Two serial converters can also connect directly to each other via an Ethernet cable. Two serial converters will connect to each other (TCP server-client model) via a local LAN/WLAN, or even the Internet.
With Serial Tunneling, two serial devices can communicate with each other from anywhere.Įach Serial device will connect to a Serial-to-Ethernet or a Serial-to-WiFi converter. Serial Tunneling allows us to overcome this limitation. Communication between two serial devices via a serial interface (RS232, RS485, or RS422) has a limitation of distance (the distance is limited to 15m for RS232, and 2km for RS422/RS485).
