Here is the circuit diagram of the cable tester.
The cable tested is designed to test 568A and 568B data cables and USOC voice cables.
The design caters for a Master unit and a Remote. The master containers the driver and the battery (9V). The remote has 4 Red and 4 Green LEDs. This will give an indication of continuity or cross over.
