■ Connecting with a personal computer
This unit can be remotely controlled from a PC equipped with a RS-232C connection. It is also possible to input com-
ments from a PC for recording comment information along with the video.
♦Connection via modem
Please use RS-232C Straight cable (9pin) to connect a modem to this unit. The setting of CTS should be set to “HIGH”
or “ON”. Please refer to the instruction manual of a modem for details about connection.

■ RS-232C settings
Communication related settings of this unit are made in “MODE”and “SETTINGS”of the <RS-232C> screen. Set the
settings to the same values as the connecting modem or PC.
When controlling this unit remotely from a PC, set “MODE”in the <RS-232C> screen to “REMOTE A”, “RE-
MOTE B”, or “REMOTE C”.
“REMOTE A”: State information is returned from the unit.
“REMOTE B”: State transition information is returned from the unit.
“REMOTE C”: State information is not returned from the unit.

■ Command code system
2 types of command codes of “direct operation specification”and “false operation panel”can be selected according to
the purpose of the unit.
■ Description of command code system
♦Direct operation specification
This system is used to control or set the unit and comfirm the execution or error of the command sent from the PC by the
status returned from the unit. 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 sent from the PC to the unit for each operation such as power on/off, recording,
playback, etc.
Menu setting type commands are used to specify 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 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 the status is changed.)
Indicates POWER ON command has been sent.
Indicates that the unit has received a command.
EX : Indicates that a command has been executed.
00 : Indicates that the execution was successful.
PW1 : Indicates response to POWER ON command.
03 : Indicates POWER ON status.
Example) Turning ON the unit.

When the unit cannot execute the operation setting type command or menu setting type command which is
sent from a PC, the content of that error 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 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 transition of the actual execution.

♦False operation panel command type
This system is used to specify operations of this unit from a PC as if operating the actual operation button of the remote
control while viewing the output video. Each command corresponds to the operation button of the remote control.
• Input confirmation type
Send commands as if operate the buttons of the remote control. 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. After sending
a command, the command execution result, error type, and command name can be checked by the status returned from
the unit. To check the actual execution, view the output screen of the unit on the monitor screen.
Indicates that a command equivalent to “press the POWER button”was sent.
Indicates that the unit has received a command.
EX : Indicates that a command has been executed.
00 : Indicates that the execution was successful.
KKP0 : Indicates that the POWER button was operated.
Indicates that a command equivalent to “press the PLAY button”was sent.
Indicates that the unit has received a command.
EX : Indicates that a command has been executed.
00 : Indicates that the execution was successful.
KKB1 : Indicates that the PLAY button was operated.
Indicates that a command equivalent to “press the PAUSE button”was sent.
Indicates that the unit has received a command.
EX : Indicates that a command has been executed.
00 : Indicates that the execution was successful.
KKB4 : Indicates that the PAUSE button was operated.

For control type 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 transition of the actual execution.
♦State transition information function
EX : Indicates that a command has been executed.
AA : Indicates the state transition information.
0103 : Indicates that status condition of POWER ON.
Example) Issuing state transition information of system mode "POWER ON".

When setting “MODE”in the <RS-232C> screen to “REMOTEA”, every state information is returned from the unit. When
setting to “REMOTE B”, state transition information is returned from the unit. When setting to “REMOTE C”, state
information is not returned from the unit.
♦Command receive confirmation function
After executing a received command, the error type during command execution is notified after execution status “EX”.
