The D-Link NTL-CT-001 is an essential tool for network professionals and home users who need to diagnose and verify Ethernet cabling. This two-piece unit (main tester + remote) uses an automatic scan mode to rapidly test cables, displaying the status of each individual wire via dedicated LEDs on both units .
Key use cases include:
Pre-installation verification: Testing new cable runs for continuity before connecting hardware .
Troubleshooting: Identifying breaks (opens), electrical shorts, or mis-pinned crossed wires in faulty cables .
Slow Test Mode: Moving the switch to "S" mode slows down the scanning, allowing for detailed visual inspection of each wire pair .
Note: The device requires a standard 9V battery (not included) and is available in Bangladesh through retailers like Rokomari and Onix Computer Systems .
