Reading:
Target code cannot be read (no result
is ever output)
• Check the synchronization between the
read impulse and the object to be read.
• Is the scan line aligned correctly?·Place
a barcode in the center of the scan line
and start the test mode (can be selected
as the operating mode in Genius™). If
the problem persists:
• Does the reading distance lie in the
permissible limits (see reading fields)?
• Is the tilt angle too large?
• Is the angle of rotation under 10° (di-
rect reflection)?
• Select the CODE properties tab and
activate various code types (except for
pharmacode).
Length = variable.
• Is the code quality sufficient?
• If the problem persists, carry out a test
with the test sheet from Datalogic, en-
closed with the product.
Communication:
The device does not transmit any data
to the host.
• Is the cable for the serial interface con-
nected?
• Is the wiring correct?
• If using the primary RS232 or RS485 in-
terface, is the earth reference connected
with the correct signal ground SGND (al-
so referred to as GND_ISO)? Bear in
mind that this ground does not have any
connection to the ground of the supply
(GND).
• If using a C-BOX 100, make sure that the
RS485 termination switch is set to OFF.
• Are the serial communication parame-
ters set in the same way for the host and
the device?
Communication:
No data appears on the terminal.
• In the configuration software, activate
parameter "Transmitted data" in the data
communication settings for the primary/
secondary interface.
