Serial-to-Ethernet Servers provide a seamless communication bridge between Serial devices and Ethernet traffics. With the server series, the conventional RS-232, RS-485 and RS-422 devices are given an instant access to TCP/IP and UDP connectivity where distance and speed are no longer limited. The series is versatile in which a COM port can be accessed by multiple host computers and multiple serial devices, and a serial device can be mapped onto a host computer via a Virtual COM utility function.
