3）Using antenna cable to connect with external antenna
Such a connecting method is suitable for the products with the enclosure that has strong
shield for wireless signal. The module has been soldered with IPX antenna base, at the same
time, it needs to cut down the PCB antenna and lead the signal to IPX antenna base. If the IPX
antenna base isn’t needed, it can solder antenna cable directly. In this way, the connecting
method is much firmer, but it is not suitable for transportation and assembly, because the pad
for soldering antenna cable is easy to fall off if there is a force during the process of
transportation and assembly.
A Using antenna cable with two ends connector called KX-IPEX-10G1-SMA-F to connect
with an 10cm external folding helical antenna called HAC-Antenna-LX2400-10-ZSMA-M。

V. Working Mode of HAC-Ubee Wireless Module
5.1. Working Mode of HAC-Ubee Wireless Module
There are three working modes for HAC-Ubee. They are: Transparent Mode, API Mode, AT
Command Mode.
5.1.1 Transparent Mode
By default, Modules operate in Transparent Mode. When operating in this mode, the modules act as
a serial line replacement - all UART data received through the RXD pin is queued up for RF
transmission. When RF data is received, the data is sent out the TXD pin.
z No serial characters are received for the amount of time determined.
z The maximum number of characters that will fit in an RF packet (85) is received.
Serial-to-RF Packetization
Data is buffered in the RXD buffer until one of the following causes the data to be packetized and
transmitted: If the module cannot immediately transmit (for instance, if it is already receiving RF
data), the serial data is stored in the RXD Buffer. The data is packetized and sent at timeout or when
85 bytes (maximum packet size) are received.
5.1.2 API Mode
API (Application Programming Interface) Operation is an alternative to the default Transparent
Operation. The frame-based API extends the level to which a host application can interact with the
networking capabilities of the module.
When in API mode, all data entering and leaving the module is contained in frames that define
operations or events within the module.
Transmit Data Frames (received through the RXD pin (pin 3)) include:
• RF Transmit Data Frame
• Command Frame (equivalent to AT commands)
Receive Data Frames (sent out the TXD pin (pin 2)) include:
• RF-received data frame
• Command response
• Event notifications such as reset, associate, disassociate, etc.
The API provides alternative means of configuring modules and routing data at the host application
layer. A host application can send data frames to the module that contain address and payload
information instead of using command mode to modify addresses. The module will send data
frames to the application containing status packets; as well as source, RSSI and payload information
from received data packets. The API operation option facilitates many operations such as the
examples cited below:

• Transmitting data to multiple destinations without entering Command Mode
• Receive success/failure status of each transmitted RF packet
• Identify the source address of each received packet
* How to let the module work under the API mode after power up?
User can use AT command to enter the API mode. The setup steps are shown as follow:
Enter the AT Command page
Input the 3-character command sequence “+++” and wait for the reply “OK” from module.
Input “ATAP 1<CR>” command, the module will reply “OK”. It is used to set the module working
under API mode.
Input “ATWR<CR>” command, the module will reply “OK”. It is used to save the setting. So the
module will enter API mode automatically when restart the module next time.
Input “ATCN<CR>” command to exit from the AT Command mode. Now, the module works under
the API mode. Even power up the module again, it still enters the API mode directly.
5.1.3 AT Command Mode
To modify or read RF Module parameters, the module must first enter into Command Mode - a state
in which incoming characters are interpreted as commands. Two Command Mode options are
supported: AT Command Mode [refer to section below] and API Command Mode
Send the 3-character command sequence “+++” and observe guard times before and after the
command characters.
NOTE: Failure to enter AT Command Mode is most commonly due to baud rate mismatch. Ensure
the ‘Baud’ setting on the “PC Settings” tab matches the interface data rate of the RF module. By
default, the BD parameter = 5 (38400 bps).
To read a parameter value stored in the RF module’s register, omit the parameter field.
The preceding example would change the RF module Channel to “0x0B”. To store the new value to
non-volatile (long term) memory, subsequently send the WR (Write) command.
For modified parameter values to persist in the module’s registry after a reset, changes must be
saved to non-volatile memory using the WR (Write) Command. Otherwise, parameters are restored
to previously saved values after the module is reset.
System Response: When a command is sent to the module, the module will parse and execute the

command. Upon successful execution of a command, the module returns an “OK” message. If
execution of a command results in an error, the module returns an “ERROR” message.
NOTE: Some parameters will validate at once after setting, but some parameters will validate after
restart the module. So please read every AT command very carefully.
To Exit AT Command Mode:
Send the ATCN (Exit Command Mode) command (followed by a carriage return). [OR]
If no valid AT Commands are received within 10 seconds.
5.1.4 How to select the working mode
The default setting in the factory is transparent working mode.
1. Under the transparent mode, input 3-character command sequence “+++” from serial port, it will
change for the AT Command mode.
2. When you select the transparent working mode (ATAP 0), inputting “ATCN” command can exit
from the AT Command mode and enter the transparent mode. Or when you select the transparent
working mode (ATAP 0), if there is no input in 10 seconds, the module will exit from the AT
Command mode and enter the transparent mode.
3. When you select the API working mode (ATAP 1), inputting “ATCN” command can exit from the
AT Command mode and enter the API mode. Or when you select the API working mode (ATAP 1),
if there is no input in 10 seconds, the module will exit from the AT Command mode and enter the
API mode.
4. Under the API mode, input 3-character command sequence “+++” will let the module switch to
AT Command mode.
5. Under API mode, when using AT Command to setup transparent mode (ATAP 0), the module will

