17MeterBusTM Networking
3.1 Overview
The MeterBus
TM
Protocol is Morningstar’s proprietary messaging structure for communication
between Morningstar products. This protocol is used for communications between controllers and
meters, controllers and Relay Drivers, and for other inter-product data transfer.
Morningstar products supporting this protocol feature RJ-11 ports.
Setup a MeterBus
TM
network to:
display net system data for multiple controller systems**•
communicate with a TriStar Meter 2 or TriStar Remote Meter 2•
communicate with a Relay Driver•
**A Morningstar MeterBus Hub (HUB-1) and TriStar Digital Meter 2 (TS-M-2) or TriStar Remote Meter 2 (TS-RM-2) are required,
3.2 Networking Rules
3.2.1 General
Up to four Meter Hubs can be linked together, accommodating a maximum of 15 Morning-•
star devices on a single MeterBus
TM
network.
A maximum of two meters (of any model) are allowed on a single MeterBus•
TM
network.
Each device in the network must be programmed with a unique MeterBus•
TM
ID.
Ports 1-4 on the Meter Hub do not provide output power and are isolated from all other •
ports.
Ports A & B are not isolated from each other.•
A TriStar Meter 2 is required for MeterBus•
TM
network data display.
3.2.2 Power Management
Table 2 below lists all Morningstar Devices that can be networked using the Meter Hub. Table 2
is divided into two columns. Column A lists all devices that supply power to the MeterBus
TM
Net-
work. All devices listed in column B require power from the MeterBus
TM
Network to operate. It
is important to understand the power requirements of each device connected to a MeterBus
TM
network. Devices that require power from the network must be connected to devices that supply
power.
