Select Mode of Operation:
The DNP3 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 Operation 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 appear in the dialog window:
Serial Port:
Select serial port device name from provided drop-down list for serial connection. Options
are: ttyS1(RS232) and ttyS5 (RS485).
Enable Collision Avoidance:
The DNP3 Slave Driver can be configured to enable or disable collision
avoidance. The collision avoidance method implemented is Detection of Transmitted Data with a
random pre-transmission back-off time, as recommended by the DNP3 Technical Bulletin 9804-007.
TCP:
This section is enabled when the Mode of Operation selected is TCP. The parameters to be

value is 20,000. This parameter is used in both TCP and UDP protocol.

This section is enabled when the Mode of Operation is set to UDP. The parameters to be configured
are:
