The Device Servers are billed as a drop-in solution to add network connectivity to non-networked devices and equipment. With one connection for the network, and the other for attached RS-232/422/485 serial devices, Device Servers encapsulate serial data for transport over Internet Protocol (IP) networks. Used together in pairs as an extension cable for serial devices, or separately with a host computer or PC, Device Servers are well-suited to overcome the inherent distance limitations and point-to-point nature of serial devices.Advantech Corp.
