RFM products are now Murata products. WIT2411D Features: * Very high speed, low latency wireless serial data transmission * Robust 2.4 GHz frequency hopping spread spectrum technology * 3.3 volt operation, low power consumption * Small size, light weight * Certified for unlicensed operation in the USA, Canada and Europe Benefits: * Suitable for point-to-point and point-tomultipoint networks * High immunity to interference and multipath fading * Ideal for battery powered devices * Easy to integrate * Worldwide license-free operation * RoHS Compliant 2.4 GHz High-Speed FHSS Transceiver Module WIT2411D transceiver modules are designed to transmit serial data using highly robust 2.4 GHz frequency hopping spread spectrum (FHSS) technology. WIT2411D modules employ RFM's beacon-synchronized TDMA at an RF data rate of 1.2288 Mb/s to achieve very high data throughput and very low transmission latency. WIT2411D transceivers are suitable for both pointto-point and point-to-multipoint networks. FHSS technology provides strong immunity to both interference and multipath fading. The small size, light weight and low power consumption of these transceiver modules make them suitable for a wide variety of applications. WIT2411D modules are certified for unlicensed operation in the USA, Canada and Europe.

WIT2411D (R) 05/11/15 1 of 2 Base Station Operation: Receive Transmit 200 mA 245 mA www.murata.com High Speed WIT2411D modules transmit at an RF data rate of 1.228 Mb/s using beacon-synchronized TDMA to achieve very low transmission latency in point-to-point cable replacement applications or point-to-multipoint (star) network applications. Serial communications between a WIT2411D module and its host can run at up to 921.6 kb/s to further speed data communication. Reliable WIT2411D modules provide both reliable communication and reliable operation. Using highly robust frequency hopping spread spectrum technology, WIT2411D modules provide strong immunity to interference and multipath fading. Using a 24-bit CRC for error detection, automatic retransmit request (ARQ) and a 12K data buffer, error-free transparent communication is automatic. Built-in data scrambling adds a measure of security. Reliable operation is assured through RFM's stringent QA processes. All WIT2411D modules are manufactured in an ISO9000 certified facility. Simple Simple to integrate and use, the WIT2411D's default parameter settings work for most applications. For other applications, software control makes changing parameter settings easy. The WIT2411D, with its small size and low power consumption, is simple to integrate into your product. The WIT2411D's RS-232 style interface with standard 3.3 volt CMOS signal levels makes integration easy. Since WIT2411D modules are certified for license free operation in the USA, Canada and Europe, your WIT2411D based product does not have to repeat radio regulatory approval. Versatile WIT2411D operating parameters are configurable under software control. Even the transmitter power level can be selected using a straight- forward command set. Both point-to-point and point-to-multipoint modes are supported. Two baud rates,115.2 and 921.6 kb/s are provided for serial communication between a WIT2411D and its host. Measuring just 88.9 x 70.0 x 10.5 mm and weighing 48 grams, the WIT2411D can be integrated into fixed, portable or handheld devices with little impact on the size and weight. The low 3.3 volt operating voltage and 100 mA standby current makes the WIT2411D suited to low power applications.
