The VB34 master reader (as an Ethernet, DeviceNet or Profibus model) is connected
to an external fieldbus host. It can be activated by a signal from the external host or
always be active in automatic operation mode.

As already described, a C-BOX 100 can supply a maximum of 3 readers. If more than
3 readers are used, connect the different groups with a CAB611X cable, which does
not loop in the supply lines, and supply the individual groups separately.

FLASH™ dynamic focusing
An innovation of the VB34 is the linear motor, which can be used to control the reading
position of the scanner via software. This dynamic system with the name Flash™ is
able to assume any reading position from the minimum position to the maximum
position.
The Flash™ function is programmed via the configuration software (see the online
help for details) and has the following operating modes:
• Fixed adjustment
• Continuous adjustment
• Trigger operating mode
• D-Flash™ operating mode
