Description The Radio Frequency Modules () is high performance transceiver (RX&TX) modem designed for wireless data transmission between two devices. The transceiver has the functions of a complete radio modem and simply require TTL/RS232/RS485 data at the transmit input and the corresponding transceivers output the same data. The bases on the CC1000 transceiver with a PA on the TX path. The module incorporates a high speed MCU and integrates efficient FEC engine. Feature Support 64 channels with the max. output power up to 20 dbm (100mW) Adjustable operating frequency via command tool with min. 0.5MHz interval Adjustable output power via command tool with min. 0.5dBm interval Adjustable port interface and baud data rate Support 3.3V/5V TTL and RS232 interface Support auto frequency hopping to increase anti-confusing capability Integrated a high performance MCU to enhance the communication reliability via FEC algorithm Support standby mode via command tool Applications 433MHz ISM/SRD band systems Wireless data collection Water, Power, Gas meter Parking meter Industry Telemetry Equipment Controlling and Monitoring Automatic Meter Reading Wireless alarm and security systems Wireless queue machine Wireless voting system Home automation Make Your Business Creative 2 www.smartrf.com.cn

Precautions Wrong operation The noise of the power is high The antenna position is not appropriated Din/Dout line is broken DIN/DOUT is connected inside out The interface is incorrect abnormal communication Abnormal result caused 1. The sensitivity dropping 2. The shorter transmission distance 1. The metal shield and building will influence the performance 2. The antenna has directionality 3. The system noise will have interference on the antenna 4. The antenna position is too low declines the performance 5. The shorter transmission distance due to the antenna can not be joined closely The module can not transmit or receiver the data The module can't transmit functionally The data received are regular, but incorrect (TTL/RS232/RS485 mode and user's interface are mismatched ) Communication agreements of both ends are inconsistent 1.Baud rate is inconsistent 2.Parity bit, data bit and stop bits are different from each other 3.The frequency of both ends are inconsistent 4.It is not the same series of products 5. The /SET does not connect the high level Voltage Don't take pull out and insert the wireless mould while the power is on; Use the linear steady voltage or battery for the supply power, don't use switch power; About the distance index, different test environments will produce different results, the main influence factor includes: Output power, receiver sensitivity, transfer rate, interfere intensity (background noise), aerial gain, from aerial to ground highly, move, space decay, barrier size and position.
