USB Interfaces

The CP-RIO3-05 provides two identical USB interfaces implemented as a dual USB connector
J9 (USB0/USB1). Both interfaces provide a maximum transfer rate of 480 Mb/s for connecting
USB devices. One USB peripheral may be connected to each port. To connect more USB de-
vices than there are available ports, an external hub is required.

Note ...

The USB host interfaces on the CP-RIO3-05 rear I/O module can be used with
maximum 500 mA continuous load current as specified in the Universal Serial
Bus Specification, Revision 2.0. Short-circuit protection is provided. All the sig-
nal lines are EMI-filtered.

Note ...

The rear I/O interface supports the USB 1.1 and USB 2.0 standards.

When connecting peripheral devices to USB 2.0 ports, always ensure that
appropriate cables are used.
