About JZ861
JZ861, a Mini power wireless module, is used as the wireless data transmission in short distance.
With the characteristics of small size, light weight, low power consumption, good stability and reliability,
it can provide bidirectional data transmission, test and control for users.
It is used for Wireless meter reading, such as water meter, electric meter and gas meter, parking meter,
intellective card, electronic weighing apparatus, meter for checking attendance, queue wireless meter, building
control, shipping company control, alarm system, intelligent equipment, Automatic data collecting system;
Industrial remote control and remote test building automation, safety and security, powerhouse equipment
wireless monitor, entrance control system, etc.
If necessary, we can provide USB interface to make it easy to settle the question of Power Supply for
Mini computer and PC users.
JZ861 Feature
1.Low power transmission
The transmission power ＜10mW, Receiving sensitivity: -110dbm
Size: 38mm*25mm*6mm.
2. Low power consumption
Receiving current<10mA，transmission current<35mA，sleeping current (the user should asked for it before
order ) <15uA.
3. ISM frequency band, not requiring on application of frequency point
Carrier frequency: 428---433MHz, also capable of 868/915MHz.
4. High anti-jamming 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.
5. Long transmission distance
Within the range of visibility, the reliable transmission distance is（BER=10-3/1200bps）>150m when the
antenna height is greater than 1m (BER=10-3/9600bps).
6. Transparent data transmission
Transparent data interface is offered, which can be fit for nonstandard user protocol. Any false data
generated in the air can be filtrated automatically (What has been received is exactly what has been
transmitted). Receiving and dispatching switching time<10ms.
7. Multi-channels and Multi-speeds
The JZ861 module provides 8 channels to meet many kinds of communication combination mode of the
users. The JZ861 Module can provide many kinds of correspondence baudrate such as 1200bps, 2400bps,
4800bps, 9600bps, 19200bps and so on.
The wireless transmission speed and the connection baudrate are proportional, to satisfies the customer
equipment of different baudrate.
