2.1 Initial Use
2.1.1 Step 1: Connect The Reader to PC via USB or Serial Port
Method NO.1: You can connect the reader to your PC via USB Cable.
Next, please switch the DIP to the position as illustrated below:
Method NO.2: You can also connect the reader to PC via RS-232 serial port
Next, please switch the DIP to the position as illustrated below:

YR903 UHF RFID Evaluation Kit User Manual V1.1
When the indicator light on and sound of a short beep, reader is ready.
Note: Driver will be installed automatically when reader is connected to PC for the first time. But
some computers may fail. In this case, please install driver manually. (please see: Installing
Driver at page 21).
2.1.2 Step 4: Operating Reader via Demo
Put the files that named UHFDemo.exe, reader.dll, customControl.dll into a same folder, and double-
click UHFDemo.exe to run the software.
1. Open the software and it will shows as below:
2. Please select RS232 as Connection if the reader is connected via RS -232 port, or select USB as
Connection if the reader is connected via USB. Choose the corresponding Serial Port and Baudrate
(default baudrate is 115200). As illustrated below:
3. Click Connect , if it succeeds, the Operation History will display as below:

YR903 UHF RFID Evaluation Kit User Manual V1.1
4. Text communication with the reader:
Click on Get in Firmware Version or in Reader Identifier, the following screen displays:
Now the reader has been connected to PC successfully.
2.2 Setting RF Parameter
After connecting the reader with PC, we need to set some basic RF parameters: RF Output Power & RF
Spectrum. Please select RF Setup as illustrated below:
2.2.1 Setting RF Output Power
RF Output Power is the strength of RF output signal from antenna port whose unit is dBm.
The output power range is 0 - 26dBm. When this setting completes, it will be saved in the reader
automatically even if the power is cut off. The default output power is 26dBm.
2.2.2 Setting RF Spectrum
Set the RF spectrum manually.
Please defer to Frequency parameter tablet in Communication protocol for more information about

YR903 UHF RFID Evaluation Kit User Manual V1.1
the carrier frequency.
Frequency range the reader supports: 865MHz-868MHz(ETSI), 902MHz -928MHz(FCC).
You can set the reader in RF Spectrum Setup->User Define, as illustrate below:
Users can set RF spectrum via these three parameters: Start Frequency, Frequency Interval, The
number of Frequency points.
2.3 ISO-18000-6C tag inventory
Connect the Reader correctly. Tag operation could be started when RF Setup is completed.
Tag inventory means reader identifying multiple tags’EPC number at the same time. This is the core
function of UHF RFID Reader and one of the standards to judge a reader’s performance.
2.3.1 Real Time Mode & Buffer Mode
The most commonly used mode for tag inventory is Real-time Mode. Data will be uploaded meanwhile
you can get the tags’EPC number instantly. RSSI and Parameter of Frequency are changed and
recorded in real time. Due to its dual CPU architecture, performance of multi-tag identification under
Real-time mode is the best.
The other is Buffer Mode, the data will be cached and uploaded together when you need them. Under
this mode, the data are without repeat data and can keep in small volume, because the data will be
filtered before being uploaded. But it will take some time to filter duplicate data when reader identifies a
large number of tags. Therefore, its identification efficiency will be slightly lower than real-time mode.
Note: Tags can’t be operated when you extract data in the cache.
Users can choose the appropriate method based on actual situation as illustrated below:
Method NO.1: Real-time Mode
1. Click Tag Inventory (Real Time Mode). Select the connected antenna(s) port. Set the number of
Repeat Per Command, which is the times of repeat inventory command. For example, inventory
command will execute anti-collision algorithm one time when you set the value to 1. It will execute anti-
collision algorithm two times when you set the value to 2...
2. Click Inventory, you will find that the EPC number is uploaded immediately and it is real-time
updating. The reader will keep inventory until you click stop as shown below:

YR903 UHF RFID Evaluation Kit User Manual V1.1
Inventoried Quantity Total number of inventory tags since click on Inventory.
Speed Speed of identification Tag, unit: piece / sec
Total Tag Communication Total return EPC data of tags (Including repeated data)
Command Duration Time of each inventory command takes, unit: ms
Total Inventory Duration Total elapsed time since click on Inventory , unit: ms.
ID The serial number of data.
EPC EPC number of tag.
PC Protocol Control word of tag.
Identification Count Times of tag identified.
RSSI The signal strength when tag was identified at the last time.
Carrier Frequency Carrier frequency of tag which is identified at the last time.
Method NO.2: Buffer Mode
1. Click Inventory, the screen will display as below(single tag & multi-tag inventory):

YR903 UHF RFID Evaluation Kit User Manual V1.1
Note: the identified tags won’t be shown in the Tag list.
2. Click Stop first, then click Get Buffer. All the data in cache will be uploaded as illustrated below:

YR903 UHF RFID Evaluation Kit User Manual V1.1
Functions description under Buffer Mode:
Get and Clear: Read the data form cache and then clear the cache. It will be empty when you read the
cache again.
Query tag Quantity: If you just want to know how many tags are there in cache without details, click on
this button.
Clear Buffer: Clear the cache and refresh the screen.
2.4 Accessing ISO-18000-6C Tag
Click Access Tag, and the screen will display as following:
2.4.1 Read tags
You can set the parameter(zones to be read, Start Address and Data Length) as illustrated below:
Note: the unit of Starting Address and Data Length is WORD which is 16 bit double-byte.
Click Read when the parameter setting is completed.
Picture as below shows that one tag has been identified successfully.

2.4.2 Write Tags
The area of Write Tag is the same as Read Tag, but you need to provide access password and
information of data to be written.
When the operation done successfully, the screen will display as follows:
Note: The maximum length of one-time write is 32 Word (64 bytes, 512bits).
2.4.3 Lock Tags
A password is necessary to be provided for locking tags. When the operation is completed successfully,
the screen will display as follows:
