About HXJZ-873
HXJZ-873, the Low 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.
HXJZ-873 Feature
1.Ultra low power transmission
Transmission power :500mW, high receiving sensitivity: -123dbm , size: 58mm*38mm*10 mm.
2. Low power consumption
Receiving current<45mA，transmission current<360mA，sleeping current < 1mA.
3. Saving power model
HXJZ-873 have three saving power models: awaken from Hardware, awaken from COM Port, awaken from
air
(the user need to ask for it before place an order).
4.IO attemper function
HXJZ-873 have 2 on-off input ports, 2 on-off output ports.
5. ISM frequency band, not requiring on application of f requency point
Carrier frequency of 433MHz，also capable of 868/915MHz.
6. High anti-interference and low BER (Bit error Rate)
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.
7. Long transmission distance
Within the range of visibility, the reliable transmission distance is (BER=10-
3/1200bps)>3000m, (BER=10-3/9600bps)>2000m when the antenna height is greater than 3m (BER=10-
3/9600bps).
8. 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.
9. Multi-channel and speed
The standard HXJZ-873 configuration provides 16 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、
38400bps. The wireless transmission rate is direct ratio with baud rate of interface to meet user’s equipment
requirement.
