DIGITUS DN-14001-2 Network Cable Tester with RJ-45 Connector, One-Sided Testing for Continuity, Cross-Connection, PoE, Shielding, and Short Circuits

The DIGITUS DN-14001-2 network cable tester is a specialized diagnostic device designed for efficient troubleshooting and maintenance of RJ-45 connections. This one-sided PoE tester enables comprehensive diagnostics, allowing technicians to verify cable integrity without needing access to both ends of the cable simultaneously. It supports continuity testing, cross-connection detection, PoE testing, shielding verification, and short circuit identification, making it an essential tool for local area network setups.

Advantages

The device provides reliable diagnostics for network installations by combining multiple testing functions into a single unit. Its one-sided testing capability significantly reduces time and effort during cable verification, especially over long distances. The robust housing offers effective shock and splash protection for field use, while low-voltage operation ensures safety for both users and sensitive network hardware. Clear visual indicators and low power consumption further contribute to efficient everyday operation.

Suitable for

• Testing RJ-45 network cables in office and residential environments
• Verifying cable integrity during local area network installations
• Identifying short circuits, cross-connections, and continuity issues
• Checking Power over Ethernet (PoE) availability on network lines
• Verifying cable shielding for STP and FTP cables

When it may not be suitable

This device is not designed for testing non-RJ45 cabling types such as coaxial or fiber optic cables. It may also not be optimal for complex industrial cable certification that requires detailed graphical reports beyond standard continuity and wiring checks.

Key specifications

• Supported connectors: RJ-45
• Test types: Continuity, cross-connection, PoE, shielding, and short circuit testing
• Cable compatibility: CAT 5, CAT 5e, CAT 6, and CAT 6A
• Power consumption: Low power operation, typically ≤ 0.5 W
• Design: One-sided testing with robust protective housing

How to use

Connect the RJ-45 network cable to the designated port on the tester. Initiate the test procedure using the device controls to check for continuity, wiring faults, or PoE status. Observe the LED indicators to interpret the test results regarding short circuits, crossed pairs, or shielding integrity. Use the one-sided testing feature when remote ends are inaccessible to quickly determine cable status.

What to consider before purchase

• Ensure your network infrastructure relies primarily on RJ-45 terminated cabling
• Verify whether one-sided testing capability matches your specific installation workflow
• Confirm compatibility with the category of cables you use, such as CAT 5, CAT 6, or shielded variants

Usage recommendations: Store the device in a dry environment away from extreme temperatures and moisture. Remove the batteries if the tester is not going to be used for an extended period to prevent potential leakage and maintain optimal operational readiness.
