Feature of JZ883 Middle Power Data RF Module:

1.Power and receiving sensitivity The transmission power is <500mW, Receiving sensitivity: -122dbm,Transmitting current<360mA, Receiving current<45mA, sleeping current <1mA.2. Modulation mode and Frequency Modulation mode: GFSK, Frequency: 490mhz. Also capable of 160/230/315MHz.3. High anti- interference and low BER(Bit error Rate)Based on the FSK modulation mode, it adopts the efficient communication protocol. 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 height is greater 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- channelThe standard JZ883 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 COMs, allowing the transmission of 255 Bytes data. 8. Intelligent data control and the user doesnt need to prepare excessive programs Even for semi duplex communication, the user doesnt need to prepare excessive programs, only receiving/transmitting the data from the interface. JZ883 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, so it can change the traditional product structure and also improve the reliability of our modules.
