These Serial Servers connect serial devices (RS-232) to Ethernet networks, allowing the serial device to become a node on the network. The serial port can be accessed over a LAN/WAN using Direct IP Mode, Virtual COM Port, or Paired Mode connections. VESP211 Serial Servers feature 10BaseT or 100BaseTX copper network. The product is built for use in harsh environments, featuring a heavy duty metal enclosure that is panel (standard) or DIN rail mountable (with optional adapter). The product can operate from a range of DC power inputs and features a barrel connector. It is shipped with a power supply that features a universal AC input with interchangeable blades for North America, Europe, UK, Australia, and China.
