Installing EMI Filters on Interface Cable Ports

Minimizing the GND’s noise level is important in the interface cable connection. The PCB’s GND and metal case are screwed together to form a low-impedance connection at high frequency.

EMI filters are installed in the interface cable connection. Note that the CD-ROM drive may not operate on some computers if large-capacitance or large-inductance EMI filters are used.
