The Digi One SP IA serial server allows any industrial device with a serial port to be easily connected to Ethernet. The compact device server features one RS- 232/422/485 DB-9 serial port making it an optimum solution for many industrial automation applications. The Digi One SP IA supports most industrial automation protocols through serial tunnelling, TCP/UDP connections, or Digi's patented RealPort software. RealPort makes it possible to establish a connection between the host and networked serial device by creating a local COM or TTY port on the host computer, allowing existing software applications to work without modification.
