Datalogic Scanning HD Manual De Usuario

You can isolate problems with your scanning system by performing 
these checks (refer to Figure 9):

1.

If your scanner’s cable is designed to receive Power Off the 
Terminal (P.O.T.), it will not operate unless it is connected to a 
working host terminal that is powered on.

2.

Ensure that the interface cable is securely attached to the 
host.  Consult your technical support manager or refer to 
your host system manual to identify the proper connection 
for the scanner.

3.

If an external power supply is used, verify that it is securely 
connected to the interface cable and AC outlet. Also ensure 
that the power supply is the correct voltage rating for your 
area.

4.

Check to see that the interface cable is securely connected at 
the scanner handle. Push the connector in to assure that it is 
firmly seated. Use a Phillips head screwdriver to ensure that 
the screw at the bottom of the scanner is fully tightened (but 
do not overtighten).

5.

If, after checking all connections, the scanner still fails to 
function properly, exchange the power supply with a known 
good power supply.

6.

Ensure that the scanner's interface type is compatible with 
the host terminal by consulting your POS system manual 
and/or the PowerScan Scanner Programming Guide.

7.

Verify that the bar codes you are scanning are of satisfactory 
quality.  Bar code label verifiers are available from your 
dealer if you need precise reporting of bar code details.  Bar 
codes that are damaged (wrinkled, smudged, or torn) may 
cause the scanner to read poorly or not at all.  If bar code 
quality seems to be the problem, check to see if the scanner 
will read a known good bar code (see Figure 7). You may also
