UHF RFID Reader Application Specification 3.1 UHF RFID application system introduction I84/I84E/I85/I86 series of readers should accord with the following implementation specification in the application system. 1The installation conditions of UHF Reader 2The installation conditions of Tag 3The electromagnetic response in UHF band 4EMC Electro Magnetic Compatibility. 3.2 The installation conditions of UHF reader 3.2.1 Installation examples of UHF reader There are some installation examples of the I84/I84E/I85/I86 series integrated reader. Antenna plane of reader should be in the right orientation with the tag to be identified, and there is no other media between them. 3.2.2 Tags direction in the application system It will affect the reading range and performance if the tag is at a different angle from the reader antenna. In order to achieve an optimal reading effect the tag should be aligned with the reader antenna. 6 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd Tag Antenna orientation: Right at the reader;

Reading distance:Farthest;

Reading performance:Optimum. Tag Antenna orientation: Vertical with the reader;

Reading distance:Shortest;

Reading performance:Worst. 3.2.3 Crosstalk between readers in the application system When multiple RFID readers are working in the application system at the same time, the unreasonable installation method will result in the risk of the tag being read by other readers.For example, the installation direction between the reader antennas is not standardized, and the distance between adjacent readers is too close. To avoid crosstalk, adjacent readers operating in the same frequency band should maintain a minimum safe distance.This distance mainly depends on the maximum effective radiated power (ERP) of the reader and the directional relationship between the reader antennas. The following shows three common multiple reader installations:

Fig 3.2.1 Back to back Fig 3.2.2 Side by side Fig 3.2.3 Face to face 7 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd Installation method Back to Back Side by Side Face to Face I84/I85 minimum safety clearance D 1.5m 3m 8.0m I86 minimum safety clearance D 2.0m 3.5m 10.0m Note: This table is only used as a reference for testing specific tags in an ideal environment. More specific requirements depend on the field application environment. 3.2.4 Reading distance in the application system The effective distance which a reader reads a tag is related to many factors. Including but not limited to the following conditions:

Reader power. In theory, the greater the power, the farther the effective distance of reading the tag. Tag. Tags of different types, sizes, and production qualities have different reading distance. Reader or in an tag installation environment. When the reader electromagnetic wave reflective environment or the tag is mounted on a different material surface, the read distance of the reader varies. is Read and write operations. The write operation of the reader requires more power than the read operation, so the write operation distance is much closer than the read operation distance. The following figure shows the read/write distance comparison of the tags in the reader antenna field. Fig 3.2.4 Distance comparison implementation specification,so as Therefore, the installation environment of the reader is as close as possible to the reliability and effectiveness of the reader reading the tag. On the other hand, adjacent readers should be kept above the minimum safe distance and properly adjust the reader transmit power to reduce mutual interference between readers. to improve the 8 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd 3.3 Tag installation environment specification Tags with different attributes have different installation environments.For example, when the reader parameters are the same, the anti-metal tag is mounted on the metal surface much farther than the distance mounted on a non-metallic surface.The tags are divided into two categories: anti-metal tags and non-metal tags. Non-anti-metal tags are recommended to be installed in non-metallic environments. If to the following there is no legal environment implementation rules:

Mounting on metal surface Non-anti-metal tags require a buffer to be reserved, and anti-metal tags can be directly mounted to metal surfaces;

BufferRefers to the distance from the tag to the metal surface 1 Non-anti-metal tags are mounted on metal surfaces, buffer 20mm, and tag to avoid metal, please refer performance can be retained above 80%

tags are not recommended for 2When the anti-metal tags is directly mounted on the metal surface, it can still retain more than 90% of the original performance;

Embedded metal mountinganti-metal tags can be directly embedded in metal applications,non-anti-metal embedded metal applications. Free zoneRefers to the blank area around the tag when the tag is embedded in the metal. 1When the anti-metal tags are embedded in the metal installation without leaving a free area, the tag performance can still be maintained above 90%;

2If the non-anti-metal tags are embedded in the metal mounting surface, the free area a2X, b2Y, c20mm must be reserved. At this time, the tag can retain more than 80% of the original performance;

Figure 3.3.1 Tag Installation Environment Specification 3.4 Electromagnetic wave response in the UHF band When electromagnetic waves propagate in the UHF band, they are constrained by some environments (such as metals, walls, liquids, other signal transmitters, etc.), resulting in reflection and mutual interference.This phenomenon may be 9 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd reflection;

the reader through metal it may also be that is extremely difficult to reduce the influence of manifested by the fact that the electromagnetic wave signal expands the reading range of the electromagnetic wave signal is interfered by other signals in the same frequency band to reduce the reading range of the reader. Due to these electromagnetic characteristics,it to determine the propagation path of the signal and its field strength when the reader is in a multiple reflection environment. reflection and interference on the In order identification tag, it is recommended to appropriately reduce the transmit power of the reader so that it can properly identify the tag. In addition, when the ground is poor and the reader is installed on the metal, it may affect the performance of the reader. Therefore, pay attention to the following points when installing the reader in the metal environment:

