Quick Guide: Choosing a USB Extension Cable for Your Setup

Tested and recommended cables

• Unitek Y-3004 USB 3.0 Extension Cable

• Unitek Y-277 USB 2.0 Active Extension

General rules about cable use:

1. Length Matters

   • Up to 3 m (around 10 ft) for USB 3.0, 5 m (about 16 ft) for USB 2.0.
   • For longer distances, choose an active cable with built-in signal boosters.

2. Passive vs. Active

   • Passive Cables: Best for short runs (2–3 m / 6–10 ft).
   • Active Cables: Have electronics that amplify the signal, ideal for distances beyond 3–5 m (10–16 ft).

3. Matching USB ports

   • Match the cable type (USB type A, USB-C 2.0, 3.0, etc.) with your device’s USB port for optimal data transfer.

4. External Power Option

   • If you connect multiple sensors or devices, an active cable with a power cable can ensure stable voltage and reduce data errors.
   • If you use active USB extention cable with a power cable, make sure you plugged both cables.

5. Other Tips

   • Prioritize cables from reputable brands. Some camera models may have recommended cables to use.
