[5-6] Number of stations
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.
