Datalogic Scanning QD 2300 manual Chapter Symbologies, Introduction

Symbologies

Introduction

This chapter describes symbology features and provides the programming bar codes for selecting these features. Before programming, follow the instructions in Chapter 2, Get- ting Started.

The scanner is shipped with the settings shown in Table 23 on page 96 (also see Appen- dix B, Standard Defaults 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 USB cable, select a host type (see each host chapter for specific host infor- mation) 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 21. 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 104. 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.
