Chapter 7: Programming 7-13
Program Parameter Descriptions
Within the Base Programming State are several Specific Programming
Modes. Each of these have specific programming parameters.
Communications Protocol
The Communications Protocol programming mode selects the protocol
that the NCR 7870 Scanner/Scale uses to communicate with the host
terminal.
Note:
The factory sets the Communications Protocol according to the
specifications on your order. Before changing the Communications
Protocol, the NCR 7870 must contain the correct Communications
Interface Board. Also, since there is no default Communications
Protocol, the Default tag does not change this parameter.

Specific Program Parameters
OCIA NCR Short (Datachecker) – Hex 0 tag
NCR short format OCIA is the scanner only (NCR 7870-1000/3000)
protocol used in older NCR terminal systems such as 2557 and 2126
systems. Later model terminals may also use this format for scanner
only configurations. If the scale is enabled (NCR 7870-
2000/4000/4500), a system using the short format OCIA protocol uses
the OCIA Dual-Cable setting as explained under OCIA Dual-Cable.
This format accommodates only 5 data bits per character and supports
only UPC/EAN bar code data.
