To establish a connection with the NP5-02, proceed as follows:

1. Plug in the NP5-02 at X8.
2. Unplug jumper X13.
3. Set potentiometer P2 to 0 (counterclockwise as far as it will go)
4. Switch on the termination resistor (switch SW3 of the Modbus board to ON).
5. Connect your RS485 cable to X2 of the Modbus board.
6. Connect your supply voltage to X7.
