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.
