Connecting with Sm@rt Server

Requirements

• Sm@rt Server is enabled and configured on target device.
• TLS encryption is disabled (option Secure communication via self-signed certificate is unticked in Sm@rt Server settings).

Caution

Current version of the application does not support encrypted connection. Client can be used for connecting with other VNC servers but they have to support websocket connection mechanism!

Important

Client can be used for connecting with other VNC servers but they have to support websocket connection mechanism! The app has been tested with Sm@rt Server on HMI Unified Panels and VNC servers running on Linux machines. Tests performed with classic Comfort panels and Windows based, popular VNC servers (like TightVNC) were not successful due to lack of support for websockets mechanism.

Extablishing connection

1. Open app on your panel by clicking the proper tile in your Edge Management.

   

2. Enter connection data - address of your Sm@rt Server and port number (default port is 5900, you can change it in Sm@rt Server settings) and click Connect button.

   

3. If the server is accessible in you network and connection data was correct, you will be prompted for password. If the password is correct, you should have access to the runtime and panel OS.
