Programming Your 7890 Scanner
Communications Protocol

5-8

User’s Guide

Communications Protocol

The Communications Protocol Programming mode
selects the protocol that the 7890 Scanner uses to
communicate with the host terminal or PC. Refer to the
Communications Protocol worksheet in Appendix A.

The Protocol parameter contains seven selections:

•

OCIA NCR Short (0)

•

OCIA NCR Long (1)

•

OCIA Non-NCR (2)

•

IBM 468x Select Address 4A (3)

•

IBM 468x Select Address 4B for 1520BCR (4)

•

RS-232 (5)

•

IBM 468X Select Address 4B for HHBCR (6).

The default protocol is OCIA NCR Short.

OCIA NCR Short (the default protocol) and

OCIA Non-NCR only support UPC and EAN tags.

All requirements for all the protocols except RS-232 and
OCIA long are set in the firmware and cannot be
changed. However, you can program many options for
the RS-232 protocol. These are identified on other
Programming Worksheets.
