Dual-Purpose Diagnostics: CPJ-468USB RJ45 + USB Cable Tester
The CPJ-468USB Computer Network Cable Tester is a versatile diagnostic solution designed for modern IT environments that rely on both high-speed networking and USB data connections. This specialized tool allows you to quickly verify the wiring integrity of RJ45 Ethernet cables and various USB data cables, ensuring your hardware is connected correctly and efficiently.
Engineered for practical field use, the tester features a detachable Master and Remote unit system. This design is perfect for testing cables that are already routed through walls, ceilings, or furniture, allowing a single technician to perform end-to-end continuity checks without moving heavy equipment.

-
Dual Testing Support: Specifically designed to test RJ45 (8P8C) networking cables and USB data cables for proper pin mapping.
-
Detachable Remote Unit: The Master and Remote units slide apart, enabling convenient testing of long-distance or pre-installed cabling.
-
Visual LED Feedback: Features sequential LEDs (1-8 plus Ground) on both units to clearly indicate successful connections, crosses, or open circuits.
-
Adjustable Speed Control: A 3-position power switch (OFF / ON / S) includes a "Slow" mode to help identify intermittent faults or rapid sequence errors more easily.
-

Top 3 Customer Questions & Concerns
-
Can this tester identify the exact distance to a cable break?
-
No, the CPJ-468USB is a continuity and mapping tester; it shows which pins are disconnected but does not provide a physical distance measurement.
-
-
Is it safe to use this on a live "PoE" (Power over Ethernet) line?
-
This tester is designed for unpowered, "dark" cables only; connecting it to a live PoE switch may damage the sensitive LED diagnostic circuitry.
-
-
Why would I use the "S" (Slow) mode?
-
The slow mode is helpful for catching "crosstalk" or temporary shorts that might flash too quickly to see during a standard high-speed test.
