NCS0401 - OEM version - front


 NCS0401 - OEM version - back


The NCS0401 is a ready-to-use network connectivity platform intended for combined ethernet and serial communications (RS232/RS485) applications.

The NCS0401 integrates an ID1021 module and serial port hardware that allows for direct connection to a RS232 or RS485 interface of an OEM device.


Typical applications for the NCS0401 are:

  • Web interface for OEM product that can be accessed over ethernet.

  • Serial-to-Ethernet bridge, for enabling internet access to OEM device with RS232 or RS485 interface.

Functions that can be realized with the NCS0401:

  • Remote control/configuration of OEM product using ethernet and HTTP, FTP, Telnet.

  • Bridging/tunneling of existing RS232 or RS485 protocol over ethernet.

  • Remote servicing/upgrading of OEM product firmware/software/databases via ethernet.

  • Remote data acquisition & logging over ethernet, periodic retrieval of data using FTP.
