connector on the terminal.

(Com 1)
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.
