Review on LIBO Biometric Fingerprint Controller Standalone by Dan Reggae
Three different wiring diagrams, none working
I've tried every possible combination of wiring to get fingerprint or RFID scanners to unlock my electromagnetic locks but nothing works. As soon as I connect the push wire to ground, the latches work as usual. This means that everything is connected correctly, but the access control is not working. I know my fingerprint and an RFID tag have been scanned correctly because when I try another finger or tag the red light flashes along with a long beep. I tried changing the unlock mode between 6 seconds and 500ms, no change. I'm not sure what else to do as I can't think of anything else I'm doing wrong!
