Section 4. Setting up Datalogger Networks

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.

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

initiate a hello exchange with the datalogger. A verify interval of zero causes

LoggerNet to use a default verify interval of 2.5 times the beacon interval. If

the beacon interval is also zero, the default verify interval is 5 minutes.

The format for this field is 00 h(ours) 00 m(inutes) 00 s(econds).
