Experiment Setup: Connect three wires (Tx, Rx, Gnd) over a distance of 30m to 50m between two devices. Observations: At 19200 bps, you may notice some unintended signals or "noise" detected by the receiver. Lowering the baud rate to 9600 bps typically reduces this interference. For added reliability, consider reducing the cable length by half to accommodate unforeseen interferences and maintain signal quality. By following these guidelines, you can ensure your RS232 connections are robust and efficient, minimizing disruptions and maximizing data integrity.
