Wireless Module

High sensibility, good performance and perfect parameter, integral screen shell and embedded filter are used for better interference immunity in harsh environment. This series of modules are specially designed for field wireless communication where the professional requires the stability as the key. The modules have FCC, CE and RoHS certificates and been integrated in many export-oriented products. ============================================================== HAC-UEM Series Ultra low power data radio module is suitable for: ﹡Auto Meter Reading system. ﹡Remote control and monitoring. ﹡Data collecting in product lines. ﹡Data communication used for railway, oil field, dock and army. ﹡Medical and electric equipments control. ﹡light and home appliances intelligent control. ﹡Security alarm and monitoring control. ﹡Check attendance system and positioning in coal mine. ﹡Car burglar proof, pressure detecting of the wheel, four-wheel orientation. ﹡Wireless POS in shops. ﹡GPS system. ﹡LED display in thruway and public places. ﹡Queue-management system in bank and government. ﹡Smart wireless PDA terminal for restaurant ordering system and voting system. ﹡Telemetry system. ============================================================== Features: 1. Ultra low power transmission with 100mW as maximal transmission power. 2. Requiring no any frequency, HAC-UEM transceivers work on ISM frequency band and carrier frequency is 433MHz. 3. High anti-interference and Low BER (Bit error Rate) Based on the Gaussian Frequency Shift Keying (GFSK) modulation, the high-efficiency forward error correction channel encoding technology is used to enhance data? resistance to both transient interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2. 4. Long Transmission Distance Within the visible range, when the height of antenna is higher than 2m and The Bit Error Rate (BER) is 10-3, the reliable transmission distances respectively is 2000m :1200bps, >1200m:9600bps and >400m:38400bps. 5. Transparent data transmission Transparent data interface used in transceivers is for meeting many standard or nonstandard user protocols. Any false data generated in air can be filtrated automatically (What has been received is exactly what has been transmitted). 6. Multi-channels HAC-UEM transceivers offer Multi-channels in one ISM frequency band satisfying various configuration of communication under user's demand at the same time and avoiding the interference by other devices in the same locale. (Channels setting is set via serial port command, please see the concrete method in Page6) 7. 1 port with three connection methods HAC-UEM transceivers provide 1 port with three connection ports: a UART interface of TTL level, a standard RS-232 port and a RS-485 port, but they are asynchronous, so only one port available once. 8. Intelligent data control and no any complicated transmission programs required Even for half duplex communication, no any excessive programs required. All RF system data transmission/reception and other On-the-Fly conversion and control are performed by HAC-UEM transceivers automatically. 9. Lower power consumption & Sleep function The receiving current is <45mA, the transmitting current is <130mA :100mW (60mA:10mW), and the sleeping current is <5uA(Sleep mode controlled by user). 10. High reliability, small and light By using monolithic radio-frequency integrated circuit and single-chip MCU, the transceivers have little peripheral circuits, high reliability, and low failure rate. 11. More options of configurable antennas for user different applications. ============================================================== Specification: Modulation mode: GFSK (Gaussian Frequency Shift Keying) Working frequency: 429~438MHz (402~470MHz available for customization) Interface data format: 8E1/8N1/8O1 Transmission power: 100mW or 20dBm (10mW~100mW available for special request) Receiving sensitivity: -122dBm: UEM12 / -118dBm: UEM / -102dBm: UEM384 RF data rate : 1200/2400/4800/9600/19200/38400bps (must be validated before leaving factory) Interface baud rate : 1200/2400/4800/9600/19200/38400bps (optional) Humidity : 10%~90% relative humidity without condensation Temperature : -10°C~60°C / -35°C~75°C Power supply : +4.75 ~ 5.25VDC ( 3V optional) Transmitting current : ≤130mA :100mW, ≤60mA:10mW(optional) Receiving current : ≤45mA Sleeping current : ≤5uA Channel bandwidth : 12.5KHz -UEM12 / 25KHz -UEM24 / 50KHz-UEM48 / 50KHz-UEM96 / 100KHz-UEM192 / 200KHz-UEM384 Adjacent Channel Inhibition Ratio : ≥65dB Mirror Inhibition Ratio : ≥80dB Obstructed : ≥80dB Dimension : 47.0mm*28.0mm*7.0mm (without antenna base) Weight : 25g (without antenna base)
