Detailed Description
SRWF-508, the low-power wireless transceiver data module is used as the wireless data transceiver in short-ranges, with the small size, weight and power consumption and good stability and reliability. Narrowband low power UHF wireless data transmitters and receivers with channel spacings as low as 25 kHz: it is mainly used as following show: *orienting the steel wheel *Queue management system *intellectual over-weight detecting system *home automation system * AMR Automatic Meter Reading * Wireless alarm and security systems * 433 / 868 and 915 MHz ISM/SRD band systems * Data radio can be used for Wireless conference voting system; * Radio modem can be used for Sports training & competition; * Wireless sensor Industrial wireless remote control and air conditioning remote controller; * Observation and predication of oil well and hydrological information; * Wireless RS232/RS485 conversion/connector; * Point to multi-point wireless network, wireless on-the-spot bus and automatic data collection system; Technical specification of SRWF-508: 1 We use GFSK/FSK Modulation mode and use the high- efficiency forward error correction channel encoding technology so our modules have High anti- interference and low BER(Bit error Rate) feature. 2. Transmission power is 30dbm (1W) 3. Transmit distance is 4500m 4. We use GFSK/FSK Modulation mode, Interface format: 8N1/8E1/8o1 user-defined 5. We have three Interface mode : UART TTL / RS-232 / RS-485. The details of how to connect the interface you can read the user manual. 6. Interface baud rate is 1200/2400/4800/9600/19200bps, you can only choose one of it when you buy it. 7. Offering a transparent data interface, it is suitable for any standard or non-standard user protocols; 8.Transmitting current <550mA,Receiving current <32mA,Sleeping current <30uA 9.Power supply +4.5~5.5VDC 10. Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. SRWF-508 will automatically, complete the other operations, such as transmission/receiving conversion in the air, control, etc. ShangHai TangRay Info_tech Co.,Ltd Website:www.51sunray.com Tel:+86-21-50275250-808 mobile phone: 86-21-15800926219 E_mail: sales@tangray.com or maryanne1225@gmail.com Fax:+86-21-50270187 MSN:maryanne851225@hotmail.com