Embedded metal mountingReserved buffer (buffer can add non-anti-metal media) BufferRefers to the distance from the reader to the metal surface 1. The buffer is 0cm, that is, when directly mounted on the metal surface, the read/write distance of the reader will be reduced by at least 10%; the specific data is related to the metal material, size, thickness, etc.;

2. When the buffer is 20mm, the performance of the reader is close to that of the non-metal plane; It is recommended to design the buffer to be larger than 20mm during installation. Fig 3.4.1 Nut type reader metal environment installation If the reader housing is made of metal, it is recommended to use a plastic bracket when the ground is not good. Embedded metal mountingReserve a free area that is large enough. Free zoneRefers to the metal blank area around the reader when the reader is embedded in the metal installation. 1. When A = 0cm, that is, when the reader is installed without a reserved free area, the reader will be seriously reduced.This the read/write distance of installation method is not recommended;

2. When A = 10cm, the actual reading and writing distance will be reduced by 10%; the specific data is subject to the actual application test;

is In order the requirements of necessary to reserve enough free actual application (the recommended value of A is not less than half of the length and width of the reader);

reading and writing distance, to meet in the zone it 10 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd Installing the reader in the metal frame - avoiding the conductor loop Fig 3.4.2 Embedded metal environment Fig 3.4.3 Round metal frame installation If the reader is in a closed metal frame, the metal frame will reflect and disturb the electromagnetic wave signal. At this time, the antenna field and the transmitting field over -lap each other, and the reader cannot receive the valid signal normally, resulting in abnormal reading. The closer the metal frame is to the reader, the greater the interference, and the installation should be avoided in practical applications. 3.5 Electromagnetic compatibility 3.5.1 Electromagnetic compatibility guidelines Electromagnetic compatibility refers to the ability of an electronic device to environment.Electromagnetic function electromagnetic an to the is detrimental interference is an electromagnetic phenomenon that properly in 11 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd and and electronic arrangement of performance of electronic equipment.Electromagnetic interference not only affects the normal operation of electronic equipment, but even causes damage to certain components in electronic equipment. With the increase in automation, electrical equipment becomes more the is risk complicated, the increased.Electromagnetic parts:

interference mainly interference source, coupling path and interference receiver. When applying the implementation plan in the field, it is necessary to identify the most frequent sources of interference and the possible coupling paths that exist, so as to take corresponding measures to reduce the risk of electromagnetic interference and ensure the normal operation of the equipment. In order to ensure electromagnetic compatibility enough, the following rules must be observed:

between of devices three interaction consists of 1The device is shielded by the outer casing. The reader-related equipment is installed in the cabinet and grounded through the rack to shield the external magnetic field. 2The equipment is well grounded.Good grounding can ensure the clean the power supply of the equipment, and on the other hand, excessive impact voltage from being damaged when the equipment fails, and damage the reader. it can prevent 3 Cable shielding. For sites with complex electromagnetic environments, shielded communication cables must be used to avoid interference signals being coupled to the cables. 4 Signal and line filtering. Install the filter in the power inlet or cabinet inlet direction to avoid interference from the power source into the device. 3.5.2 Power supply and wiring requirements In an industrial environment, a major source of interference in equipment circuits is caused by unreasonable ground lines. Therefore, proper grounding is an important method to suppress noise and prevent interference, and is the key to ensure the normal operation and read/write success rate of the reader. Under normal circumstances, the reader device power supply voltage is 24V, which is a weak current. When wiring, connect the power supply line of the reader and the 485 power supply line from the weak current slot, and the cable slot must be connected to the standard earth0Level. Note: If the grounding of the slot and shield is not guaranteed to be the standard "0" potential, you need to provide independent power for the RFID or add a filter to the power supply. 12 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd 3.5.3 Common electromagnetic interference causes and solutions The following provides a reference to some common electromagnetic interference solutions The switching power supply interferes from the current conduction to the device. It can be solved by replacing the independent power supply or adding a filter at the power supply. Cable couple Electromagnetic interference in the space. Insufficient cable shielding or the reader is not well grounded, which can be solved by improving the shielding performance of the cable and making the reader well grounded. Antenna interference between readers. It can be solved by increasing the safety spacing of adjacent readers and reducing the transmit power of the reader. Control cabinet or chassis interference. The electrical planning of the control cabinet or the casing is unreasonable, the grounding is missing or bad, and the0potential imbalance causes interference,which can be solved by rationally designing the control cabinet or the casing. 4.

