TReX User Manual v2.14 Firmware

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.
 

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.
