XRF410N™ INSTALLATION

In the
Reading Phase
step, set Acquisition Trigger Type to
Periodic
. The period to set
depends on the application speed, the maximum code length, and the maximum pack height.
To guarantee application functioning, two successive acquisitions must have an overlapping
area in the direction of movement at least equal to the maximum code length.

Note 1
: Decoding Timeout
The Decoding Timeout default values are set based on a statistical analysis of decoding
times measured on a variety of packs considered typical in various T&L applications.
Decoding Timeout depends heavily on the type of acquired images. As a general rule it is
suggested to set a value about equal to three times the Acquisition Period.
In case an application has difficulty decoding with the default values, it is possible to adapt
the timeout setting, particularly for applications where the objects are homogenous.
For example in the case of very “noisy” objects (i.e. writing, repetitive patterns or reflections
present in the area of the code) it is suggested to limit the Decoding Timeout value to two
times the Acquisition Period, and possibly increase the frame rate to have some image
redundancy.
Note 2
: Delay on internal Trigger
In case of multiple XRF410Ns installed next to each other, it is necessary to set an
Acquisition Trigger Delay between adjacent readers to avoid overexposure due to
simultaneous illumination in the FOV.
In these conditions, for a TOP application it is suggested to set a 2 ms delay for all odd
readers in the network while leaving the Master and all even Slaves without a delay (0 ms).
In TOP-SIDE installations it is left to the installer to set the correct delay to avoid
simultaneous illumination in the FOV from more than one reader.
