CR3000 Overview
to the CS I/O port) can be routed through that datalogger to the other
datalogger.
• Datalogger to datalogger communications – Special PakBus instructions
simplify transferring data between dataloggers for distributed decision
making or control.
All devices that send or receive messages in a PakBus network must have a
unique PakBus Address. The CR3000 default PakBus address is 1. In a
PakBus Network each datalogger must be set to a unique address before it is
installed in the network. To communicate with the CR3000, the PC software
(e.g., LoggerNet) must know the CR3000’s PakBus address.
OV2.6 Set up: Device Configuration Utility or Keyboard Display
When you receive a new CR3000 from Campbell Scientific it should be set to
the default PakBus address, 1. If you only have one PakBus datalogger, or will
only communicate with the CR3000 with a direct RS-232 or telephone modem
connection, there may be no need to change the address.
However, if a CR3000 has been in use or someone has borrowed it, you may
need to check what the address is or to set it or some other setting. While there
are a number of ways to do this, the two most basic are to use the Device
Configuration Utility (DevConfig) or the Keyboard display (see section
OV5.6). DevConfig comes bundled with LoggerNet and PC400 software and
is also available from the Campbell Scientific Inc. website
(www.campbellsci.com).
OV3. Device Configurator
The Device Configuration Utility (DevConfig) sets up dataloggers and
intelligent peripherals before those devices are deployed in the field and before
these devices are added to networks in Campbell Scientific datalogger support
software such as LoggerNet or PC400. Some key features of DevConfig
include:
• DevConfig only supports direct serial connections between the PC and
devices.
• DevConfig can send operating systems to supported device types.
• DevConfig can set datalogger clocks and send program files to
dataloggers.
• DevConfig allows you to determine operating system types and versions
• DevConfig provides a reporting facility where a summary of the current
configuration of a device can be shown on the screen and printed. This
configuration can also be saved to a file and used to restore the settings in
the same or a replacement device.
