In order to communicate with the THUM Adapter, polling must be activated on the Field
Communicator. The default address for the THUM Adapter is 63. Also, note that any
configuration changes must be sent to the transmitter using the Send key (F2).
AMS wireless configurator
AMS is capable of connecting devices directly using a HART modem or the Gateway. For
