Features:

1.Power and receiving sensitivity
ÁThe transmission power is <100mW, Receiving sensitivity: -110dbm,
Transmission current<100mA, Receiving current<10mA
2. Modulation mode and Frequency 
¡¡Modulation mode: FSK, Frequency: 433mhz. Also capable of 315mhz, 868mhz and 915mhz.
3. High anti- interference and low BER(Bit error Rate)
¡¡Based on the FSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance data¡s resistance to both burst 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 range of visibility, the reliable distance is¡BER=10-3/1200bps¨ >500m when the antenna is higher than 200m (BER=10-3/9600bps).
5. Transparent data transmission
©¡Transparent data interface is offered to suit any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted). The change time between receiving and sending is <10ms.
6. Multi- channel
¡¡The standard JZ864 configuration provides 8 channels to meet the multiple communication combination mode of the user.
7. High speed wireless communication and Large data buffer zone
¡¡When the RF baudrate is bigger than COM baudrate, allowing to transmit unlimited length data at one time, when the RF baudrate is smaller or equal to the COM¡s, allowing the transmission of 255 Bytes data .
8. Intelligent data control and the user doesn¯t need to prepare excessive programs
¯¡Even for semi duplex communication, the user doesn¡t need to prepare excessive programs, only receiving/transmitting the data from the interface. JZ864 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.
9. High reliability, small and light
¯Single chip radio - frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate.
10. Watchdog monitor
¡¡Watchdog monitors the inner function, it changes the traditional product structure and also improve the reliability of our modules.
11. JZ864 User interface
¡¡JZ864 provide USB interface.
User must install the USB driver before using it. After installing the driver, PC can build one virtual serial port, User¡s soft can operate the serial port.
12. Encapsulation Structure, dustproof, waterproof and static proof
¯¡Comprised by plastic DOS shell¡epoxy encapsulation¬dustproof , waterproof and static proof¬good anti-jamming.
