T24-HR [Handheld Reader Roaming]

Overview
The T24-HR is a roaming handheld that can be used to view the reading supplied by an unlimited number of
acquisition modules. The acquisition Data Tags or IDs do not need to be known beforehand.
The handheld will automatically wake any device on the same channel and encryption key.
An internal list is maintained of the top n number of acquisition modules ordered by signal level and a Next key
on the handheld allows cycling through this list.
The list size (n) is variable between 2 and 20 and this enables the viewing experience to be tailored to particular
applications.
The acquisition modules are identified by their 4 character hexadecimal Data Tags and these may be set using the
T24 Toolkit.
When in communication with a particular acquisition module the LED on that module is activated. This provides
visual feedback of the selected and currently viewed module. The LED output can also appear optionally on the
digital output.
Communications
To configure the device you will use the Read and Write mechanisms described in the Data Packet Structures
section to read and write parameters and execute commands.