non-volatile memory after modifying interface data rates. And Modified interface data rates do not
take effect until restart the module next time. When parameters 1-7 are sent to the module, the
respective interface data rates are used (as shown in the table on the right). The RF data rate is not
affected by the BD parameter. We recommend that users don’t select too low interface data rate, or
it will cause the serial port data communication overflow.

Input “ATFR<CR> command, the module will restart at once.
5.2.3 CH
<Networking {Addressing}> The CH command is used to set/read the operating channel on which
RF connections are made between RF modules. The channel is one of three addressing options
available to the module. The other options are the PAN ID (ID command) and destination addresses
(DL, DH & DS commands). In order for modules to communicate with each other, the modules
must share the same channel number. Different channels can be used to prevent modules in one
network from listening to trans-missions of another. Adjacent channel rejection is 23 dB. The
module uses channel numbers of the 802.15.4 standard. Center Frequency = 2.405 + (CH - 11d) * 5
MHz (d = decimal)
To validate setting parameters, when setting the channel, at the same time, using the RN command
to setup the module as that reset the network after restart next time, then write the settings to the
non-volatile memory. In this way, the module will work on the new channel after restart the
module next time.

parameter, it defines the destination address used for transmission. An module will only
communicate with other modules having the same channel (CH parameter), PAN ID (ID parameter)
and destination address (DH + DL parameters). 0x000000000000FFFF (DL concatenated to DH) is
the broadcast address for the PAN.

for a module, it can be set as 0x00-0xFFFE. If the PAN ID of module is 0xFFFF, and there will
be different results according to different module types. If it is Coordinator, when power up, it
will select one value from 0x00-0xFFFE as its PAN ID in random. If it is Router or EndDevice,
when power up, they will search the PAN ID of Zigbee network that is nearby, assign the same
value for PAN ID and try to enter the Zigbee network. When there are some Zigbee networks
around, they will select the network with best RSSI value.
When the PAN ID is 0xFFFF, the actual PAN ID value after enter the network can be read by

5.3 API Operation
By default, RF Modules act as a serial line replacement (Transparent Operation) - all UART data
received through the RXD pin is queued up for RF transmission. When the module receives an RF
packet, the data is sent out the TXD pin with no additional information.
Inherent to Transparent Operation are the following behaviors:
• If module parameter registers are to be set or queried, a special operation is required for
transitioning the module into Command Mode.
• In point-to-multipoint systems, the application must send extra information so that the receiving
module(s) can distinguish between data coming from different remotes.
As an alternative to the default Transparent Operation, API (Application Programming Interface)
Operations are available. API operation requires that communication with the module be done

through a structured interface (data is communicated in frames in a defined order). The API
specifies how commands, command responses and module status messages are sent and received
from the module using a UART Data Frame.
5.3.1 API Frame Specifications
API mode can be enabled using the AP (API Enable) command. Use the following AP parameter
values to configure the module to operate in a particular mode:
• AP = 0 (default): Transparent Operation (UART Serial line replacement) API modes are disabled.
• AP = 1: API Operation
Any data received prior to the start delimiter is silently discarded. If the frame is not received
correctly or if the checksum fails, the data is silently discarded.
API Operation (AP parameter = 1)
When this API mode is enabled (AP = 1), the UART data frame structure is defined as follows:
Figure UART Data Frame Structure:
MSB = Most Significant Byte, LSB = Least Significant Byte
Checksum
To test data integrity, a checksum is calculated and verified.
To calculate: Not including frame delimiters and length, add all bytes keeping only the lowest 8
bits of the result and subtract from 0xFF.
To verify: Add all bytes (include checksum, but not the delimiter and length). If the checksum is
correct, the sum will equal 0xFF.
5.3.2 API Types
Frame data of the UART data frame forms an API-specific structure as follows:

