Section 4. Setting up Datalogger Networks
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 – Select the arrow to the right of this field to choose a
maximum baud rate for communication with this device. Note that the actual
rate of communication may be limited by the capability of other devices in the
communications chain.
Advanced
Extra Response Time – In this field, specify the additional time that
LoggerNet should delay before terminating the communications link if there is
no response from the MD9. Additional time may be needed in instances where
the communications link is noisy or network traffic is heavy.
Maximum Packet Size – Data is transferred in “chunks” called packets. For
most devices the default value is 2048 byes. The value entered in this field can
be changed in 32 byte increments. If a communications link is marginal,
reducing the packet size may improve reliability.
4.2.4.14 RF400
If the RF400 is being used in a point-to-point network (one base radio to one
remote radio) or in a PakBus network, where all of the settings in the radios are
identical, then the communications link can be depicted on the device map as a
direct connection (COM Port with datalogger or PakBus routing device
attached — no RF400s shown in the device map). However, in a point-to-
multipoint network where all remote radios have a separate address, the
RF400s are depicted on the device map. Refer to the RF400 Users Manual for
complete information on RF400 radio setup.
The RF400 has only Hardware and Notes tabs.
Standard
Communication Enabled – Before communication can take place, all devices
in the chain must be enabled. When this box is selected, the RF400 radio is
enabled for communication.
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
