The RPM873-E2A is an IrDA transceiver module designed for serial data communication over a non-contact infrared link. It is a complete serial-to-infrared data link which uses the IrDA standard protocols to enable two-way wireless communication between devices. The module combines an infrared receiver and transmitter with a low-power microcontroller to provide a cost-effective solution for short-range communication.The RPM873-E2A is suitable for applications which require wireless serial data communication over short distances, such as computer peripherals, medical instruments, consumer electronics, industrial automation, automotive infotainment and home automation systems. It supports a range of serial protocols, including RS-232, RS-422 and RS-485, enabling it to be used in a wide variety of applications.The module is powered by a single 3.3V power supply and is capable of operating at data rates of up to 115.2K bps. It is also compatible with all IrDA standards from 0.6K to 4 Mbps, including SIR, IrLAP and VFIR. The module features on-board voltage regulators which allow it to operate over a wide range of input voltages. It is RoHS compliant and can be operated in temperatures ranging from -20 to +85°C.The module consists of an infrared transmitter and receiver, a low-power microcontroller and an SPI-compatible programmable logic controller. The microcontroller is used to process and manage the data signals being transmitted and received. It also provides a range of features which helps to reduce power consumption, such as a low-power sleep mode and an automatic shut-down function for when communication is no longer required.The IrDA standard is used to ensure that data is transmitted with a high degree of accuracy and reliability. It uses an algorithm known as pulse position modulation (PPM) to ensure that data is accurately transmitted over the wireless link. The PPM algorithm works by transmitting a succession of pulses which encode a data pattern. The distance between the pulses is used to represent the data. This ensures that data is transmitted with a high degree of accuracy, even over a noisy or changing environment.The working principle behind the RPM873-E2A is fairly straightforward. It uses the infrared frequency band to transmit and receive data. The transmitter part of the module modulates the data signal into a pattern of pulses and sends them out into the environment using the infrared light emitted from the LED. The receiver part of the module uses the LED to detect any reflections of the infrared light back from the environment. These reflections are then demodulated and the original data signal is recovered.In summary, the RPM873-E2A is an IrDA transceiver module which is designed to be used for serial data communication over a non-contact infrared link. It provides a reliable and cost-effective solution for short-range wireless communication and is compatible with a range of serial protocols. It is powered by a single 3.3V power supply and utilises an IrDA standard protocol to ensure that data is transmitted with a high degree of accuracy.
