RS485 to Ehternet/IP convertor

we are designing a system which requires comminucation with remote rs485 devices. We are looking at some sort of RS485 - Ethernet(internet) convertor. The plan is this: 1) install a rs485 to ethernet convertor at each device location 2) obtain a internet connection(static ip possibly) for each device 3) setup a server/custom sofware to poll each device at regular intervals or on demand 4) create a web based front end to view/edit values from each device.

My question is.. 1) What device do you reccomend? 2)anyone who has done this, can you share your experience.

Thanks In Advance,

Look at the EtherPad Baseline 485 or Etherpad Lite/Duo at

If you don't want to have to rewrite your software to handle TCP/IP, you could install the serial redirector software (SerialAnywhere) that will create a virtual serial port on the machine that the software runs

An alternative solution could be to use the web server on the EtherPad product, and using scripting, write a small script that interprets and present that data being polled on the 485 side of things in a web page. All you then have to do is point your browser to the IP address of the EtherPad, see the ABB demo at

for an example of how this works.. It is even possible to have one script running on a single Etherpad that can talk to other EtherPads, but present all the data in one webpage....

Hi Dean.

The others have suggested devices which connect to async serial ports and send/receive the data to IP connected clients. If you are looking for a device that connects to synchronous serial remotes, that's what we do. The SyncServer comes with client libraries for Linux and Windows (source also available), sample application source and is configurable with a web browser.
