2.2 Creating the F-Link network

The F-Link network must be created on site by 'joining' all F-Link Nodes to the Master.

2.2.1 Node addressing

Each F-Link must have a unique address for the system to operate. One F-Link must be set as the Master
(address 0) and the other F-Links set as Nodes (addresses 1-15). The Node addresses do not need to be
consecutive, but they must be unique.
Use the DIP switches on the circuit board inside each F-Link to select the required address. If powered, the F-
Link will detect the change and reboot.

2.2.2 Preparing to join

Once the frequency channel has been chosen and set (see page 5) and all units are correctly addressed as
above, the site network can be created. Firstly, connect antenna(s) and power to all remaining F-Link unit(s).
Never operate an F-Link without a suitable antenna connected.
The Master F-Link will display NOT JOINED TO ANY NODE and on factory-default systems will be named "Main
Building"). The Node F-Links will display NOT JOINED TO A MASTER.
You can still join the F-Links to the network and make changes to the configuration after the units have been
installed. However having all the F-Links together in one place whilst you do this makes the process much
easier. It allows any issues to be dealt with quickly and simply – without the need to repeatedly walk back
and forth across the site. The network settings (and any other configuration changes) are stored in non-
volatile memory and retained even when the power is disconnected, so any changes made will still be there
once the units have been installed in their final locations.

2.2.3 Network join procedure

1. Put the system into network join mode
Press and hold the 'join' switch on the Master
F-Link until it displays LISTENING FOR NODES
2. Join each Node to the network
Press and hold the 'join' switch on any one
Node until it displays JOINING NETWORK.
CONTACT MASTER. Once joined, it will
display SUCCESSFULLY JOINED NETWORK
and then reset.
Repeat step 2 for each Node in turn.
Any un-joined Nodes will continue to display
NOT JOINED TO A MASTER.
3. Exit network join mode
Press and hold the 'join' switch on the Master
until it displays STOPPING JOIN IN 5S.
The Master will then display LISTENING ENDED NOW HAVE {NN} NODES. Make sure the number of Nodes
shown is correct.
If not manually stopped, network join mode will automatically exit after 30 minutes.
