NOTE: In this initial Adv-LX RFID Printer, the Skyetek- M1 Reader/Writer Module limits individual Read or Write transfers to/from the RFID-Tags to 64-bytes maximum. CPL command lines are naturally limited to 256-bytes. Therefore, 4 separate 64-byte WT commands must be executed to fill a 256-byte RFID- Tag,
