Connecting the bus cables
The incoming bus cable is connected to
terminals 1A and 1B. The bus cable for the next
device in the line is connected to terminals 2A
and 2B. If there is not another device in the
line the bus cable must be terminated with
resistors (switch set to ON).
In the ON switch setting terminals 2A and 2B
are switched off for the continuing bus cable.
