Long Distance Wired Serial Communication with Arduino using RS485 and CAT Cables

[ramikoco]

thanks a lot
So, is there one for this circuit for full-duplex?

[bettergrades]

What do I do if I want to transmit data from multiple sensors across the rs485 module?
Please help.

okay, and what when i want communicate for example 10 arduinos and i want to can communicate with each of them, but i want program them with same slave code, how to make that?

Can you kindly give me idea about the connector on the rj45 terminal, Im seeing 3 wires .

[sanjaybhatikar]

Awesome, dude! Very clearly explained.

Hi, if i have like 10 sensors reading values from arduino, can i send these 10 values through cat 6?😊

Hello! Thanks for the awesome tutorial. Just one question, What's the highest baud rate can be used for about 5 meter cable?

Hello, can I ask if it still working using Serial.begin(115200). I have tried with 115200 baud and I couldn't make it work. But I used a regular 2 poles cabled (not twisted or shielded). And I used this module similar to yours but bidirectional.

Can both arduino work as transmitter and receiver?
Plz reply

Hello! thanks for this lovely video. Can I use A1 pin instead of pin number 8 with RS-485.

Hi, is it possible to transfer realtime cam view from one arduino to another via UTP cable ?

[chamudithanuwan]

What is the maximum distance of thi cable ?

I have a cable tv connection. and same for my friend. Can i use this channel to transmit message? Arduino or Raspberry. The distance is between 5 to 10km. The cable reaching my home is of copper coaxial and in-between I think they use ofc and some repeaters. How can I utilize this channel?
