Tip!
Repeaters do not have a station address but in the calculation of 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. In this case, the
maximum total bus system expansion depends on
ƒ the baud rate used
ƒ the number of repeaters used
