28 LRP75 Long Range Passive Reader/Writer
NOTE:Other commands will NOT be performed when the LRP75 is
performing continuous read.
EXAMPLE
The following example reads 8 bytes of data from a tag at address
05H, with a delay between identical reads of 2. After a tag is read, it
must remain out of the RF field for at least 2 seconds before it will be
read again. The LRP75 will send a response confirming its in
Continuous Block Read mode.
Field Description
Header AAH
Command Command number in hex
Start Address The tag address where the read will start
Read Length The number of tag addresses to be read. A 0 length
stops continuous mode.
Delay Between
Identical Reads
Time period that the tag must be out of reading
range before the LRP75 will send the same data to
the host.
