RTS On : 6 #Set RTS On delay value from 0 to 65535 milliseconds
The parameter label is "RTS On" and the parameter value is 6. The characters
after the parameter value are ignored and are used for internal documentation of
the configuration file.
Any record that begins with the '#' character is considered to be a comment
record. These records can be placed anywhere in the file as long as the '#'
character is found in the first column of the line. These lines are ignored in the file
and can be used to provide documentation within the configuration file. Liberal
use of comments within the file can ease the use and interpretation of the data in
the file.
Sections of the configuration file that contain lists of data are formatted
differently. Each list begins with the label START and ends when the END label
is reached. When entering the list data, make certain that the first character in
each line is left blank.
2.2.1 [Module]
Module Name
0 to 80 characters
This parameter assigns a name to the module that can be viewed using the
configuration/debug port. Use this parameter to identify the module and the
configuration file.
2.2.2 [DNP Slave]
This section provides information required to configure a slave application with
the module. Most entries contained within this section are self explanatory with
the possible exception of the Use IP List directive. This directive instructs the
module to verify the address of the received message and ignore the message if
it is not on our list of acceptable clients. Another item of concern is the maximum
size of the total database, although it is possible to configure a database of
considerable size, this would not work, as the maximum Class 0 request may not
exceed 2048 bytes in size.
The following example shows a sample [DNP Slave] section:
# This section is used to define the configuration for the Module.
# port. This port will receive requests from a remote DNP master unit.

[DNP Slave]
Internal Slave ID : 6 #0-65534 slave identification code for this unit
# DNP slave communication port configuration
Baud Rate : 19200 #Baud rate for port 110-115200
RTS On : 0 #0-32000 mSec before message
RTS Off : 0 #0-32000 mSec after message
Min Response Delay : 0 #0-32000 mSec before response sent from slave
# DNP slave modem configuration
Modem : No #Use a dial-up modem on this port (Yes or No)
