Does FC-C102E Fingerprint and Time Attendance Access Controller support an external fingerprint reader to open the door? How to connect it?
Hello, welcome to use our products, thank you for your support. FC-C102E/M Fingerprint and Time Attendance Access Controller supports the function of a master phone, you can connect a set of dedicated fingerprint heads to achieve linkage recognition for entry and exit. The fingerprint head power supply can be directly powered by the fingerprint access controller, the fingerprint head +12V is connected to the fingerprint access controller +12V (red wire), the fingerprint head RS485A is connected to the fingerprint access controller RS485A (gray wire), and the fingerprint head RS485B is connected to the fingerprint access controller RS485B (blue wire) , the fingerprint head GND is connected to the fingerprint access controller GND (black wire). (When the fingerprint access controller is used as a fingerprint head, it needs to be set to "slave mode", and the dedicated fingerprint head defaults to the slave mode, no need to set.)
