MATRIX 410™ REFERENCE MANUAL

is the minimum Exposure Time value obtainable for the specific application. It can
be evaluated in static reading conditions and depends on the Matrix reader model selected
for the application (internal lighting system, optical lens, diaphragm aperture, reading
distance) and on any external lighting system. It may also depend on code printing quality,
and reader position.
The Internal Lighting Mode parameter allows setting the operating mode of the internal
lighting system. The possible values are:
Disabled: the built-in LED array is turned off all the time. This option can be useful if using
an external lighting system;
Always ON: the built-in LED array is turned on all the time at the lowest power level. This
option is useful if the LED-array blinking (Strobed operating mode) disturbs the operator.
Very High/High/Medium-Power Strobed: the built-in LED array is on only during the image
exposure time. Three different lighting levels can be set.
NOTE
To avoid LED array overheating, for Power Strobed settings, the program
automatically limits the range of allowed values for the Exposure Time
parameter. Therefore, after changes to Internal Lighting Mode, recheck
Exposure Time.
Continuous High-Power: the internal lighting system is turned on continuously at the
highest power level. This option is useful if the LED array blinking (Strobed lighting mode)
disturbs the operator. For other blinking considerations see the Energy Saving During
Phase OFF parameter in the Help On Line.
CAUTION
To avoid damage to the devices, for LT-010 and LT-011 illuminators you
must correctly associate the illuminator to the Matrix 410™ through the Set
Lighting System Part Number from the VisiSet™ Tools menu. VisiSet™ will
correctly manage the following settings for these illuminators:
High-Power Strobed and Continuous High-Power selections are not
allowed.
Very High-Power Strobed selection does not allow Region Of Interest
windowing.
