Device network configuration

2.5.1

Join device to network

Fast Keys
In order to communicate with the Smart Wireless Gateway, and ultimately the Host System, the
THUM must be configured to communicate over the wireless network. This step is the wireless
equivalent of connecting wires from a transmitter to the host system.

Using a Field Communicator or AMS, enter the Network ID and Join Key so that they match the
Network ID and Join Key of the Smart Wireless Gateway and other devices in the network. If the
Network ID and Join Key are not identical to those set in the Gateway, the THUM will not
communicate with the network. The Network ID and Join Key may be obtained from the Smart
Wireless Gateway on the Setup>Network>Settings page on the web server.
2.5.2

Configure update rate

Fast Keys
The Update Rate is the frequency at which a new measurement is taken and transmitted over
the wireless network. This by default is 1 minute. This may be changed at commissioning, or at
any time via AMS Wireless Configurator. The Update Rate is user selectable from 8 seconds to 60
minutes.
