Dual serial port data acquisition interface assembly for a data storage device

摘要

A dual serial port data acquisition interface assembly including a printed circuit board for supporting additional components of the dual serial port assembly, a personal computer peripheral component interconnect connector secured to the printed circuit board for passing data between the printed circuit board and a personal computer. A first serial port connector mounted on the printed circuit transferring communication data and synchronization data between the personal computer and the data storage device through a programmed universal asynchronous receiver/transmitter microchip, and a second serial port connector mounted on the printed circuit board passing a performance data of the servo control circuit from the data storage device through a serial-to-parallel converter to the personal computer.
