Synchronizing AMS Trex data with AMS Device
Manager
AMS Trex provides the ability to connect to AMS Device Manager and update the AMS
Device Manager database with device data. The initial operation that enables this is a
pairing of an AMS Trex unit with a single AMS Device Manager station.
By default, synchronization happens automatically when AMS Trex is connected to a
paired AMS Device Manager station using USB, or when it is connected to a Wi-Fi network
that can communicate with an AMS Device Manager Server Plus. Synchronization occurs
when the devices match in both systems (by manufacturer, device type, device revision,
and protocol version).
Note
AMS Trex cannot communicate wirelessly with an AMS Device Manager system whose
ServerPlus name is not a valid hostname (for example, named with an IP address).
In the AMS Device Manager Sync screen in Settings, AMS Trex shows:
• The name of the AMS Device Manager station to which the unit is paired, along with an
option to unpair. A Trex unit can only be paired with one AMS Device Manager system
at a time.
• An indication of whether data is pending to be synchronized to AMS Device Manager
• The time of the last synchronization
After a Trex unit has been paired to an AMS Device Manager system, synchronization
happens automatically when:
• A Trex unit is connected to the AMS Device Manager station by USB OR
• A Trex unit wireless radio is on, and is connected to a wireless access point
Note
AMS Device Manager will synchronize with as many paired AMS Trex units as are
connected to wireless, and in-range. An Audit Trail entry indicates each pairing, unpairing,
and synchronization with a specific Trex unit.
