Data Transmission "No twisted wires"

[azadfalah]

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.

Hi,

Coax, RF...

[barry]

oh, yeah, coax.

And tin cans and string.

You don't mention required data rate...

Try a short haul modem.

Try a short haul modem.

You still need twisted pair for that.

What else if not twisted wire pair? Telephone landline?

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

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.
