Configuring RFD s After the FFD Discovery and Configuration process has been completed navigate back to the Configure Devices link As previously suggested all RFD s would not have been powered up during the FFD Discovery and Configuration process There are two reasons for this First since all the RFD s are battery powered devices and can only communicate with the FFD s and not directly with the PAN Coordinator if you were to install the batteries in the RFD s after 192 Seconds the RFD s start searching for the FFD mesh nodes which without the PAN Coordinator would not be able to construct the mesh and thereby place the RFD s into network alignment In short the batteries which should normally last for between 2 to 4 years would deplete within 36 hours without the mesh network established Second from a device management standpoint it is a cleaner more discernable Device List that the Integrator will have at the conclusion of the process At this point Start Discovery a second time and leave it on until the following two actions are completed Go to the location of each installed RFD and install the batteries in the device While the chassis of the device is separated before you re attach it Push and Release the white Bind button on the back of the circuit board and mount the RFD in its final position The RFD will associate from a mesh architecture standpoint with the best available FFD
