raspi-config no longer offers Internationalisation Options.Most Modbus implementations use RS485 due to the allowance of longer distances, higher speeds and multiple devices on a single network.Raspberry Pi configuration has changed as of Jessie (2017): Developed by Modicon, Modbus enables different devices from different manufacturers to be integrated into the main system. Modbus is the world’s most popular automation protocol in the market. RS485 is used as the physical layer for many standards and proprietary automation protocols to implement control systems, most commonly Modbus. RS485 is however most popularly used in programmable logic controllers and factory floors where there are lots of electrical noise. This is due to the minimal wiring required due to the wiring configuration requirements of RS485. Commercial aircraft cabins also use RS485 for low-speed data communications. In computer systems, RS485 is used for data transmission between the controller and a disk drive. Some of the examples are robotics, base stations, motor drives, video surveillance and also home appliances. RS485 is used in many computer and automation systems. However, Arduino and Raspberry Pi hobbyists also use it for some of their projects when multiple peripherals need to be linked to the board. RS485 is used more industrially where many devices need to be interconnected together for a system. The RS485 is also common in computers, PLCs, microcontrollers and intelligent sensors in scientific and technical applications. Due to this and it being able to transmit data over long distances, the RS485 is used commonly as a protocol for POS, industrial and telecom. It is known for being able to be used effectively over long distances and in electrically noisy environments. This standard is a product of joint efforts by the Telecommunications Industry Association and the Electronic Industries Alliance ( TIA/ EIA).

There are many standards in serial communication and RS485, also known as TIA-485 (-A) or EIA-485, is just one of them. You can find out more about the differences between RS485 and RS232 here. The main difference between them is in the hardware. The most widely used communication standard is RS232. There are different serial communication standards such as RS232, RS422 and RS485. Ultimately, it can be thought in a way that serial communication is more made for this usage as compared to the common USB and ethernet. Serial communication also has a deterministic behaviour to avoid collisions of data packets, making it more reliable for a linkage system with many devices. Now, why don’t companies just use USB or ethernet to transmit data between their devices? Compared to serial communication, USB and ethernet are significantly more complex and expensive. As mentioned, an example of serial communication is RS485. Manufacturing facilities use serial communication to link their devices together. It is like the Universal Serial Bus ( USB) or ethernet that we can find in many of our modern computers. Serial communication is a way to send data. It may sound complicated for those who don’t know what is serial communication, so here’s an explanation. It is essentially a form of serial communication.
“In short, RS485 is a standard defining the electrical characteristics of serial lines for use in serial communications systems.
