Quiet zone before and
Quiet zone: To successfully read a bar code label, the laser beam in the scan module
must see all the bars in a label and a clean, non-printed space, or "quiet zone," at each
end of the label.
You will have the best success if you hold the terminal so that the
horizontal reading angle is near zero and the vertical reading angle is near
20 degrees. To get the best scan angle, hold the terminal so that the
scanner is pointing toward the bar code label. Tilt the terminal up or down
slightly (20 degrees). Optimum scan angles vary with the type and print
quality of the bar code label, the distance of the scanner from the label,
and the lighting in the area.
Do not scan the bar code label "straight on." In a 2-degree conical "dead
zone" directly above the label, the laser beam may reflect back into the
scanner window and prevent the terminal from reading the label. At
certain angles and straight on, you may not see the laser beam.
You connect an input device (such as a wand scanner) to the serial port.
You can either use the special cable for the input device or you can use a
standard cable with special adapter cables (P/N 069591 or P/N 069589).
For an updated list of available input devices, contact your local Intermec
representative.
Once you have connected the input device to the terminal, you may need
to configure the Scanner Selection command to optimize the scanning
performance. For help, see "Scanner Selection" in Chapter 6 of the 2400
Family system manual.
After you connect an input device to the 241X, you can modify the
following scanner command options to meet your needs:
• Decode Security
• Scan Ahead
• Scanner Mode
