Description
4.4.2 G2WRITEX: Gen2 Write – Extended Addressing
G2WRITEX {addr} {data}
Gen2 USER memory bank write command – extended addressing
:WR_OK:handle
Performs a standard Gen2 write command on the USER memory bank using a 2-byte EBV-formatted
address parameter (note: Gen2 write instructions on the other memory banks are performed with
other CLI commands described later in this section). The G2WRITEX command has 2 parameters:
address (addr) and data (data). The address parameter defines the write instruction starting address
and must be presented as a 4-character, 2 byte EBV-formatted address (refer to APPENDIX B to
convert standard addressing to EBV-formatted addressing); the data parameter defines the 16-bit data
word written to USER memory. The G2WRITEX command may be used to write any unlocked
USER memory location. A successful Gen2 write cycle is indicated by an audible chirp from the
buzzer on the reader as well as a “write OK” status message and the tag’s handle displayed on the
terminal.
NOTE:
Parameter
addr
data
1. Once the address and data parameters have been entered in an instruction, subsequent write
2. The data parameter is expressed as a hexadecimal value up to 4 characters in length. For
instructions may be repeated without re-entering the parameters – entering the command on
its own will produce the same result. In addition, a subsequent write instruction may only
define the address – the previously defined data parameter will continue to be used.
example, the value x000B may be expressed as xB, x0B, x00B, or x000B.
