    Data Transmission "No twisted wires"

    Hello friends

    Does it exist a serial connection for a distance of 200 meters without twisted wires ?

    bandwidth = 10kbit
    distance <= 200 meters
    There is no way to use twisted wires
    Is there a protocol for this?






    Thank youو

    1) Very strange request.
    2) Fiber optics.
    3) Wireless.

    oh, yeah, coax.

    And tin cans and string.

    You don't mention required data rate...

    What else if not twisted wire pair? Telephone landline?

    Re: Data Transmission "No twisted wires"

    Thank friends. In fact, We only have a normal wired cable .
    I can not use any other wires. Wireless is not responsive

    Is there a way?
    The main problem is the current induction And loss of connection

    i try RS485 & CanBus But none worked or worked very poorly


    Thanks in advance

    Re: Data Transmission "No twisted wires"

    What do you mean a "normal wired cable"? Lamp cord? And, again, what is your data rate?

    And RS-485 is good for 1200 meters. Your cable must be pretty low quality.
