Third Party Peripheral Certification
Third party peripherals must be certified with the POS terminal or a potential ESD issue
can occur. Third party peripherals include any electrically powered devices connected
to the POS terminal 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 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.
LAN Communications
The NCR 7601 Terminal supports Ethernet 10/100/1000baseT Local Area Network (LAN)
communication protocol. For Ethernet communications wiring specifications, refer to
the
NCR Ethernet Communication Wiring Guide (BST0-2118-82).
