5 - 2 Symbol DS3407 Product Reference Guide
Scanning Sequence Examples
In most cases scanning one bar code sets the parameter value. For example, to disable the decode aiming pattern,
scan the Disable Decode Aiming Pattern bar code listed under Decode Aiming Pattern on page 5-6. The digital
scanner issues a fast warble beep and the LED turns green, signifying a successful parameter entry.
Other parameters require scanning several bar codes. See these parameter descriptions for this procedure.
Errors While Scanning
Unless otherwise specified, to correct an error during a scanning sequence, just re-scan the correct parameter.
Imaging Preferences Parameter Defaults
Table 5-1 lists the defaults for imaging preferences parameters. There are two ways to change the default values:
• Scan the appropriate bar codes in this guide. These new values replace the standard default values in
memory. To recall the default parameter values, scan the *Restore Defaults bar code on page 4-4.
• Download data through the device’s serial port using SSI. Hexadecimal parameter numbers appear in this
chapter below the parameter title, and options appear in parenthesis beneath the accompanying bar codes.
Refer to the Simple Serial Interface (SSI) Programmer’s Guide for detailed instructions for changing
parameters using this method.
NOTE See Appendix A, Standard Default Parameters for all user preferences, hosts, symbologies, and
miscellaneous default parameters.
