3 Description of functions
• When performing data communication in ASCII code
Use device codes by converting them to ASCII code (2 or 4 digits), and send them in the order higher-order byte to
lower-order byte. Use codes in upper case characters for letters of the alphabet.
With subcommands 0003, 0002 and 0001, 0000, the number of digits converted to ASCII code will differ.

*1: Send input relay device codes in order from "X". Note that asterisks (*) from the second character onward may
also be specified with a space (code: 20H).
• When performing data communication in binary code
Use numerical values (1 or 2 bytes), and send data in the order lower-order byte to higher-order byte.
With subcommands 0003, 0002 and 0001, 0000, the data size of the numerical values will differ.
