VLINX ESR90x Industrial Ethernet Serial Servers allow connection of RS- 232, RS-422 or RS-485 devices to an Ethernet network. The serial ports can be accessed over a LAN/WAN using Direct IP Mode, Virtual COM Port, or Paired Mode connections. The 10/100 Mbps Ethernet connection auto- selects 10BaseT or 100BaseTX and indicates the type of connection with a bi-color link light. ESR90x serial servers are built for use in industrial environments, featuring an IP30, approved slim line DIN rail mountable case. They operate from a range of AC or DC power supply voltages, support redundant DC power and feature terminal block power connectors.
