The maximum length allowed for spur lines connected to the bus cable
is 6 meters. The overall length of the bus cable including all spur lines
is not to exceed the maximum length listed in the table below.
The maximum cable length depends on the baud rate and the cable
type used.
Baud rate Cable type Cable length
125 kBit/s 2 x 1.1 mm 500 m
2 x 0.6 mm 100 m
250 kBit/s 2 x 1.1 mm 250 m
2 x 0.6 mm 100 m
500 kBit/s 2 x 1.1 mm 100 m
2 x 0.6 mm 100 m
