Controller No.
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.
