About HXJZ-882

HXJZ-882, the Micro power wireless module, is used as the wireless data transmission in short distance.
With the small size, weight and power consumption and good stability and reliability, it has the function

of bi-directional data sign transmission, test and control.

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 on work 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. It provide the USB power
interface to be convenient
for the mini computer and PC users if necessary.

JZ8882 Feature

1.Ultra low power transmission

Transmission power ＜500mW, high receiving sensitivity: -120dbm;
Size: 63mm*43mm*15 mm

2. Low power consumption

Receiving current<60mA, transmission current<400mA, current<100Ua.

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

Carrier frequency of 490MHz，also capable of 160/230/315MHz

4. High anti-interference 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）
>1500m,

（BER=10-3/1200bps）>2500m when the antenna height is greater than 2m (BER=10-3/9600bps).

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 charge time for receiving and sending <20ms.

7. Multi-channel and speed

The standard HXJZ-882 configuration provides 8 channels to meet the multiple communication
combination mode of the users. It has baud rate to be chosen such as 1200bps、2400bps、4800bps、9600bps、19200bps.
The

wireless transmission rate is direct ratio with baud rate of interface to meet user’s equipment requirement.

8. High speed wireless communication and large data buffer

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

9. Intelligent data cont rol 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. HXJZ-882 will automatically complete the
other operations,

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, so that change the traditional product structure and
improve the product reliability.
