（1） DTR920 Transceiver Ⅰ.SUMMARY DTR920 Wireless transceiver module adopt high-performance RF IC ,adopt high-efficient forward correct error by CRC , work steady and reliable while being at a high speed. Industry grades of standard, small and easy to install. Ⅱ.SPECIALITY 1．Miniature power: transmit power 70dBuv. 2. Carry frequency: 434MHz. 3. High anti-interference ability: adopt high-efficient forward correct error and check error by CRC, when the channel signals error code rates on the10 -2, can receive error code rates of actual mistake 10-5-10-6. 4. Transparent data transmission of half duplexing communication. 5. The wireless communication of high speed and big data buffering area. 6. Flexible set up：RF frequency ,series rate ,product ID. 7. Transmit distance： <600m。 8. interface：RS232，TTL，RS485 9. Low consumption and sleep function :receiving current <25mA ， transmitting current<35mA,sleep current<20uA （ baud rate=9600bps）. 10. DC Power:+5V 12. High dependability, industry standard.
