Segment cable length

2. Check that the segment cable length is not exceeded

The segment cable length is determined by the number of nodes and the cable

cross-section used. Without a repeater, the segment cable length corresponds to

the total cable length.

[5-2] Segment cable length

3. Compare both values.

If the value determined from the Segment cable length

[5-2] table is smaller than

the required total cable length Total cable length

[5-1], repeaters must be used.

Repeaters divide the total cable length into segments.

Selection example

Based on the given specifications, the following cable lengths/number of repeaters result

for a maximum of 63 nodes:
