4.7 Shutting Down the Network
The network shut down procedure is:
• Turn off the gateway
• Close the operator terminal and shut down the computer
• Pick up and power off the nodes.
5 Trouble Shooting Guide
Network State Unknown
With pre-production release hardware and GUI system, the network may occasionally go into
Network State: Unknown status. This is a very infrequent condition that can be dealt with in
the following manner.
• Close the operator terminal program on the control computer.
• Power cycle the gateway (turn power off, wait 5 seconds, turn power on)
• Once the gateway has acquired GPS, restart the Operator Terminal program.
• Reset the system as mentioned in Section 4.6. Do this even if the Network State says
it is in the “Reset” state.
• Resynchronize and Restart the system as if it were an initial start up.
If nodes are not joining the network after this process, see the section below on “Some or all
of the Nodes do not join the network”
Sensors will not power up
• Check to see if the batteries are installed correctly
• Change batteries
• When pressing the ON/OFF button, reposition your finger to a better angle.
Sensors do not appear to be detecting
From time to time, when watching the GUI, a sensor may fail to report what you feel should
have been a detection. There are multiple reasons for this:
• Multiple detections squashed one of the detection displays at the Operator
Terminal/GUI. (typically a track will form even if the display doesn’t show).
•
Gateway light does not appear to be on
• Reposition gateway out of the sunlight.
• Check to see if battery is plugged in.
Nodes shut off by themselves (pre-production units only)
There are instances where the nodes have shut themselves off. The most common causes are:
• The unit was not turned on (easy to do in a hurry)
