Data transmission properties
Network topology
Linear bus, active bus termination at both ends, spur lines are possible
Medium
Screened twisted-pair cable, must be screened
Number of stations
32 stations in each segment without repeater.
With repeaters can be extended to 127
Max. bus length without repeater
100m at 12 MBit/s. Cable A: 200 m at 1500 KBit/s, up to 1.2 km at 93.75 KBit/s
Max. bus length with repeater
By using repeaters, the maximum bus length can be increased to around 10 km. There
should be at least 3 repeaters and, depending on the manufacturer, there can be up to
10.
