Appendix G Frequently Asked Questions (FAQ)
Q: Java applet is not loaded?
A: Check Java Setting (icon in Control Panel). Make sure cache is disabled and your
web browser is enabled for Java.
Q: I do not see any readings even if the applet is loaded, what could be wrong?
A: 1) Make sure the Coordinator and the End Device have the same Network ID (NID).
2) Check if the battery is still good. You should be able to see the blue LED when you
power the End Device on.
3) If the End Device keeps blinking every second after it is powered on, that means it
cannot find the Coordinator. Try to adjust the antenna and relocate the End Device
according to Section 5.1.
Q: What are the error messages that appear on the "Reading", "Chart", and "Diagnostic"
pages?
Open
A: It means that the End Device cannot detect any of its sensors.
Check the connections for the internal sensor and the external probe if any.
ID
A: It means that there are more than one End Device sharing the same Device ID (DIP
switches #1-5).
Remember, each sensor should have a unique Device ID in the same wireless network.
Turning the device into Identify Mode may help searching for the physical location of
such End Devices. Once the problem is resolved, click on the "Reset Sensor" button
located on the Sensors Parameters page to remove the "ID" error code.
Lost
A: 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, DIP switch #1 (of the 8-DIP switch row) on the Coordinator was ON during
the last Coordinator’s power reset, and there is no obstructive objects blocking the
communications path (see Section 5 for more details). If the obstructive object is only
temporary, you will get the sensor readings once the path is open.
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 re-open the applet again. See Java Setup Section.
