Cable and PoE Tester VALUE LANtest Multi-Network Cable + PoE Tester, model 13.99.3003

VALUE LANtest Multi-Network Cable + PoE Tester (model 13.99.3003) is a handheld tester designed to verify the integrity of multi-network cabling and detect the presence of Power over Ethernet (PoE). The device performs continuity testing for coaxial cables with BNC connectors and for 8‑pole data lines with fitted RJ‑45 connectors. It helps identify open circuits, short circuits (wire-to-wire or wire-to-shield) and shows wiring pairs using a sequential LED/line display. Two RJ‑45 sockets and supplied adapter cables make it possible to test installed cables using remote units, while the integrated PoE check quickly indicates if a cable is carrying power.

Advantages

The tester provides clear visual feedback through a two-line LED display that sequentially indicates which pin at cable end A corresponds to which pin at cable end B, and it supports manual or automatic step-through. Short-circuits are indicated by multiple LEDs lighting simultaneously. Two RJ‑45 sockets plus supplied BNC-to-RJ‑45 adapter cables enable both data and coax testing. The dedicated PoE finder gives an immediate LED indication of power presence on a network cable, simplifying verification tasks on site. The tool is battery-powered for portable field use.

Suitable for

• Installation and verification of Ethernet cabling (RJ‑45)
• Testing coaxial runs with BNC terminations
• Troubleshooting open circuits and short circuits in network cables
• Checking PoE availability on existing network drops
• On-site maintenance and commissioning of network outlets using remote kit cables

Key specifications

• Continuity testing for coaxial (BNC) and 8‑pole RJ‑45 cables
• Detection of open circuits and short circuits (wire/wire and wire/shield)
• Two-line visual display (LEDs) indicating pin mapping and short-circuit status
• Manual and automatic stepping through pin sequence
• Two RJ‑45 sockets and remote kit compatibility for in-wall testing
• Includes two BNC-to-RJ‑45 adapter cables for coax testing
• PoE finder with instant LED indication of voltage presence on cable
• Battery power: requires one 9 V E-block (not included)

How to use

Connect one end of the cable under test to the main unit and the other end to the remote unit or the second RJ‑45 socket on the tester. For coaxial cables, use the supplied BNC-to-RJ‑45 adapter cables. Switch the tester on and select the desired mode; the two-line LED display will indicate sequential pin mapping or show simultaneous LEDs if a short-circuit is present. For PoE checking, plug the network cable into the PoE finder input—if the cable carries power the PoE LED will light instantly. Replace the internal 9 V battery when the power indicator shows low voltage to ensure reliable measurements.

Usage recommendations

Use the remote kit cables provided to test wall-mounted or in-wall terminations without disconnecting installed equipment. When testing live network drops for PoE, exercise standard safety precautions; do not attempt to open or repair energized connectors. Store the tester and adapters in a dry, dust-free environment and remove the battery during long-term storage to prevent leakage.
