Networking and Communication
5.4 EIA-485 (formerly RS-485)
NOTE:
The RS-232 and EIA-485 ports share hardware. Both ports cannot be used simultaneously.
EIA-485 is a networking standard for serial communication between multiple devices on a bus.
The TriStar MPPT 600V communicates over an EIA-485 network via the open standard MOD-
BUS
TM
protocol. Use EIA-485 networking to:
• connect multiple TriStar MPPT 600V controllers on a network to log and view real-time
data using MSView
TM
PC software
• program each controller on the network with custom charge settings using MSView
TM
PC
software
• connect the TriStar MPPT 600V to other Morningstar controllers with the RSC-1 Serial to
EIA-485 Adapter (sold separately)
• bridge an Ethernet connection through a TriStar MPPT 600V to an EIA-485 network
The EIA-485 port has four (4) connections: Power, Data A, Data B, and Ground. Data A & B are
differentially driven data lines that carry the network data. Power and Ground connections pro
-
vide power to the network. The TriStar MPPT 600V does not supply power to the EIA-485 net-
work, therefore an external power source is required. The source voltage must be between 8-16
Vdc.
!
CAUTION: Equipment Damage
Tapping power off of individual batteries in a series string of batteries can cause a voltage imbalance.
Damage to the batteries may result. Always use a DC-DC converter to power the EIA-485 network.
!
PRUDENCE : Endommagement de l’équipement
L’arrêt progressif de batteries individuelles dans une série de batteries peut provoquer un déséquilibre
de tension. Les batteries peuvent être endommagées. Utilisez toujours un convertisseur CC-CC pour
convertir l’alimentation au réseau EIA-485 si la tension nominale du système est supérieure à 12 V.

CAUTION: Risk of Tampering
The TS-MPPT-600V does not feature built-in network security. It is the responsibility of the user or
network administrator to place the TS-MPPT-600V behind a network firewall to prevent unauthorized
access.
!
PRUDENCE : Risque de tentative d’altération
Le TS-MPPT-600V ne comporte pas de sécurité réseau intégrée. Il incombe à l’utilisateur ou à
l’administrateur du réseau de placer le TS-MPPT-600V derrière un pare-feu réseau afin d’empêcher
l’accès non autorisé.
The Ethernet port supports HTTP, MODBUS TCP/IP
TM
, SMTP, and SNMP protocols to provide
a fully web-enabled interface between the TriStar MPPT 600V and a LAN/WAN network or the
internet.
Some of the features the Ethernet connection provides include:
• program custom settings with MSView
TM
PC software
• monitor the controller from a web browser
• modify controller settings from a web browser
• log and monitor the system with MSView
TM
PC software anywhere on the internet
• create custom web pages to show system data
•
send an email or text message if a fault, alarm, or user-defined event occurs
• monitor and receive messages on an SNMP network
This section provides a summary of each of the features. For detailed information about Ethernet
connectivity and networking, refer to the “

Network Information
Connect to the TriStar MPPT 600V via an Ethernet network (LAN/WAN) or connect the controller
directly to a PC using an Ethernet cross-over cable. Use CAT-5 or CAT-5e twisted pair Ethernet
cables with RJ-45 connectors. A network diagram for both scenarios is shown in figure 5-3 below.
