In case the equipment uses a serial port instead of Ethernet, it is enough to install the virtual COM port driver on the computer and use the built-in WebHMI function Virtual COM port. The user can either setup his own VPN network or use the network provided by the Level2 system (recommended). | In case the equipment uses a serial port instead of Ethernet, it is enough to install the virtual COM port driver on the computer and use the built-in WebHMI function Virtual COM port.
