JZ874 USB Data Transceiver

Users can choose various antenna setting project and antenna according to users different need to achieve a optimal effect.

12. Antenna choose

Watchdog monitors the inner function, so that change the traditional product structure and improve the product reliability.

11. Watchdog monitor

peripheral circuits, high reliability, and low failure rate.

Single chip radio- frequency integrated circuit and single chip MCU are used for lessened

10. High reliability, small and light

Even for semi duplex communication, the user doesnt need to prepare excessive programs, only receiving/transmitting the data from the interface. JZ874 will automatically complete the other operations, such as transmission/receiving conversion in the air, control, etc.

9. Intelligent data control and the user doesnt need to prepare excessive programs

When the speed rate in the air is quicker than interfaces, allowing to transmit unlimited length data at one time, when the speed rate is slower or equal the interfaces, allowing the transmission of 255 Bytes long data frames at one time for more flexible programming by users.

8. High speed wireless communication and Large data buffer

The standard JZ874 configuration provides 8 channels. to meet the multiple communication combination mode of the users. It has baud rate to be chosen such as 1200bps2400bps4800bps9600bps19200bps38400bps. The  wireless transmission rate is direct ratio with baud rate of interface to meet users equipment requirement.

7. Multi-channel and speed

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.

6. Transparent data transmission

Within the range of visibility, the reliable transmission distance isBER=10-3/1200bps>3000m(JZ874B) , >800m (JZ874A),when the antenna height is greater than 3m (BER=10-3/9600bps).

5. Long transmission distance

Based on the GFSK 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. High anti-interference and low BER (Bit error Rate)

Carrier frequency of 428---433MHz,also capable of 868/915MHz.

3. ISM frequency band, not requiring on application of frequency point

Receiving current<45mA, transmission current<360mA(JZ874B),. <100mA(JZ874A),

2. Low power consumption

Size: 70mm*45mm*19mm

Transmission power: 500mW(JZ874B), 100mW(JZ874A);High receiving sensitivity: -123dbm,
