User Manual At this point, the connection between the reader and the computer has been successfully completed. 2.2 Setting RF Parameter After successfully connecting the reader with PC, we need to set some of the most basic RF parameters, such as RF output power and RF spectrum. RF parameter setting is in the Reader Setup->RF Setup page, as shown in the figure 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.
User Manual The power range is 0dBm-33dBm, in increments of 1dB. The default value is 33dBm (2W). After this value is set, it will be automatically saved in the reader and will not be lost after the reader is powered off. The default RF output power is 33dBm.
User Manual limited range. The default RF spectrum norm is FCC (902MHz-928MHz). Method 2: Set the RF spectrum manually. The user customizes the spectrum through three parameters: the starting frequency (unit is KHz, such as 860MHz, you need to enter 860,000), the interval between frequencies (the unit is KHz, the maximum frequency interval is 2500KHz, if you enter 2.
User Manual 2.2.4 Measure RF Port Return Loss Measure the return loss of the antenna port on the interface as shown in the figure below: Before measuring, you need to set the current working antenna port. The default antenna working port is 1. When measuring the return loss of other antenna ports, you need to set the corresponding working antenna.
User Manual parameter (carrier frequency when the tag is read) also change in real time. But it will generate a lot of data. The reader adopts a dual-CPU architecture. Two different chips are responsible for reading tags and transmitting tag data. Reading tags and transmitting tag data are parallel, without interfering with each other, and not occupying each other's time, so users do not need to worry Data transmission will reduce the read performance of multiple tags.
User Manual The meaning of the data display is as follows: Total number of inventory tags since click on Inventory Tag. Inventoried Quantity 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 Tag, unit: ms. ID The serial number of data. EPC EPC number of tag.
User Manual 2.3.2 Users define Session ID & Inventorying Parameter of Inventoried Flag According to the user-defined Session ID and Inventoried Flag parameters to inventory, the reader can inventory according to the user-defined session parameters (four types of session S0, S1, S2, S3) and the inventoried flag (two inventoried flags A, B) parameters .
User Manual 2.3.3 Fast Switching Antenna to Inventory Tags In the operation of standard inventory tags (real time mode, each antenna needs to be commanded to set the corresponding working antenna before inventory), a single antenna inventory requires at least 200 milliseconds. Only after the inventory is completed, the reader can respond to new commands. However, in many practical application environments, it is unacceptable to switch the antenna after 200 milliseconds.
User Manual The working time of each antenna can be set independently. The number of round 1 means that the working time of the antenna is 50ms, and the number of round*50ms is the working time of the antenna. Set the appropriate number of round according to the number of tags in front of the antenna. The default number of round is 1. The sequence of antenna switching and whether to select the antenna inventory can be set as shown in the figure below. 2.
User Manual The following will introduce how to access tags one by one. 2.4.1Read tags The parameters for reading tags are entered in the interface shown in the figure below: Three parameters need to be input to read tags: select the tag storage area to be read, start address and data length. Note: The units of the start address and data length here are both WORD, which is a double byte of 16 bits. After setting the parameters, click the “Read” button.
User Manual Data length input 6 (unit word, read 12 bytes). (5) Click "Read " to read the contents of the corresponding storage area of the tag and display it in the data column of the list box. As many tags are manipulated, how many pieces of data will be displayed in the list. 2.4.2 Write tags The interface of the tag writing operation and the reading operation are in the same area. The difference is that the writing operation also needs to provide information such as access password and writing data.
User Manual (3) Enter the access password, the default is 00 00 00 00. (4) Enter the starting address and data length. The upper four bytes of the EPC storage area are two bytes of CRC and two bytes of PC, so the starting address of the EPC number is 02 (unit word, Start reading after the upper four bytes). Data length input 6 (unit word, write 12 bytes). (5) Enter the data to be written in the "Data to be written (HEX)", such as "112233445566778899AABBCC", 12 bytes.
User Manual Note that the maximum write length at one time is 32 Words (64 bytes, 512bits). 2.4.3 Lock Tags The operation interface of the lock tag is shown in the figure below: The lock tag must provide an access password to proceed. After the operation is successful, the following information will be returned: Similarly, how many tags are operated, how many pieces of data will be displayed in the list.
User Manual 2.4.4 Kill Tags The operation interface of the kill tag is shown in the figure below: The killing tag must provide an kill password, and the kill password cannot be 00 00 00 00. Therefore, to kill a tag, you must first modify the content of the kill password in the password area through the write tag command.
User Manual After the selection is completed, click the "Select" button, and the following figure will be shown after successful operation: We see that the " Selected Tag" checkbox on the left has been ticked, and the selected EPC number appears in the text box on the left. Next, all tag access operations will only be performed on tags with this EPC number. If you want to cancel the matching of EPC, just uncheck the checkbox of the selected tag. As shown below: 2.4.
User Manual The above prompt will appear if there are no tags available for operation in the radio frequency area. For the meaning of other returned information, users can refer to the document: R2000 module serial interface communication protocol V4.0. Every time the UID of the tag is successfully read, the buzzer will beep once. If the buzzer beeps slightly longer, it means that the reader has activated the anti-collision function and recognized multiple tags at the same time. 2.5 Other Settings 2.5.
User Manual The operation interface is shown in the below: Users can read and write GPIO through serial commands in their own applications. 2.5.3 Setting Buzzer Status The buzzer provides users with sound information about the status of the reader. The user can turn off the buzzer, or set it to sound once every time the tag is inventoried. It can also be set to beep every time a tag is read, but this will reduce the efficiency of multi-tag recognition. This function is more used to test tags or readers.
User Manual After the setting is successful, the new baud rate will be saved in the FLASH inside the reader, and will not be lost after the reader power off, restart the reader to make the setting effective. At this time, it must communicate with the reader at the new baud rate. caution: If the interface used by the user is a TCP/IP interface, then the TCP/IP module must be changed to the corresponding serial port rate.
User Manual The purple-blue information is the data sent by the PC to the reader, and the red information is the data returned by the reader to the PC. The function of manually sending data can be used by users to debug serial commands, and it has the function of automatically calculating the checksum. In addition, the attached document also includes the complete source code of this demo program (based on the C# language development of the .
