Tom:
I happen to have the 4O3A Azimuth Magnetic Sensor but have yet to set it up. ?It is currently mounted on my KT-36 Triband yagi but have yet to place it in service. ?Your posting has rekindled my interest in perhaps utilizing the sensor.
Questions:
1. ?Which Waveshare ?RS485 to Ethernet User are you using??
2. ?With RS485, is it possible to ¡°share¡± the magnetic sensor with two RS485 interfaces? ?I¡¯m thinking of getting a RS-485 to USB adapter to connect to a PC in order to use the 403A software to display direction on a PC as well as utilize a RS-485 to Ethernet adapter for Node Red. ?I don¡¯t believe the 403A software on a PC will recognize an ethernet connection. ?
Thoughts/comments? ?
Thanks,

Hi everyone,
I'm new here, and I'd like to share a project I've been working on over the last four weeks.
For years, our club station has experienced issues with our Create rotors.
To address this, we decided to implement the 4O3A Azimuth Magnetic Sensor, which offers improved precision and reliability.
?I developed a Node-RED flow to read data from the sensor via the RS485 communication protocol.

I'm looking forward to receiving feedback or ideas on this project. Hopefully, it can help others solve similar challenges!
Best regards,
