 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.

By means of repeaters, you can establish line or tree topologies. The maximum total

dimension of the bus system depends on ...

• the used baud rate;

• the number of repeaters.
