Join Device to Network allows you to enter the Network ID (up to 5‐digits) and the Join Key (4 sets of 8 hexadecimal
digits). The Join Key is used for encrypting the data on the wireless network. The Network ID and the Join Key are the
same for all devices connected to a gateway.

The Network ID is shipped with a default value of 1229 and the Join Key with a default value of all zeros. These must be changed
prior to use.
When the gateway is configured in an advanced security mode each device is required to have an individual join key.
