Modifying an Air-Fi® Network
This section describes how to modify an established Air-Fi network. Most modifications can be made by
using either the Tracer® TU service tool or the WCI.
To use Tracer TU, you must establish communication with a wireless network and attach to a wireless
device. For instructions, see

Adding WCIs to an Existing Network Using Tracer TU

1. After attaching Tracer TU to a wireless device, select Open Network from the Wireless menu.
2. Observe the green NWK LED illuminate on a WCI that joins the network.

Adding WCIs to an Existing Network Using a WCI

1. Press the OPEN_NET button on the network coordinator WCI to open the network for joining for one
2. Observe the green NWK LED illuminate on a WCI that joins the network.

Adding Coordinators to a Tracer SC+

A Tracer SC+ can have a total of eight WCIs installed on it. Each WCI installed on a Tracer 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. Address the new WCI(s) according to the scheme explained in
2. Install the WCI(s) on the Tracer SC+ as described in "WCI Installation". Use a daisy-chain
3. Use the Tracer SC+ UI/Synchrony to enable the proper wireless networks.
4. A new network will be created for each newly installed WCI, with each WCI as coordinator of the
5. Start Tracer SC+ Device discovery. (Refer to Tracer SC+ Online Help for the discovery procedure.)

Removing a WCI from a Network

If the other WCIs that were members of the disbanded network find an open network within radio range,
they will try to join that network. To prevent that from occurring, you can remove WCIs from the network
until the coordinator WCI is replaced.
Using Tracer TU
After attaching Tracer TU to a wireless device, select Remove from Network from the Wireless menu.
Using the WCI
To remove a member (non-coordinator) WCI from a network, do either of the following:
•
•
After the WCI is dropped from the network, the equipment managed by the associated unit controller is
under the direct, local control of the unit controller.

newly created network. Allow sufficient time for all member WCIs to join the new network.
Devices that previously existed on the wireless network do not need to be rediscovered.
A WCI has to be a network member before Tracer SC+ can discover the controller associated with
the WCI. Tracer SC+ does not discover repeater WCIs.
Press the WCI START button (10–15 seconds) until the green NWK LED turns off.
Note: The same action performed on the coordinator WCI will disband the network.
Change the rotary address on the WCI.
