Malfunction
6. Reading mode:
(Dev. Rdy LED lit)
Output of bar code content
incorrect or incomplete.
7.
Reading mode:
(Dev. Rdy LED lit)
Read ok, however, the CLV
does not output the
reading result until after
the end of the reading
pulse in Immediate output
mode.
8. Reading mode:
The scan line is not visible
during the reading pulse.
The Dev. Rdy LED
extinguishes
9. Reading mode:
(Dev. Rdy LED Lit)
The Result 1..3 switching
outputs do not supply a
pulse.
10. CLV responses are
not acknowledged by
beeper.
Possible cause
1. 2/5 Interleaved: CLV suppresses
the first character of the code in
the data output string
2. CLV suppresses the last character
of the code in the data output
string
3. CLV outputs non-definable
characters
4. The control characters contained
in the code, header, separator or
terminator appear as @ in the
data output string
(possible with Code 39, Code
128, Code 93 and EAN 128)
1. The min. number of bar codes to
be read is higher than the actual
number that occur in the reading
pulse
2. Evaluation criteria (C
ODE
C
ONFIGURATION
) for bar code types
are incorrect
-
Reading interval terminated
incorrectly: the internal monitoring
function has deactivated the laser
diode after 10 min. (default)
1. The result for the assigned result
display function does not occur in
the reading process
2. Outputs switching incorrectly
-
Beeper deactivated (beeper
volume: OFF)
Check
1. Does the CLV suppress the
leading zero?
2. Output of the last character is
disabled for this code type
3. Data format set incorrectly
4a.CLV replaces each control
character in the protocol
frame with @. Because control
characters are transferred in
code: Hex-ASCII output
activated?
4b.Are characters outside the
code referred to in the format
mask?
