In the Command code area of the command data, whether the Reader/Writer reads or writes data as
ASCII code (or JIS8 code) or HEX code numeric data is specified.
Name Code Description
ASCII Code A A character of data occupies 1 byte (1 address) on a Tag as an
ASCII code or a JIS 8 code.
Control codes 02 (STX) and 03 (ETX) cannot be used.
HEX code H A character is handled as hexadecimal data. Therefore, only
characters from 0 to F are accepted. Two characters of data
occupy 1 byte (1 address) on a Tag.

When writing "V720" to four bytes of memory of page 00 using ASCII data, the data will occupy the
Tag's memory as follows:
byte 0 byte 1 byte 2 byte 3

    V  7   2    0
• Example of Hexadecimal Representation
When writing "12345678" to four bytes of memory of page 01h using hexadecimal data, the data will
occupy the Tag's memory as follows:
byte 0 byte 1 byte 2 byte 3
