EM-18 RFID Reader Module

600.00 569.00

EM-18 RFID Reader is one of the commonly used module for Radio Frequency Identification Projects. It can be directly interfaced with a microcontrollor using UART communication and with a PC using a RS232 converter. This module can work with any 125KHz RFID tags and it can provide UART / Wiegand26 output formats. Pitch of output pins are 2.54mm, thus it can be directly inserted to a breadboard for project developing.

Note

  • E – Summed for Even Parity
  • O – Summed of Odd Parity
  • P – Parity (Even or Odd)
  • D – Data Code for Card

UART Interface

  • TX Output : 10 ASCII Data (Card No.) + 2 ASCII DATA (XOR Result)
  • Baud Rate : 9600bps
  • Data Bits : 8 bits
  • Parity : None
  • Stop Bit : 1

For eg : If the RFID tag number is 500097892E, output of EM-18 Reader will be 500097892E60 where 60 is 50 xor 00 xor 97 xor 89 xor 2E.
