Data Code Designation
Data to be read or written is specified in the command to be handled as either ASCII (JIS8 code) char-
acter data or as hexadecimal data.
 ASCII (JIS8 Code) Designation
• Each data character is allocated 1 byte (1 address) of Tag mem-
ory and stored as ASCII (JIS8 code).
 Hexadecimal Designation
• Each character is 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 (i.e., an
even number of characters) for write commands. A command
error will occur if an odd number of characters is mistakenly set.
