    RS-485 Vs Ethernet
    We have Programmable logic controllers that have two connections
    One is an Ethernet port RJ-45
    The other is an RS-485 port RJ-11
    I use an NIC for one and an RS-232 /RS-485 converter for the other

    What is the difference?
    Does the Ethernet use TC/IP?
    Do both use three wires?
    Is the data transmitted differently?
    Thank you

    Ethernet is the defacto standard for LANs. For a time it was a battle between Token Ring and Ethernet, but Ethernet won out.

    This site has a good explanation of RS-485 and its uses.

    There are umpteen sites that explain Ethernet.
