After the electrical installation of a charger is complete, follow these steps to configure the charger:





Select "Local controller" and then "Modbus RTU (RS485)" or "Modbus TCP/IP" depending on whether the charging station is connected to the via RS485 or Ethernet.
Modbus RTU (RS485)
Choose a unique Modbus address, different from all other Modbus addresses of devices on the same RS485 bus.
Choose baud rate 9600, parity Even, stop bits 1 and data bits 8
Modbus TCP/IP
You must set a fixed IP address in the charging station within the same network range as the .
Important: Always choose 502 as the server port.
For home and small business networks, a typical setup is with e.g. fixed IP address 192.168.1.50:
