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.
