Feature

1.Power and receiving sensitivity
The most Transmission power of JZ875 is 2W or 1W, The use can set the power according to their request.
Power supply: 5V. TX current<1.5A, RX current<50m A, Sleep power is <0.1mA.
2. Modulation mode and Frequency 
Modulation mode: GFSK, The Frequency can be choose from 400 to 470MHZ. The default is 428-436MHZ.
3. Working Temperature.
JZ875 is a true Industry Products, it can works from -35℃ to +80℃.
The stability of Frequency can achieve ±5PPM.
4. 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 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.
5. Long transmission distance
Within the range of visibility, the reliable distance is >3km to 10km when the antenna is higher than 3m.
6. 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 <20s.
7. Multi- channel
The standard JZ875 configuration provides 16 channels to meet the multiple communication combination mode of the user.
8. 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 .
9. 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. JZ875 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, it changes the traditional product structure and also improve the reliability of our modules.
