Two-Way Paging
The TReX supports two-way paging. The TReX can return responses via serial or TCP
connections. Transmitter capable TReX units can additionally respond at high power across
the air.
Not only can acknowledgements be returned from the TReX, but confirmation of job
acceptance receipts can be returned. This means that messages can be sent to single or
multiple TReX units and clear details can be returned to notify if a message has been read or
an action is being performed.
Applications for this feature include:
•
sending messages to a fleet of vehicles (e.g. ambulance or taxi) for one of many to
respond.
•
use in a muster station type scenario, where in the case of emergency, a warden can
notify when an area is safe or all personnel are present.
Example:
An emergency dispatch system may send a paging message to a group of ambulances for
attendance at an emergency. The message will be displayed on a TReX unit within the
ambulance with prompt to attend if possible. Accepting the job can be performed with a
simple keypress that will send receipt to the dispatch system that the vehicle is on-route.
See WTE Ack and Confirm Protocol for usage details.
With a single keypress, key messages can be responded to. Details of the responder are
returned and logged.
