![]() ![]() Operating voltage of EM-18: +4.5 V to +5.If the baud rate mismatches you will get some garbage output on your terminal. The default baud rate of this module is set to 9600 bps (bits per second), Use the same baud rate to retrieve information. Among nine pins, 2 pins are not connected, so we basically have to consider seven terminals. ![]() EM-18 Pin Configuration EM-18 is a nine pin device. This ID information is unique for every TAG which cannot be copied. I am going to use RS232 here because of its popularity. EM18 RFID Reader is a module which reads the ID information stored in RFID TAGS. If the SEL pin is set to HIGH the communication medium will be RS232 (UART) and if the SEL pin is pulled down to LOW the communication medium will be WEIGAND. It can be selected by setting the logic output on the SEL pin of EM-18. EM-18 RFID Reader can provide output via two communication methods "RS232" and "WEIGAND". As you know RFID Library for Proteus is not available yet, so I found a way to simulate it using a virtual terminal.īefore Starting, I will share some details about the EM18 RFID Reader based on UART Communication. When an RFID card comes in the range of the reader, the unique data in the card is. ![]() Hello Guys, In this simulation tutorial, I will help you to simulate an RFID reader in Proteus with Arduino UNO. EM18 RFID reader module is used to read RFID cards that work at 125 kHz. ![]()
