Multi-Reader/Writer Operation
There are two modes that you can use for multi-Reader/Writer operation: Field Extension Mode and
High-speed Traveling Mode.
You can link up to eight Reader/Writers to perform communications operations with RF Tags. One of
the Reader/Writers operates as the master and the other Reader/Writers operate as slaves.
The host device just has to control one Reader/Writer, the master, to easily achieve complex control
operations for all of the linked Reader/Writers.
