3.2 Earth Ground

An earth grounding lug is supplied on the exterior of the Micro-800 enclosure to connect the
system to earth ground (Figure 3). A grounding rod can be driven (or other suitable attachment to
earth utilized) to ground the system and provide a path to earth for protection against a lightning
strike or other transient voltage. A 6' to 8' copper grounding rod connected to the Dataloggers
grounding lug with a large gauge wire (12 AWG or larger) is recommended. The earth ground
connection should be made as close to the Datalogger as possible.

3.3 Gages

At this time the vibrating wire sensors can be connected to the multiplexer. Please refer to
Appendix F for the appropriate connection description.

3.4 Communications

Standard communications with the Datalogger is established by connecting the supplied serial
cable to the RS-232 port (Figure 3) and the COM port on a computer, or a USB port on the
computer by using the provided USB to Serial converter cable.

4. SOFTWARE

The Micro-800 Datalogger is operated by a download file that is generated by a software
program. The software package the MICRO-800 Datalogger may be supplied with is either
MultiLogger software (developed by Canary Systems, Inc., New London, NH) or LoggerNet
software (developed by Campbell Scientific, Logan, Utah). Please refer to the manual supplied
with the software for instructions on installing the software and creating the required download
file for datalogger operation.
