Troubleshooting.
It is possible that the ZigBee® wireless nodes will fail to communicate if they are in too close a proximity to each other.
If you are trying a lab test before you fully commission on site, as is recommended, then make sure the distance
between the Z-2400 wireless nodes is at least one metre.
1.
Check the Output wireless node is powered up and PWR LED is lit.
2.
Check the Output node network status LEDs are toggling 1, 2 then 2, 1.
3.
If you are using a wireless Repeater, check the node is powered up and PWR LED is lit.
4.
Check the repeater node network status LEDs are toggling 1, 2 then 2, 1. If these LEDs flash 1 & 2 at the same
time it means the Repeater cannot connect to the Mesh either because:
a) The Output node is not powered up.
b) The ZigBee signal strength is too weak to connect (also check the Signal Quality LEDs).
c) A wrong Mesh ID has been programmed into the node.
5.
Check the input wireless node is powered up and PWR led is lit.
6.
Check the Input node network status LEDs are toggling 1, 2 then 2, 1. If these LEDs flash 1 & 2 at the same time it
means the Input node cannot connect to the Mesh either because:
a) The Base node is not powered up.
b) The ZigBee signal strength is too weak to connect.
c) A wrong dip switch has been set.
7.
After the power supply of the Output and Input nodes have been switched on, the Input node may take up to 1
minute to re-establish a wireless connection.
If you are using the uP Configure software and an error message comes up: 'No devices were discovered'.
1.
Close uP Configure completely, unplug the XU-USB from your PCs USB port, and turn the power supply off to the
Z-2400-A2 node.
2.
Connect up the Z-2400-A2 node again as per the instructions on page 8, re-run the uP Configure software from the
icon on your desktop, and try to connect again.
Considerations & Limitations for Z-2400 Network Systems.
The ZigBee® system does not offer 100% connectivity, even when all the precautions are taken into account no one can
guarantee a good link, as there are many factors that cause problems. With the Z-2400-A2 Series, additional repeaters
can be used in between the Input and Output wireless nodes (particularly good when transmitting through solid walls).
Instead of, or in addition to the use of repeaters, higher gain antennas can be used to extend the wireless range further.
