5-52 Chapter 5: Programming
Scanner/Scale Format
The Scanner or Scanner/Scale Format option permits forcing the data format to either scanner
only format or scanner/scale format to accommodate the host terminal. In some circumstances
a host terminal may not be able to handle the normal format sent to it. In that case, selecting
one of these options permits the use of the other format.
The choices for this option are as follows:
Hex 4 for Scanner only format
Hex 5 for Scanner/Scale format
The normal (default) format for scanner only tag data messages is as follows:
Scanner-Only Tag Data
Message Format
Prefix Byte Label Identifier Tag Data PPD Terminator Byte BCC Byte
16564
Shading indicates optional information.
The normal (default) format for scanner/scale tag data messages is as follows:
Scanner/Scale Tag Data
Message Format
Prefix Byte Label Identifier Tag Data PPD Terminator Byte BCC Byte
30 38
Add FC
16565Shading indicates optional information.
The difference between the scanner only and the scanner/scale format is that the scanner/scale
format has an address and a function code following the optional Prefix Byte. For more
detailed information on message formats refer to the NCR Scanner/Scale Interface
Programmer's Guide (BD20-1074-A).
