About HXJZ-863

HXJZ-863, the mini 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 bidirectional 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.

If necessary, we can provide USB interface to make it easy to settle the question of Power Supply for
Mini computer and PC users.

HXJZ-863 Features:

1.Ultra low power transmission

Transmission power is 100mW, high receiving sensitivity: -110dbm

Size: 44mm*27mm*8mm.

2.Low power consumption

Receiving current<11mA，transmission current<100mA，sleeping current (the user need to ask for it
when place an order) <10uA.

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

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

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） >500m 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 <10ms.

7. Multi-channel and speed

The HXJZ-863 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. The
RF baud rate is 1200bps、2400bps.

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

HXJZ-863 Mini Power Wireless Module User’s Manual

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 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. HXJZ-863 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.
