Ethernet, WiFi Integration
Ethernet is the most popular communication connectivity used in almost everywhere from factories, offices and homes all over the world. The wireless version of Ethernet is known as WiFi working on 2.4GHz frequency band.
The Ethernet communication connectivity has evolve from a low data bit rate to a high speed of 1Gbps connectivity. It works on a duplex communication with a pair of TX (TX+, TX-) and RX (RX+, RX-) differential signal. The differential signals wire being twisted together helps to maintain the signal integrity, minimum signal distortion (noise) from the environment. Shield cable can be used to further protect the integrity of the communication signal.
Ethernet and WiFi connectivity is strongly recommended integrating to other communication system in the internet all over the world.

Standard recommended maximum communication distance for Ethernet is 100m.

RS232 is a serial data communication and has been around for quite some time. While standard like parallel communication or IEEE488.2 phasing out into the history, RS232 still survive strong.
RS232 needs a minimum of 3 wires to begin communication between devices, namely Rx Tx and Signal Gnd. The single-ended physical signal used for RS232 is simple to decode and configured.
Cost of implementing RS232 connectivity is low.
This table is a reference guide for the communication distance given the baudrate set. The actual distance depends on many other factor like the type of cable use, the noise along the communication cable, etc…

RS485, RS422 Connectivity
RS485 and RS422 is a differential signal communication channel. RS485 and RS422 is using the same physical signalling. The only difference is that a RS485 is a half duplex, while a RS422 is a full duplex communication. Check out this website for duplex communication.
Differential signalling is robust against noise from the surrounding. Twisted pair (twisted wire) is to be use for RS485 and RS422. The twisted wire helps to maintain the signal integrity, robust against unknown noise. Having the wire twisted is more important than everything else as the twisted wire leave no gap between the wire which allow noise to be induce onto the communication medium. Like the Ethernet differential wiring, additional shielding of the cable helps.
