What is the meaning of RS232?
The term RS232 stands for "Recommended Standard 232" and it is a type of serial communication used for transmission of data normally in medium distances. It was introduced back in the 1960s and has found its way into many applications like computer printers, factory automation devices etc.
What is RS232 port used for?
An RS-232 serial port is most often used by repair technicians to perform diagnostics and service updates. It may also be used to control a device when connected to a computer running a home automation system or Custom Integrated Audio/Video (A/V) system, such as the CAV-M1000ES Multi-room A/V Distribution System.
What is the difference between RS232 and USB?
RS232 is a definition for serial communication on a 1:1 base. … RS232 ports can be either accessed directly by an application, or via a device driver in the operating system. USB on the other hand is a bus system which allows more than one peripheral to be connected to a host computer via one USB port.
What is RS232 vs RS485?
RS232 is more than able to perform for a short distance and low data speed requirements. RS232 has a transmission speed of 1Mb/s up to 15M. However, RS485 has a data transmission speed of up to 10Mb/s for a distance of 15M. At the maximum of 1200M, RS485 transmits at 100Kb/s.
Why RS-232 is called so?
There was an old Ma Bell standard for wiring between modems and terminal devices, it may have been called RS-232. The IEEE adopted it as a standard a while later. It's a bipolar signaling method, harking back to the days of bipolar teletype signals and polar relays.
Who introduced RS-232?
the Electronic Industry Association Today, the most popular serial communications standard is certainly the EIA/TIA-232-E specification. This standard, which was developed by the Electronic Industry Association and the Telecommunications Industry Association (EIA/TIA), is more popularly called simply RS-232, where RS stands for \"recommended standard.
Is RS-232 an Ethernet cable?
Nope. RS232 is a format for serial communications, usually in a DB9 or DB25 connector, but can be in all sorts of connectors and signal “formats”. You can make adapters to use UTP Ethernet cables with RJ45 connectors but it's not Ethernet at all.
What devices use RS-232?
A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connections not only to modems, but also to printers, computer mice, data storage, uninterruptible power supplies, and other peripheral devices.
