Specific to the selection of the serial protocol, four new fields will open directly under
the General DNP3 Master Settings panel. The new fields requiring input include Baud
Rate, Stop Bits, Parity, and Flow Control. The Baud Rate field is chosen by selecting
one of the values from the drop-down menu. The Stop Bits, Parity, and Flow Control
fields are radio buttons that require selection. (Data Bits is always set to 8, and it cannot
be changed.) Finally, click on the Save button to finalize the field edits. See Figure 54.

DNP3 Master 1
The DNP3 Master 1 panel allows updates to the DNP3 Address, IPv4 Address, Port,
and Unsolicited Response elds. After clicking on the Edit button, a dialog box
appears for specic eld inputs. The DNP3 address must be specied regardless of the
selection of TCP, UDP, or Serial transport. The Unsolicited Response eld is set to the
On position. The port value is used as the gateway’s local listen port when either TCP or
UDP transport is selected. Finally, the IP address eld is presently ignored. When either
TCP or UDP transport is selected, the gateway will accept trafc from any IP address
and will send responses to that same IP address. Click on the Save button to save the
modications. See Figure 55.
