SML-DSL-IP+ Professional IP Network Multifunction Cable Tracer
Cable tracer with 0.1 m-resolution TDR length testing, PoE checks, and all nine professional IP/network functions.

Product Overview
The SML-DSL-IP+ is the professional IP+ edition with 0.1 m-resolution TDR length testing. It reports twisted-pair length by pair and combines all nine IP/network functions with cable tracing, remote wire mapping, PoE checks, and multi-cable tracing.

IP / IP+ Feature Editions
| Network function | IP entry edition | IP+ professional edition |
|---|---|---|
| IP scan | Supported | Supported |
| PING | Supported | Supported |
| Port blink | Supported | Supported |
| Link speed | Supported | Supported |
| IP monitoring | — | Supported |
| HTTP test | — | Supported |
| LLDP | — | Supported |
| Network sniffing | — | Supported |
| Broadcast monitoring | — | Supported |
IP configuration is a shared setup function used by both editions and is not counted as a separate feature tier. Choose the SML-DSL-IP when only the four entry network functions are required.
Typical Applications
- Locating network cables and diagnosing wire-map, continuity, and length faults
- Measuring twisted-pair cable and pair length
- Checking PoE port voltage and power type
- Inspecting IPv4 reachability, addresses, links, neighboring devices, and broadcast conditions
- Tracing telephone lines, two-core wires, and coaxial cable
Use and Safety Limits
For length testing, the cable must be de-energized and its far end left open. This model does not support tracing 220 V in-wall or underground cables. Never connect it to mains power or an unknown high-voltage circuit. The maximum permitted PoE test voltage is 60 V. Use IP scan, HTTP, network sniffing, and broadcast monitoring only on networks where you have authorization. LLDP results depend on peer-device support and configuration.
Features
