Configuring the device network

Field Communicator
To communicate with the Gateway, and ultimately the information system, the transmitter must be
configured to communicate with the wireless network.
Using a Field Communicator or AMS Wireless Configurator, enter the Network ID and Join Key so they
match the Network ID and Join Key of the Gateway and the other devices in the network. If the Network
ID and Join Key are not identical, the transmitter will not communicate with the network. The Network
ID and Join Key may be obtained from the Gateway on the Setup>Network>Settings page on the web
server. Using a Field Communicator, the Network ID can be configured by entering the Fast Key
Sequence: 2, 2, 1, 1. The Join Key can also be configured using a Field Communicator with the Fast Key
Sequence: 2, 2, 1, 2.
AMS Wireless Configurator
The final device network configuration piece is the Update Rate which, by default, is 1 minute. It can be
changed at commissioning, or at any time, by using AMS Wireless Configurator or the Gateway's web
server. The Update Rate should be between 4 seconds and 60 minutes. To change the Update Rate with a
Field Communicator, use the Fast Key Sequence: 2, 2, 1, 3.
If doing a bench top initial configuration, after completion remove the power module until installation.
When the device is installed, insert he power module and close the housing cover securely. Always
ensure a proper seal so that metal touches metal, but do not over tighten.
