paragraph 4 of getting started in the manual:

You must program the 3400 to work with your terminal
or computer by scanning the appropriate programming
bar code(s). (For further instructions, see Chapter 2,
section 2.2 or 2.3.)

Have you done that. Do you have the manual?

om...
Hi,
I am using a Welch Allyn 3400 barcode reader, DECODED, and I hooked it up
to my
keyboard. All I want to do for now is "see" the barcode I just scanned
in Word or Excel.

I don't see it... Why ? I double checked that the cable is correctly
attached to my scanner and the keyboard port (not the mouse port). I
reset the manufactured settings (default). I hear a beep when I scan a
barcode, but I can't see it.

Any help is much appreciated !

Thanks!
