About HXJZ-871

HXJZ-871, 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 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.

Features:

1.Ultra low power transmission

The highest transmission power is 100mW, high receiving sensitivity: -121dbm,

Size: 44mm*27mm*8mm

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

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

3. 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.

4. Long transmission distance

Within the range of visibility, the reliable transmission distance is(BER=10-3/1200bps)

>800m when the

antenna is higher than 3M.

5. 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). The change time for receiving and sending <10ms.

6. Multi-channel and speed

The HXJZ-871 provides 8 channels to meet the multiple communication combination mode of the users.
The

JZ861 Module can provide many kinds of correspondence baud rate such as 1200bps, 2400bps,
4800bps,

9600bps, 19200bps and 38400bps.

The wireless transmission speed and the connection baud rate are proportional, to satisfies the customer

equipment of different baud rate.

7. High speed wireless communication and Large data buffer

When the RF baud rate is bigger than the COM baud rate, allowing to transmit unlimited data at one time,

and when the RF baud rate is smaller than or was equal to the COM baud rate ,may transmit 255 bytes data

8. 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-871 will automatically

complete the other operations,
