The coupler can be used both as line coupler and as
backbone coupler. As a line coupler, it connects an
EIB line with a main line. As a backbone coupler, it
connects a main line with a backbone line. The
corresponding lines are then galvanically isolated
from each other.
A filter table determinies which telegrams are passed
through the coupler. With the LK2 coupler the
primary line is connected to a data rail, the LK2-2
backbone coupler. As a line coupler, it connects an
