65535. 
 
Select/Operate arm timer  
This is the time period after the select command is received when the operate command will 
be performed. Valid values are 0 - 65535 ms. This is not currently used. 
 
Baud rate  
This is the speed of the DNP serial port.  Values from 300 - 19200 baud can be set.  In most 
cases, this is the only parameter that will need to be set up. 
 
 
IMPORTANT Notes Relative to DNP Usage 
 
1.  Only the most recent channel data is available at the DNP port.  If a channel 
triggers multiple times (before being read by DNP), only the last one is 
retrievable with DNP. 
2.  Once data is read via Display Station software, the event log is cleared and the 
data will not be available at the DNP port.  This applies to “New Event” and 
“Recorder Faulty” status bits also.  The event could still be active, but will not 
appear at the DNP port once the event log is cleared.
