[Sample of status reply ]
When [DC2]PK is received using a tag with 04123456789ABC of UID.
■Write successful (UID read successful)
[STX]23,1,N,UD:04123456789ABC[CR][LF][ETX]
■Write successful(UID read fail)
[STX]9,1,D,UD:[CR][LF][ETX]
■Write fail (UID read failed)
[STX]9,0,D,UD:[CR][LF][ETX]
[Supplemental explanation]
1.The write status and UID is returned when [DC2]PK is received after RFID write.
2.Although write is successful status will be returned without data if you fail to read UID since UID read will be done
separately from write.
3.Write a code; a case without the printing, the return data "Write result status" "0 :Write fail"; "Error symbol" "A :All
errors".
4.For details on the return sequence, refer to 16.12 ESC+RU UID return(ISO/IEC14443 TypeA).
