EM18 – 125Khz RFID Reader Module
EM-18 is a nine pin device. Among nine pins, 2 pins are not connected, so we basically have to consider seven terminals.
| Pin Number | Description |
| VCC | Should be connected to positive of power source. |
| GND | Should be connected to ground. |
| BUZZ | Should be connected to BUZZER |
| NC | No Connection |
| NC | No Connection |
| SEL | SEL=1 then o/p =RS232 SEL=0then o/p=WEIGAND |
| TX | DATA is given out through TX of RS232 |
| DATA1 | WEIGAND interface DATA HIGH pin |
| DATA0 | WEIGAND interface DATA LOW pin |
