   "description": "Specifications Check cable connections - Check whether the cable heads are arranged correctly and check for cable breaks Suitable to use with RJ45 RJ11 RJ12 Twisted Pair Connection CAT5/CAT6/CAT7,Telephone cable (RJ11, RJ12) Main tester: 1-2-3-4-5-6-7-8-G Remote tester: RJ45 1-2-3-4-5-6-7-8-G 1-2-3-4-5-6 RJ11 Durable Easy to use What the numbers mean Normal cable (straight-through CAT5/CAT6): LEDs on the Main and Remote units should light up in order 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8. Cross-over cable: LEDs still all light up, but the order may cross (e.g. pin 1 on one side goes to pin 3 on the other). Faulty cable: Open (broken wire) → that number won’t light up at all. Short (two wires touching) → two LEDs may light together or out of order. Mis-wire → LEDs sequence doesn’t match pin-to-pin. How it works You plug one end of the cable into the Main unit and the other end into the Remote unit. When you turn it on, LEDs labeled 1–8 (and sometimes “G” for ground/shield) light up in sequence. Each number corresponds to one conductor inside the cable: 1 → Pin 1 2 → Pin 2 … up to 8 → Pin 8 G → Ground/Shield (only relevant for shielded Ethernet cables, e.g. STP or FTP). Tips Use Slow mode to see the blinking lights more clearly. Use Fast mode when you need to quickly check multiple wires.
