Bi-Optic Scanning
The NCR 7870 combines horizontal and vertical scan patterns. Having
two active scan windows allows the checker to bring a product into the
scan zone without having to orient it to a single scan window. Portions
of the bar code are read by each scanner, assembled into a complete
code by the digital board and sent to the host terminal.
Decode Features
Standard Decode and PACESETTER
Plus
are available for bar code
label decoding. Standard Decode is the standard feature and
PACESETTER
Plus
is the upgrade. Please note that the PACESETTER
Plus
upgrade includes the Standard Decode.
PACESETTER
Plus
Bar code labels in a retail environment are occasionally unreadable.
Labels can be overprinted, underprinted, or truncated. Others may
have missing margins or be placed around corners. PACESETTER
Plus
determines what is wrong with a label, compensates and fixes the data,
and transfers the information to the host terminal. Voice messages can
be used to describe what is wrong with a label.
There are three modes of operation in PACESETTER

.
•
Mode 1 – Inquiry Mode
