I Description of command code systems
o Direct operation specification
Control and settings are performed by checking execution, errors, etc., from the status returned from the unit for the
command sent from the PC. This command type is structured by operation setting type commands that sets operations
and menu setting type commands that directly sets various menus.
• Input format
Operation setting type commands are to be sent from the PC for each operation such as power on/off, record, playback,
etc., for the unit.
Menu setting type commands are to be specified for each menu setting of the unit.
As a general rule, do not send commands continuously, but send the next command after checking that the present
command has been executed and completed.
• Response format
After sending a command, the following items can be checked from the status returned from the unit.
1) Command execution result, error type, command name, operation status.
2) For operation setting type commands, the operation mode of the unit can be distinguished by the mode number of the
returned status.
Distinction cannot be made with menu setting type commands. (Mode number is notified only when there is change is
status.)
Example) Turn the Unit ON.

When the unit cannot execute the operation setting type command or menu setting command sent from a PC,
the content is displayed in the error type of the status returned from the unit. Check the error code and take
appropriate measures.
For control type commands such as record, playback, etc., the interval between command transmission and
the actual operation (command execution) may take some time. To prevent the gap between operation and actual
execution, read the status after sending the command and check the transition of the actual execution.
