Determines how the NCR 7800 communicates with the host
terminal or PC.
•
RS-232 Direct (0)
•
RS-232 Indirect (1) - Default
In the Direct Mode of operation, all data sent to the NCR
7800 is displayed. However, in Price Verifiers with firmware
versions of 497-040 and higher, commands to the scanner are
not sent.
In the Indirect Mode of operation, logical addresses are used
to communicate with the NCR 7800. Data to be displayed
must be addressed to the display.
In either mode, the host can reconfigure the NCR 7800 and
change the information to be displayed.
