Direct Mode - Generic Read/Write Interface
This interface allows the Host Application to send generic commands for RFID operations. These
commands consist of simple read and write operations requiring no knowledge (except data format) of the
tag types being used. They utilize the printer's database for specific parameters.

within read/write distance of the RFID programming device otherwise a fault will occur and a warning
message will be displayed.
