What is Serial Communication?

It is built to last with its aluminium alloy enclosure. Ready-to-deploy Industrial-grade Outdoor Enclosure: IP66 waterproof rate outdoor enclosure with window and waterproof ventilation hole reserved for light and gas sensors, also comes with a customized mounting panel. This is where the RS485 1-to-4 Splitter/Hub comes in! Grove sensors to MODBUS RS485 industrial-grade sensors. Most Modbus implementations use RS485 due to the allowance of longer distances, higher speeds and multiple devices on a single network. RS485 main advantages as compared to other serial communication are tolerance to electrical noise, lengthy cable runs, multiple slaves in one connection, and fast data transmission speed. However, in a full-duplex setup, they are limited to a master and slave communication where slaves cannot communicate with each other. Another major advantage is that there can be more than one slave in the connection. This is great for Supervisory Control and Data Acquisition (SCADA) systems where there are many devices and it also comes at a very low cost to implement. Designed with industry standards, what is rs485 cable it comes with a waterproof aviation connector to ensure that your connection will not be affected by the elements.

It is IP66 rated, waterproof and dustproof, which makes it ideal for long-term remote environmental monitoring in indoor and outdoor severe environments. Being a connector that is frequently used outdoors in severe environments, it is designed to be IP68-rated waterproof and dustproof. The design of RS485 is targeted towards it being tolerant and forgiving to noise and long cable runs with the twisted pair cable arrangement. RS485 is used as the physical layer for many standards and proprietary automation protocols to implement control systems, most commonly Modbus. In computer systems, RS485 is used for data transmission between the controller and a disk drive. 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. RS485 has many advantages over other standards, especially when it comes to applications in noisy industrial environments. In RS485 standard, data is transmitted via two wires twisted together also referred to as "Twisted Pair Cable". In this setup both the TX and RX share a single pair of wires, therefore it is limited to half-duplex data transmission as the data cannot be transmitted simultaneously to and fro each device. Modbus devices communicate using a Master-Slave technique where only one device (the Master) can initiate transactions (AKA queries).

However, what if you want to use RS485 in your projects but your device only has USB support? RS485 is also used in performance venues to control lights and systems such as the one shown below. It is commonly implemented to control video surveillance systems and link security control panels to devices such as access control card readers. As mentioned, RS485 is used to link devices instead of other means as it provides significant advantages. There are different serial communication standards such as RS232, RS422 and RS485. Fret not. There are tools available that can be used to convert your USB ports to RS485. If you’re very sure that you are only using RS485 then you will not be disappointed with the former. However, if you’re looking to experiment, the latter will provide you with more versatility. However, if you’re looking to experiment, the latter will provide you with more versatility.

It is unquestionably an ideal choice for industrial equipment use due to its high speed, reliability, safety and versatility. Now, why don’t companies just use USB or ethernet to transmit data between their devices? It may sound complicated for those who don’t know what is serial communication, so here’s an explanation. Here’s an example of a SenseCAP RS485 sensor! Commercial aircraft cabins also use RS485 for low-speed data communications. In short, RS485 is a standard defining the electrical characteristics of serial lines for use in serial communications systems. RS485 is used more industrially where many devices need to be interconnected together for a system. Developed by Modicon, Modbus enables different devices from different manufacturers to be integrated into the main system. Devices will be linked together via a bus configuration as shown in the picture above. If you’re very sure that you are only using RS485 then you will not be disappointed with the former.
