2. Functional Description
2.1 Board Interfaces
2.1.1 USB Interfaces
The CP-RIO6-001/-DD-216/-HD/-HD-216 rear I/O module supports three USB 2.0 ports, two
on the front I/O and one onboard for the USB NAND Flash module. All ports are high-speed,
full-speed, and low-speed capable. One USB peripheral may be connected to each port. For
connecting more USB devices to the CP-RIO6-001/-DD-216/-HD/-HD-216 than there are
available ports, an external USB hub is required.
2.1.1.1 Front Panel USB Connectors J6 and J7
On the front panel of the CP-RIO6-001/-DD-216/-HD/-HD-216 rear I/O module, there are two
USB interfaces implemented on two 4-pin connectors with the following pinout:
Note ...
The USB host interfaces 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 a function of the CPU board used with this rear I/O
module. All the signal lines are EMI-filtered.
Note ...
The rear I/O interface supports the USB 1.1 and USB 2.0 standards. For USB
2.0 it is strongly recommended to use a cable length not exceeding 3 meters.
