# 6 Mounting Hardware 

 

5-conductor shielded cable; 22 AWG wire 

 

Extension Kit (Optional) 

 

STEP 1: MOUNT THE RECEIVER 

Mount receiver to surface using #6 hardware (not 
supplied).  Refer to Figure 8 for receiver mounting 
hole locations. 

NOTE:

 Mount receiver with 18” of space above 

the receiver for the antenna.  Also, receivers 
should be installed at least 5 feet apart to 
avoid “cross-talk”. 

 

STEP 2: CONNECT THE ANTENNA 

Screw on antenna clockwise and slide rubber boot 
down to meet o-ring (see Figure 7)
 

CAUTION 

The outside of the antenna connector is not 
ground.  If using an extension kit, do not allow it 
to contact a metal object.

STEP 3: CONNECT SIGNAL/POWER WIRES 

Remove the terminal block from J2 on the circuit 
board.  Connect wires from the CPWR 6-pin 
connector to the access control system.  Refer to 
Figure 8.  Then re-insert the terminal block onto J2. 
 
Wire the CPWR to the access control systems’ 

card reader

 port.  Refer to the access control 

system’s installation instructions for appropriate 
wiring detail.  A 

typical

 wire connection might 

resemble the following:
