    Introduction

    This is a simple RS232 to RS485 converter that is self powered using the TX, RX or RTS, CTS signals for power. The RS232 is DB9 female connector, and the RS422 side is a DB9 male or 4 position terminal block.

    It is able to convert RS232 signal to RS485 balanced differential signal and extend the communication distance to 1.2km,

    It is passive and doesn't require external power.

    It is compatible with DFRobot's URM04 ultrasonic sensor
