46 LRP75 Long Range Passive Reader/Writer
The LRP75 remains in Continuous Block Read mode until it receives
a new continuous read command with a zero read length. To stop
Continuous Block Read Mode, issue the Start/Stop Continuous Read
command with a read length of zero (0).
If the LRP75 receives any other command from the host while
performing continuous read, an error (0DH) will be sent to the host.
NOTE:Other commands will NOT be performed when the LRP75 is
performing continuous read.
