49 LRP2000 Passive Reader/Writer
5.2.3 Set Operating Mode
The “[3] Set Operating Mode” menu allows you to choose the ABx command protocol the LRP2000 uses,
or configures it to enter Continuous Read Mode automatically upon start-up.
*** Set Operating Mode ***

information).

Operating Mode
The LRP2000 offers three modes for the transfer of data and commands. ABx Standard (ABxS) uses only
the LSB for tag data, while ABx Fast (ABxF) uses both the MSB and 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.
Framing Editing
If option 1 “ABx Fast” or option 2 “ABx ASCII” is chosen from “Operating Mode” above, you have the option
of modifying the packet header and terminator characters. This can be useful when interfacing with other
Host devices that require the terminator to be a CR “0Dh.” The current preamble and terminator will be
displayed.The default values are 02h 02h as the packet header, and 03h as a single terminating character.
These are the values used in command and response examples throughout this Operator’s Manual, but
can be changed to fit your needs. To use the current message framing, simply answer NO.
Current FAST Packet Framing
Preamble = 02H 02H
Terminator = 03H
Modify FAST packet framing? [0] No [1] Yes
OR
Current ASCII Packet Framing
Preamble = 02H 02H
Terminator = 03H
Modify ASCII packet framing? [0] No [1] Yes
If the YES option is selected the following prompt appears asking whether the packet should have a one-
or two-character header.
Number characters in packet preamble? [1] One [2] Two
If a one-character preamble is desired, you are prompted to enter the hexadecimal value of the character
in the range of 01h to 7Fh. The value 0 is illegal and cannot be used for the mess age preamble.
New FAST Header Character (01 - 7F) =
1. Valid ranges for Start Address and Length depend on the tag category.
