Details of the problem:

Hello, the distance between the card reader and the control board is about 40 meters, the card reader has no Wiegand signal output, when it is connected to the control board reader terminal, the card number is output when the card is swiped, is there any solution?

Expert answer:

Hello, you remove the card reader and connect it directly to the terminal of the reader head of the control board without wiring. Then swipe your card. If the card data is normal, the device is intact. Therefore, it is judged that the line is interfered, and it is recommended to check the line interference problem. If the interference can be ruled out, this is still the case when the card reader is connected, please replace the card reader.
