Testing RJ12 6 Conductor Phone Cables
Phone cables are connected from Pin to Pin on the opposite end, 2-2, 3-3, and so forth. See diagram.
When testing RJ12 phone cables: Tester will test each pin sequentially. Green LED will illuminate for phone cables
starting at pin 1 and ending at pin 8. Cable is GOOD when all green LED’s light up in sequential test order:
Pin 1, Pin 2, Pin 3, Pin 4, Pin 5, Pin 6
Note: Pin 7, 8, G will not illuminate for RJ12 cables.
If an LED does not light up, pin connection is bad.
If LED lights up in wrong order, I.E.
Pin 1, Pin 2, Pin 4, Pin 3, Pin 5, Pin 6, this would indicated a crossed connection at Pin 3 and 4.
