1. Connect the device to power:
Red wire → +12V
Black wire → Ground
Once connected, the device will power on.
2.Using a multimeter to check the signals:
Set the multimeter to DC voltage mode.
(a) To check Wiegand Out D0 (DO):
· Connect the red probe of the multimeter to the Wiegand Out D0 wire.
· Connect the black probe to the Wiegand Ground wire.
· The voltage should read between 4–5V.
(b) To check Wiegand Out D1 (D1):
· Connect the red probe to the Wiegand Out D1 wire.
· Connect the black probe to the Wiegand Ground wire.
· The voltage should also be between 4–5V.
