FAQ:

Q: What should I do if a command is taking too long to

execute?

A: If a command is taking some time to execute,
the monitor may return a “WAIT” response. Do not send any
additional commands during this period and wait for a response.

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

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.

Response code format
When a command has been executed correctly

O K

Return code (0DH, 0AH)

A response is returned after a command is executed.

When a command has not been executed

E R R

Return code (0DH, 0AH)

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

WA I T

Return code (0DH, 0AH)

Some commands return “WAIT”. In this case, a value will be returned if you wait a while. Do not send any command 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. VOLM0020 OK
Interval of 100 ms or more
INPS0001 WAIT OK
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.

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 on 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. 1. Specify the IP address and data port number (Default setting: 10008) and connect the computer to the monitor. When connection has been established successfully, [Login: ] is returned as 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 response. 3. Send the password. · Send [password] + [ ]. · If the password is not set, send [ ]. · When the transmission is successful, [OK ] is returned as response.
(2) Send commands to control the monitor. · The commands used are the same as those for RS232C. 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. 1. 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.
