Agent software. Nodes collect battery and temperature data, and will read either 's vibrating wire gauges or GEOKON 's addressable sensors, depending on its configuration For information GEOKON regarding the installation and use of Agent software, please see the appropriate product manual. -
Page 12: Single Channel Node
An addressable node will read any RS-485 addressable sensor. Each GEOKON addressable node can read up to the following limits on the RS-485 bus: ■ 16 addressable MEMS sensors ■ 24 addressable VW sensors ■ 80 addressable temperature sensors 2 | INTRODUCTION | GEOKON... -

Page 15: Figure 9: Working Around Obstructions
For optimum performance, recommends creating as GEOKON much vertical space as possible between the straight-line path and obstacles, including the ground. The Fresnel zone must be at least 60% obstruction-free to ensure optimal wireless communication. -
Page 16: Figure 10: Fresnel Zone
This may require extending the readout cable of the attached sensors, or connecting an antenna cable extension. 6 | INTRODUCTION | GEOKON... -
Page 17: Network Installation
NETWORK INSTALLATION Review the GeoNet Installation Tutorial available at the website, https:// GEOKON www.geokon.com/tutorial-videos. Select the mounting location with care. Certain mounting configurations can hinder or even completely block wireless signal transmission. Refer to Appendix G for more information. 2.1 SETTING UP THE NETWORK A network must include the supervisor and at least one node that is within radio range of the supervisor. -
Page 18: Mount The Device
Ensure that no dirt, water or other contaminants are allowed to enter the enclosure. Set the three-position battery select switch to the OFF (middle) position (see the figure below). FIGURE 13: Battery Select Switch 8 | NETWORK INSTALLATION | GEOKON... -
Page 19: Connect The Sensor(S)
Install the batteries by aligning the positive (+) side of the D cells with the + indicator in the battery holder. Push the batteries straight down into the holder. FIGURE 14: Battery Detail Move the battery select switch to either the Alkaline or Lithium position depending on the type of battery being used. -
Page 20: Deployment Mode
The network will not begin collecting data until the network time is set. To do this, use the Agent software (or other Modbus master). The default scan interval for data collection is 10 minutes. 10 | NETWORK INSTALLATION | GEOKON... -
Page 21: Status Button Functionality
If isolated from the rest of the network, a node will continue to sample and store data. When communication is reestablished, it will "catch up" by sending all of the collected data to the supervisor. FIGURE 16: Installation Order 2.3 STATUS BUTTON FUNCTIONALITY All GeoNet devices have red and green LED indicators to display their status. -

This is also best practice when replacing batteries in nodes. Replace D cell batteries when their measured voltage drops below 2.0 VDC. Replace external 12-volt batteries when the measured voltage drops below 11 VDC. 16 | MAINTENANCE | GEOKON... - Page 27 All data is retained in nonvolatile flash memory. Data will not be lost even if the batteries are removed for an extended period (e.g., years). REPLACE THE BATTERIES AS FOLLOWS: Place the network in deployment mode by pressing the status button on the Network Supervisor.
