RF MODULE Users Manal trademark: amroad model: RF-221 The RFID part is an ISO 14443A RFID reader/writer, It’s operating in the 13.56MHz ISM (Industrial Scientific Medicine) band for ISO 14443A RFID system. The circuit is comprised of a Micro Controller unit(MCU), 13.56MHz RF Transceiver circuit and aLOOP Antenna. Micro Controller Unit(MCU) The Control circuit controls all of RFID ASIC signals. Control circuit outputs the command data which is needed to work the Transceiver circuit. When the response data from the RFID ASIC circuit, it will proceed recognition and other procedure. RF Transceiver circuit (RFID ASIC). The signal of 13.56MHz is supplied from crystal oscillator. The Magnetic field signal is generated by the Transceiver circuit. This ASK modulation signal is supplied through the Impedance transformer and the Antenna matching circuit to the externalLOOP Antenna. The feedback signal sent from the tag is received at theLOOP Antenna and is input to The H.P.F. The signal is demodulated by the RF ASIC . LOOP Antenna The external LOOP Antenna is formed with the coil, and supplies the electric power and the transmission signal to the tag by generating the flux of magnetic fieldThe product can only be installed in the device which the model name conforms to the following wildcard characters : AABBBXR-YY-ZZ , and it must be installed by professionals. The host end product must also pass the FCC Part 15 unintentional emission testing requirement and be properly authorized per FCC Part 15. The instruction for series models of DB3101R-FM-BA as below : AABBBXR-YY-ZZ A - Application B - Number X - Version R - RFID Y - Installation Z - Color For example : DB3101R-FM-BA
