Product information

Description

Universal Tester OEM 5558 is a compact network and cable tester designed to verify the connectivity and wiring integrity of RJ12 and RJ45 telephone and Ethernet cables, USB ports and BNC coaxial connections. The device checks continuity, detects open and short circuits, and indicates wiring status to help technicians confirm proper pin-to-pin connections and identify common wiring faults before installation or during maintenance.

Advantages

The tester is small and portable, allowing for convenient on-site diagnostics and rapid troubleshooting. It supports multiple connector types—RJ12, RJ45, USB and BNC—so a single tool covers a range of cable and port checks. The device provides clear pass/fail indications and wiring fault detection, enabling efficient verification of cable continuity and identification of opens or shorts without complex setup.

Suitable for

Field technicians performing cable installation checks
IT staff validating Ethernet and telephone cabling
Audio/video technicians testing BNC coaxial links
Maintenance teams troubleshooting USB ports and network outlets

Key specifications

Supported connectors: RJ12 (6P), RJ45 (8P), USB type-A, BNC coaxial
Test functions: continuity check, open circuit detection, short circuit detection
Display/indication: visual indicators for wiring status and faults
Power: battery-powered portable unit (standard replaceable battery)
Form factor: handheld, compact housing for field use

How to use

Connect one end of the cable or the port under test to the appropriate jack on the tester and, if required, the remote end to the corresponding remote adapter or receiver. Power the unit on and observe the visual indicators while the device performs the check. Interpret the results according to the indicator pattern: a complete continuity indication denotes correct wiring, while open or short indications point to wiring faults that require inspection or retermination. For USB and BNC checks, use the matching port and follow standard safety precautions when testing live equipment.

Usage recommendations

Store the tester in a protective case when not in use, replace batteries before long deployments, and verify connectors are clean and undamaged prior to testing. Use the device in dry conditions and avoid exposing it to extreme temperatures to ensure reliable measurements.
