Operation and communication
Number of decoded codes
Normally, the camera detects five codes at a nominal distance of 100 mm. Only one code is
required to calculate the position. If there is a constant strong fluctuation of the number of
codes read, this can be indicative of individual codes that are dirty or damaged, or an inconsis-
tent measuring distance.
