Abstract
A device server intended for attaching serial devices to a network includes Ethernet communications, an Ethernet switch, and serial communication capability so that multiple device servers are connected in a “daisy chain” or series pattern. Galvanic isolation of the power supply from the housing and communication ports, screw terminal and modular connections, DIN rail mounting, broad power supply voltage ranges or “Power-over-Ethernet” and operator visible indicator lamps with a pulse stretching feature greatly simplify installation and use.
