I have situation where I need to read RFID cards. There is already installed Roger security system, Roger gate control board and two rfid readers in parallel. By default board and RFID readers communicate in RACS(some sort of coded protocol) but at the moment system is configured to communicate in Wiegand26. Earlier I used chinese wiegand26 reader with Arduino with no problem.
With Arduino I need to read card read by RFID readers. Then I process data and make HTTP POST request. Arduino is supplied from Roger board ~13.5V DC I do not get anything in arduino, even if I connect RFID readers directly to arduino.
- CLK is D0 to Arduino Nano pin 2
- DTA is D1 to Arduino Nano pin 3
This question is not related only to Arduino.
I want to ask is it possible to do? To read data maybe I need some additional electronics?
What i also noticed that when Arduino is connected in parallel the Roger board not always reads the card from RFID readers.
