Command code system

2 types of command codes of [direct operation specification] and [quasi-front panel operation] can be selected according
to the purpose of the unit operation.

Description of command code systems

Direct operation specification

This system controls or sets the unit by confirming the status from the unit such as execution or error which is responded
to the command from the personal computer. This command type is constructed by the "operation setting commands"
which sets operations, "menu setting commands" which directly sets various menus, and "status check commands"
which checks the operational status of the unit.
• Input format
In case of "operation setting commands" and "status check commands," send the command to the unit for each opera-
tion such as power on/off, record, playback, etc.
In case of "menu setting commands," specify the setting item 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 by the status returned from the unit.
1) Command execution result, error type, command name, and operation status.
2) For operation setting commands, the operational mode of the unit can be distinguished by the mode number of
the returned status.
Distinction cannot be made for menu setting type commands. (Mode number is notified only when the status is
changed.)
Example) Turning on the power of the Unit.

When the unit cannot execute the operation setting command or menu setting command sent from a PC, the error
type which shows the content of the error is returned from the unit. Check the error code and take appropriate
measures.
For operation setting commands such as recording, 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 actual operational transition, and then
send the next command.
While displaying the menu screen, you cannot change the menu setting by using menu setting command form.
