MODEL 8800 SERIES GEONET WIRELESS DATA ACQUISITION NETWORK | INTRODUCTION | 1
1. INTRODUCTION
GeoNet is a low-power wireless data acquisition network, designed to efficiently
collect data from many points. GeoNet is especially helpful in geographically-
complex locations where a wired infrastructure would be expensive or even
impossible. The system consists of a network supervisor unit, single- and/or
multi-channel node units, and Agent software. Nodes collect battery and
temperature data, and will read either GEOKON's vibrating wire gauges or
GEOKON's addressable sensors, depending on its configuration For information
regarding the installation and use of Agent software, please see the appropriate
product manual.
FEATURES:
■Supercapacitor eliminates data blackout during battery replacement
■Modular, configurable design
■Aluminum enclosure for enhanced ruggedness and weatherproofing
■900 MHz radio band
■Up to 12 networks per area (using unique channels)
■Up to 2 years of data storage
■Operates with alkaline or lithium batteries.
1.1 NETWORK SUPERVISOR
The network supervisor unit controls the network and collects all data from the
nodes. The supervisor reads battery and temperature data, but it does not
possess sensor-reading functionality. Data stored by the supervisor may be
collected using Agent software or a Modbus client.

TABLE 1: GeoNet Model Identification
1.8 NETWORKS
GeoNet uses network technology that is self-configuring and self-healing. If all
nodes are in range of the supervisor, then data from the nodes is sent directly
from the nodes to the supervisor (a star topology).
If direct communication is not possible for some nodes, then other nodes will
automatically relay their data to the supervisor. This effectively creates a cluster
tree topology. The figure below illustrates this concept.
8:
FIGURE 8: Cluster Tree Network Topology
Each transmission from node to supervisor or node to node is considered one
"hop". Examples of hops are shown in figures above and below. Up to four hops
can be made between a node and the supervisor. With the ability to hop comes
the ability for the supervisor to communicate with nodes that have not

established direct radio communication. The figure below shows how GeoNet
devices can operate around buildings or other barriers using hops.
9:
FIGURE 9: Working Around Obstructions
When using GeoNet, it is important to understand the effect that obstructions
have on radio signals. Obstructions between two antennas can cause reflections
of the transmitted signal. When these reflections arrive at the receiving antenna,
they may be in or out of phase with the signal that took a straight-line path. This
reflected signal may act as constructive or destructive interference with the
received signal. For optimum performance, GEOKON recommends creating as
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.
The figure below illustrates the Fresnel zone.

FIGURE 10: Fresnel Zone
If communication cannot be established when GeoNet is deployed to a site, it
may be necessary to elevate the devices or their antennas, or to move them to a
location where a radio link can be established. This may require extending the
readout cable of the attached sensors, or connecting an antenna cable
extension.

2. NETWORK INSTALLATION
Review the GeoNet Installation Tutorial available at the GEOKON website, https://
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. The necessary steps include:
1. Configure the channel.
2. Mount the device.
3. Install the antenna.
4. Install the batteries.
5. Connect the sensor(s).
6. Seal the enclosure.
2.1.1 CONFIGURE THE CHANNEL
Channels allow multiple networks to coexist in the same area. All devices are set
to communicate on Channel 1 from the factory; this is all that is required for
operating a single network in a given area. However, if multiple networks are
within radio range of each other, then the networks must be set to different
channels, and devices of each network must be set to their respective channel.
TO SET THE CHANNEL ON A NODE OR SUPERVISOR:
1. Open the device by unscrewing the four captive screws on the front of the
enclosure. Ensure that no dirt, water, or other contaminants are allowed to
enter the enclosure.
2. Set the channel select DIP switch (shown in the figure below) to any of the
twelve valid positions listed in Table 15 in Appendix C.
11:
FIGURE 11: Channel Select Switches

8| NETWORK INSTALLATION | GEOKON
3. Press the Reset button.
12:
FIGURE 12: Reset Button
4. Devices will communicate only with others that have been set to the same
channel. To prevent erratic behavior, there can be only one supervisor on a
particular channel. Supervisors in radio range of each other must operate
using different channel settings.
2.1.2 MOUNT THE DEVICE
The built-in mounting plate is designed to be used with U-Bolts, hose clamps,
screws, bolts, etc. Devices should be mounted vertically, with the antenna
pointing up.
Select the mounting location with care. Certain mounting configurations can
hinder or even completely block wireless signal transmission. See Appendix G.
2.1.3 INSTALL THE ANTENNA
Remove the rubber cap from the antenna mount. Position the antenna on the
mount and then rotate the antenna in a clockwise direction until tightened.
2.1.4 INSTALL THE BATTERIES
When replacing batteries in an existing network, ensure that the network is in
deployment mode prior to removing the batteries. See Section 5.3 for more
information on battery replacement.
INSTALL THE BATTERIES AS FOLLOWS:
1. Open the device by unscrewing the four captive screws on the front of the
enclosure. Ensure that no dirt, water or other contaminants are allowed to
enter the enclosure.
2. Set the three-position battery select switch to the OFF (middle) position (see
the figure below).
13:
FIGURE 13: Battery Select Switch

