7. User Instruction

7.1.Network role and notice

No.

Description

1

Module uses Zigbee ad hoc networking, consisting of one coordinator and random other devices(routers and
end-devices)

2

It has self-organization, self-routing and network multi-hopping function (By default the network depth is 5, there
are 20 son nodes and 6 son router nodes in total)

3

The father node device (coordinator and router) can save data for the end-devices in sleep. The save time can be
set by the user (by default it is 30 seconds, ranging from 0 to 120 seconds).

4

Only the end device has the sleep function, sleeping within 250S, the user can set by themselves, the default 0 (with
sleep mode off).
Note: The recommended sleep time must be less than the data storage time of father node , otherwise it will affect
the data reception.

5

In network communication Short Address communication is used.
Note: The short address is randomly distributed when the device joins the network, the long address of MacAddress
is the only fixed one, if the short address is unknown, the network Short Address can be found via corresponding
commands according to the MacAddress , and point to point communication is conducted.

6

Coordinator is unique in the network, the short address is 0000.

7

If unicast address is FFFF，FFFD，FFFC，then it corresponds to three broadcast mode.

8

When PANID is FFFF, it means automatic distribution. Networking can not be realized if PANID is different.

30

9

When network keys are not the same the network can not be joined. The module network key of the module
remains open, the user can not get the correct air data via software packet capture .

10

All devices in the network have opened broadcast function. Multiple devices broadcasting at the same time or a
single device broadcasting at a higher frequency will lead to a serious network congestion. Please try to avoid this
situation.

11

When multicasting module does not need to join the group,but be directly multicasted to any group according to
communication usage guidance. After the multicast, the local group number will not change due to different
multicast number.

12

PWM function and sleep mode can not be used at the same time in network, please turn off the sleep mode before
turn on PWM function .

13

After sleep mode, it can be waked up via the serial port(UART).
Note: In the sleep state, the first frame of data waked up via UART is invalid.

14

In the Zigbee network, single package data transmission can not be too fast(recommended more than 1s), because
the data may be lost. (Note, it may cause network instability when the nodes is too many and transmission is too
fast )

Notes：see more in <Zigbee setting software instruction>

7.2.Network structure

The network structure of module is MESH network

MESH network topology network has a powerful function, the network can communicate via "multi-level hopping"; the

topology can also form a ver y complex network; network also has self-organization, self-healing function.

9. Note

1. Please keep the warranty card of the equipment which includes the factory number (and important technical

parameters) and is important for user's future maintenance and new equipment.

2. Transceiver during the warranty period, if the quality of the product itself rather than man-made damage or

lightning and other natural disasters caused by damage, enjoys free warranty; please do not repair by yourself, the
problem and please contact with our company when problem occurring, we offer the first-class after-sales service.

3. Please do not operate the transceiver in some flammable places such as coal mines or near explosive atmospheres

(such as detonators).

4. Please use the appropriate DC power supply, high frequency interference ability, small ripple, and enough load

capacity are required; it’s better to have over current, over voltage protection and lightning protection and other functions
to ensure that transceiver working properly.

5. Please do not use it in the working environment beyond the transceiver environmental characteristics, such as high

temperature, humidity, low temperature, strong electromagnetic fields or dust larger environment.

6. Please do not continuously keep transceiver to transmit in full capacity, or the transmitter might be damaged.

7. Please connect the ground with the external ground of the power supply (such as PC, PLC, etc.), otherwise it is easy

to burn out the communication interface; do not plug the interface with power supplying.

8. When testing, please connect the antenna or 50 Ω load, otherwise transceiver will be damaged easily ;the

distance from the antenna is better than 2 meters, so as to avoid harm, please do not touch the antenna when
transmitting.

9. Wireless data transceiver has different communication distance in different environments, communication distance

is influenced by temperature, humidity, obstacle density, obstacle volume and electromagnetic environment; in order to
ensure stable communication, it is recommended to reserve at least 50 % of the communication distance.

10. When communication distance is not perfect, it is recommended to improve the antenna quality and the

installation mode of the antenna. You can send mail to [e-mail] for support.

11. When choosing power supply, it is recommended to keep at least 50% current left and the ripple must not exceed

100mV.
