Orientation of fields of the SIMATIC RF382R Scanmode
For many applications it may be best to operate the reader so that the tags move from left to
right (or from right to left) at a certain distance in front of the narrow edge of the reader. With
this direction of movement, the horizontal reader field is used, see figure below.
You also have the option of moving the tags up and down (or down and up) past the narrow
edge of the reader. With this direction of movement, uses the vertical reader field is used.
