Installation
Electrical installation
If no repeater is to be used at the end of the segment, the bus must be terminated by
means of a bus terminating resistor at the last station (S). The bus termination is supplied
by this station.
An external supply of the communication unit provides for a supply of the bus termination
independent of the supply of the controller.

 Tip!
Repeaters do not have a station address. When calculating the maximum number
of stations, they reduce the number of stations by 1 on each side of the segment.
Repeaters can be used to build up line and tree topologies. The maximum total bus
system expansion depends on ...
• the baud rate used;
• the number of repeaters used.
 Note!
The bus terminator must always be supplied. Otherwise, the bus can get
unstable.
