Symbologies 8-5

Introduction

This chapter describes all symbology features and provides the programming bar codes
necessary for selecting these features for the scanner. Before programming, follow the
instructions in Chapter 1, Getting Started.
The scanner is shipped with the settings shown in the Symbology Default Table on page 8-
6 (also see Chapter A, Standard Default Parameters for all host device and miscellaneous
scanner defaults). If the default values suit the requirements, programming may not be
necessary. Features values are set by scanning single bar codes or short bar code sequences.
To return all features to their default values, scan the Set All Defaults bar code on page 4-5.
If the USB cable is not being used, a host type must be selected. See each host chapter for
specific host information.

Scanning Sequence Examples

In most cases, only one bar code needs to be scanned to set a specific parameter value. For
example, to transmit bar code data without the UPC-A check digit, scan the
Do Not Transmit
bar code listed under Transmit UPC-A/UPC-E/UPC-E1 Check Digit on
UPC-A Check Digit
page 8-15. 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 that several bar codes be
scanned in the proper sequence. See the individual parameter, like Set Length(s) for D 2
of 5, for this procedure.

Errors While Scanning

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