The Viessmann CAN bus is designed for "line" bus
topology with a terminator at both ends (accesso-
ries).
■
With CAN bus, the transmission quality and the
cable lengths depend on the electrical properties of
the cable:
–
Only use cable types listed in the following table.
–
Only use
one
cable type within a CAN bus.
