The command is formatted as follows.
Field Remarks
Command Command number in hex preceded by AAH
Start Address 2 byte value for the start address in the tag
Read Length 2 byte value for the block read length
Delay Between
Identical Decodes
Time the tag must be out of the antenna range before the LRP830 will
transmit data again from that tag. Value is expressed in 1 second units.
Message Terminator FFFFH
EXAMPLE
This example places the LRP830 in Continuous Block Read mode and reads
8 bytes of data from the tag starting at address 0001H. A delay between
identical reads of 2 seconds (0002H = 2 x 1 second increments) is set.
The LRP830 will first return an acknowledgment of the command followed
by a response containing read data when a tag enters the antenna field.
