Replacing a WCI on a Network

See

Moving a WCI From One Device to Another

Any time a WCI is moved from one UC to another or from a UC to a repeater, or from a repeater to a
UC, the WCI should be cleared first. Before moving the WCI, set both the GRP and NET rotary
addresses to 0,0 while the WCI is powered. Wait about 10 seconds for all the LEDs to flash
simultaneously. This will clear any UC and network information from the WCI and allow the WCI take on
a new identity.
Changing the ZigBee® Channel of the Wireless Network
If interference is suspected on an established network, the ZigBee
be changed. This change is possible without having to physically change the rotary address switches on
each WCI in the network. This is done in Tracer TU under Wireless >Advanced. For information on how
to do this please see the Help topic in Tracer TU titled "Changing the Channel of a Wireless Network".
Please note that most of the time interference is not the cause of poor network performance. What
appears to be symptoms of interference is more often a network layout issue. It is highly recommended
before changing the network channel, to inspect the network layout to make sure the coordinators are
centrally located, there are no obstructions that could block the radio signal, and the WCIs are all within
design limit range.

Closing the Network

To prevent WCIs from joining an open network (indicated by an illuminated OPEN_NET LED), you can
close the network by using Tracer TU or the coordinator WCI.
Using Tracer TU
After attaching Tracer TU to a wireless device, select Close Network from the Wireless menu.
Using a WCI
To close an open network (indicated by an illuminated OPEN NET LED) so that other WCIs cannot join,
push the OPEN NET button on the network coordinator WCI. (Pushing the OPEN NET button on an
open member WCI closes just that one WCI.)

Disbanding a Network

Some rare circumstances may require disbanding the network.
Using Tracer TU
After attaching Tracer TU to the network coordinator, select Disband Network from the Wireless menu.
As the network disbands, the NWK LEDs on all WCIs on the network respond by turning Off.
Using a WCI
Press the START button (for approximately 10-15 seconds) on the coordinator WCI until the yellow
CRD LED and the green NWK LED turn Off. As the network disbands, the NWK LEDs on all WCIs on
the network respond by turning Off.
