4 NCR SelfServ™ XK22 (2246) Site Preparation Guide
Third Party Peripheral Certification
Third party peripherals must be certified with the NCR SelfServ™ XK22 (2246) Kiosk or
a potential ESD issue can occur. Third party peripherals include any electrically
powered devices connected to the kiosk 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.
The NCR Workstation and Peripherals AC Wiring Guide (BST0–2115–53) contains additional
information on this subject.
