2.3.1.8 Slow Write A Byte
Function: to write data into the appointed address unit of appointed tag.
Length of written data takes byte as unit, and 4bytes can be written in at
most once. Writable byte address for user is 8~223.
Command code: F2H
Command parameter: 8 bytes ID(subject to the sequence of tag ID
number); 1byte start address(aa), value 8~223; 1byte length of block(nn),
value 1~4; nn bytes written data.
Command packet: 『40H 12+nn F2H id aa nn xx --- xx
CheckSum』
Return packet: if success, return data is null.
『F0H 02H F2H 1CH』
Note: the command writes data into tag byte by byte, slow in speed.
Only used for tags not support previous write command.
Command format with reader address:
Command code: F2H
Parameter with reader address: address
Command parameter: 8 bytes ID(subject to the sequence of tag ID
number); 1byte start address(aa), value 8~223; 1byte length of block(nn),
value 1~4; nn bytes written data.
Command packet: 『40H 13+nn F2H address id aa nn xx ---
