The recorder can work with various applications through the use of commands.
The communication that is achieved through commands is referred to as "general
communication."
The following types of commands are available. The first character of command names
represents the command type. For example, in the command "SRangeAI," "S" represents
the command type. The second and subsequent characters represent the contents of
commands.

A single command consists of a command name, parameters, delimiters, and terminator.
The command name is written in the beginning, and parameters follow. Delimiters are used
to separate the command name from parameters and between each parameter. A delimiter
is a symbol that indicates a separation. A terminator is attached to the end of a command.
Command name,parameter 1,parameter 2 terminator
Example of a Command
SRangeAI,0001,VOLT,2V,OFF,-15000,18000,0
You can send multiple setting commands in a series. When writing a series of commands,
separate each command with a sub delimiter. A sub delimiter is a symbol that indicates a
separation. A terminator is attached to the end of the series. The maximum number of bytes
that can be sent at once is 8000 bytes (8000 characters).
