3.9 Light Codes Unrelated to Normal Operation

3.9.1 Green Light On for One Second then Off for One Second

Bootloader is activated.
1) Remove batteries
2) Change channel switches to a valid setting
3) Reinsert batteries

3.9.2 Green Light Flashing Quickly (Twice per Second)

This is a known issue. Update the network firmware to version 160816 or later

3.9.3 Green and Red Light Alternating

Device malfunction, contact Geokon.

3.10 Node Will Not Join Network

1) Ensure network is in deploy mode; a light on the supervisor should flash every 10 seconds.
2) Ensure channel is the same as the rest of the network.
3) Restart node closer to other nodes or supervisor to establish link and then move back to
desired location while using lights to observe signal strength.
3.11 No Data From Node
1) Be sure node is powered.
2) With network in deploy mode, observe either red and green or green lights every 10 seconds
on the node.
3) Make sure network time is set.
3.12 Some Data Present (e.g., Battery/Signal Strength) but No Vibrating Wire
Sensor Data Available
1) Check the sensor wire connections to the node terminal if so equipped.
2) If the node has been operating without a sensor connected, it will stop trying to read a sensor
after five failed scans. Set the network time or change the scan rate to re-enable the node.
3) Check the sensor with an independent measurement device, like a GK-404 or GK-405.
