The following will be one by one on how to carry out the label access operation
。
1.3.1 Read the label operation
The parameters of the read tag are entered in the interface shown below
：
The read tag needs to enter three parameters: the label area to be read, the start address and the data
length. Note that here the starting address and
The data length units are WORD, which is 16 bit double bytes. When the parameter is set, click the Read
tab button.
It should be noted that the input parameters to meet the specifications of the label, otherwise there will
be an error
。
When the operation completes successfully, the feedback shown below appears

How many tags are displayed and how many pieces of data are displayed in the tag list
。
1.3.2 Write the label operation
Write the interface of the label operation and read operations in the same area, the difference is that
the write operation also need to provide access to passwords and write data to this information
。
The password area is part of the electronic tag that stores the password (password). Including
inactivation passwords and access passwords. The inactivation password and the access password are 4
bytes. Where: the address of the inactivation password is 00H-03H (in bytes); the address of the access
password is 04H-07H
。
After the operation is successful, the feedback shown below will appear

How many tags have been successfully operated, and how many pieces of data will be displayed in the
list. Unlike the read tags, there is no content in the data column on the map above. The user can read the
same area of the tag again to verify that the data is written correctly
。
Note that the maximum write length is 32 Word
（
64 bytes
，
512bits
）。
1.3.3 Lock the label operation
The operation interface of the lock label is shown in the following figure
：
The lock tag must be provided with an access password to proceed.
Note: The original password lock is invalid, it is recommended that users first modify the access password
and then lock the label
。
After the operation is successful, the following information will be returned

Similarly, how many tags are displayed in the list, and how many pieces of data are displayed in the list
。
1.3.4 Kill the label operation
The operation interface of the deactivation tag is shown in the following figure
：
The deactivation tag must provide an inactivation password and the inactivation password can not be 00
00 00 00. Therefore, to destroy a label, first change the contents of the password inactivation password
by writing a tag command
。
After killing tag is successful, the following information is returned
：
How many tags are displayed in the list, as with all access to the tag, how many records are displayed in
the list

1.3.5 Select the label operation
In many cases, we hope that no matter how many labels in the RF area, only for a known EPC number of
labels to access operations, this time, you need to use the selected operation of the label function (EPC
matching function)
。
In the accompanying demo software, operate as follows
：
◆
First save the label, get all the EPC number
。
◆
And then go to the interface to access the tag, select the EPC number to match. As shown below
：
When the selection is complete, click the selected tab, as shown below
：

Next, all access label operations will only be performed for labels with this EPC number
。
If you want to cancel the EPC match, just click Cancel in the drop-down menu and click the Select button.
As shown below
：
1.3.6 Access the label may return an error message
In the process of access to the label operation, if the operation is not correct, there will be an error message,
then we listed some common operational problems.
◆
Successful inventory but failed to access
：
ORCA-50 UHF Demo Manual V1.0
13 Eximia Srl
–
www.eximia.it
- www.rfidstore.it
The process of accessing a tag is actually divided into two steps, first by disk, and then accessed. The
above prompt indicates that the label is successful, but the access operation is not possible
。
In general, there are two reasons for this problem, one is the parameter settings are wrong, such as
reading does not exist in the storage area, another reason is that the RF energy is not enough, access to the
operating distance of the label is about the disk operating distance 60% to 70%, so if this is the case, please
move the label closer to the antenna
。
◆
Access password is wrong
：
The cause of this problem, as described in the prompt, is that the access password is set incorrectly
。
◆
There is no operational label error
：
There are no labels available for operation in the RF area
。
The meaning of the other return information, the user can refer to the document

ISO-18000-6B label operation and ISO-18000-6C label operation similar to the following figure
：
Every time you read the UID of the label once, the buzzer will be short. If the buzzer sounds slightly
longer, then the reader starts the anti-collision function and simultaneously identifies multiple tags
。
1.4.2 Access ISO-18000-6B tags
Access to the leaflet ISO-18000-6B label can only be accessed. Click the Access tab button to select the
label to be operated in the UID list, as shown in the following figure
：
The next operation is relatively simple, the user can operate on their own. Note the following points
：

The incoming data will not be changed, and the reader will return the number of bytes successfully
written
。
◆
Only one byte of card data can be locked at a time
。
◆
Only one byte of data can be queried at a time
。
◆
Locked byte operations are permanent and irreversible

