Profibus Interface
The Profibus interface is used for communication with an Host and allows expanding the
networking and remote diagnostic capabilities of the scanner.
For further details refer to the “Profibus_Fam6k.pdf” document provided as supplementary
documentation.
2.3.6 Power
Supply
Vdc models:
The supply voltage for correct operation of the scanner must be between 20 and 30 VDC.
The max. power consumption is 35 W including startup current.
Several accessory power supplies are available to power the DX8200A VDC models and
reading station components. See par. 1.5.
A security system allows the laser to activate only once the motor has reached the correct
rotational speed; consequently, the laser beam is generated after a slight delay from the
power on of the scanner.
