7.6 CR800 Configuration
The CR800 ships from Campbell Scientific to communicate with Campbell
Scientific datalogger support software
(p. 76)
via RS-232. Some applications,
however, require changes to the factory defaults. Most settings address
telecommunication variations between the CR800 and a network or PC.
Note The CR800 is shipped factory ready with all settings and operating system
necessary to communicate with a PC via RS-232 and to accept and execute user
application programs when using Campbell Scientific datalogger support
software.
7.6.1 Device Configuration Utility
Device Configuration Utility, or DevConfig, is the preferred tool for configuring
the CR800. It is made available as part of LoggerNet, PC400, RTDAQ, or at
www.campbellsci.com. Prior to running DevConfig, connect a serial cable from
the computer COM port or USB port to the RS-232 port on the CR800 as shown
previously in figure Power and RS-232 Connections
(p. 44).
DevConfig can:
• Communicate with devices via direct RS-232 or ethernet.
• Send operating systems to supported device types.
• Set datalogger clocks and send program files to dataloggers.
• Identify operating system types and versions.
• Provide a reporting facility wherein a summary of the current configuration
of a device can be shown, printed, or saved to a file. The file can be used to
restore settings, or set settings in like devices.
