2.3.2 Setting end jumpers
NOTICE! To ensure smooth running of the bus system, the jumper must be set on the first and last module.
When using a bus repeater, the two galvanically separated sub-networks must be considered separately. The
jumpers for each network must be set on the first and last module.

If the contacts at the base of the end jumper are not bridged (image left), it is referred to as “not set". In this
case there is no bus termination. If the contacts are closed (image right), the end jumper is set and the bus
connection is terminated.
