WKX-MR382.4G Tag

2.45GHz Active tag introduction 1. The Appearance 2. Introduction This tag is a 2.4GHz active tags, matched with MR3001A reader, it can be written to data and read out data, it has 240 Bytes memory for users to store data. It uses two button lithium batteries to supply the source, and it has a long lifetime and change battery is easily. At normal status, the tag is in sleep mode to save battery, when MR3001A is working, it will wake up this tag, then the tag will send its ID to reader to finish the communication. 3. Applications and Features ●MR3820A active tag can be used in location system or personnel registry, and even conference attendance, etc. ●It should be matched with MR3001A reader to use in the real application ●Independent sending and receiving frequency, has a strong anti-interference ability ●The maximum indentify range can reach more than 80m(depend on the antenna of reader and the tag’s sending power), ultra-wide frequency band design ●Multi-tag indentify at the same time (more than 50/s) while it can not be affected and limited by the amount of tag within the antenna’s indentify range. ●Large memory for users to store data 4. Specifications Model name MR3820A Card shape Card ID type 4 byte ID Working frequency 2.44GHz Modulation GFSK Sending power 0dBm -6dBm -12dBm -18dBm(0dBm is the maximum and -18dBm is the minimum, the power can adjust the identify range) default is 0dBm Sending time interval 0.25s, 0.5s, 1s, 2s, 4s (default is 1s) EEPROM size 240 bytes storage capacity Inductive mode Auto-inductive Identify range 3-80M LED indication When using the reader call a tag, the Led on tag will be twinkling Material PET, heat-resistance, water-proof Dimension 87mm*55*mm5.5mm Weight 20g Battery 2 pcs 3.3V built-in button lithium Use life 3 years 5 Tag memory Address Storage content Addr0~3 store the tag’s ID Addr4~7 store the working parameters of tag Addr4 store the interval time of tag automatically detect (automatically sending signal), 0x10，0x11， 0x12，0x13，0x14 are separately related to 0.25s，0.5s，1s，2s，4s(sending time interval);the default is 1s Addr5 the sending power of tag, 0x10，0x11，0x12，0x13 are separately related to -18dBm,-12dBm,-6dBm,0dBm; the default is 0dBm. Addr6 setting the tag’s sending mode (passive or active, 0xAA is active, others values are for locating tag) Addr7 reserved Addr8~15 reserved Addr16~255 user data 6. Usage of MR3820A tags In real application, the system need MR3001A reader and MR3820A tags, and also a switch and PC is needed to exchange the data. See following picture, reader wake up the sleepy tags, and then tag will automatically send its ID and status information to reader. One tag will mark one person or goods. It can tell us the position of person or goods by the reading procedure. If the tag is stayed within the reader’s reading range, it will be identified by the reader. 7. Use Demo software 2.45GDemo.exe is supplied to show the communication between reader and tags The reader has com port and Ethernet port to connect with PC. The default sending time interval is 1s with the sending power is 0dBm. Here we connect it with com port. Following show the result of identifying. Start or stop tag identify Tag ID display Tag records Write or read tag data FEDERAL COMMUNICATIONS COMMISSION INTERFERENCE STATEMENT This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. CAUTION: To assure continued FCC compliance: Any changes or modifications not expressly approved by the grantee of this device could void the user's authority to operate the equipment.

1 Description: 1. MCU PIC16F690 scan KEY, when KEY is active, MCU send the data of tag to 2.4GHz RF transceiver nRF24L01 , and MCU flash the red LED. nRF24L01 send 2.4Ghz FSK radio frequency with data of tag. The RF signal send to air from antenna. 2. MCU PIC16F690 control the 2.4GHz transceiver to receive state. When the nRF24l01 receive the RF signal from reader, decode the data from FSK RF signal ,send the data to MCU via SPI. 3. MCU receive the data ,and check the value is ok, flash red LED. And repeat the step 1.
