USB Interfaces

The CP6500-V supports four USB 2.0 ports (two on the front I/O and two on the rear I/O). On
the two rear I/O ports it is strongly recommended to use a cable below 3 metres in length for
USB 2.0 devices. All four ports are high-speed, full-speed, and low-speed capable. High-speed
USB 2.0 allows data transfers of up to 480 Mb/s - 40 times faster than a full-speed USB
(USB 1.1).
One USB peripheral may be connected to each port. To connect more than four USB devices
an external hub is required.
The USB power supply provides 500 mA continuous load current and 900 mA short-circuit
protection.
