Bluetooth The AWT420 features a fully certified Bluetooth® 4.2 Low Energy module. This allows users wireless
communication with the transmitter using the dedicated CWA mobile application.
The mobile application is available for both Android™ and iOS™ operating systems.
Note. Only mobile devices with support for Bluetooth® 4.2 or newer are compatible.
Device Enable
Enables or disables power to the Bluetooth module. When disabled the module is no longer advertising
and is not connectable.
Device Name Read only device name. This device name forms part of the advertising data used by the module allowing
the user to differentiate between other Bluetooth devices within range when scanning for devices to
connect to.
This Bluetooth Device Name is generated automatically from the instrument tag. Therefore, whenever
the transmitters instrument tag is changed the Bluetooth Device Name changes to reflect it.
Pairing PIN
The fixed 6-digit PIN number used when pairing the transmitter and mobile device. Once paired the PIN
number is no longer required when re-connecting as the bonding information is stored within the module.
Generate New PIN Allows the operator to generate a new pairing PIN. The new pairing pin number is generated randomly by
the transmitter.
Communication level menus for Modbus, Profibus, HART, Ethernet are enabled only if an optional
communications module is fitted.
Refer to the communications supplementary manuals for full details of MODBUS, Profibus, HART
and Ethernet connections and configuration together with tables detailing Profibus slot/indexes
and MODBUS coils and registers:
