Entry-level DC PLC Module

This solution provides a simple way to prolong the reach of a single 1:1 serial RS232 communication line. The GreenPAK™ communication translator simply takes the serial input/output and interposes a high-frequency signal on the DC power line, which is in turn decoded by a second similar circuit.

System Benefits:

• Simple power line communication, transferring any UART data from/to a command station to the remote station over the power connection
• Simple UART connection between stations allows for adding proprietary protocols
• The featured DC/DC regulator allows running communications over a DC power line carrying a maximum 36V DC, while also powering the connected unit with the required low voltage for the MCU
