Guidelines for USB Cables

Keep the following guidelines in mind when connecting USB cables:

• Always use USB 2.0 compliant, fully rated (480 Mbit/sec) 20/28 AWG cables for connecting USB 2.0 devices.

• Always use USB 1.0 compliant, fully rated (12 Mbit/sec) 20/28 AWG cables for connecting USB 1.0 or 1.1 devices. Use bus-powered hubs for low-speed devices only. Always use fully rated (12 Mbit/sec) 20/28 AWG cables for connecting USB devices.

• Maximum cable length that is supported is 5 meters.

• Do not use cable extenders. For best results, use a self-powered hub to extend cable length.
