Q: Nothing happens when I click on the Data Logging button, what could be wrong?
A: The Java policy file is not setup properly. Make sure you get a Java policy file and copy it to a folder in the host computer. Then input the java runtime argument in Java Setup (Control Panel) with the appropriate path to the policy file. Close all web browser and
Q: The Chart trend line for all the variables are broken, what could be wrong?
A: It indicates that a TCP connection to the Coordinator was
Q: The trend line for one of my sensors inside one End Device is broken, what could be wrong?
A: It indicates that TCP connection to the Coordinator is good but the Coordinator did not have any readings from the corresponding End Device. Make sure End Device is still blinking according to the update rate. It could be caused by a reset/power cycling of the Coordinator as well.
Q: Nothing happens when I click on the Save Current Graph button, what could be wrong?
A: The Java policy file is not setup properly. Make sure you get a Java policy file and copy it to a folder in the host computer. Then input the java runtime argument in Java Setup (Control Panel) with the appropriate path to the policy file. Close all web browser and
Q: Nothing is shown inside the Diagnostic page/applet, what could be wrong?
A: The first thing you want to try is to click your mouse right inside the box. Then minimize and restore the web browser. Try to move the scrollbar as well. If nothing works after about a minute, check the TCP connection to the Coordinator.
Q: The End Device repeatedly makes 4 blinks every 2 seconds and then goes off for 3 minutes, what does this mean?
A: It is equivalent to getting a “Lost” message in the Java applets. It means that the End Device found the Coordinator when it was powered on, but it cannot communicate with it currently. Make sure the Coordinator and the End Device have the same Network ID (NID). Also, make sure the Coordinator is powered on, the IEEE802.15.4 communication channel is unchanged, the first DIP switch (of the
Q: While the End Device is up and running I notice a sequence of blinking patterns that seem to repeat themselves, what could be wrong?
A: It means that the End Device needs several retransmissions before getting an acknowledgement packet back from the Coordinator. This indicates a reduced performance since more retransmissions required. Retransmissions consume power and cause shorter battery lifetime. Adjust the antenna and relocate the End Device for better communications. See Section 5 for more details.
