What’s included and how it helps

This starter kit combines the trusted Scout Pro 3 tester with multiple remotes to map and identify cable runs across different media. Use it to confirm cable terminations and trace paths without guesswork.

• Tests voice (RJ11/12), data (RJ45), and video (coax F-connector) terminated cables with clear results.
• Measures cable length up to 2000 feet (610 m) so you can determine run sizes at a glance.
• Detects Open, Short, Miswire, and Split-Pair faults for thorough fault identification.

To simplify installation workflows, the kit reads test results on a backlit LCD display, shows wiremaps and cable IDs, and supports cable tracing with a compatible tone generator. The hub blink mode helps you locate port positions on a hub or switch, speeding network setup or troubleshooting tasks.

• Backlit LCD display shows cable length, wiremap, cable ID, and test status in various lighting conditions.
• Trace cables and individual conductors with an optional tone generator (analog probe required: VDV500-123).
• LanMap and CoaxMap Location Remotes (5 each) enable multi-cable run mapping in a single step.
