EM-18 RFID Reader

EM18 RFID Reader is a module which reads the ID information stored in RFID TAGS. This ID information is unique for every TAG which cannot be copied.

EM-18 Pin Configuration

EM-18 is a nine pin device. Among nine pins, 2 pins are not connected, so we basically have to consider seven terminals.

VCC — 5V

GND — Ground

Buzz/Beep — Beep and LED

SEL — HIGH means RS232, LOW means WEIGAND

TX — Transmitter

DATA1 — WEIGAND DATA 1

DATA2 — WEIGAND DATA 0

EM-18 Features and Specifications

• Operating voltage of EM-18: +4.5V to +5.5V
