Wiring
The units are supplied with a 5 m (16.4 ft) 10-conductor pigtail with exposed wires
coated with solder (see Figure 5).
Figure 5: Wiring Colors
To connect the unit as a reader to an access control unit:
1.
Select the appropriate connections according to Table 1.
2.
Prepare the controller cable by cutting its jacket back about 3 cm (1¼") and
strip the insulation from the wires about 1.3 cm (½").
3.
Splice the reader’s pigtail wires to the corresponding controller wires and cover
each joint with insulating tape.

4.
Trim and insulate the ends of all unused conductors individually. Do not short
any unused wires together.
•
The individual wires from the reader are color coded according the Wiegand
standard.
•
When using a separate power supply for the reader, this supply and that of the
controller must have a common ground.
•
The reader’s cable shield wire should be preferably attached to an earth ground, or
a signal ground connection at the panel, or the power supply end of the cable. This
configuration is best for shielding the reader cable from external interference.
