2. The CLX is not transferring any reading
results to the host
•
Reading pulse is not functioning
correctly.
•
Wiring fault in data connection.
•
Voltage level incorrect.
•
Host interface in CLX parameterized
incorrectly.
•

for the separator; this is disabled by de-
fault)
The CLX has diagnosed a device error in the
self-test
Switch the CLX off and on again. Does the
"Device Ready" LED light up? If not, contact
the SICK Service department.
4. The data content of the bar code output
by the CLX is incorrect or incomplete
•
The data format on the host interface is
parameterized incorrectly in the CLX
•
The CLX suppresses the last character in
the bar code
•
In the "CLV-Setup" program: choose the
