NCR 7870 - Mode 3 - Normal

7-62 Chapter 7: Programming
Mode 3 – Normal
Mode 3 is the normal operating mode. You can program the scanner to
add PACESETTER
Plus
information to the decoded UPC/EAN data
that is sent to the host terminal. Perform the following procedure to
enable or disable PACESETTER
Plus
information.
1. Scan the Programming Mode tag (must be first tag scanned after
power-up).
2. Scan the Hex 3 tag.
3. Scan the Hex 1 tag.
4. Scan the Hex 3 tag.
5. Scan the Hex 1 tag to disable PACESETTER
Plus
information, or the
Hex 2 tag to enable PACESETTER
Plus
information.
6. Scan the Save and Reset tag.
The PACESETTER
Plus
information describes the label readability
much the same way as described in Mode 2. However, the host
software must be capable of receiving the extra data being sent to it.
With OCIA and RS-232 communications, PACESETTER
Plus
information is sent as trailer information. With IBM communications,
PACESETTER
Plus
information is sent as header information that is
located between the last Status byte and the first tag data byte in the
message. The PACESETTER
Plus
format is defined as the normal
UPC/EAN format with the following added.
OCIA RS-232 IBM

x = High nibble containing character parity depending on
communication format (or 0).
