Communication Connection
5.7.1 Interfaces Overview
All communication terminals are located on the bottom of the inverter.
There are two kinds of optional connection ports on the communication circuit
board: RS485 serial communication with RJ45 ports (RS485-1/2) and Ethernet
communication with RJ45 ports (NET-1/2).

Communication Terminals
For RS485 serial communication, the inverter operation information can be
transferred via RS485 ports to a PC with query software, or to data logging device
(such as MC Logger).
For Ethernet communication, the inverter operation information can be
transferred via NET ports to a PC with query software, or Webserver, or to
SolarInfo Bank via the router.
Before communication connection, prepare communication cables and RJ45 plug.
Cable requirements to ensure quality of communication:
Shielded network cable
DI and DO connection cable
A converter such as RS485-232 converter or SolarInfo Logger, which
converts 485 signal to 232 signal, is needed between the inverter and PC.
