SML-DSL-IP+ Professional IP Network Multifunction Cable Tracer
For cable maintenance and IP/network diagnostics on networks you own or are explicitly authorized to test.

- Integrated cable tracing and 2-to-8-conductor remote wire mapping
- TDR length testing with 0.1 m resolution and a 500 m maximum range
- Measures PoE output voltage and identifies standard or non-standard power
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.
The product image shows the general series appearance. The panel and interfaces vary by model; refer to the corresponding unit.
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
Packing and Accessories
This model includes one transmitter, one receiver, one two-core receiver head, one network-cable receiver head, one two-core alligator clip/RJ11 alligator adapter lead, one USB charging cable, one certificate, one warranty card, one manual, one work bag, and one color box. IP and network tests do not require a dedicated accessory.
Use and Safety Limits
For length testing, the cable must be de-energized and its far end left open; never connect a PoE-powered cable to the length-test port. PoE, IP, and network tests share the same RJ45 port, and that port is for wired Ethernet cable only; the maximum permitted PoE test voltage is 60 V. This model does not support tracing 220 V in-wall or underground cables. Do not connect mains power, telephone lines, or lines of unknown voltage. Use IP scan, HTTP, network sniffing, and broadcast monitoring only on networks that you own or are authorized to test. LLDP results depend on peer-device support and configuration.
