2.8.3 Triggered Mode
In Triggered mode, the focus position can be set depending on the received external input
(photocell, barrier, serial message…). This mode represents the most traditional Flash™
function, since it requires photocells, barriers or a dedicated interface to the Host (PC or
PLC). The excellent performance of the DS6400 optic platform allows covering an area of
80 x 80 cm containing a 38 mm/15 mils resolution code by using one photocell only.

2.8.4 D-FLASH™ Mode
In D-Flash™ mode, the focus position can be set depending on the measured distance (Dn
in the figure below) between the scanner and the scanned object. This is the most innovative
and flexible function, that makes different software implementations possible. The
D-FLASH™
development has been based on the minimum distance detected. Thus, it can
solve the main part of the applications. Further developments of D-FLASH™ will be provided
according to the specific application needs.
