Rfid With Byte Count Specifier - Datamax-ONeil I-Class User Manual

WX / W1X:

RFID with Byte Count Specifier

The upper case X identifies an RFID data string with a string 4-digit length specifier, which
allows values 0x00 through 0xFF to be included within the data strings without conflicting with
the DPL format record terminators. The four-digit decimal data byte count immediately follows
the four-digit column position field. This value includes all of the data following the byte count
field, but does not include itself.

The following example encodes, starting at block 001, "Datamax <CR> writes RFID best." It
includes a Byte Count Specifier (the portion in bold), where 0024 equals a four-digit decimal data
byte count and includes all bytes that follow until the end of the data. Field termination is set by
the byte count.
