This converter allows connecting RS232 devices to RS485 networks. Perfect for communication projects.

What you need

• Arduino
• RS232 RS485 Converter
• TX/RX Lead

Steps

1. Connect the converter to your Arduino using the TX and RX pins of the microcontroller.
2. Check the pin configuration on the datasheet for the 4-pin adapter.
3. Install the necessary library to manage RS232/RS485 on Arduino.
4. Write the sketch that establishes communication between two devices through the converter.
5. Verify the transmitted data using a serial monitor or another connected device.
6. Test the bidirectional functionality of the converter by sending and receiving messages.
7. Configure settings as needed, such as enabling/disabling the common RS485 line.
8. Verify that the converter works correctly in both directions.

Example code

Serial.begin(9600); // Imposta la velocità di trasmissione
while (Serial.available() > 0) {
   char incoming = Serial.read();
   Serial.print("You sent:");
   Serial.println(incoming);
}
