Third Party Peripheral Certification

Third party peripherals must be certified with the MGC or a potential ESD issue can occur. Third party peripherals include any electrically powered devices connected to the MGC that is not an NCR branded product or a certified solution advocated by NCR. Examples of third party products include printers, external CD-ROM drives, cash drawers, cigarette boxes, pin pad devices, etc.

Peripherals tend to be less sensitive to electrostatic damage when directly grounded through their power cords. If the peripheral is powered by the MGC 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.
