6.8 Using Bar Code Reader for Product Qualification
Vision includes a method to use a bar code reader and read coded sample name directly from the
container label without operating keyboard or mouse. The bar code reader has to be of the “wedge”
type, plugged between keyboard and the computer. It has to be programmable, i.e., it has to be able
to automatically send preamble and postamble (string of ASCII characters added before and after the
scanned bar code) information to Vision.
To use this option:
Program the bar code reader so that preamble is made of one horizontal tab (ASCII symbol
HT, decimal code 009) and the postamble is made of two tabs and an enter (ASCII symbol CR,
decimal code 013. Please note that the bar code reader may insert Enter after each
transmission by itself. If you want to see and check what you did, open Word and scan any
bar code. If you click on Show/Hide icon (kind of funny double letter P with the belly
backwards) you will see the symbols o the screen.
Create an Operations Method. Configure the method in a standard way and click on Timer. In
