encryption is used.
4.2.4.19 PakBusPort HD
This virtual device is used to facilitate communication with a PakBus
datalogger in an RF95 or RF232 radio network or in an MD9 network.
Standard
Communications Enabled – This check box is used to turn communication on
or off. This check box must be enabled for any communication to take place
over the PakBus node.
Maximum Time On-Line – This field is used to define a time limit for
maintaining a connection to the device. (This may be useful in avoiding costly
communication costs, in the event that a connection to a station is inadvertently
maintained for a long period of time.) Maximum Time On-Line applies to both
scheduled connections and manual connections. However, for manual
connections from the Connect Screen, it is always best to manually disconnect
rather than relying on LoggerNet to disconnect for you.
When the device is contacted on a schedule, communication with the device
will be terminated once this time limit is exceeded. A value of 0 in this field
indicates that there is no time limit on maintaining a connection to the device.
When the device is connected in the Connect Screen and the time limit
approaches, a dialog box is displayed warning the user that Max Time On-Line
is about to be exceeded. The dialog box has Reset Max Time and Don’t Reset
buttons. If the Reset Max Time button is pressed, the Max Time On-Line
counter will be reset. If the Don’t Reset button is pressed or if no button is
pressed, the connection will be terminated when Max Time On-Line is
reached.
The format for this field is 00 h(ours) 00 m(inutes) 00 s(econds).
If you are using LoggerNet Admin or LoggerNet Remote 4.0 and
using the Connect Screen to connect to a remote server that is
running an older version of LoggerNet, the behavior will be
different than described above. When connecting to a LoggerNet
3.4.1 server, you will be disconnected with no advanced warning
when Max Time On-Line is reached. A message will be
displayed indicating that Max Time On-Line has been reached.
When connecting to servers older than LoggerNet 3.4.1, the
behavior will be variable. Generally, you will be disconnected at
some point, but the timing of the disconnect will not be
predictable.
NOTE
Maximum Baud Rate – The maximum baud rate at which communication
will take place with this device.
PakBus Verify Interval – The amount of time, in seconds, that will be used as
the link verification interval in the PakBus hello transaction messages. If no
communication has taken place during the specified interval, LoggerNet will
