To connect the HRC12 Bluetooth Module to your genset controller, you will need to follow these steps:
1. Locate the RS485 port on your genset controller.
2. Connect the RS485B(-) wire terminal of the HRC12 module to the RS485B(-) port on your genset controller using a 0.5mm2 cable.
3. Connect the RS485A(+) wire terminal of the HRC12 module to the RS485A(+) port on your genset controller using a 0.5mm2 cable.
4. It is recommended to use a 120Ω terminal matched resistor between the RS485 ports for optimal communication.
5. Once the connections are made, the HRC12 module will be able to obtain genset information from the genset controller.
Please refer to the "RS485 Connection" section in the user manual (Fig. 2) for a visual representation of the wiring connections.
