LRP75 Long Range Passive Reader/Writer 25
EXAMPLE
Writes 4 bytes of data to the tag starting at address 0001H. A timeout
of 2 seconds (07D0H = 2000 x 1 msec increments) is set for the
completion of the Block Write.
5.6.4 Command 7 (07H): Read Tag Serial Number
DESCRIPTION
This command retrieves the 8-byte tag serial number.
DISCUSSION
Each LRP tag has a unique serial number. This number can not be
changed and is not part of the 48 available data bytes. The tag serial
number will be returned in the LSB only with the MSB as 00H. The
timeout value is given in 1 msec increments and can have a value of
1EH to FFFEH.
