How to configure Modbus RTU on ASCO 5210 Power Meter
RS-485 Port and DIP SW Settings
1. On J1, terminate twisted pair cable.
2. Set proper termination for S1 (Terminating resistor).
2.1 Terminating resistor should be ON if 5210 is the last device on the loop.
2.2 Otherwise, it should be OFF.
3. Choose 2-wire or 4-wire (S2).
3.1. For 2-wire, connect on any + or - terminals. Moving the DIP SW will internally connect the terminal. No need for external jumper.

4. On 5210 PM, go to Main Menu ➡ Settings ➡ Communication ➡ 485 Protocol..
5. Set protocol to Modbus.
6. Set appropriate baud rate and device address.
Please refer to the attached Power Meter Modus Register Map document (381339-307D ) for holding register addresses.
