VRf: Integrating a bar code reader

Question asked by ramarquardt on Nov 25, 1997

We do this all the time.

You can do this using a simple serial port connected bar code reader.
Just read the serial port.

You can also do it via a keyboard wedge in which case the input goes right
into a normal keyboard input function.

We make both types, see, under the Allen-Bradley label;
and use them in our own test equipment.
Bar code scanners in particular can be seen at

Subject:  Integrating a bar code reader

Has anyone integrated a bar code reader into their system?
I am considering implementing one and I am curious if there is someone out
there who has gone through the implementation.
