C2G CG39002 – LANsmart TDR Cable Tester for Cat5 Cat6 UTP STP

Product Overview

The C2G CG39002 LANsmart TDR Cable Tester is a professional-grade structured cabling diagnostic tool for AV integrators, IT technicians, and facilities managers. Using Time Domain Reflectometer (TDR) technology, it detects, locates, and displays wiring faults — opens, shorts, miswirings, reversals, split pairs, and shield continuity — in RJ45, Cat5, Cat6, UTP, and STP cable. It also measures cable length without a remote unit, making it a standalone field tool for commissioning and troubleshooting structured cabling in conference rooms, data centers, and commercial AV installations.

Product Description

The LANsmart displays test results in a pin-to-pin format for clear fault identification. TDR technology allows the tester to measure cable length and locate fault positions in real time without a remote terminator at the far end — useful for testing installed cable before termination or when a remote unit is unavailable. A built-in tone generator sends signals to selected pins or all conductors for cable tracing with a compatible tone probe (probe sold separately). The tester also supports auto-negotiation signal output for live network port identification and PoE detection.

The CG39002 is designed for commercial AV and IT environments where structured cabling verification is a routine part of system commissioning and post-installation certification. Results are displayed on a clear pin-to-pin diagram, showing pass/fail status for each conductor pair with fault type identification.

Key Features

• TDR Cable Length Measurement — Measures UTP and STP cable length without a remote unit using Time Domain Reflectometer technology in real time.
• Fault Detection and Location — Identifies and locates opens, shorts, miswirings, reversals, split pairs, and shield continuity faults.
• Pin-to-Pin Display — Results shown in pin-to-pin format for clear, actionable fault identification across all conductor pairs.
• Built-In Tone Generator — Sends tone signals to selected pins or all conductors for cable tracing with a compatible tone probe (probe not included).
• Auto-Negotiation Signal Output — Outputs auto-negotiation signals to identify live network ports and detect PoE presence.
• Compatible Cable Types — Tests RJ45, Cat5, Cat6, UTP, and STP cable types.
• Standalone Operation — Tests cable length without requiring a remote unit at the far end.

Typical Applications

• Structured cabling verification during commercial AV system commissioning
• Conference room and AV equipment room cable fault diagnosis
• Pre-termination cable length measurement for conduit runs
• Data center and server room cabling certification
• Post-installation network cable troubleshooting
• AV-over-IP infrastructure cable verification

Frequently Asked Questions

Can this tester measure cable length without a remote unit?

Yes. TDR technology allows the CG39002 to measure cable length in real time without a remote terminator at the far end — useful for installed cable before final termination.

Is a tone probe included?

No. The tone probe is not included. The built-in tone generator is compatible with standard tone probes available separately.

What faults can it detect?

The CG39002 detects opens, shorts, miswirings, reversals, split pairs, and shield continuity faults across RJ45, Cat5, Cat6, UTP, and STP cable types.

Can it detect PoE on live network ports?

Yes. The auto-negotiation signal output function detects PoE presence on live network ports.
