Installing an External Door Security Reader
Figure HARDWARE-7: Wiegand Connector
2. The connections on the Wiegand port are (from left to right)
“Data1,” “Data0,” “Ground,” and “VCC (Power).” See page 185
for a table detailing which colored wires are to be installed into
which ports.
3. Connect the data wires into the screw terminals.
4. On the “Ground” wire, twist the black and shield wires together and
insert into the appropriate terminal.
5. Finally, connect the red power wire.
Note: Boards with 3-terminal Wiegand connectors will still func-
tion when connected to the clock, but must be connected it an exter-
nal power supply. 4-terminal clocks are capable of powering the
reader with no external connections beyond the clock and reader.
Once the door security unit has been connected you can re-mount the
clock on the wall and re-connect its data and power cables.
