3.5 Multi-TriStar Network Set-Up
Multiple TriStar controllers can be networked together using a
Morningstar MeterBus Communication Hub (HUB-1) and
RJ-11 cables. Networking controllers together on a MeterBus
network allows one or more TriStar digital meters to com-
municate with all controllers on the network. This enables the
display of total system data on the meter. Additionally, each
individual controller’s data may be viewed in separate menus.
To install a TriStar Meter in a MeterBus network, follow these
steps in order:
Step 1 - Program Unique MeterBus Addresses
Each device on the MeterBus network must have a unique
MeterBus address. All TriStars have a default MeterBus ad-
dress of 1. Choose a controller to be controller #1 and mark
it with a pen or sticker. This controller will keep the default
MeterBus address 1.
There are two ways to program the remaining TriStars with
unique addresses. If a meter and TriStar PWM controller have
beenupdatedwithcurrentrmware,MeterBusaddressescan
be assigned via the meter. Address programming can also
be done through Morningstar’s MSView PC software. TriStar

from the TriStar Meter 2 Advanced Set-Up menu. Instructions
for both methods are provided.
