2.9 Termination
The termination of the Main-Channel has been set to OFF by default. If the ProfiHub is the last device
on the segment, the termination must be set to ON (
Fig. 15 ).
The termination of the Channels have been set to ON by default, because it is assumed that the new
segment is started at the ProfiHub (
Fig. 15 ).
The termination LED of the corresponding Channel is activated when the termination switch is set to
ON.

When the DB9 connector is used and the cable starts at the ProfiHub, it is recommended to
use the termination on the DB9 plug and NOT the ProfiHub. This way, the connector can be removed
while maintaining termination on the bus.
