Configuration
2.3 Device sensor configuration
The THUM Adapter, attached to a powered sub-device, receives HART communication from a
handheld Field Communicator or AMS
™
Device Manager.
Field Communicator
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 Wireless Configurator is capable of connecting devices directly using a HART modem or
the Gateway. For configuring through AMS Wireless Configurator, double click the device icon
and choose the Configure/Setup tab. AMS Wireless Configurator configuration changes are
implemented when the Apply button is selected.
2.4 Connection diagrams
Bench hook-up
Connect the bench equipment as shown in either Figure 2-1 or Figure 2-2, and turn on the Field
Communicator by pressing the ON/OFF key or log into AMS Device Manager. The or AMS Device
Manager will search for a HART-compatible device and indicate when the connection is made. If
the or AMS Device Manager fail to connect, it indicates that no device was found. If this occurs,
refer to Section 4: Commissioning.
Field hook-up
Section 2: Configuration details the field hook-up requirements in Figure 2-1 and Figure 2-2.
