Product Usage Instructions

• Connecting the Monitor to a Computer:
  • Use an RS-232 cross cable to connect the computer’s COM port to the RS-232C input terminal on the monitor.
• Communication Procedure:
  • Commands sent from the computer to the monitor will trigger operations on the monitor and a response message will be sent back to the computer.
• Command Format:
  • Commands consist of a command field and a parameter field.
  • Ensure the parameter field contains 4 characters made up of alphanumerical characters (0-9, +, -, space, ?).
  • Example: VOLM0030 (VOLM as command field, 30 as parameter field).
• Response Codes:
  • If a command is executed correctly, the return code will be ‘OK’.
  • If a command fails, the return code will be ‘ERR’.
  • If a command is taking time to execute, ‘WAIT’ will be returned. Do not send any commands during this period.
• FAQ:
  • How do I control the monitor using a computer?
  • To control the monitor via a computer, use an RS-232 cross cable to connect the computer’s COM port to the RS-232C input terminal on the monitor. Send commands with the appropriate format and parameters to trigger monitor operations.
  • What is the response code format for commands?
  • If a command is executed correctly, the return code will be ‘OK’. If there is an error in command execution, the return code will be ‘ERR’. If a command is taking time to execute, ‘WAIT’ will be returned.

Controlling the Monitor

Controlling the Monitor with a computer (RS-232C)

• You can control this monitor from a computer via RS-232C (COM port) on the computer.
• This is the description when “Control Terminal” is set to “RS-232C” and “Command Format” is set to “S-Format”.

Computer connection

Connect with the RS-232 cross cable between the computer’s COM port (RS-232C connector) and the RS-232C input terminal on the monitor.

Communication conditions

Set the RS-232C communication settings on the computer to match the monitor’s communication settings as follows:

Communication procedure

Command format

When a command is sent from the computer to the monitor, the monitor operates according to the received command and sends a response message to the computer.

Example: VOLM0030 VOLM 30

• Be sure to input 4 characters for the parameter. Pad with spaces (“ ”) if necessary. (“ ” is a return code (0DH, 0AH or 0DH))
  • Wrong: VOLM 30
  • Right: VOLM 30

If a command has “R” listed for “Direction” in the “RS-232C command table” on page 4, the current value can be returned by using “?” as the parameter.

Example:

• VOLM???? From computer to monitor (How much is the current volume setting?).
• 30 From monitor to computer (Current volume setting: 30).

Response code format

• When a command has been executed correctly
  • A response is returned after a command is executed.
• When a command has not been executed

TIPS

• “ERR” is returned when there is no relevant command or when the command cannot be used in the current state of the monitor.
• If communication has not been established for reasons such as a bad connection between the computer and monitor, nothing is returned (not even ERR).
• “ERR” may be returned when a command cannot be received correctly due to interference from the surrounding environment. Please ensure that the system or software resends the command if this occurs.

If execution of the command is taking some time

• Some commands return “WAIT”. In this case, a value will be returned if you wait a while. Do not send any commands during this period.

Communication interval

• After “OK” or “ERR” is returned, you can send the following commands.
• To set a timeout for the command response, specify 10 seconds or longer.
• Provide an interval of 100 ms or more between the command response and the transmission of the next command.

TIPS

• When “ALL RESET” is executed, this monitor will restart. Wait at least 1 minute before sending the next command.
• Before sending a power “On” or “Off” command, it is recommended that you perform buffer clear at the sending application side.
• After executing a power “On” or “Off” command, wait at least 1 minute before sending the next command.

Command Table

RS-232C command table

How to read the command table

• Command: Command field (See page 2.)
• Direction: W When the “Parameter” is set in the parameter field (see page 2), the command functions as described under “Control/Response Contents”. R The returned value indicated under “Reply” can be obtained by setting “????” in the parameter field. (See page 2.)
• Parameter: Parameter field (See page 2.) Reply: Response (Returned value)
• *: “ ”: It cannot be used in a standby state or input signal waiting for state when “Control Terminal” is set to “RS-232C” or “Power Save Settings – Mode” is set to “Low Power”.
• “–”: Indicates a command which can be used when the power is on.

Controlling the Monitor with a computer (LAN)

• Your monitor can be connected to a LAN allowing you to control it from a computer on the LAN.
• This is the description when “Control Terminal” is set to “LAN” and “Command Format” is set to “S-Format”.

TIPS

• This monitor must be connected to a network.
• Set “Monitor Control via Network” to one in “Monitor Control” on the Network menu.
• When “Power Save Settings – Mode“ is set to “Low Power”, the control is disabled in the standby state or input signal waiting state.

Command-based control

You can control the monitor using RS-232C commands (see page 4) via terminal software and other appropriate applications. Read the manual for the terminal software for detailed instructions.

1. Connect the computer to the monitor.
2. Specify the IP address and data port number (Default setting: 10008) and connect the computer to the monitor.

  * When the connection has been established successfully, [Login: ****] is returned as a response.
2.  **Send the user name.**
  * Send [user name] + [ ****].
  * If the user name is not set, send [ ****].
  * When the transmission is successful, [Password: ****] is returned as a response.
3.  **Send the password.**
  * Send [password] + [ ****].
  * If the password is not set, send [ ****].
  * When the transmission is successful, [OK ****] is returned as a response.

2. Send commands to control the monitor.
   • The commands used are the same as those for RS- 232C. Refer to the communication procedure (see page 2) for operation.
   • Usable commands are provided in the RS-232C command table (see page 4).
3. Disconnect the connection with the monitor and quit the function.
4. Send [BYE ].

  * When the transmission is successful, [Goodbye ****] is returned and the connection is disconnected.

TIPS

• Connection is automatically disconnected when the time specified in “Auto Logout Time” elapses over a no-communication period.
