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
 

oh, yeah, coax.

And tin cans and string.

You don't mention required data rate...
 
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
 

Hi,

i try RS485 & CanBus But none worked or worked very poorly
This is expectable.

A powerline modem .. maybe...

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.
