Barcodeleser ansteuern

Hi,

(Sorry, I can read German but not write it very well)

The best thing to do is to use a keyboard wedge scanner. This is a scanner
you put between the keyboard and the computer. So your applications do not
know about the scanner, it looks like a user is typing the data.

kbd -----> scanner ----->computer

About the barcode components, there are a lot of sites like the delphi super
page you will find components. I myself prefer a simple barcode printer.

Regards
Albert Drent

Yes, and the scanner I am using is programmable to send either
a (programmaable) prefix or postfix character to the actual
scanned code. In this way the program can automatically determine
whether the input comes from the scanner or the keyboard.

It is a keyboard wedge scanner. The Name is UFO Scan Model UF-101,
manufactured in Taiwan (what is not?).
I don't think that this is really of any help to you. The box nor the
manual give any further indication about the manufacturer.
The scanner has a row of LED's and to read the barcode you point
the led row against the barcode and press the trigger.
The scanner is fully programmable including what barcoding used.
There are a total of 9 code including the ones you mention.
In fact, the manual consists purely of a list of barcodes which
are then used to prgram the scanner.
All sounds very vague, I know, but I think it is just an ordinary
scanner, nothing special at all.
