Feature of JZ882 Middle Power Data RF Module:
1. Power and receiving sensitivity
The transmission power is <500mW, Receiving sensitivity: -120dbm,
Transmission current<400mA, Receiving current<60mA, sleeping current <100uA.
2. Modulation mode and Frequency
Modulation mode: FSK, Frequency: 490MHz. Also capable of 160/230/315MHz.
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>1500m, (BER=10-3/1200bps)>2500m when the antenna is higher than 2m.
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 JZ882 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. JZ882 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.

10. 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.
11. Watchdog monitor
Watchdog monitors the inner function, so it can change the traditional product structure and also improve the reliability of our modules.
