SML-QTS Multifunction Cable Tracer and Tester
For RJ45 single-ended checks, wire mapping, and tracing fully de-energized network, telephone, or coaxial cables.

- Standalone RJ45 single-ended testing with the receiver; starts automatically after insertion
- The LCD identifies specific faulted conductors when a single-ended check fails
- Tracing up to 500 m for RJ45 network cable and 300 m for RJ11/two-conductor or BNC coaxial cable
Combines RJ45 single-ended testing, network/telephone/coaxial tracing, and two-ended RJ45 wire mapping, with a 0.96-inch LCD on the receiver.
Product Overview
The SML-QTS consists of a transmitter and a receiver with a 0.96-inch LCD. It is designed for structured cabling, low-voltage maintenance, and line identification. The receiver can independently check the inserted RJ45 termination. Used together, the transmitter and receiver can trace network, telephone, or coaxial cable and perform two-ended RJ45 wire-map and continuity checks.
Single-ended testing and wire mapping display automatically. After an RJ45 plug is inserted into the shared test/wire-map port at the bottom of the receiver, no separate wire-map position or button is required. During tracing, use the displayed signal strength, buzzer rate, and sensitivity setting together. Muting the buzzer does not affect the on-screen signal-strength reading.
Typical Applications
- Quick single-ended checks after making or re-terminating an RJ45 cable
- Verification of 2–8 conductor order, opens, shorts, and crossovers after both ends are terminated
- Identification of a target network cable in patch panels, low-voltage shafts, or cable bundles
- Location of RJ11 telephone/two-conductor cable or BNC coaxial cable
- Direct transition from tracing the far end to two-ended RJ45 wire mapping
Package Contents
The standard package includes the transmitter, receiver, carrying pouch, color box, USB Type-C charging cable, RJ11 alligator-clip lead, and certificate/warranty card. Check the actual package after opening.
Functional and Safety Boundaries
Single-ended testing accepts RJ45 network plugs only and does not replace two-ended testing of the complete cable. RJ11 telephone cable and BNC coaxial cable are supported for tracing only. Wire-map results do not certify data rate, attenuation, crosstalk, shielding performance, or link category.
The product includes PoE port-misconnection protection intended only to reduce the risk of accidental equipment damage; it does not permit energized testing. Before connection, tracing, single-ended testing, or wire mapping, completely disconnect the cable from switches, PoE equipment, telephone equipment, and every other device or power source.
