DTR900-FC Transceiver Module Spec
一、 SUMMARY
DTR900S－FC transceiver module adopt the most advanced
Europe " bluetooth technology " at present , adopt the
high-performance single IC radio frequency produced in digital
scientific and technological , 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. Suitable for traffic, meteorological phenomena ,
environmental data are gathered, intellectual district,
parking area vehicle managing, ammeter ,watch meter,gas meter
wireless read meter, ammeter ,watch meter,gas meter wireless
read meter etc.
二、 SPECIALITY
1．Mminiature power：transmit power 10mW---2W。
2. ISM frequency,no need licence，carry frequency
430-438MHz，also provide 315/868/915MHz。
3. High anti-interference ability: adopt high-efficient
forward correct error and check error by CRC,when the channel
signal 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. It is flexible and convenient to set up：can set up RF
frequency ,series rate ,product ID.
7. It is far to transmit the distance：the distance of
reliably transmit>（BER=10-3/1200bps），300~2000m。
8. RS232/RS485/TTL UART interface。
9. Low consumption and sleep function :receiving current
