Figure 5-3 10Base5 System Basic Connection Method - Hitachi S10mini User Manual

5 USER GUIDE
In the example shown in Figure 5-3, the maximum inter-node distance is 2500 m. A link cable (the
maximum length is 500 m when the cable is coaxial) having repeaters on both ends is used to
increase the transmission distance. A segment formed in this manner is called a link segment.
No node is to be connected to a link segment. However, the portion enclosed by dotted lines,
including the repeaters on both ends, can be counted as one repeater unit. Therefore, you can raise
the limit on the total number of repeaters between nodes.
