Modifying the Network
This section describes how to modify an established wireless network. Most modifications can be
made by using either theTracerTU service tool or the WCI.
To useTracer TU, you must establish communication with a wireless network and attach to a
wireless device. For instructions, see “Appendix: Using theTracer™TU ServiceTool with Wireless
Networks,” p. 28.
Adding Additional WCIs to an Existing Network
Using TracerTU
1. After attachingTracerTU to a wireless device, select Open Network from the Wireless menu.
Every memberWCI will indicate that the network is open. AnyWCI with a correct rotary address
setting that is located within radio range of a network member, will join the network.
2. Observe the green NWK LED illuminate on a WCI that joins the network.
Using a WCI
1. Press the OPEN_NET button on the network coordinator WCI to open the network for joining
for one hour. Every memberWCI will indicate that the network is open. Any WCI with a correct
rotary address setting that is located within radio range of a network member, will join the
network.
Note: Pressing the OPEN_NET button on a member WCI will open only that one WCI.
2. Observe the green NWK LED illuminate on a WCI that joins the network.
Adding Coordinators to a Tracer SC
ATracer SC can have a total of eightWCIs installed on it. EachWCI installed on aTracer SC becomes
the coordinator of a separate network. If additional coordinator WCIs/networks are needed on a
Tracer SC after the network has been formed, follow these steps.
1. Remove power from theTracer SC. (This will not affect the existing networks.)
2. Address the newWCI(s) according to the scheme explained in “WCI Addressing,” p. 11 , making
sure the addresses do not conflict with existing WCIs.
3. Install the WCI(s) on theTracer SC as described in “Mounting and Wiring the WCI,” p. 13,
Figure 6, p. 15, and Figure 7, p . 15. Use a daisy-chain configuration to install multiple WCIs.
4. A new network will be created for each newly installed WCI, with each WCI as coordinator of
the newly created network. Allow sufficient time for all memberWCIs to join the new network.
5. StartTracer SC Device discovery. (Refer toTracer SC Online Help for the discovery procedure.)
Devices that previously existed on the wireless network do not need to be rediscovered.
AWCI has to be a network member beforeTracer SC can discover the controller associated with
the WCI.Tracer SC does not discover repeater WCIs.
