Figure 4. Medium-sized Network
The Medium-sized network shown in fi gure 4 includes three TriStars,
one Relay Driver, and two meters. There can be a maximum of two
meters on the MeterBus network. The Relay Driver requires power from
the MeterBus. Since ports 1 through 4 on the Meter Hub do not provide
output power, a TriStar powers the Relay Driver before connection to
Port 1.
