RS-485 is also used in building automation as the simple bus wiring and long cable length is ideal for joining remote devices. So in your typical office building, you're probably running hundreds of feet if not thousands of feet just from one end of the building to the next. Some of these converters can convert from RS232 to both RS485 and RS422 however many standard models only has one of the protocols. Perhaps the most successful serial-data standard for PC and telecom applications is the RS-232. A RS232 - RS485 converter is often used in industrial data acquisition and control applications where multiple serial devices communicate with each other through a converter. Usually a RS232 - RS485 converter is the preferred way to establish multi-point networks when working with RS232 devices. By using repeaters very large RS-485 networks can be formed. However since only a true RS485 network can have addressable serial RS485 devices, the RS232 converter needs to be addressable either by software or by DIP switches when using it in this type of configuration. The parameters chosen for a current transformer are not only the rated current, the secondary current and the power, but also the type of assembly.
Serial port monitoring and data processing algorithms are extremely optimized in order to provide you with slick user experience and eliminate all negative impact on operating system performance, stability, computer resources consumption, and introduction of communication delays even at high non-standard data transfer rates. So in order to transfer data from a RS232 serial interface engineers need a converter to be able to connect to a RS485 or RS422 interface. The advantage of the RS485 protocol is that this it can transfer data over longer distances, up to 4000 feet, and have up to 32 nodes per single network, and it can be used for multi-point networks where multiple serial devices are setup in a bus network. RS-485 supports inexpensive local networks and multidrop communications links, using the same differential signaling over twisted pair as RS-422. The RS422 converter is used for data transmission, using balanced or differential signaling, it is mainly used in industrial and commercial environments since lots of process equipment and machinery have this protocol built-in. Even RS485 is not commonly as popular as RS232 it is extremely useful for converters in industrial and commercial environments.
Most newer consumer electronics comes with an USB, Firewire or other high-speed communication port, however a lot of industrial and commercial equipment, both old and new, is made only with a RS485 or RS422 serial communications port. There are several factors to consider when choosing a RS232 - RS422 converter. Why use a RS232 - RS485 /RS422 converter? This is a method for connecting multiple RS485 devices with each other over a two-wire network. It is an approved and standard protocol by American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), American National Standards Institute (ANSI), and International Organization for Standardization (ISO).Use with Structure View data visualizer, Text Exporter or Custom View data visualizer to get full insight on underlying protocol messages exchanged by devices on your network. A RS232 - RS422 converter is a 4-wire, full-duplex, differential protocol with multi-drop capabilities and a recommended distance limit of 4000ft. ANSI/TIA/EIA-422-B is the American national standard for the RS422 protocol. The RS232 - RS422 converter is also often used in older serial devices such as older PLC's and terminal equipment. Some of the typical applications of RS-485 is point of sale equipment. The reason is that the serial RS232 protocol is, even its old, a very reliable, stable and solid communication protocol, which can easily be implemented with existing industrial equipment.
With the increasing popularity of laptops and tablets, still, these are not able to perform as good as a solid desktop. The serial RS232 to RS485 converter and RS232 to RS422 converter units, also called serial converters, are small electronic devices used to convert a serial RS232 signal, (for example the COM port in older computers) into either RS485 or RS422 signals. As a result, it has become challenging for the computers to take up as little room as possible, while maintaining power comparable or even sometimes offering greater functionality than their counterparts. You probably have heard of RS232 which is a serial communication method between computers and devices , but have you heard of the RS485 communication? But before we dive deep into those SATA cable classifications, we need to have a look at what SATA actually means. Introduction Whenever you need to connect a storage device to a computer motherboard, you must have seen a bunch of ribbon or flat like cables being used for the purpose. As serial-data standards tend to evolve separately within particular industries, we thus have more standards than we should.
