PC Connection Methods
Personal computers can be used to access the system status and programming
features of the PV225S. A computer can be connected either directly or remotely.
1. Remote Connect - uses one of the three kits below.
• POTS Kit - uses a MultiTech® 56K Modem, RS232/Fiber Optic
Converter (configured for ethernet) and SA2 Surge Arrestor.
• Wireless Kit - uses a GSM Wireless Modem.
• Ethernet LAN Kit - uses a data communication device to enable the unit
to connect to a local area network.
2. Direct Connect - This method is used for troubleshooting. It uses a
RS232/Fiber Optic Converter (configured for a PC), a DB25-to-DB25 gender
changer, and a DB25-to-DB9 Serial Cable.
Software is included to provide a graphic user interface that relates important
system information. This software is called Xantrex Solar Graphic Interface
(GUI). See
"Computer Communications with the PV225S" in the PV225S 225
kW Grid-Tied Photovoltaic Inverter Operation and Maintenance Manual for
additional information.
The GUI can dial up the inverter and receive fault report calls from it through a
standard Hayes-compatible, landline modem. When the GUI initiates a call
through the modem at the GUI computer, the inverter’s modem answers the call
and initiates a 9600 baud serial connection, effectively as if the GUI was
connected directly. Or, if the inverter experiences a fault, it will initiate a call to
the GUI and report the fault details.
