If command length exceeds 266 characters (for expansion write command):
When the ID Controller receives a command which is not the last frame, it
transmits a delimiter (CR) to the host controller, and is ready to receive the
next command frame.

Specifying Data Code
Whether the read or write data is treated as an ASCII (or JIS 8) code or HEX code
is specified in a command.
ASCII (JIS 8 Code)
When the data length is specified to be 7 bits by the DIP switch of the ID Control-
ler, 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:

Note For ASCII (JIS 8 code), refer to Appendix A.
Hex Code
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 oc-
curs.
