IP Threshold

Threshold Mode
Usage: Fixed Mode works best when decode time must be as short as possible
and the reflectance and illumination of the symbol area is uniform and
unchanging. Cycle Fixed Mode is useful in applications where decode
time can be slightly longer, and reflectance and illumination of the symbol
area is uniform and unchanging. Otherwise, Adaptive Mode is the preferred
mode.
Definition: This value switches the image processing threshold mode between the
Adaptive, Fixed, and Cycle Fixed modes.
An adaptive routine sets the light/dark threshold using data acquired from
the current read. A fixed routine applies the same gray scale threshold
value to each and every symbol. A cycle fixed routine loops through a
pre-defined range of values (Cycle Min to Cycle Max) by pre-defined
increments (Cycle Step).
Serial Cmd: <K512,threshold
Default: Adaptive
Options: 0 = Adaptive
2 = Cycle Fixed
Threshold Value
Usage: A higher value will increase the threshold for distinguishing between light
and dark elements.
Definition: Determines how the Imager will distinguish light pixels from dark pixels.
This value is used for Fixed Mode only. When Adaptive Mode is set,
this value is ignored.
Serial Cmd: <K512,threshold
Default: 128
Options: 0 to 255
Cycle Min
Definition: Starting value of the cycle mode.
Serial Cmd: <K512,threshold mode,threshold
Default: 0
Options: 0 to 255
Important: Cycle Min must be a smaller numerical value than Cycle Max.
