3. Wiring Instructions 
The units are supplied with a 10-conductor 18” (46-cm) pigtail or with 
10 terminal blocks. 
To connect a pigtail reader to the controller: 
1. Prepare the reader cable by cutting its jacket back 3.2 cm (1¼”) 
and strip the insulation from the wires 1.3 cm (½"). 
2. Prepare the controller cable by cutting its jacket back 3.2 cm (1¼") 
and strip the insulation from the wires 1.3 cm (½"). 
3. Splice the reader’s pigtail wires to the corresponding controller 
wires (as indicated in Table 1) and cover each joint with insulating 
tape. 
4. If the tamper output is being utilized, connect the purple wire to 
the correct input on the controller. 
The LED control may be configured by the factory to function 
either as a LED control or as buzzer control. Currently, the auxiliary 
input is used as buzzer control and LED Control 1 is used as the 
green LED control. 
5. Trim and cover all unused conductors.

• 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 power supply 
end of the cable.

4. OSDP Operation 
The K and L models do not currently support OSDP function. 
CSN SELECT readers that support OSDP operation are compatible with 
most OSDP commands. The reader address is set using DIP switches on 
the back of the reader. Release the screw on the back of the reader to 
remove the door to access the DIP switches. 
Figure 1 shows the DIP switch settings, which are described below. 
Figure 1: DIP Switch Settings 
 DIP Switch 1 
This switch is used to select the reader output (Wiegand or OSDP): 
 Off = Wiegand 
 On = OSDP 
 DIP Switch 2 
This switch is reserved for future use. 
 DIP Switch 3 
This switch is reserved for future use. 
 DIP Switches 4 to 8 
These switches set the address of the reader for OSDP protocol. 
DIP Switch 4 is MSB and DIP Switch 8 is LSB. The address is the DIP 
switch state +1. 
Examples: 
 All the DIP switches in Off position, state is = 0 => address = 1 
 All the DIP switches in On position, state is = 0x1F => address 
= 0x20 = 32 
DIP switches 4, 6, 8 in On position and 5, 7 in Off position, state is 
= 0x15 => address = 0x16 = 22
