Hexadecimal code designation "H"
1 byte of data of tag is converted into two hexadecimal numbers ("00" to "FF") and those numbers are transmitted. Transmitted two
characters are equal to 1 byte of data in a tag. Be sure to specify written data in two hexadecimal numbers from "00" to "FF" (even).
If any odd number data is specified, a command error occurs.
<Example of writing>
