DNP3 Settings
There are three fields can be chosen for DNP3 setting: Mode, Address Table, and Advanced Setting. The default DNP3 listen
port is 20000, and user can change it to other ports. In general, the MGate passively accepts connections from DNP3 masters or
outstations; meanwhile, the MGate also supports actively connections to DNP3 masters or outstations.

Address Table
Address Table provides user to add the destination IP address and the DNP3 start/end address for the station to be
communicated. When a DNP3 packet is received from network or serial side to the MGate, the MGate will route it to the defined
destination according to the Address Table. If the destination is on serial side, the packet is sent to the corresponding serial port.
If the destination is on network side, and the TCP connection to the destined station is already established, the DNP3 packet will
be routed to that station. If the connection is not yet established, the MGate will establish a connection to the destined station and
then send DNP3 packet to that station.
The MGate will automatically generate the setting of serial port in address table. Users have to modify the setting of serial port by
one clicking on the current shown DNP3 serial column and click Edit for modification.
