Questions tagged [twisted-pair]
Most commonly a type of transmission line that consists of two individual wires twisted together. Its differential nature attenuates common-mode interference present in the environment, which is useful in the transfer of differential signals (even low-frequency ones). It is commonly used for differential digital communication protocols such as ethernet.

I was testing my display port diagram, all 4 lines.
The first three look good, the 4th line looks like it has only one signal (not differential.)
My question:
Is the 4th line okey to be like this. (...

RS232 and RS485 sharing same wires
I'm planning a serial port that can either work as RS485 (half duplex mode) or as RS232 (configurable by the user).
There are several UART to RS232/485 chips around (like LTC2873), where a GPIO ...

Can I use thicker wires or twisted pair for Ethernet?
I'm planning to use 2 types of connectors:
A : GND + 24V + 100Mbps ethernet (4 wires) + 2 wires with various functions
B : 1 Gbps ethernet with PoE (8 wires)
For type B, I found of the shelf ...

Twisting four CANBUS wires (High, Low, GND, PWR)
From what I understand, the High/Low CAN wires must be a twisted pair and it seems like a bad idea to create a 3-wire braid with the High/Low along with the GND wire, let alone with PWR.
Just to be ...
