Reading:

Not possible to 
read the target 
barcode (always 
returns No 
Read) 

• "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 VisoSetup 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 tab and enable different code types 
(except Pharmacode). LENGTH = 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.

Communica-
tion:

Device is not 
transmitting 
anything to the 
host

• "Is the serial cable connected?

• "Is the correct wiring respected?

• "Are serial host settings equivalent to the serial device 
setting?

• "If using C-BOX 100, be sure the RS485 termination 
switch is positioned to OFF.

Communica-
tion:

Data trans-
ferred to the 
host are incor-
rect, corrupted 
or incomplete

• "In the VisoSetup program select the DATA FORMAT 
tab and check for values of HEADER, TERMINATOR, 
SEPARATOR, FILL CHARACTERS

• "Also check the CODE FIELD LENGTH value

• "Are the COM port parameters correctly assigned?

Communica-
tion:

Always returns 
the Reader Fail-
ure Character 
(<BEL>char as 
default)

• "Contact your local Fuchs distributor , 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 
numbers, and another letter followed by 5 numbers.
