Isolated, Single-Channel RS232 transceiver (Isolated RS232 to UART)

https://www.electronics-lab.com/isolated-single-channel-rs232-transceiver-isolated-rs232-to-uart/

The project presented here provides an isolated interface between the RS-232 cable network and the connected UART systems to protect against voltage spikes and ground loops within the noisy environment and improve system reliability. The project achieves a robust data communication link in harsh industrial environment. ADM3251E chip from Analog Devices is the heart of […]
