VP6800 Grounding Requirements
The VP6800 is designed such that it is isolated from the signal noise of other devices and does not
require additional grounding. However, to add your own grounding cable, follow the diagrams
provided in the
section above. Note that the Shield GND and GND are separate from the cable.
Note:
The metal plate on the back of the card swipe area of the VP6800 is not designed for
grounding; this plate is used only to prevent wear of the plastic housing during card swipes.
