InfoRS485 Wiring
- For correct RS485 wiring: follow the RS485 wiring guidelines.
- If the wiring shown in the table below is incorrect, please let us know.
- There is no general industry consensus on the use of A and B for RS485 polarity, so the naming may be counterintuitive for some devices.
NoteNote
Ensure the termination resistor is set correctly if the charger is at the end of the RS485 bus.
After the electrical installation is complete, you need to configure the charger using the Raedian App.
- Download the Raedian app from the App Store or Google Play Store.
- Open the app and register/login.
- Add the charging station via Bluetooth/Wi-Fi following the in-app instructions.
- Once connected, navigate to the Settings menu (usually represented by a gear icon).
To allow the Sofar EMS to control the NEO charger via Modbus RTU:
- In the settings menu, look for Communication or Modbus Settings.
- Enable Modbus RTU.
- Configure the following parameters:
- Address (Slave ID): Set a unique address (e.g., 1). This must match the configuration in the Sofar EMS.
- Baud Rate: 9600 (Recommended)
- Parity: None
- Data Bits: 8
- Stop Bits: 1
- Save the settings and reboot the charger if prompted.
To allow the Sofar EMS to control the NEX charger via Modbus TCP:
- Ensure the charger is connected to the same local network as the Sofar EMS via Ethernet or Wi-Fi.
- In the app settings, go to Network Settings.
- It is highly recommended to assign a Static IP to the charger to ensure connectivity remains stable after power outages.
- IP Address: Choose a free IP in your network range (e.g., 192.168.1.50)
- Subnet Mask: 255.255.255.0
- Gateway: Your router IP (e.g., 192.168.1.1)
- Enable Modbus TCP in the Communication settings.
- Ensure the Port is set to
502.
