Full Product Description

Diagnose Network Issues in Seconds

Is your network speed fluctuating, or is a specific wall jack not working? Faulty cabling is often the invisible culprit. The Model LM-468 Network Cable Tester is the industry-standard solution for quickly identifying connectivity issues in CAT5, CAT6, and telephone lines.

 

Dual-Interface Testing Capabilities

Designed for versatility, this tester supports both RJ45 (Ethernet) and RJ11/RJ12 (Telephone) connectors. It is the perfect companion for setting up home offices, installing CCTV systems, or troubleshooting business networks. It automatically scans for open circuits, short circuits, and crossover wiring mistakes (mismatched pins).

 

Detachable Design for Long-Distance Testing

Cables are rarely sitting in a pile; they run through walls, ceilings, and under floors. This unit features a detachable Remote Master, allowing you to test a cable even if the two ends are in different rooms (up to 1,000 ft apart). simply plug one end into the Master unit and the other into the Remote unit, and watch the LED indicators verify the pinout sequence.

 

Visual LED Status Indicators

No complex screens or menus. The device uses a clear, 1-to-8 LED light sequence to visualize the connection status of each wire in the twisted pair.

  • Straight-through: Lights sequence 1 through 8 in order.
  • Cross-over: Lights jump order (indicating a crossover cable).
  • No Light: Indicates a broken wire or open circuit.

Note: This device requires a standard 9V battery to operate. Click here to add a GP Supercell 9V Battery to your order so you can start testing right out of the box.

FAQ Section

Q: Can this tester tell me the speed of my internet (e.g., 1Gbps)?
A: No, this is a continuity tester. It verifies that the physical wires inside the cable are connected correctly and not broken. It ensures the cable can carry data, but it does not measure bandwidth speed.

Q: Does it work with shielded (STP) cables?
A: Yes, the unit includes a "G" (Ground) LED indicator. If you are testing a shielded RJ45 cable, the G light will illuminate to confirm the shielding continuity.

Q: Is the battery included in the box?
A: The manufacturer packaging does not include a battery. You will need a standard 9V battery. You can purchase a high-quality 9V battery here.
