2.2 Parameter Setup

Double click UHFAPP.exe to enter software, and connect with device
through serial port line. Select Mode to “SerialPort”, select COM to
according serial port on PC. Click “Open” to connect with device,
initiation page is as follows:

If RJ45 has been used as 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 device has connected with PC, the parameters on 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 range of 5 dBm to 30 dBm as following

picture, after select value, click “Set” button. If “Save” has been
selected, current parameters will be saved after power off device.

Set regions:

11

Set RFLink:

Set continuous wave:

There are two work modes can be selected, “command mode” and

“auto mode”.

Under “command mode”, user could collect tag data in “Read EPC”
page, click “Start” to send command to device on PC, click “Stop” to

stop collecting tag data.

Under “auto mode”, user could collect tag data in “UDP-ReceiveEPC”

page, click “Start” to receive data, click “Stop” to stop receiving data.

After selecting “auto mode”, the device needs to be restarted.

12

Set IP address and make sure PC and device have used in same
segment. For example, if IP address of PC is 192.168.1.109, mask is

255.255.255.0, the device IP address can be set to 192.168.1.201,
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. User needs to select
antenna which has been connected and click “set”.

Set destination IP address and port number, destination IP address is
the IP address which used for reading tag data under “auto mode”.

13

Set FastID:

Set TagFocus:

Set protective temp. It means to setup highest operating temperature
of UHF module:

Set EPC and TID:

14

Reset, click “Reset” button to restore device to default value. After
reset, user needs to click “Close” and “Open” to reconnect the device.

Set Buzzer, click “Open” to switch on buzzer function, device will play

notification sound when reading tags.

Click “ReadEPC” in menu to enter 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 window as
following pic:

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:
