Chapter Two -- Rockey4ND Basic Theory
Rockey4ND Internal Structure At the core of Rockey4ND is a specialized CPU with a USB interface. It supports the USB 1.0 standard and is compatible with USB 2.0 standard. In addition to the CPU is a non-volatile memory chip that can save your data in the event of a power loss. The Rockey4ND functions are divided into User, Module and Algorithm zones. The developer may store important information (such as an application serial number) inside the dongle. You can write to the Rockey4ND dongle as many as 100,000 times – there is no appreciable limit on the numbers of reads. The RockeyND chip supports special functions for random number generation, seed code generation and user defined algorithm interpretation. Rockey4ND Hardware Interface Rockey4ND USB supports USB Standard 1.0. At the most 16 USB dongles can attach to a computer with a USB extension HUB. The LED of Rockey4ND USB indicates the status of the dongle. (In a normal state after the dongle is attached to the computer the LED will be on all the time. If the LED blinks it indicates that the driver is not installed. Other LED responses indicate hardware failure.). Rockey4ND Installation Problems Rockey4ND is a plug and play USB device. To unplug a Rockey4ND while writing/reading, the dongle may cause crashes to the operating system in some instances.
