Third-Party Peripheral Certification
Third-party peripherals must be certified with the NCR KC5 or a potential ESD
issue can occur. Third-party peripherals include any electrically powered devices
connected to the platform that are not an NCR-branded product or a certified
solution advocated by NCR. Examples of third-party products include PIN pad
devices, printers, external CD-ROM drives, and so forth.
Peripherals tend to be less sensitive to electrostatic damage when directly
grounded through their power cords. If the peripheral is powered by the
terminal and has no dedicated ground, then all of the ESD energy is coupled into
the port connection. Some devices may require the use of an in-line galvanic
isolator/surge protector in order to prevent problems.
The NCR TPP/SCER process is designed to evaluate third party peripherals and
determine whether additional protective devices are needed.
