Suggestions

target barcode (always
returns No Read) or the
Auto Setup procedure
Fails.
Check synchronization of reading pulse with object to read:
Is the scan line correctly positioned?
Place barcode in the center of scan line and run Test mode
(selectable by Genius™ as an Operating Mode). If you still have
trouble, check the following:
Is the reading distance within that allowed (see reading
diagrams)?
Is the Tilt angle too large?
Is the Skew angle less than 10° (direct reflection)?
Choose the Code Definition branch and enable different
Code Symbologies (except Pharmacode). Length = Min
and Max (variable).
Is the Bar Code quality sufficient?
If you had no success, try to perform the test using the
BARCODE TEST CHART included with the product.

Is the serial cable connected?
Is the correct wiring respected?
Are serial host settings equivalent to the serial device

If using CBX, be sure the RS485 termination switch is
positioned to OFF.

corrupted or incomplete
In the Genius™ program select the Data Communication
Settings/Data Format/Standard Parameters branch and
check the Header, Separators, and Terminator values
Also check the Code Field Length and Fill Character values.
Are the COM port parameters correctly assigned?

Reader Failure
Character (<BEL> char

Contact your local Datalogic office or Datalogic Partner or
ARC, because either a Motor or Laser failure has occurred.
Note the exact model and Serial Number of the device.
How do I obtain my
units’ serial
numbers?
The device’s serial number is printed on a label that is affixed
to the body of the reader.
Serial numbers consist of 9 characters: one letter, 2
