Cautionary note on sending commands
After sending the command, make sure to check the operation of the recorder or the response such as an error before
sending the next command. Some commands such as search and copy take time to respond, therefore, test the
command operation suffi ciently before the actual operation.
RS-232C settings
Settings related to communication of this recorder are made in the <Setup Menu> <Communication setting> <RS-
232C setting>. Make the same settings as the PC connected.
When remotely controlling this recorder from a PC, set “RS-232C operation” in the <RS-232C setting> to “Remote
A,” “Remote B,” or “Remote C.”
“Remote A” : The recorder returns all types of operation status notifi cation.
“Remote B” : The recorder only responses to the command codes.
“Remote C” : The recorder does not return any notifi cation.

Command code system
2 types of command codes of [direct operation specifi cation] and [quasi-front panel operation] can be selected according
to the purpose of the recorder operation.
Description of command code systems
Direct operation specifi cation
This system controls or sets the recorder by confi rming the status from the recorder such as execution and error which
are 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 com-
mands” which checks the operational status of the recorder.
• Input format
In case of “operation setting commands” and “status check commands,” send the command to the recorder for each op-
eration such as power on/off, record, playback, etc.
In case of “menu setting commands,” specify the setting item for each menu setting of the recorder.
As a general rule, do not send commands continuously, but send the next command after checking that the present com-
mand has been executed and completed.
• Response format
After sending a command, the following items can be checked by the status returned from the recorder.
1) Command execution result, error type, command name, and operation status.
2) For operation setting commands, the operational mode of the recorder can be distinguished by the mode number
of the returned status.
Distinction cannot be made for menu setting type commands. (Mode number is notifi ed only when the status is
changed.)
Example) Turning on the power of the Recorder.

Meaning
PW1
≤
Indicates POWER ON command has been sent.
RC
≥
Indicates that the recorder has received a command.
EX,00PW1,10
≥
EX : Indicates that a command has been executed.
00
: Indicates that the execution was successful. (Error type)
PW1 : Indicates response to POWER ON command.
10
: Indicates POWER ON status.
When the recorder 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 recorder. Check the error code and take
appropriate measures.
For operation setting commands such as recording and playback, the actual operation (command execution) may
take some time after transmitting the command. 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.
