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.
