8.1.2 PHY Sniffer

The PHY Sniffer is an application example to monitor data traffic in the PLC network, then send it via serial communication to the Microchip PLC Sniffer PC tool (available on the Microchip website), which has to be installed in the user’s host PC to interface with the PLC board. This example requires one PLC board and a PLC network to be monitored.

This example uses the serial interface configured through UART/USART at 230400 bps or USB (depending on the PLC board; see the conf_board.h and conf_usi.h configuration files).
