Equipment Grounding Requirements
When connecting cables from other AC-powered equipment (such as computer terminals) to
the Interface card, make sure the other equipment is properly grounded. Ground
connections are normally provided by the ground (third) prong of an AC plug. Some PCs,
especially portables and laptops, have power supplies with two-pronged plugs; they are not
properly grounded.
When a cable is run from a PC that is not properly grounded to the Interface port of the
system, a high voltage differential (up to 100 VAC) may result between the system and
the PC. This can severely damage the Interface card, PC, or both.