1.5 RF parameter settings
After successfully connecting the reader, we need to set some of the most basic RF parameters, the output
power and spectral range
。
The setting of the RF parameters is set in the reader settings -> RF parameters page, as shown in the
following figure
：
1.5.1 Set the RF output power
RF output power refers to the antenna signal output RF signal strength. The unit is dBm
。
ORCA-50 UHF Demo Manual V1.0
16 Eximia Srl
–
www.eximia.it
- www.rfidstore.it
The output power range is 0dBm - 33dBm. The default value is 30dBm (1 W). After this value is set, it will
be automatically saved inside the machine, the machine is not lost after power failure
。
1.5.2Set the radio frequency spectrum specification
In different areas, there are different requirements for radio frequency spectrum.
There are two ways to set the reader's spectrum.
Method 1: Use the default frequency of the reader.
The default frequency of the reader can refer to the frequency parameter correspondence table in the
communication protocol.
The reader supports a frequency range of 865MHz - 868MHz, 902MHz - 928MHz.
Use the drop-down boxes and buttons shown below to set the desired operating frequency range
。
When setting the spectrum range, please note the following points
：
◆
The starting frequency and end frequency can not exceed the range of RF specifications.
ORCA-50 UHF Demo Manual V1.0
17 Eximia Srl
–
www.eximia.it
- www.rfidstore.it
◆
The starting frequency must be less than or equal to the end frequency.
◆
Set the starting frequency and end frequency to the same frequency. The reader will work at constant
frequency.
This parameter is set, the reader's RF carrier will be in the restricted frequency range of random
frequency hopping.
The default RF spectrum specification is FCC (902MHz - 928MHz)
。
Method 2: user-defined reader spectrum.
The user uses three parameters to define the spectrum: the starting frequency, the frequency interval,
the number of frequency points
。
Note: In order to improve the anti-jamming performance, American Standard and European standard
frequency band equipment selected hardware is different, it can not meet the compatible American
standard, the European standard two bands
。
1.5.3 Set the antenna connection to receive
Antenna connection to receive the function is: read and write tags before checking whether the port is
connected to the antenna, if not connected, then notify the user antenna is not connected.
Before using the user to open this function, through the interface shown below to view, set the
interface of this function as shown below
：
The sensitivity of the antenna detection is set by the user. Antenna detection sensitivity is the antenna
port return loss value (Return Loss), the unit is dB. The greater the value, the better the impedance matching
between the antenna and the port. In general, a normal antenna can set this threshold to 3 - 6 dB. Ceramic
antenna or handset antenna can reduce the sensitivity lower. If the return loss threshold is set to 0, it means
that this function is disabled and the status of the antenna connection will not be detected before reading
and writing the tag.
If the antenna is not connected, read and write tags when the operation will return to the antenna is
not connected to the error message
。
1.5.4 Measure the return loss of the current antenna port
The return loss of the antenna port is detected at the interface shown below

1.6Other settings of the reader
1.6.1Monitor the operating temperature
In the high-intensity continuous use of the reader, it will produce heat, the user can through the built-in
temperature sensor to monitor the reader internal operating temperature, to avoid overheating (operating
temperature of more than 65 degrees Celsius). If the temperature is too hot, you can stop reading and
writing labels for a period of time
。
The operating interface for monitoring the temperature is as follows
：
1.6.2 Set the buzzer status
The buzzer provides the user with the sound information of the reader's use status.
The user can turn the buzzer off or set it to sound every time the label is saved.
It can also be set to sound every time a label is read, but this will result in a reduction in the efficiency of
multi-tag recognition. This feature is more
Is applied in the test label or reader occasion
。
The operation interface is as follows
：
It should be noted that the success of the self-test after the buzzer sound is not controlled by this
ORCA-50 UHF Demo Manual V1.0

setting.
After setting, the state of the buzzer will keep the FLASH inside and outside the reader, after the power
is not lost
。
2.
Develop your own RFID application
Users can use the demo program to operate most of the functions of the reader, but in the actual
application environment, it is necessary to develop the user's own program
。
The accompanying documentation: UHF_RFID serial interface communication protocol _V2.38.pdf
provides a complete interface for operating the reader.
This interface is based on serial communication, so regardless of the user's physical interface is RS - 232
or TCP / IP, the reader is to follow the definition of this interface
。
Demonstration program provides an important function is the serial port transmission records, the user
with the communication protocol documentation and demo program operation process of the actual serial
data to compare, you can quickly grasp the contents of the communication protocol
。
Select the lower right corner of the open serial port monitoring check box, all the uplink and downlink
serial data will be recorded, as shown below (open the serial port monitoring, the software response speed
will slow down, so usually should close the serial port monitoring.