5.4.1 How to broadcast transmission?

First users need to note that the broadcast is restricted to avoid the broadcast storm in the network.
In a Zigbee network, all the broadcast items for all the nodes should not be more than 9 items
(default value) in 3 seconds. If it exceeds the default value, the network will shield broadcast
automatically.
Broadcast under transparent mode
Under the transparent mode, if the type of destination address which can be set by ATDT command
is 16-bit address, set the 16-bit destination address as 0xFFFF which can be set by ATDS command,.
If the type of destination address is 64-bit address, set the high 32-bit destination address as
0x00000000 which can be set by ATDH command. And set the low 32-bit destination address as
0x0000FFFF which can be set by ATDL. In this way, under the transparent mode, all the data input
from the serial port of module can be transmitted by broadcast.
Broadcast under the API mode
Under the API mode, if users want to send data by 64-bit destination address, users only need to set
the address as 0x000000000000FFFF. If by 16-bit destination address, users need to set the address
as 0xFFFF. In this way, under the API mode, data can be transmitted by broadcast.
When the module transmits data by broadcast, all the other online modules in the network can
receive the data.
5.4.2 How to know a module that has been in the network?
Read the short address or 16-bit address (AT Command is ATMY.) can confirm the module
whether it is in the network. If its short address is 0xFFFE, it means it is not in the network. If its
short address is less than 0xFFFE, it means it is in the network.
Need to know that the Coordinator is always in the network. For one module, if the module has
been in a network, it will always be in the network, even the module has been restarted again, and
the short address can not be changed. Only when using the ATRN command to initialize the
network, the module will lose the network.
5.4.3 How to make the module work under the API mode after power up?
Users can use AT command to make the module enter API mode:
Enter the AT Command page of HAC Studio.
Input 3-character command sequence “+++” and wait the module returns “OK”
Input “ATAP 1<CR>” command, the module returns “OK”, it is used to setup the module work
under the API mode.
Input “ATWR <CR>” command, the module returns “OK”, it is used to save the setting to keep the

34 -
working mode as API mode after restart the module.
Input “ATCN <CR>” to exit from the AT Command mode. Now, the module is working on the API
mode. Even restart the module, it also enters the API mode directly.
5.4.4 Keep the 64-bit address of every module in the network has a unique address
In a Zigbee network, the 64-bit address of every module should be unique to ensure that every
module works normally in the network. If there are two modules which have the same 64-bit
address in the Zigbee network, it will cause some communication chaos. This is very important.
The 64-bit address has been set by the chip manufactory of the module in the factory. The chip
manufacture ensures the unique 64-bit address for each chip. So, we don’t recommend change the
64-bit address.
Except change 64-bit address intentionally can make that two modules have the same 64-bit address,
there are some other involuntary operations that can cause this phenomena. For example, when you
are using “Setup (API)” page of HAC-Studio setting software to setup, you read the setting of one
module, after change the module, you don’t read the 64-bit address again and setup the module
directly. In this way, the 64-bit address of last module is still in the page, so it will be written into
the new module. So it will cause two modules have the same 64-bit address.
VI. Assistant Software
We offer a upper software called HAC Studio to help users to test, evaluate and setup the
HAC-Ubee module. There are 5 parts in total.
"COM Setup" page is used to setup the computer’s serial port. Only when the settings of serial port
are correct, the software can communicate with the module normally.
"AT Command" page is used to input and output AT Command.
"Range Test" is used for the communication test of module, it only can run under the API mode
(AP=1).
"Setup" is used to setup the module. But the most important is that some settings can affect the
working state and performance of the module. "Setup" only can run under the API mode (AP=1).
"Help" is the help for software. Before using the software, please read the “Help” at first.

2. The sort of Zigbee module
Our ZigBee module is based on ZigBee protocol stack of TI company. According to different
functions in the network, module can be divided into three types, one is Coordinator, another one is
Router, the rest one is end device. The appearance and interface of three types are the same. Users
can distinguish them by label or by the upper software.
Picture Module Label
3. Zigbee Network
One Zigbee network only have one Coordinator, it is useed for the establishment of the network.
Only after Coordinator has been electrified for a few seconds, the network can be startup.
Coordinator is the first node in the network. Then Router can connect with Coordinator and enter
into the network. At the same time, Router in the network allows the other Router enter the network
by connecting with it. Any two nodes in the network can do point-to-point communication. At the
same time, any node can broadcast to the other nodes.
Whether a module can enter the network depends on whether it has node that has enter network in
its communication distance. If the distance between the module and its nearest node in the network
is more than its communication distance (seen in the module specification), and the node will not
communicate with any nodes in the network.
The establishment of ZigBee network can finish automatically after the module has been electrified,
User doesn’t need to operate. The order for the module’s power doesn’t seem particularly important.
After Coordinator has been electrified, ZigBee network can be built. Once a Router has entered the
network, even if the Coordinator’s power is off, the network can also work normally.
The networking for Coordinator needs to search the suitable channel. And Router enter the network
also need to search channel and network and connect. It needs some time to deal with these
processes. For Coordinator and Router, once the module enters the network, except initializing the
network, or the module will still in the network.
All modules in one network should have the same PAN ID and channel.

4. The 64-bit address and 16-bit address of module
The 64-bit address has been set by the chip manufactory of the module in the factory. The chip
manufacture ensures the unique 64-bit address for each chip. Before entering one Zigbee network,
its 16-bit address is 0xFFFE, it is unmeaning. Once the module enters the Zigbee network, it will
get a 16-bit address that is less than 0xFFFE. In this network, the 16-bit address is unique, except
reset the network, or 16-bit address will always belong to this module. The 16-bit address of
Coordinator in the network is fixed, it is always 0x0000.
