Symbologies 13-5

Introduction

This chapter describes symbology features and provides the programming bar codes for selecting these features. Before
programming, follow the instructions in Chapter 1, Getting Started.
The scanner is shipped with the settings shown in the Symbology Parameter Defaults on page 13-6 (also see Appendix A, Standard
Default Parameters for all host device and miscellaneous defaults). If the default values suit requirements, programming is not
necessary.
To set feature values, scan a single bar code or a short bar code sequence. The settings are stored in non-volatile memory and are
preserved even when the scanner is powered down.
If not using a Synapse or USB cable, select a host type (see each host chapter for specific host information) after the power-up beeps
sound. This is only necessary upon the first power-up when connected to a new host.
To return all features to default values, scan the appropriate default bar code on page 5-5. Throughout the programming bar code
*
menus, default values are indicated with asterisks ( ).

Scanning Sequence Examples

In most cases, scanning one bar code sets the parameter value. For example, to transmit bar code data without the UPC-A check digit,
simply scan the Do Not Transmit UPC-A Check Digit bar code under Transmit UPC-A Check Digit on page 13-13. The scanner issues
a fast warble beep and the LED turns green, signifying a successful parameter entry.
Other parameters, such as Set Length(s) for D 2 of 5, require scanning several bar codes. See the individual parameter, such as Set
Length(s) for D 2 of 5, for this procedure.

Errors While Scanning

Unless otherwise specified, to correct an error during a scanning sequence, just re-scan the correct parameter.
