About HXJZ-862
HXJZ-862, the mini power wireless module Enveloped with Epoxy, is used as the wireless data
transmission
in short distance.
With the characteristics of small size, 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.
HXJZ-862 Features:
1. Low power transmission
The transmission power is ＜100mW, Receiving sensitivity: -110dbm,
Size: 47mm*33mm*14mm.
2. Low power consumption
Receiving current<11mA, transmission current<100mA.
3. ISM frequency band, not need to require frequency point
Carrier frequency of 428---433MHz，also can provide 868/915MHz .
4. High anti-jamming and low BER (Bit er ror 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 is higher than 2m (BER=10-3/9600bps).
6. Transparent data transmission
Transparent data interface is offered, which can be fit for any standard or nonstandard user’s 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
And The HXJZ-862 module standard disposition provides 8 channels to meet many kinds of
correspondent combination mode of the users. The HXJZ-862 Module may provide many kinds of
correspondence budrate 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.
