Appendix F
Using the optional expansion modules
Follow the instructions in this appendix to use the
PTC-2124’s optional laser scanner module.
Using the laser scanner module
If your PTC-2124 has an attached laser scanner
module, the unit can be programmed to recognize,
read, and discriminate automatically among six 1D
bar-code types. See the next page for a list of these
bar-code types and the information provided by your
organization for details on how your PTC has been
programmed.
$
Do not stare into the PTC’s
laser beam or point the
scanner at anyone’s eyes.
Permanent eye damage could
result. Follow this procedure to scan bar-code labels with a
laser scanner module.
1. Point the PTC at the label to be scanned.
See the information provided by
your organization for the
recommended scanning distance. The maximum distance from the scanner lens to
the label depends on the size of the label being
scanned and the type of laser that was selected by
your organization.
Your application program may not
support scanned data for all fields.
Consult the documentation for your
application to determine when the
scanner and scan triggers are
enabled. 2. Press one of the PTC’s scan triggers to start
scanning.
3. Watch the line of light made by the scanner as it
scans the bar code.
4. If the scan is successful, the CPU LED glows solid
green and the PTC beeps.
5. Hold the PTC at an angle to the bar code so that
the scanning line is perpendicular to the bars in
the bar-code label. Make sure the line passes over
all of the bars.
