modulated carrier signals and transmit the signals by selected antenna. →The unit receive the back scatter signal from the RFID tag.After demodulating , amplifying ,comparing the signals ,the unit transmit the signals up to baseband unit. →The unit adjust output power and frequency of the antenna interface under the control of the baseband unit. 3.1.2 Baseband unit: →The unit receive data & command from PC via RS-232 interface,or send data & results to PC ; →The unit transmit control signals of tags to RF unit; →The unit accept tag signals from RF unit, modulate signals and checkout; →The unit can modify or query configure information of interrogator under the control of PC command ; 3.1.3 Power unit: →converts incoming alternating current (AC) to direct current (DC),out DC power supply for the integrated equipment. 3.1.4 Data interface unit: →Standard connector to connect the COM port ,network and power interface with the rear panel of the integrated equipment ; 3.1.5 Case unit: →The interrorgator case is made of molded-in ABS/PC. And the anti-static coating was sprayed over the inner surface of the case; 3.2 Fundamental working principle The complete RFID system is consist of XCRF-804 interrogator, antenna, tags, and pc. The baseband send the command to RF unit under the control of PC.RF unit send signals to tags according to the tag type. When the tag is activated, it sends out its number as well as other information . The tags' response signals was amplified and shaped by the received-data
circuit. Then the signals was send to baseband unit. The baseband will decode the received signal and then sends to PC via the communication interface of the baseband unit. The transmitting part of the RF unit will take the function of carrier generation, carrier modulation, amplification and emission. The receiving part of the RF unit will take the function of demodulation, amplify , compare etc. The FPGA part of baseband will take the code/decode function to tag data. MCU will take the function of communication with PC. 4 Usage and operation 4.1 Interrogator connection There are 4 antenna port on the XCRF-804 interrorgator .The output port of antenna interface is SMA plug. You can find antenna Cable with reversed SMA-Plug to N-Plug Connector in the product accessories. Joint the antenna SMA plug to the SMA interface of interrorgator and tight the bolt. The fit another port of the antenna cable with proper antenna. 4.2 Interrogator usage and operation Connect the device as stated above, and the interrorgator will work under the control of PC command. Our company provide API function and interrogator demo software .User can use the software to test the interrogator. Please read user manual of the interrogator demo software to get the information about test procedure and test method. 5 Usual failure analysis and exclusion ·When the interrorgator is power on the signal lamp is not lighted: →power fault: check if the input alternating current power is normal. The alternating current voltage should between 85V～265V; →If the other signal lamp is light, there is MCU or FPGA fault in the device. Once you meet this problem, you can only contact with Invengon company to repair the
device; ·Can't read tag data: →Please check if the serial port or the network cable is connect to the interrogator correctly. If the cable is not joint firmly, interrogator can not get command from PC. →If the power amplifier signal lamp is light ,user need to check if the antenna SMA connector is screw down, or if the tag is fault. But if the power amplifier is not light, maybe the FPGA or MCU is fault. User should contact Invengo company to repair the device; 6 Other notice 6.1 Production warranty The warranty: period of our products is 2 years from delivery . If a defective is found due to material processibility qualified problems of the product , we will perform warranty commitment. Invengo company will decide whether repaire or replace the fault product with certain qualified problem. If a problem occurred is because the user's operation environment is not accord with the product Specifications, or a problem occurred due to installation reasons, we will not perform warranty commitment. we may charge the maintenance costs. 6.2 Safety note When interrorgator is working (emitting microwave),person who install or operate the device should be 30cm away from antenna to meet the FCC safety standards requirement about maximal tolerant radiation human body can take. The item should be carry out when user intall or operate the interrorgator. Not undertake item: Any RF device, include this interrogator , maybe disturb the medical device without correct protection. If you face this problem , you should listen to the counsel of medical device manufactory . This interrorgator may disturb other device when
working . Invengo Information Technology Co. Ltd. Add:3/F,No.T2-B High-Tech Industrial Park South,Shenzhen. Zip Code:518057 Tel:0755-26711633 26711690 Fax:0755-26711693 http://www.yuanwanggu.com.cn http://www.ywgit.cn http://www.invengo.cn http://www.invengo.cc E-mail:sales@yuanwanggu.com.cn
