Detailed Product Description

Technical specification of JZ873:Data rf module

Features:

1. Low Power consumption and receiving sensitivity
Transmission power <5W, TX current<360mA, RX current<45mA, sleeping current <0.1uA.
High receiving sensitivity: -123dbm.
2. Saving power model
JZ873 have three Saving power models: awaken from Hardware, awaken from COM Port, awaken from Air;
3. IO attemper function
JZ873 have 2 on-off input ports,2 on-off output ports ,user can control remotely terminal without developing ;
4. Modulation mode and Frequency 
Modulation mode: GFSK, Frequency: 433MHZ. Also, 868mhz and 915mhz is possible.
5. High anti- interference and low BER(Bit error Rate)
Based on the GFSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance datas 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.
6. Long transmission distance
Within the range of visibility, the reliable distance is >800m ().
7. 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 charge time for receiving and sending <10ms.ve 2 on-off input ports,2 on-off output ports ,user can control remotely terminal without developing ;
8. Multi- channel
The standard JZ873 configuration provides 16 channels to meet the multiple communication combination mode of the user.
9. 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 .
10. 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. JZ873 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 chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate.
12. Watchdog monitor
Watchdog monitors the inner function, it changes the traditional product structure and also improve the reliability of our modules.
