Command Format
Specifying Data Code
ASCII (JIS 8 Code)
Hex Code
32
Whether the read or write data is treated as an ASCII (or JIS 8) code or HEX
code is specified in a command.
When the data length is specified to be 7 bits by the DIP switch of the ID Con-
troller, ASCII is specified. When the data length is specified to be 8 bits, the
JIS 8 code is specified.
One character of ASCII or JIS 8 code data occupies 1 byte (1 address) of the
Data Carrier memory.
Example of specifying ASCII code:
W T A 1
Command
Header
ASCII specification
R/W Head No. specification
(fixed to 1)
Data Carrier memory address:
Address
0010
4
0011 4
0012 5
0013 4
0014 4
Note For ASCII (JIS 8 code), refer to Appendix A.
One character is treated as a hexadecimal number. Therefore, only numerals
0 through 9 and A to F can be accepted.
Two characters of data occupy 1 byte (1 address) of the Data Carrier memory.
Therefore, specify data in 2-character units (in even numbers) when using a
write command. If an odd number of data is specified by mistake, an error
occurs.

W T H 1 0
