6.  Once the ethernet wire is routed through the conduit leading to the Communication Module, carefully strip this       

end of the et hernet cable approximately 4 inches, ensuring none of the twisted pair conductors are damaged in this    

process. 

7.  Strip the ends of all 4 twisted pairs approximately 5mm (1/4 inch). 

8.  Wire the green twisted pair to pins 1 and 2 of the J2 connector on the Communication Module, the green wire 

connected to pin 1 and the white/green wire connected to pin 2, table shown in Figure 11. 

9.  Wire the blue twisted pair to pins 3 and 4 of the J2 connector on the Communication Module, the blue wire 

connected to pin 3 and the white/blue wire connected to pin 4. The drain wire should be connected to pin 4 along 

with the white/blue wire.
