SML-DS Multifunction Cable Tracer
Portable field tracer combining network-cable tracing, remote wire mapping, PoE checks, and two-core and coaxial cable tracing.

Product Overview
The SML-DS is the base model in the SML-DS Series, designed for structured cabling, communications maintenance, and security wiring inspection. It combines network-cable tracing, remote wire mapping, and PoE checks in a transmitter-and-receiver kit and can also trace telephone lines, two-core wires, and BNC coaxial cable. The receiver’s color display presents signal strength, wire map, and device status for efficient everyday field work.
The product image shows the general series appearance. The panel and interfaces vary by model; refer to the corresponding unit.
Typical Applications
- Locating target network cables at patch panels, switch ports, and wiring closets
- Diagnosing wire order, continuity, open, short, and crossover faults
- Checking PoE port voltage and power type
- Tracing telephone lines, two-core wires, and coaxial cable
Use and Safety Limits
Connect a PoE cable only to the dedicated PoE test port; the maximum permitted test voltage is 60 V. The coaxial port is for tracing only, not length or continuity testing. This model does not support length testing or tracing 220 V in-wall or underground cables. Never connect it to mains power or an unknown high-voltage circuit.
Features
- Integrated cable tracing and 2-to-8-conductor remote wire mapping
- Measures PoE output voltage and identifies standard or non-standard power
- Automatic and manual tracing modes with 0-to-10 manual sensitivity levels
- Traces telephone lines, two-core wires, and BNC coaxial cable
- 2.4-inch color receiver display with Chinese and English interfaces
