3 Design fundamentals 3.1 Device compose As figure 4－1 and 4－2,XCRF-502C reader has 5 parts:RF unit, baseband unit,power unit、data interface unit、case unit. figure 4－1 reader RF unit fundamental block diagram figure 4－2 reader baseband unit fundamental block diagram 3.1.1 RF unit: →The RF unit receive baseband signal and modulate carrier,then amplify the 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 reader 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 reader case is made of molded-in Aluminum. 3.2 Fundamental working principle The complete RFID system is consist of XCRF-502C reader, 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 Reader connection There are 2 antenna port on the XCRF-502C reader .The output port of antenna interface is N plug. 4.2 Reader usage and operation Connect the device as stated above, and the reader will work under the control of PC command. Our company provide API function and reader demo software .User can use the software to test the reader. Please read user manual of the reader demo software to get the information about test procedure and test method. 5 Usual failure analysis and exclusion ·When the reader 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 100V～240V; →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 reader correctly. If the cable is not joint firmly, reader can not get command from PC. →If the power amplifier signal lamp is light ,user need to check if the antenna N 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 reader 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 install or operate the reader. Not undertake item: Any RF device, include this reader , maybe disturb the medical device without correct protection. If you face this problem , you should listen to the counsel of medical device manufactory . This reader may disturb other device when working . Invengo Information Technology Co. Ltd.
