Hello everyone. so, i just started project to learn Magnetic Guide Sensor. i know i need to use RS485 from manual pdf for CCF-NS16-4M. But, until now, i still couldn't figure it out how to read the data from sensor to mega trough RS485. Is anyone know reference program code or tutorial to use it. i need it so much. thank you

Search for "arduino rs-485" and see if you can find an adapter to interface between your Arduino and your sensor. Then the communications are just like any other serial communications.
i've tried it several times, modbus interface with rs485, but it seems doesn't work because i always end up with blank serial monitor. i was using Serial1 for the communication, and Serial for printing
You have failed to tell us that you already have the adapter.
So what sort of Arduino are you using?
RS485 is normally a half duplex circuit, that is at any one time it is either transmitting or receiving. So how have you wired your RS485 adapter to your sensor?
What software are you using to communicate down the RS485?
Did you read and understand that link I posted?
We can only know what you tell us.
