Weintek’s Model MT8053iE dual-Ethernet HMI is available in a 4.3-in size. The dual Ethernet port allows the device to be on two independent networks, whereby one port connects to the controller, and the other one connects to the host computer or is used for remote control (e.g., built-in EasyAccess 2.0). Separation of networks eliminates network interference and congestion and also helps to improve data transfer reliability and stability.
