This unit is designed to provide an RS-422/485 connection to fiber cable where the connected devices have RS-422/485 interfaces. It enables serial devices such as CNCs and PLCs to instantly connect to an existing Ethernet / Fast Ethernet network. This Serial-to-Ethernet Device Server is a robust device controller for MIS personnel. Now you can attach up to four serial devices to Fast Ethernet by using one device.
