What to Do After Receiving the V550-A20
There are a few common terms in bar code scanning that you need to
know before you mount your V550-A20. Understanding these terms
will help you when you mount your scanner or if you ever have to
move your scanner from its original mounting place.
Ladder
orientation refers to a bar code whose bars are parallel to the
bar code's direction of travel. Picket Fence means that the bars of the
bar code are perpendicular to the direction of travel. Regardless of
the direction of travel, the scan line
must be perpendicular to the bars.
