If there is a lot of environmental electrical noise then an optical isolated converter is preferred.It converts RS232 signals to half-duplex RS485 balanced differential signals and can extend.It converts RS232 signals to half-duplex RS-485 balanced differential.It converts RS-232 signals to half-duplex RS-485 balanced differential signals or RS-422 full-duplex.
Rs232 Rs485 Converter Trial And CommercialThe hardened ABS plastic housing with optional built-in DIN mount bracket makes this converter ideal for any industrial and commercial application. The RS232. It effectively protects your RS232 line and your equipment and data communication against. This RS232 optical isolator offers a strong industrial grade and effective protection against all high voltage spikes, surges, static. These RS232 repeaters RS232 extenders, also called line drivers, can extend your standard RS232 line up to 4000 feet. These extenders work in pairs only, one is connected at each end of. The typical serial converter does this in both directions which is also referred to as a bi-directional converter. Some of these converters can convert from RS232 to both RS485 and RS422 however many standard models only has one of the protocols. 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 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. 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. The typical common-mode voltage range for a RS485 converter is -7V to 12V. Usually a RS232 - RS485 converter is the preferred way to establish multi-point networks when working with RS232 devices. This is a method for connecting multiple RS485 devices with each other over a two-wire network. 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. ANSITIAEIA-422-B is the American national standard for the RS422 protocol. 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. ![]() Due to loading limitations one of the best uses of a RS232 to RS422 serial converter might be in point-to-point communications, such as extending an existing RS232 line. Extending a RS232 line is done by converting the RS232 signal into RS422 and then back to RS232 at the remote end. This way you can extend the RS422 signal for up to 4000 feet. For example you need to consider the noise level in the environment surrounding the serial converter.
