Ultimately, it can be thought of in a way that serial communication is more made for this usage as compared to the common USB and ethernet. Serial communication is a way to send data. It is essentially a form of serial communication. Depends what you mean by a serial cable - Fibre, Ethernet, RS232, RS485, RS422, USB, HDMI, SMPTE292 are all examples of serial communications media. We feature RS232, RS422, RS485, USB, and ethernet devices using copper and fiber. In addition to the serpentine pair configuration, STP cables feature a metallic shield surrounding the conductors. Be sure to use a wire pair such as the blue and blue/white pair for the data lines and a third wire or pair twisted together for the common connection. In short, RS485 is a standard defining the electrical characteristics of serial lines for use in serial communications 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.

If your system is unreliable, flakey, or blows up from time to time, you need to talk to us. RS485 is used more industrially where many devices need to be interconnected together for a system. The cornerstone of this complex system is a dependable physical sensing network! Compared to serial communication, USB and ethernet are significantly more complex and expensive. The rs485 shielded cable is known for supporting multi-point communication, meaning multiple devices can be connected to the same network, facilitating versatile and complex setups. The design of RS485 is targeted towards it being tolerant and forgiving to noise and long cable runs with the twisted pair cable arrangement. The latest point of view on RS485 cables includes advancements in design to support higher data rates and improved resistance to environmental factors such as temperature fluctuations and moisture. Supports Third-party Data Loggers and IoT Platforms: Besides SenseCAP Data Logger, developers could connect to other data loggers that support MODBUS RS485 protocol and third-party IoT platforms.

Modbus devices communicate using a Master-Slave technique where only one device (the Master) can initiate transactions (AKA queries). There are many standards in serial communication and RS485, also known as TIA-485 (-A) or EIA-485, is just one of them. There are different serial communication standards such as RS232, RS422 and RS485. Serial communication also has a deterministic behaviour to avoid collisions of data packets, making it more reliable for a linkage system with many devices. This whole system allows manufacturing facilities to control their devices remotely and also set-up automation. Developed by Modicon, Modbus enables different devices from different manufacturers to be integrated into the main system. The main difference between them is in the hardware. RS485 is also used in performance venues to control lights and systems such as the one shown below. This allowed users in manufacturing facilities to connect larger applications and whole machines with one protocol.

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. Modbus is the world’s most popular automation protocol in the market. Most Modbus implementations use RS485 due to the allowance of longer distances, higher speeds and multiple devices on a single network. RS485 is used as the physical layer for many standards and proprietary automation protocols to implement control systems, most commonly Modbus. The outer layer of aluminum foil covers the entire conductive core, serving to counteract high-frequency interference. International duties & taxes may apply and are not calculated at checkout.

You may be wondering, what can I do with serial communications, especially RS485. It may sound complicated for those who don’t know what is serial communication, so here’s an explanation.
