Barcode Scanner - The cursor jumps a row in a Microsoft Excel worksheet.

Hello.
I hope I'm in the correct section (I've posted here because I've seen this http://www.excelforum.com/excel-prog...e-scanner.html ).

I have at my job 2 barcode scanners and I try to use them in order to import some data in to a Microsoft Excel worksheet.
One of the scanners works the way I want: after the barcode is scanned it inputs the data in the right column (column D in my case) from the excel worksheet and the cursor goes down a row on the same column.
The other barcode scanner does almost the same thing except that after it inputs the data in to the table the cursor goes down 2 rows on the same column.

Can someone tell me how to fix this problem?
Thank you in advance for your time.

Here's the manual: http://www.honeywellaidc.com/Catalog...%20Rev%20C.pdf. You can change the characters that it appends to the scan.