It is convenient for enterprise distributed deployment and batch networking to satisfy different read distance requirements. The following briefly describes the electromagnetic field distribution of the antenna and the effect of the field on the tag. As shown in the figure below, the radiation field of the antenna is divided into three parts: the main lobe, the side lobe and the back lobe. Fig 5.1 Antenna radiation field distribution Fig 5.2 3D antenna radiation field distribution The radiant energy of the antenna is mainly concentrated in the main lobe area. In practical applications, the tag should be read as far as possible in the main lobe field of the antenna to achieve a better recognition effect. The upper side lobes have a higher angle and a longer influence distance, which easily causes cross-region interference. That is, if adjacent tags are too close, the antenna will read other tags. Between the main lobe and the lower side lobes, there is a lower zero trap, which will cause a signal dead zone at this position. The "lower zero depth" vacancy can be filled by means of beam shaping. It is also worth noting that when the reader is installed down, the amplitudes of the vertical and horizontal components of the antenna are constant, so the antenna pattern will be deformed. At this time, the tag antenna and the reader antenna are not flush, the read/write range is affected to some extent. 25 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd Fig 5.3 Antenna down-radiation field distribution map 6. Networking Application Sygole I84/I84E/I85/I86 series products support multiple communication modes. During networking application, the user may select a suitable communication mode according to the practical application conditions. Generally speaking, the hardware topology graph for application is as shown in the following figure:

6.1 Field bus communication mode In some cases, the field bus communication mode should be adopted to meet such application requirements for large amount of RFID reader heads and high data timeliness.Sygole I84/I84E/I85/I86 series products can support the field bus through gateway controller, and support such protocols as ProfiNet, EtherCAT, Ethernet/IP, DeviceNet, CCLINK and MODBUS TCP. Specifically, readers are connected to the gateways which are mutually connected in series. In this way, all readers can be connected to the same network. Specifically, the networking mode is as follows:

Common failure problems and solutions for UHF readers SYGOLE provides customers with industrial UHF readers that meet the application requirements of different scenarios. This chapter mainly answers some common failure problems and solutions about UHF reader modules. 8.1 Antenna matching In short, when the load impedance connected to the feeder terminal is equal to the characteristic impedance of the feeder, it is said that the feeder terminal is matched. During matching, only the incident wave transmitted to the terminal load exists on the feeder, and there is no reflected wave generated by the terminal load. Therefore, when the antenna is used as a terminal load, the matching can ensure that the antenna obtains all signal power. In actual work, the input impedance of the antenna will also be affected by surrounding objects. In order to make a good match between the feeder and the antenna, it is necessary to measurement antenna and properly adjust the local structure of the antenna or install a matching device when setting up the antenna. It should be noted that the antenna is more sensitive to the outside world. After changing the antenna environment, the antenna must be matched again. When the input impedance of the antenna is 50 ohms or close to 50 ohms, the matching is best 8.2 Use DEMO software to connect with RLM series product hardware After ensuring that the power supply of the module product is normal, use the serial port or network port to connect to the PC, check the COM port corresponding to the module product in the device management of the PC, start the DEMO software, and select the COM port corresponding to the module product in the [Basic Operation]

column , Click the [Connect] button. For network port models, write the default IP address 192.168.1.20 and port 3001 in the DEMO software, and click the [Connect] button. 8.3 The DEMO software failed to connect with the reader 1) No software driver is installed. The so-called software driver is essentially a common serial port driver, which can be obtained from the supplier. 32 UHF Integrated RFID Reader Manual Guangdong Sygole Intelligent Technology Co.,Ltd 2). Please ensure that the power supply of the reader device is normal. If the reader device does not have a rated power supply, the DEMO cannot be connected to the device. 3) The COM port selection is incorrect. If you connect the device to the PC, please check the COM port number used by the reader device in the PC device manager, and make sure it is consistent with the COM number you selected in DEMO. If the reader device is not connected to the PC, please use other methods to determine whether the selected COM port is correct. 4). The network port connection must select the IP address connection, and the serial port must select the COM connection. 5) Whether the wiring is correct: Please ensure that the wiring connected to the reader device is correct. The standard cable wiring method is: brown +, blue -, white A, black B. 8.4 Processing method of unstable read distance 1). Use an independent power supply as much as possible for the power supply to ensure that the remaining 30% of the power margin is at the highest power efficiency and the smallest ripple. Use at least 0.38mm^2 for the power cord, and add a filter if necessary. 2). The power supply voltage input range is determined to be within 24V+-20%, and it can be used if it exceeds the range, but the stability is relatively poor;

3). The length of the feeder is too long and seriously bent, resulting in too much loss. 4). The antenna connector is loose. 5). The reader should avoid irregular large areas of metal around it, and keep it away from the frequency converter and inverter. 6). Avoid turning on two readers at the same time. 7). The radiating surface of the tag antenna is facing the front of the reader, and the reading distance is the farthest. 8). The actual use distance cannot exceed 50% of the estimated distance. 8.5 The long-term working reliability of the reader decreases The product has a watchdog function inside, which effectively prevents crashes. The products use high-reliability parts, including industrial grade and automotive grade. Die-cast metal shell can effectively passively dissipate heat. When the ambient temperature is >55, active cooling equipment must be used. Or reduce the card reading power and reduce the number of card readings. 33 FCC NOTICE:
