Note: The parallel connector on the 7454 terminal is used for the
Customer Display. If the terminal is equipped with a Customer
Display you must temporarily disconnect the display cable. If the
terminal is not equipped with a Customer Display then it is likely
that the terminal does not have a parallel connector and you will
have to install the POS Connector Board.
See the NCR 7454 Retail Terminal Hardware Service Guide
(B005-0000-1342) for information how to open the terminal and
install the POS Connector Board.
