RFID Smart Device (UHF RFID Reader Module include) U-ways Ver. 1.0 User Manual Sept. 2007
KIS900EMM Reader functional description. Reader includes 1 PCB – Transceiver and Controller UHF. Transceiver uses homodyne receiver architecture that cover the main bands of operation considered for Korean, US, EU and other global applications. The homodyne topology is classic approach for backscatter radar where received signals are close in frequency to the transmitted carrier. A homodyne receiver performs a direct conversion of the received RF signals to a zero intermediate frequency (IF) baseband. This architecture uses demodulator in quadrature along with low pass filtering. A 26 MHz crystal oscillator is used as the clock signal for the PLD synchronization IC. 13 MHz temperature compensated crystal oscillator serves of the reference in the phase-locked loop (PLL) employed to generate the RF carrier signals. This PLL Frequency Synthesizer operates under control of the Controller UHF. The PCB Type coaxial connectors make the RF interface. There are two separate antenna ports – each port transmit and receive signal. which are connecting throw Rx SW and Tx SW to input Rx band pass filter and to PA output band pass filter accordingly. The tag uses Pulse Interval Encoded Data Packets. Generating pulses at variable time intervals performs the data coding. The duration of the interval between two successive pulses carries the data coding information. This is known as Pulse Interval Encoding, (PIE) or GLITCH encoding. Glitch or PIE encoded data signal have dc component.
Transceiver uses Pulse Detector with a DC component threshold tracking. That Pulse Detector make a dynamically adjusting of the threshold level in a detector to detect different pulse polarity, having dc component, as positive as negative pulse packets thereby eliminating false triggering caused by input noise and increasing the restoration quality of the pulse duration and intervals between neighbor pulses. When Reader is activated and interrogates Tags, there is used pulse mode energizing of Tags with S/W controlled the time of emitting and frequency occupation with almost equal time occupation and emitting pause. Reader’s Communication with UCODE EPC Tag satisfies OID Radio Frequency Identity Protocol Generation 2 Identity Tag, Class 1. Manchester encoded Data to Tags is applied to Modulator and modulates carrier using ASK modulation The reader’s Controller UHF uses an inexpensive microprocessor to control reader operation, power management and data processing. The embedded controller executes firmware routines to energizing tags, collects data from tag including anti-collision, controls and downloads PLL frequency synthesizer In frequency hop modes and other operations. A 22 MHz crystal resonator is used as the input clock signal for the microprocessor.

RFID Smart Device U-ways User Manual Page 11 of 14 Rev.1.0 7. TROUBLE SHOOTINGS Should the RFID Smart Device U-ways (reader) not work as desired, please check the following: a) Is the configuration of the reader as wanted? Check with help of the command V[v]. b) Is the configuration not known, are the baud rates of reader and terminal set different? Restore the basic setting of the parameters values with command D[d]. Now all parameter values are set to the default values, the reader will work in normal condition. c) Is the antenna defect or not properly connected? d) The transponder is not in the active antenna field. Bring the transponder closer to the antenna. e) Antenna mounting is wrong (for example behind a metal structure). In such a case, it can happen that the radiated power is reflected by unwanted plate in nearby metal structures. Please change antenna position. f) Although there is no transponder in the active antenna field. g) Noise from another radio equipment can also reduce the read range. You should try to remove all source of noise causing devices. Upper High Frequency fields radiated by other devices interfere with the reader communication: - power supplies, electrical motors, etc. Please remove such devices or remove the radiated interfering field by proper grounding if trouble takes place.
