9 I/F identification . According to the
voltage level at I/F, the scanner will
automatically select a communication
Interface, when the interface selection of
scanner being set at auto-detection
mode.
The followings list the interface
selection corresponding to the various
voltage level at I/F.
I/F floating-NC: Identified as RS232
I/F short to GND: Identified as
Keyboard wedge. Wire I/F with a
4.7K then ground : Identified as USB Wire I/F with a 4.7K then ground
