1. INTRODUCTION

GeoNet is a low power, wireless, data acquisition network, designed to efficiently collect data
from many points. GeoNet is especially beneficial in geographically challenging locations where
a wired infrastructure would be expensive, if not impossible. The system consists of a Network
Supervisor, Sensor Nodes, and Agent Software. (For information regarding the installation and
use of Agent Software, please see the appropriate product manual.)
Features:
• Worldwide operation at 2.4 GHz or select countries at 900 MHz
• Up to 100 Nodes per network (Fewer with the use of GeoNet multiplexers, see Section 3.)
• 12 channels available
• Each Node is capable of storing more than one million data arrays
• Operates with alkaline or lithium batteries

1.1 Sensor Node

Sensor Nodes collect battery and temperature data and will read any of
Geokon's vibrating wire sensors. Each Node can read one sensor by
itself, or up to eight sensors when connected to a GeoNet Multiplexer.
Nodes ship with the following accessories:
• One 2.1 dBi omnidirectional antenna (For other antenna possibilities,
please contact Geokon technical support.)
• Two D cell batteries
• Four desiccant packs

1.2 Network Supervisor

The Supervisor controls the network and is the aggregator of all data
collected by the sensor Nodes. While the Supervisor is similar to the
Nodes in that it will read battery and temperature data, it does not
accommodate a vibrating wire sensor. Data stored by the Supervisor
may be collected by using Agent software or any other Modbus
master. (For information regarding the use of Modbus with GeoNet
hardware please see Appendix D.)
Supervisors ship with the following accessories:
• Two D cell batteries
• Set of two screwdrivers, one Phillips Head and one Flat Head
• Four desiccant packs
• One firmware upgrade cable
• One RS-232 or USB communications cable (depending on the
model purchased)
• One 2.1 dBi omnidirectional antenna (For other antenna
possibilities, please contact Geokon technical support.)
