Parameter Setup
Double click UHFAPP.exe to enter the software, and connect with the device
through the serial port line. Select Mode to “SerialPort”, select COM to
according serial port on PC. Click “Open” to connect with the device,
initiation page is as follows: 
If RJ45 has been used as a connection, communication Mode needs to be selected
as “network” and input IP address and port number (default IP address is
192.168.99.202, Port is 8888.) Then click “Open” to connect PC and device.
After PC and device have been connected, the status page is as follows:
After the device has connected with the PC, the parameters on the interface
will be empty. Click “Get” on each option to collect device parameters.
Click “Set” on the page, user can adjust necessary parameters, some parameters
are default values.
Output power can be set in the range of 5 dBm to 30 dBm as the following
picture, after selecting the value, click the “Set” button. If “Save” has been
selected, current parameters will be saved after power off the device.
Set regions:
Set RFLink:
Set continuous wave:
There are two work modes that can be selected, “command mode” and “auto mode”.
Under “command mode”, the user could collect tag data in the “Read EPC” page,
click “Start” to send command to the device on PC, click “Stop” to stop
collecting tag data.
Under “auto mode”, the user could collect tag data in the “UDP-ReceiveEPC”
page, click “Start” to receive data, click “Stop” to stop receiving data.
After selecting “auto mode”, the device needs to be restarted. 
Set IP address and make sure PC and device have used in the same segment. For example, if the IP address of the PC is 192.168.1.109, the mask is 255.255.255.0, the device’s IP address can be set to 192.168.1.201, the port number doesn’t need to be changed. 
Set antenna connection, there are 4 I/O ports on device and have been marked
as ANT1, ANT2, ANT3, ANT4. The user needs to select the antenna which has been
connected and click “set”. 
Set the destination IP address and port number, destination IP address is the
IP address used for reading tag data under “auto mode”. 
Set FastID:
Set TagFocus:
Set protective temp. It means to set up the highest operating temperature of
the UHF module: 
Set EPC and TID:
Reset, click the “Reset” button to restore the device to the default value.
After reset, the user needs to click “Close” and “Open” to reconnect the
device. 
Set Buzzer, click “Open” to switch on the buzzer function, the device will

Set Gen2, this parameter needs to be adjusted by actual requirements.
Chapter 3 Read and Write EPC
Read EPC
Click “ReadEPC” in the menu to enter the EPC page, click “Start” to read tags,
click “Stop” to stop reading. The EPC, RSSI, Count number and ANT number
(antenna channel) will be recorded in the window as the following pic:
A user could enter data in “Filter” to filter EPC of special tags, the maximum
filter DL is 96 bits. User needs to setup data, initial address, data length
and click “Set”. After filtered data has been set, the device will read and
search for the tag which has been filtered.
For example: enter 16 01 in “Data”, initial address data length is 32(bit),
length is 16(bit), select EPC in “bank”, click “Set” and click “Start” to
start scanning tags which the address start at 16 01:
Read & Write Tags
Click “ReadWriteTag” to enter its page, TID area can be read-only, RESERVED,
EPC, and USER areas can be read and written.
Click one option in the “Read-write” window to enter tag reading mode, EPC
will be automatically copied into the “Data” block in the filter, the default
option is EPC reading, click “Read” to read 12 bytes of EPC area. 
For the “RESERVED” area, the user could read 4 words at maximum, previous 2
words are the password of KILL function, last 2 words are access passwords:
Read TID area:
Read USER area:
Data could be written in EPC, RESERVED, and USER areas, select according to areas and input initial address, length, input data into “Data” window and click “Write” to write data into according areas.
Lock UHF Tag
Click “Kill-Lock” in the main menu to enter the Tag locking function. For this
function, the user could execute the “Lock”, “Kill”, “Open”, “Permanent Open”,
and “Permanent Lock”, to execute the “Lock” function, the password is needed.

tag will be wasted permanently. 
UDP-ReceiveEPC
After auto mode has been selected, restart the device and select
UDPReceiveEPC, click “Open” to connect the device and select the IP address of
PC in the address column, click “Stop” to stop receiving UHF tag data. If the
user needs to escape auto work mode, “command mode” needs to be selected in
work mode.
Others
Click “UHF information” in the main menu to read the hardware version and firmware version, click “Temperature” to read the current temperature value of the UHF module.
