Section 4. Setting up Datalogger Networks
TCP Password – This is a password that is used to control IP access to a
datalogger. Passwords are assigned through the Device Configuration Utility
or through the datalogger’s settings which can be edited through PakBus Graph
or the Device Configuration Utility.
New PakBus Nodes Tab
The New PakBus Nodes tab displays the address and device type of PakBus
devices that LoggerNet has discovered (from direct communication or from the
routing table of another device), but are not yet added to the network map.
Select a PakBus port in the device map and press Start Search to have
LoggerNet query the network for devices. When a device is found, its PakBus
address will be added to the Node PakBus ID column. When Get Device Type
is pressed, the type of device (e.g., CR1000, CR10X-PB) will be displayed in
the Device Type column. To automatically add a device to the network map,
highlight it and press Add To Network Map. The datalogger will be added to
the network as the correct device type and PakBus ID.
4.2.4.18 PakBus Router
A PakBus Router can be another datalogger, an NL100, or any other device
that can be assigned a PakBus address and handle PakBus communication in a
datalogger network.
Standard
Communication 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 router.
PakBus Address – The address of the device in the PakBus network. Valid
ranges are 1 through 4093.
Advanced
Maximum Packet Size – Data is transferred in “chunks” called packets. The
default value is 1000 bytes; however, the value entered in this field can be
between 32 and 2048 bytes, in 32 byte increments. If a communication link is
marginal, reducing the packet size may improve the success rate.
PakBus Encryption Key – This setting specifies text that will be used to
generate the key for encrypting PakBus messages sent to or received from this
device. The key entered here must match the PakBus Encryption Key setting in
the device. (The device setting is entered using DevConfig, PakBus Graph,
Network Planner, or a CR1000KD.)
The PakBus Encryption Key can be up to 63 bytes long and can include any
character with the exception of the Null character. Note that if Unicode
characters are included in the key, those characters may take up to three bytes
each.
If the PakBus Encryption Key device setting is specified as an empty string, the
device will not use PakBus encryption. If the PakBus Encryption Key device
setting is specified as a non-empty string, however, the device will not respond
to any PakBus message unless that message has been encrypted. AES-128
encryption is used.
