Antaira STE-501C RS-232/422/485 Serial to Fast Ethernet Converter

The STE-501C is a gateway between 1 port of Ethernet (TCP/IP) and 1 port of serial and allows remote monitoring, management and control of industrial field devices.  Capable of accepting either RS-232, RS-422 or RS-485 serial communication, the STE-501C is ideal for adding serial devices to an Ethernet network. Nearly any serial device may be connected.  The STE-501C offers full-duplex, bi-directional data transmission transparent between the serial port and Ethernet network.
