Note!
The permissible cable lengths must be observed.
1. Check the compliance with the total cable length in Tab. 4−1.
The baud rate determines the total cable length.

Tab. 4−1 Total cable length
2. Check the compliance with the segment cable length in Tab. 4−2.
The segment cable length is determined by the cable cross−section used and the
number of nodes. Without a repeater, the segment cable length corresponds to
the total cable length.

3. Compare the two values detected.
If the value detected from Tab. 4−2 is smaller than the total cable length to be
provided from Tab. 4−1 , repeaters must be used. Repeaters divide the total cable
length into segments.
