Model 8800 Series

GeoNet is a low-power, wireless data acquisition network developed to more efficiently collect data from many points. The system consists of a Mesh Supervisor (Model 8800-NA-SUP-232/USB) and any combination of Single-Channel VW Mesh Nodes (Model 8800-NA-01C-CBL/10P), Addressable Mesh Nodes (8800-NA-ADR-CBL) and/or 4- or 8-Channel Multichannel VW Mesh Nodes (8800-NA-04C-CBL or 8800-NA-08C-CBL). The supervisor controls the network and is the aggregator of all data collected by the nodes. The Multichannel VW Mesh Nodes expand the capacity at each node, allowing clusters of closely spaced sensors or vibrating wire load cells, multipoint borehole extensometers or multilevel piezometers to be added to the system. The system is compatible with all GEOKON Vibrating Wire instruments and addressable¹ sensor strings². GeoNet is built on top of the IEEE 802.15.4 standard. The network is self-healing and will reconfigure itself, if possible, to tolerate disturbances to the physical environment. This topology is more flexible than star networks, in that communication can be established around obstructions. Up to 12 networks can coexist by setting each to a different operating frequency (channel).

¹Addressable MEMS, VW and Thermistor strings. ²Analog sensor capability available soon.
