Decoding Preferences

5 - 3

The parameters in this chapter control bar code decoding characteristics. 

Select the Focus Mode to control the working range of the digital scanner: 

Select Far Focus to optimize the digital scanner to read at its far position. Use this mode when scanning 
large bar codes in order to fit these bar codes in the digital scanner’s field of view.

Select Near Focus to optimize the digital scanner to read at its near position. Use this mode when scanning 
small, high-density bar codes.

Smart Focus toggles the focus position after every frame. This mode is ideal for scanning a combination of 
small and large bar codes. Note that this mode can result in a slight loss of scanning aggressiveness as the 
digital scanner toggles between near and far focus.

The default value for DS3478-DP (DPM) digital scanners is Near Focus.
