Data Code Designation
Data to be read or written is specified in the command to be handled as either ASCII (JIS8 unit code)
character data or as hexadecimal numerical data.
• ASCII (JIS8 Unit Code) Designation
Each data character is allocated 1 byte (1 address) of Tag memory
and stored as ASCII or JIS8 unit code.

• Hexadecimal Code Designation
Characters are handled as hexadecimal data. Therefore, only
characters 0 to F can be received. Each two characters of data is
stored as is in 1 byte (1 address) of Tag memory. Therefore, always
set two-character units (even number of characters) for write
commands.
One byte of Tag data is converted to two hexadecimal characters
(00 to FF) and transmitted. A command error will occur if an odd
number of characters is mistakenly set.
