EM9916 - 125khz RFID RS232 Reader

  Product Description General Features:                       125KHz carrier frequency        . An RFID reader system Reading of amplitude-modulated transponders   Include A 10-cm diameter square antenna                                                   An external DC 9V voltage that provides Easy to build up a control system                                                        0.2A current power supply is needed. The card with EM format is needed Product specification : 1) Power supply : DC12V, 200mA . 2) Reading range : 12-15CM  3) Reading speed: less then 70mS .  4) Frequency: 125KHz carrier frequency .   5) Operating Temperature:0 to 55°C  6) Storage Temperature: -25 to 65°C  7) Humidity:5-95%RH   Note: This reader is supplied in a PCB board containing RF circuits, an 8-bit microcontroller and data output connections. Its main functions are driving the antenna, sending demodulated data into microcontroller, checking the input data code and processing output data format.   The following is Data Connection of Reader:
