Select Mode of Operation: The DNP V3.00 Slave Driver implementation supports RS‐232 and RS‐485 (two and four
wires) over serial port communications as well as TCP/IP and UDP/IP over LAN/WAN communications. When the user
selects the Serial Mode, the TCP/UDP section is disabled. The same happens to the Serial section if the Mode of Oper‐
ation selected is TCP or UDP.
Serial: This section groups all the parameters needed to establish serial communication. When you select this
option, the following options will appear in the dialog window:
