942084999-10 Application Field and Working Principle

942084999-10, also known as 9420, is a type of serial data communication protocol developed by the Welsh Consortium. It is used in a number of applications, ranging from industrial automation, robotics, and medical instrumentation, to marine navigation.

Principle of Operation

9420 is primarily designed as an asynchronous serial communication protocol, meaning that each device connected to it must have its own clock that governs transmission and reception of data. The protocol uses a simple "request-response" system, where a device sends out a request and waits for a response from the other devices connected to it. This ensures that no two devices try to transmit data to each other at the same time.

The protocol also supports various forms of data encoding, including 8-bit binary and 16-bit integer formats. Depending on the application, various encoding schemes may be utilized. These include binary-coded decimal (BCD), Manchester code, and non-return-to-zero (NRZ).

Applications

9420 is particularly well-suited for industrial automation applications. It is fast and easy to program, and its relatively low transmission rate makes it ideal for slow-speed processes. Some of its more common uses include control of motors and solenoids, and the monitoring of sensors and other devices.

9420 is also used for data communication between embedded systems. Its small size and readily available transmitter and receiver ICs make it a popular choice for embedded projects. In addition, its low cost and simple protocol make 9420 ideal for small-scale or prototype applications.

9420 is also used in medical instrumentation systems, primarily for the control and monitoring of various medical supplies and equipment. The protocol’s low speed and low data rate make it ideal for use in these sensitive systems.

Finally, 9420 is also used in marine navigation. The low data rate of the protocol makes it well-suited for transmitting navigation data over short distances, such as between a ship and a shore station.

Conclusion

942084999-10 is a serial data communication protocol developed by the Welsh Consortium. It is designed for low-speed asynchronous data transmission, and is used in a variety of applications, including industrial automation, embedded system control, medical instrumentation, and marine navigation. The protocol is simple to program and relatively inexpensive, making it a popular choice for many applications.
