Please refer to Protocol Document “721_727H Protocol_EN.pdf” and use Command 20H “Write EEPROM” to write data to 321W

Find out Command for Global Free Cards is on 24*, Bit5 ; then check Memory Layout list to get Memory Location 16H where will store the data

Use Tools Commview to send data; Command Structure Meaning for each byte as below:

7E 08 01 20 00 16 01 20 E9 41

7E mean Head

08: Length

01: How many byte data will be written to Memory
