Adding a Geokon Geonet
1. Make sure you have turned on a single gateway THREAD that is within range of the Geonet node. How to Add a thread can be found within the link.
2. Attach the antenna to the Geonet Node
3. Confirm the Dipswitch settings are preconfigured to the sensemetrics option snipits from the manual are below. The full Geokon Geonet 8800 manual can be found here.
4. Prior to installing the D cells, ensure that the battery select switch is set to the “OFF” position (Figure 8). (For units manufactured prior to June 2017, move the battery select switch to the OPPOSITE setting of the type of battery that will be installed.)
Prior to June 2017:
5. Insert the batteries
6. Toggle the switch to the Position to turn it on. The LED on the right side should flash once. After roughly 2 minutes of boot cycle the Geonet will go into "Hunt Mode". The Geonet will look for a Thread every 10 minutes and then revert to the default hourly reading frequency.
This completes the initial connection of a Geonet node onto the sensemetrics platform.
The Geonet Nodes will use the mesh network to connect to your gateway THREAD and to your sensemetrics application. You will see the nodes populate on the connections side of the Connectivity module.
Modifying Sampling and Reporting Interval
1. Now that the Geonet(s) have been added, the Geonet can remain in the default state of 60-minute reporting interval and 60-minute sampling interval which means the Geonet will take one reading at the top of the hour and send that reading at the same time.
2. The Geonets' reading intervals and reporting intervals can be customized to match the project needs. These parameters are changed in the configuration page of the Geonet which is accessed by navigating to the device in the Devices & Sensors list on the right-hand side of the Connectivity module and then clicking the Node you wish to configure.
3. Within the configuration page of the node are two drop downs that specify Sampling Interval and Reporting Interval.
Sampling interval is how frequent the node will take a reading. The sampling interval can be set to the following settings.
- 60 secs
- 5 mins
- 15 mins
- 30 mins
- 60 mins
Reporting interval is how frequent the node will send these readings to sensemetrics. The reporting interval can be set to the following settings.
- 15 mins
- 30 mins
- 60 mins
- 2 hours
- 4 hours
- 8 hours
- 12 hours
- 24 hours
To elaborate, if a Geonet node is set to 5-minute sampling interval and a 60-minute reporting inteval then readings will be taken every 5 minutes and then at the top of every hour, the 12 readings taken in the previous hour will be uploaded.
Note: If a node is set to an extended reporting interval (e.g. 24-hour reporting interval) any new changes won't be applied until the Geonet connects to sensemetrics again.
Vibrating Wire Configuration
1. The Vibrating Wire Sensor on the Geonet will now need to be configured to the specific VW sensor you are using.
2. Navigate to the device in the Devices & Sensors list on the right-hand side of Network and click the Node you wish to configure.
3. Click the "Edit Configuration" button under VW Channel Information.
4. Within the configuration modal, the input type, sensor category, and sensor type for each channel must be specified, in that order. Dependent on each selection, different parameters will be available for selection.
5. Click Apply when finished and make sure to click Submit within the configuration page to write the settings.
6. Once saved, the configured vibrating wire sensor will populate beneath the Geonet Device and can be viewed by clicking the drop-down arrow.
Additional calibration factors and other parameters will need to be entered for some types of vibrating wires, see the Vibrating Wire article for details.
