2.5 Optional Accessories
The following accessories are available for purchase separately from your authorized
Morningstar dealer:
TriStar Digital Meter 2 / TriStar Remote Meter 2 (Models: TS-M-2 / TS-
RM-2)
The TriStar Digital Meter mounts directly on the TS-MPPT controller, replacing the wiring box
cover. The TriStar Remote Meter can be flush mounted in a wall or into a standard duplex (2-
gang) electrical box. A 2 x 16 character display shows system operating information, error indica-
tions, and self-diagnostic information. Four (4) buttons make navigating the meter menus easy.
For systems where multiple TS-MPPT controllers are networked together, one (1) meter can
display full system information. The TriStar meters connect to the RJ- 11 MeterBus
TM
port on the
TriStar-MPPT.
Meter Hub (HUB-1)
A Morningstar MeterBus
TM
network with multiple controllers requires a Meter Hub for electri-
cal isolation. The HUB-1 allows communication between MeterBus
TM
compatible Morningstar
products, including the TriStar MPPT 150V controller. DIN rail compatible. See section 5.2 for
more details.
Relay Driver (RD-1)
The Relay Driver
TM
accessory enables the TriStar MPPT 150V to control external devices. Four
(4) relay control ports can be configured (in various combinations) to perform the following tasks:
•
generator control (2-, 3-, and 4-wire configurations)
• dry contacts for alarms and other signals
• advanced load control
• vent fan control
• DIN rail compatible or surface mount
For more information on the Relay Driver, visit our website at www.morningstarcorp.com or in-
quire with your local Morningstar dealer.
EIA-485 / RS-232 Communications Adapter (RSC-1)
Connect one or more TriStar MPPT 150V controllers to a PC or to other serial devices using the
RSC-1 EIA-485 adapter. The adapter converts an RS-232 serial interface to EIA-485 compliant
signals. An LED shows network activity and errors. DIN rail compatible.
Ethernet Meterbus Converter (EMC-1)
The EMC-1 acts as an Ethernet gateway that serves MODBUS IP, local Web pages, and Web
Monitoring Services. Note that the Web Monitoring Service is not currently available. The
EMC-1 supports any product with a MeterBus port by bridging MODBUS TCP/IP requests
between an Ethernet connection and a connected Morningstar device.
USB Communications Adapter (UMC-1)
A modular unit that uses a USB-B plug, usually from a USB A-B computer cable, and an RJ-
11 plug to connect with a Morningstar controller's MeterBus port, for monitoring and custom
programming using MSView PC software.
