Block-circuit diagram of the CPCI-USB-5
The CPCI-USB-5 is a CompactPCI
®
board in 3U format. It is equipped with a NEC µPD720101, a
USB 2.0 host controller that supports 5 Hi-Speed USB 2.0 interfaces. One of them is multiplied by
an on-board HUB.
The 5 external USB 2.0 interfaces are accessible via USB connectors (type A, female) in the front
panel. The internal USB 2.0 interface is accessible via a 5-pin DUBOX connector located on the
board. Power control and overcurrent protection are ensured for all 6 USB interfaces.
The CDC-device reduces the starting current by sequentially powering up the USB ports.
The CPCI-USB-5 runs with standard USB-Serial system-drivers of the common operating systems.
