Table 118. CR800 Settings
Settings are accessed through the Campbell Scientific Device Configuration Utility (DevConfig) via direct-serial and IP connections, or through
PakBusGraph via most CR800 supported telecommunications options.
Setting Description Default Entry
OS Version Specifies the version of the operating system currently in the CR800.
Serial Number
Specifies the CR800 serial number assigned by the factory when the CR800 was
calibrated.
Station Name Specifies a name assigned to this station.
PakBus Address
This setting specifies the PakBus® address for this device. The value for this setting
must be chosen such that the address of the device is unique in the scope of the
datalogger network. Duplication of PakBus® addresses in two or more devices can lead
to failures and unpredictable behavior in the PakBus® network. The following values
are the default addresses of various types of software and devices and should probably
be avoided:
Device PB Address
LoggerNet 4094
PC400 4093
PC200 4092
Visual Weather 4091
RTDAQ 4090
DevConfig 4089
NL100 678

Security Level 1
Specifies Level 1 Security. Zero disables all security. Range: 0 to 65535. See Security
(p. 70).
0
Security Level 2
Specifies Level 2 Security. Zero disables levels 2 & 3. Range: 0 to 65535. See Security
(p. 70).
0
Security Level 3
Specifies Level 3 Security. Zero disables level 3. Range: 0 to 65535. See Security (p.
70).
0
UTC Offset
The offset, in seconds, that the CR800's local time is from UTC. This offset is used in
email and HTML headers, since these protocols require the time stamp to be reflected in
UTC. This offset will also be used by the GPS instruction, NetworkTimeProtocol
instruction, and DaylightSavingTime functions when enabled.
-1 (Disabled)
Is Router
This setting controls whether the CR800 is configured as a router or as a leaf node. If
the value of this setting is non-zero, the CR800 is configured to act as a PakBus
®
router.
That is, it is able to forward PakBus
®
packets from one port to another. To perform its
routing duties, a CR800 configured as a router will maintain its own list of neighbors
and send this list to other routers in the PakBus
® network. It will also obtain and receive
neighbor lists from other routers.
If the value of this setting is zero, the CR800 is configured to act as a leaf node. In this
configuration, the CR800 will not be able to forward packets from one port to another
and it will not maintain a list of neighbors. Under this configuration, the CR800 can still
communicate with other dataloggers and wireless sensors. It cannot, however, be used
as a means of reaching those other dataloggers. 0
PakBus Nodes Allocation
Specifies the amount of memory that the CR800 allocates for maintaining PakBus ®
routing information. This value represents roughly the maximum number of PakBus
®
nodes that the CR800 is able to track in its routing tables.
