisy chain.

When daisy chain is activated, the pin assignment is as follows:
