NFC_V3 User Guide 1. Abstract RFID antenna board through the GD32F130 master controller, control NXP663 13.56M NFC antenna controller for NFC electronic tag reading and writing. The antenna board senses that the drawer is closed (the magnet enters the sensing range of hall sensor), and the main controller reads NFC antenna controller NXP663 before and after opening in turn, and transfers the read data to the LCD display through the 485 bus, and the display controller displays it and transfers it to the server through the WIFI wireless network. When the RFID antenna board receives the positioning instruction through the 485 bus, the RFID antenna board parses the content according to the instruction, and the LED before or after the opening is used for positioning guidance. 1.1. Keywords 1. 485 bus communication: directly installed in the metal frame, through the 485 communication line bus, 485 control board and display screen for communication control. 2. Reading distance: in the case of shielding metal interference, the reading distance is less than or equal to 10cm;
3. Waterproof technology: the antenna box is equipped with waterproof rubber ring, and the RFID antenna board is sealed in the box, which can protect the operating environment of the antenna board and prevent the condensed water from affecting the stability of the antenna;
4. Hall induction: RFID antenna front end is connected with hall sensor, when there is a magnet drawer closed, hall sensor trigger, can be induced to close the drawer. When the drawer is pulled out and the hall induction disappeared, the antenna board judges the drawer is open. 1.2.

Host Device Model Name:
Manufacturer:
H-P01 Qingdao Haier Biomedical Co Ltd Federal Communications Commission (FCC) Interference Statement The limited modular transmitter is only FCC authorized for the specific rule part (FCC Part15.225) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate this equipment. For additional hosts other than the specific host originally granted with a limited module, a Class II permissive change is required on the module grant to register the additional host as a specific host also approved with the module. OEM/Host integrator is responsible for complying with the instructions and requirements for each transmitter they choose to integrate into a host product. RF exposure warning This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This product may not be collocated or operated in conjunction with any other antenna or transmitter. This equipment must be installed and operated in accordance with provided instructions and the antenna(s) used for this transmitter must be installed to provide a separation distance from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter. Additional text needed for the host product manufacturer to provide to end users in their end-product manuals. OEM Integration Instructions This device is intended only for OEM integrators under the following conditions The module can be used to installation in other host. And the transmitter module may not be co-located with any other transmit or antenna. The module shall be only used with the integral antenna(s) that has been originally tested and certified with this module. This module must not be incorporated into any other device or system without retesting for compliance as a composite system per Part 2.947(f). However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirement with this module installed (for example, digital device emission, PC peripheral requirements, etc.) IMPORTANT NOTE In the event that these conditions cannot be met (for example certain laptop configuration or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these and circumstance, the OEM integrator will be responsible for re-evaluating. The end product (including the transmitter) and obtaining a separate FCC authorization. The final end product must be labeled in a visible area with the following:
Contains Transmitter Module FCC ID: 2ASR8NFCV3 or Contains FCC ID: 2ASR8NFCV3.
