Device power requirements will sometimes call for a network setup as illustrated in Figure 21.
This multiple hub network connects hubs in a different manner than in Example #4. Since the
TriStar (with Meter) can only power up to three devices (Meter, Hub, Relay Driver - denoted 1
through 3 in the diagram), the output link of the Relay Driver cannot be connected to the input of
the second hub. Another unit that provides power (i.e. TriStar) is used to power the second hub
and TS Remote Meter. To network the two hubs, the output link of the Relay Driver (3) is con-
nected to one of the isolated ports on the second hub.
Figure 21 illustrates only one example of the way these 14 units can be networked together.
