Section 4. Setting up Datalogger Networks

Maximum Time On-Line – Enter 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.

Advanced
Extra Response Time – The amount of additional time, in seconds, that

LoggerNet should wait for this device to respond. Note that Extra Response

Time is cumulative for all devices in the network.

Delay Hangup – The amount of time, in seconds and milliseconds, that

LoggerNet should delay before hanging up the link to the device. If a new

command to the device is issued before the delay has expired, communication

will not be terminated.

Serial Ports
The Serial Ports tab is used to add all of the serial ports that are connected to

base modems that can be used to call this site. The dialing string entered in the

phone remote under the SerialPortPool must work in conjunction with any of

the modems connected to the serial ports added to the pool.
