What is "serial tunneling"?
Serial tunneling is a bidirectional communication method that Ethernet-enables serial devices. This allows asynchronous serial devices to communicate over an Ethernet network without requiring costly changes to application programs or device firmware. Barcode scanners, RFID readers, scales, sensors, and hundreds of other serial devices can be located remotely on the network, yet communicate with a host serial device as though they were directly connected to a local serial port. You can achieve serial tunneling with two Sealevel Ethernet Serial Servers paired together by configuring their IP addresses, thus creating an active network connection. When one serial server receives serial data, it initiates a connection, converts the data into network packets and transmits the data to the other serial server. Sealevel’s family of Ethernet Serial Servers (running firmware v2.2 or greater) support Serial Tunneling. View Sealevel Ethernet serial servers…
