Figure 3-3. A medium-sized network with 3 TriStars, 2 meters, and a
Relay Driver.
TriStar 1 provides power to the hub and Remote Meter.
•
TriStar 2 powers the Relay Driver and TriStar 3 powers the Local
•
Meter. It is good practice to distribute the network meters and
Relay Driver as shown to avoid loading a single TriStar with all of
the network accessories.
All three TriStars are isolated from each other in this system.
•
NOTE:
Information is shared across the entire MeterBus
network. A meter can be connected anywhere in the
system and will always show full aggregate system
information as well as information about each con-
troller on the network. This is true regardless of the
meter model (TS-M-2 / TS-RM-2).

Figure 3-2. A simple two TriStar system with Remote Meter.
TriStar 1 provides power both to a hub and to a single Remote
•
Meter connected to Output Power Port A.
TriStar 2 is connected to Port 1 on the Hub and is electrically
•
isolated from TriStar 1.
NOTE:
Electrical isolation protects controllers, cables, and
other system equipment from damaged due to poor or
disconnected system grounds.
