Command Protocol?
The LRP2000 offers three modes for the transfer of data and
commands. ABxStandard (ABxS) uses only the LSB for tag data while
ABx Fast (ABxF) will use both the MSB and the LSB for the passing of
data. ABx ASCII (ABxA)mode permits RFID operations using seven
bit data packets in the form of printable ASCII characters.
Checksum
ABx Fast and ABx ASCII also permits you to include a checksum in
the command. To use a checksum value with the ABx commands, you
must enable the checksum option. It is recommended that you enable
the checksum option.
Power up in Continuous Read Mode
You also have the option of setting the LRP2000 to start-up in
Continuous Read Mode. When you have configured the LRP2000 to
function in this manner,you do not issue commands to the LRP2000. It
will, upon start-up, enter directly into a Continuous Read Mode. Since
this bypasses the normal command parameters, you must specify the
Continuous Read Mode parameters. The LRP2000 will respond to
other commands and resume Continuous Read Mode when
completed. If you are using your LRP2000 in this mode, you must
choose if you want the LRP2000 to read a single tag or read multiple
tags within the field. To exit Continuous Read Mode you must either
re-enter the configuration menu and select NO from the Power up in
Continuous Read Mode option, or issue a Continuous Read command
from the host with a read length of 0 as described in Chapter 6, RFID
Interface.
Start Address (0 to 111)
Enter the tag address where you want the read to begin.
Length (1 to 112) 112
Enter the length of the read you wish the LRP2000 to perform. Make
certain that the length value does not exceed the number of possible
addresses following the starting tag address. Entering a read length of
0 will disable Continuous Read Mode.
