Work can become more efficient by allocating a convenient function to the Magic Key.

Modes

  • Data re-transfer mode - Previously sent data is re-transferred every time the Magic Key is pressed.
  • Designated character transfer mode - Predetermined characters are sent every time the Magic Key is pressed.
  • Read code switching mode - Two predetermined read codes are alternated every time the Magic Key is pressed.

Configuration software

index4-2__300x144

Free software applications “Scanner Setting” are included, allowing easy configuration of the reading condition, data format, etc. according to the object to be read.
These applications providing convenient functions can reduce customers’ work load concerning application development.

Image capture

index4-3__300x144

Image shooting possible
When a non-conforming product is detected on a plant production line, for example, the image of the product can be captured with GT20 on site and sent to its host.
