JZ861 Mini Power Wireless Module
JZ861 module is built with the PCB antenna wireless module, the use of ISM frequency band,
without application frequency; can be set to four communication channels, transmit power of
10mW (10dB), high receiver sensitivity-110dbm, size 38mm * 25mm * 6mm (with PCB antenna),
the industry's smallest PCB board antenna with a wireless module, is very convenient for users to
do the embedded wireless systems.
JZ861 the use of transparent transmission, in order to ensure the reliability and stability of the
user's system, plus the transmission checksum or CRC checksum error detection mode, the error
data retransmission. Transceiver module buffer of 512bytes, means that users can be in any state
512bytes of data transfer 1, when the speed is greater than the serial port is set to air rate, is
theoretically unlimited length can send information packets, but does not recommend users to send
long data packets, the proposed length of each packet data between 60 ~ 100B, generally not
longer than the 120B, and recommended user program using the ARQ mode, the error data packets
retransmission. As follows:
If the actual error rate 10-4, users need to send 1KB about 10000bit information, if the 1KB
data as a packet, sent at least theoretically, there will be a data error in the receiver, then the 1KB
data can never be received correctly. If it is divided into 10 packages, each package 100B, then
send 10 packets, the packets according to a probability of only 1 error, the error in the form of a
packet retransmission by ARQ 1, although it took more than 1 packet and the efficiency decreased
by about 10%, but it can guarantee all the information is correctly received.
In the work on, JZ861 There are two ways of working, first for the conventional model, which
Module is powered On, is in receive mode; you also can be sending data. The second is sleep
mode, that is, through the power module in a dormant state, to be awakened by the user's foot
control module, the module can send and receive data.
In the application of JZ861 module, the module uses a wide voltage range, but also be divided
into two kinds of voltage, the first for the 5V power supply module, also known as conventional
modules, voltage DC 3.3-5.5V. The second is 3V power supply modules, custom module for the
user, the voltage of DC 2.7-3.3V; users in the use of power to DC power supply, the current must

Module with customer equipment connections
Note: JZ861 did not sleep in the state, the module of the SLE feet must be vacant. In the
sleep state when the module must be low, the module can send and receive data.
Module with PC connections
Note: As JZ861 mode TTL interface module, so the PC must be added to connect the TTL to
RS232 converter, and converter must supply DC 5V of electricity.

For software testing and change parameters
A, between the JZ861 module and connect a PC RS-232 to TTL adapter, and plug in the power,
select the serial port used.
B, the radio detection, when the check to the station (the software will prompt detection success),
you can read or change a single parameter.
C, change parameters, when you select a parameter you want to set, after set up to read again, to
see the parameters of the module is not what you want.
Note: Two or more modules to communicate, then the frequency of the station modules and air rate
must be consistent.
Module to communicate with user equipment, the module's serial port parameters and user
settings must be consistent.

Communicated Module
JZ861 ultra-compact wireless module with all the JZ86 series of models to communicate with each
other. Communications as long as you pay attention to the following:
A, select all the modules to communicate with each other for 2 to 4 channels of a channel.
B, you have the same communication module of the air rate.
C, the communication module, power supply, interface connection is connected.
Sleep Mode
JZ861 divided into dormancy release version with no sleep.JZ861 sleep after the current is 15uA.
JZ861 hibernation wake-up mode for the hardware. Wake is the fifth through the interface
hardware input pin high to sleep, wake-up input low.
If the user has a sleep function JZ861, but do not want to use the hibernate feature, available
through JZ861 pin 5 to ground, then achieve.
Details as followings
Module in the working state to sleep state, it is necessary to SLE pin from low to high, if the
module is idle (no transmit / receive data) MCU to sleep within about 1ms; If you are in the
collection and development data, the data will be processed the frame side to sleep.
Module in sleep state to work state, it is necessary to SLE pin from high to low, MCU is working
on several ms to enter into the state, but in order to send data to the stability of the user side should
be more than 60ms latency available for data transmission.

Transform on transceiver and receiver
End user devices receiving the data sent by the module, and then transferred to the data center must have
sent more than 1ms delay.
From Module A(transmit) to Module B(receive)
When the user is doing data transfer, the data must take into account the delay module, in
order to ensure the reliability of wireless transmission, the company added the module FEC
(forward error), and other encoding rules. Then from A to B module module, in the middle of the
transmission of data with different baud rates for the delay, in the following table:
