    Your post was moderated because you did not attach the images locally. When using images and zip files AAC prefers you to attach them locally.

    Your image was way oversized so I resized it to allow it to fit on the screen.

    Note that the standard calls for a maximum distance of 120m for 100Base-T cables. The RS485 standard calls for a maximum distance of 1200m. I suggest that you use RS485 communications between your PC and MYBOARD.
    Converting from RS485 to ethernet actually is a reduction in the distance you can achieve. Unless you plan on routing over the Internet... which has its own sets of problems. (On the other hand, RS232 calls for a maximum distance of only 15m)

    yes, I was scratching my head on this. RS485 is used in industrial settings to transmit very long distances; much further than ethernet. RS485 should be used IMO.

    A solution I have seen is fiberoptics. Check out Siemens OLM; it will convert your rs485 to fiberoptic, and then back into RS485
