RPM872-H12E4

RPM872-H12E4 is one of the Infrared Data Association (IrDA) Transceiver Modules, which is a serial infrared transceiver solution that includes an on-board, low-power transmitter and receiver IC, and a demodulator/demultiplexer IC. It provides a fully compliant system for embedded short-range infrared communication applications between infrared end nodes.

RPM872-H12E4 is designed to cover a wide range of applications, including consumer or home applications and industrial or medical applications, including remote infrared control, the transfer of data or power from the handset or remote controller. For applications that require a longer transmission range, an external infrared filter can be added to the front end of the receiver. This will significantly reduce false triggering while maintaining the same receiver sensitivity.

The working principle of the RPM872-H12E4 module is based on the principles of encoding and decoding of optical signals. The module contains an on-board receiver and transmitter circuit, which is integrated with a demodulator IC, and a demultiplexer IC. The encoding and decoding process happens within the receiver and transmitter part. Encoding is done through the modulation of the receiver signal with a signal generated from the transmitter part. Decoding is done by the demodulator IC, which processes the received signal and generates the output data.

The module supports both Open Protocol and Closed Protocol infrared communication protocols. The Open Protocol protocol is mainly used with consumer and home applications, while the Closed Protocol protocol is used for industrial and medical applications. The Open Protocol protocol requires simple design and implementation, while the Closed Protocol requires more complex design and implementation.

Moreover, the RPM872-H12E4 module is compliant with IrDA protocol standards and supports a wide range of data rates from 9.6 kbps to 115.2 kbps. It also supports short-range, low-power communication in various industrial, consumer, and home applications, which makes it suitable for communications between remote infrared-enabled nodes.

In conclusion, the RPM872-H12E4 module is a versatile and powerful IrDA transceiver module that provides both Open and Closed Protocol infrared communication protocols. It is designed for short-range, low-power communication in various applications, from consumer-based to industrial and medical applications. Additionally, it supports a wide range of data rates for increased flexibility and improved data transfer speed.
