3.1 Summary
A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters, followed by
parameters (one-byte numbers). For some commands, multiple parameter values can be specified or
parameters are not necessary. Processing is executed by sending a delimiter at the end of the command.
Example: @SPM,2
“,”( a comma, “2C” in hex) is indicated between a command and parameter and between two parameters.
“ ” is indicated as a delimiter CR LF (line feed, “0D” and “0A” in hex).
An error command is returned if an undefined command or wrong parameter is included.
Example: @SSW,1
@ERR,1
If only delimiter is sent, command list as the help command is returned.
Example:
-------------- HELP (1/10) -------------
(CHANNEL SELECT Command)
@GSW / @SSW Getting/Setting Switching channels
@GOF / @SOF Getting/Setting Automatic input channel switching
