6.2.2 Modbus Communication Protocol
ZIGOR SOLAR XTR3 team enables communication via Modbus RTU, ASCII and TCP.
The selection of the desired protocol can be done in the inverter´s display.
ZIGOR SOLAR XTR3´s communication card has a RJ45 Ethernet input, through which we can
communicate the inverter to a computer using Modbus TCP and SNMP.
The communication card has two RJ11 jacks for communicating with Modbus RTU and ASCII. With
these 2 pins we can make a daisy chain configuration.
The polarization of the RJ11 is shown below in the following table:
