Features:
1. Low Power consumption and receivingsensitivity
Transmission power 0.5W, TX current<360mA, RX current<45mA,sleeping current <0.1uA.
High receiving sensitivity: -121dbm.
2. Saving power model
JZ872 have three Saving power models: awaken from Hardware, awakenfrom COM Port, awaken from Air;
3. IO attemper function
JZ872 have 2 on-off input ports,2 on-off output ports ,user cancontrol remotely terminal without developing ;
4. Modulation mode and Frequency
Modulation mode: GFSK, Frequency: 433MHZ. Also, 868mhz and 915mhzis possible.
5. High anti- interference and low BER(Bit errorRate)
based on the GFSK modulation mode, the high- efficiency forwarderror correction channel encoding technology is used to enhancedatas resistance to both burst interference and random interferenceand the actual bit error rate of 10-5 ~ 10-6 can be achieved whenchannel bit error rate is 10-2.
6. Long transmission distance
Within the range of visibility, the reliable distance is >2000m().
7. Transparent data transmission
Transparent data interface is offered to suit any standard ornonstandard user protocol. Any false data generated in the air canbe filtrated automatically (What has been received is exactly whathas been transmitted). The charge time for receiving and sending<10ms.ve 2 on-off input ports,2 on-off output ports ,user cancontrol remotely terminal without developing ;
8. Multi- channel
The standard JZ872 configuration provides 16 channels to meet themultiple communication combination mode of the user.
9. High speed wireless communication and Large data bufferzone
When the RF baudrate is bigger than COM baudrate,allowing to transmit unlimited length data at one time, when the RFbaudrate is smaller or equal to the COMs, allowing the transmissionof 255 Bytes data .
10. Intelligent data control and the user doesnt need toprepare excessive programs
Even for semi duplex communication, the user doesnt need to prepareexcessive programs, only receiving/transmitting the data from theinterface. JZ872 will complete the other operations automatically,such as transmission/receiving conversion in the air, control,etc.
11. High reliability, small and light
Single chip radio - frequency integrated circuit and single chipMCU are used for lessened peripheral circuits, high reliability,and low failure rate.
12. Watchdog monitor
Watchdog monitors the inner function, it changes the traditionalproduct structure and also improve the reliability of ourmodules.