MODEL 8800 SERIES GEONET WIRELESS DATA ACQUISITION NETWORK | NETWORK INSTALLATION | 9
3. 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.
14:
FIGURE 14: Battery Detail
4. Move the battery select switch to either the Alkaline or Lithium position
depending on the type of battery being used.
5. An LED will flash on the right side of the box indicating the unit has power.
2.1.5 CONNECT THE SENSOR(S)
To connect a sensor:
1. Open the device by unscrewing the four captive screws on the front of the
enclosure. Ensure that no dirt, water or other contaminants are allowed to
enter the enclosure.
2. Loosen the nut on the cable fitting and remove the white plastic dowel.
3. Slide the transducer cable through the cable gland nut and fitting.
4. Insert each conductor wire into the terminal block by pressing down on the
orange tab, inserting the bare end of the conductor into the terminal block,
and then releasing the tab. Refer to Figure 15 and Table 2 for sensor wiring
information. To prevent the possibility of a short circuit, do not allow bare
leads to touch each other during or after wiring.
TABLE 2: Node Wiring
5. Pull gently on each conductor to ensure it is secure.
6. Tighten the cable gland nut until it firmly grips the outer jacket of the cable.
The cable gland nut must be properly tightened to prevent water entry. Do
not over-tighten, as this might strip the plastic threads.
7. Pull gently on the sensor cable to ensure it is held in place by the cable
gland.
2.1.6 SEAL THE ENCLOSURE
After the batteries have been installed, complete the following with the
supervisor and the node units:
1. Place the supplied desiccant packs inside the enclosure.

2. Ensure the cover gasket and the mating ridge on the enclosure are clean,
and that the gasket is properly seated inside the groove on the cover. Place
the cover on the unit.
3. Tighten the cover screws a little at a time, working in a diagonal pattern.
Make sure the cover seals tightly and evenly.
4. Mount the device. The built-in mounting plate is designed to be used with
U-Bolts, hose clamps, screws, bolts, etc. Devices should be mounted
vertically, with the antenna pointing up.
2.2 DEPLOYMENT MODE
There are two modes of operation: Deployment mode and Normal mode. The
supervisor and node units all enter Deployment mode upon power up or system
reset. Perform a system reset by either pressing the blue Reset button on the
GeoNet circuit board, or by pressing and holding the Status button on the side
panel for 10 seconds.
For information on the function of the Status button, see Section 2.3.
Deployment mode allows nodes to be added to a network and verified quickly.
When the network is in Deployment mode, the network status will be indicated
by the LEDs on the supervisor every 10 seconds.
In Deployment mode, the supervisor and node units will find each other in less
than three minutes, radio circumstances permitting. Once the network has been
established and the network time has been set, the Supervisor's green LED will
flash simultaneously with the green LEDs on the nodes. If the network time has
not been set, the Supervisor's red LED will blink in unison with the nodes. The
time must then be set using the Agent software.
If the correct lights do not illuminate, or if the network has exited Deployment
mode, press the Status button on the supervisor to restart Deployment mode.
2.2.1 ADDING NODES
While in Deployment mode, nodes may be added by simply turning them on
within radio range. When adding nodes, start with those closest to the
supervisor. Place the supervisor in the center of the distribution of
nodes if possible (see Figure 16 below); doing so will reduce the number of
hops, which will reduce battery consumption.
Move nodes to their installation locations as long as the green LED is flashing.
Pay attention to the LEDs while moving the nodes to ensure the signal isn’t lost.
After 10 minutes, the LEDs on the nodes will stop indicating their status in order
to conserve batteries. Pressing the Status button on a node will reactivate the
LEDs for another 10 minutes.
The default time a network will remain in Deployment mode is one hour. When a
new node joins the network the timer will reset, extending the deployment
period for another hour. If more time is needed while deploying nodes, the
default deployment timeout may be changed using Agent software.
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.
