Hi, I am trying to use Wireshark 3.0.6 to decode Modbus RTU frames using a USB to RS-485 converter.
What I want is analyze the Modbus RTU frames that pass on the RS-485 between a Master and a Slave. The USB-Converter is connected to a laptop with wireshark.
Sometime appear on the wireshark capture some Modbus RTU frames, but they seems full wrong.
Someone with experience about Modbus RTU capture on Wireshark could help me to find the right setup ?
