Where to Use RJ45 Connectors

RJ45 is a type of communication protocol that is used for Ethernet and other long distance communications. In this type of communication, Data is transmitted between two electronics devices like Microcontrollers or Microprocessors over a very long distance without getting it lost. Normally communication protocols like SPI, USART, IIC will be used to transfer these data. These two devices are linked using a cable like CAT cables. The CAT cables are connected to the circuit through this RJ45 Connector. These connectors support any type of Ethernet cable like USP, CAT5e, CAT6, etc.

There are also many types of RJ45 connectors, but they all serve the same function other than the appearance and built quality. So if you are looking for a connector to communicate through RJ45 Protocol, then this connector might be the right choice for you.

How to use RJ45 Connector

The RJ45 connector has 8 pins as shown above. It is very important to select the appropriate pins for your data and ground to make the RJ45 protocol work efficiently. The main advantage of using RJ45 communication is that they are connected using CAT cables. These CAT cables are made up of twisted paired wires and the wires are housed inside a cable which can protect it from external noise. Since the wires are twisted in a pair of two, among these two wires one will be used to carry the signal or the data and the other will be a ground wire which will remove the noise from the data wire during high distance transmission.

A simple sample connection diagram for a USART connection with two RX and TX data lines is shown below:

The data lines can be anything from USART, SPI or even IIC. Note that in every twisted pair one wire carries the data and the other is connected to ground. Other alternative methods for this protocol are the RS232 communication and the RS485 Communication protocol. These cables also support POE (Power over Ethernet) and hence can also carry power to the modules if required
