Controlling the Monitor via Secure Communication (LAN)
You can control this monitor with secure communication from a computer via network.
TIPS
- This monitor must be connected to a network.
- Set “LAN Port” to ON in “ADMIN” > “COMMUNICATION SETTING” on the Setting menu and configure network settings in “LAN SETUP”.
- Set “COMMAND (LAN)” to ON in “ADMIN” > “CONTROL FUNCTION” on the Setting menu.
- The settings for the commands are set in “NETWORK – COMMAND” on the web page
Control via secure communication
User authentication and encrypted communication can be performed using public key cryptography. To perform secure communication, a private key and public key must be created in advance, and the public key must be registered with the device. Client software that supports secure communication is also required. N-format commands and S format commands are used to control this device. Please also read the instructions for each format.
Creating Private and Public Keys
Use OpenSSL, OpenSSH, or a terminal software to create private and public keys. The following public key methods are supported in this monitor.
RSA(2048～4096bit
DSA
ECDSA-256
ECDSA-384
ECDSA-521
ED25519
OpenSSH is available as standard on Windows 10 (version 1803 or later) and Windows 11. This section describes the procedure for creating an RSA key using OpenSSH (sash keygen) on Windows.
-
Open a command prompt from the Start button.
-
Send the following command to create the key with the following setting:
key type:| RSA
---|---
Length| 2048bit
passphrase:| user1
public key comment:| rsa_2048_user1
file name:| id_rsa -
“id _rash” – private key and “id_rsa_pub” – public key will be created. Keep the private key in a safe place. For details of the commands, please refer to the description of each tool.
Registering a public key
Register the public key on the Web page of the device.
-
Set “HTTP SERVER” to ON in “ADMIN” > “CONTROL FUNCTION” on the Settings menu.

-
Se t “COMMAND CONTROL” to ENABLE
-
Set “SECURE PROTOCOL” to ENABLE and push APPLY button.
-
Set “USER1 – USER NAME” to user1 (default).
-
Enter the symbol name of the key to be registered in “PUBLIC KEY – USER1”, and REGISTER the public key you just created.
Command control via secure communication protocol.
This device can be controlled via secure communication using SSH authentication and encryption functions. Implement “Creating Private and Public Keys” and “Creating Private and Public Keys” procedure before
- Click “NETWORK – COMMAND” menu on the web page. Enable “COMMAND CONTROL” and “SECURE PROTOCOL” and push APPLY button in ” NETWORK – COMMAND “
- Connect the computer to the monitor.
- Start SSH client, specify the IP address and data port number (Default setting: 10022) and connect the computer to the monitor.
- Set the user name and the private key for the registered public key, and enter the passphrase for the private key.
- If the authentication is successful, the connection is established.
- Send commands to control the monitor.
- Use N-format or S-format commands to control the monitor. For details on commands, refer to the manual for each format.
TIPS
- If “AUTO LOGOUT” is on, the connection will be disconnected after 15 minutes of no command communication.
- Up to 3 connections can be used at the same time.
- Normal and secure connections cannot be used at the same time.
