3.4.2 Addressing

To enable devices on the network to communicate with each other, each one must be assigned

a unique MeterBus

ID. Only 15 devices are allowed on a single network, therefore, the range

of acceptable MeterBus

IDs is 1 to 15. There are two manners in which you can assign these

addresses: using a TS Meter/TS Remote Meter or by using a PC.

NOTE: Morningstar recommends using a TS Meter 2/TS

Remote Meter 2 for addressing due to its simplicity and

speed.

3.4.2.1 Meter or Remote Meter (TriStar / TS-MPPT only)

A TriStar Meter is capable of addressing each TriStar device on the MeterBus

network before

they are connected. Attach the meter to the device you want to address and use the TS-M 2 / TS-

RM 2 manual and meter map to set the desired MeterBus

ID.

Do this for all the TS controllers on the network, making sure that no two devices have the same

address. Two devices with the same address will cause communications problems on the net-

work and unexpected behavior will result.

3.4.2.2 PC Connection (all devices)

A PC can be used to individually connect and assign MeterBus

IDs to Morningstar products.

This is accomplished through the use of Morningstar’s MSView

software package. For informa-

tiononhowtoinstallandconguredevicesusingMSView

, please refer to Section 5.0.

All devices on the network, except for the Meter Hub and TS Meters, need to be programmed

individually. Connect to the network devices one by one and use the MSView

software to as-

sign IDs that are unique on the network. MSView

’s Setup Wizards are an invaluable tool for this

task.

Make sure no two devices have the same ID on the network. Two devices with the same address

will cause communications problems and unexpected behavior will result.

3.4.3 Verication

Use a network Meter (TS-M 2 or TS-RM 2) to view data for each controller/inverter on the net-

work. Make sure that all network devices are accessible through the meter and that aggregate

meter data is an accurate account of the system as a whole.
