Parameters
• RIGHT/BLUE (type-dependent): This lighting type offers the maximum contrast for codes in
the wavelength spectrum between green and red and can improve the reflective properties
of codes on metal surfaces.
• B
OTH/RED + BLUE (type-dependent): The combination of both illumination types offers the
maximum contrast for black codes. The reading area is illuminated uniformly with increased
light output. This setting is recommended for large reading distances and when the back-
ground color is unknown or subject to change.
• B
OTH/INFRARED (type-dependent): The advantage of the infrared lighting is that the light is
invisible to humans, meaning that no disruptive light sources are emitted from the device.
The code contrast achieved by the lighting is dependent on the code's material properties
and surface condition and must be tested.
Individual parameter values are not supported by all device types.
Optimal illumination of the reading field and an increased read rate are achieved by setting
the internal lighting.
5.4.1.4.2 Aiming laser
For various operating statuses, you can use the Aiming laser parameter to mark the opti-
mum position for the codes in the center of the reading area directly on the object using the
integrated laser pointer.
As a result, you can easily position the codes manually and achieve optimum alignment.
• O
FF: Aiming laser is deactivated.
• L
IVE IMAGE, AUTO-SETUP: Aiming laser is only activated to set up the LECTOR
®
620.
• T
RIGGER, LIVE IMAGE, AUTO-SETUP: Aiming laser remains activated as long as the reading gate
is open.
To avoid malfunctions caused by the aiming laser, deactivate it (O
FF). For manual rea-
ding or if the position changes frequently, the T
RIGGER, LIVE IMAGE, AUTO-SETUP setting is re-
commended.
To activate/deactivate the aiming laser using keys on the LECTOR
®
620, the Function
parameter must have value T
RIGGER AND AIMING LASER.
