CHAPTER 9 SYMBOLOGIES
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 decoder is shipped with the settings shown in Table 9-1 on page 9-2 (also see Appendix A, Standard
Default Parameters for all host device and miscellaneous defaults). If the default values suit requirements,
programming is not necessary.
There are two ways to change a parameter value:
•
Scan the appropriate bar codes in this guide. These new values replace the standard default values in
memory.
•
For SSI and USB SNAPI hosts, send a “parameter send” command from the host system. Hexadecimal
parameter numbers are shown in this chapter below the parameter title, and options are shown in
parenthesis beneath the accompanying bar codes. See the
Simple Serial Interface (SSI) Programmer’s
Guide for detailed instructions for changing parameter values using this method.
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 Set Default Parameter on page 4-5 . Throughout the
programming bar code menus, asterisks (
*
) indicate default values.
NOTE Most computer monitors allow scanning the bar codes directly on the screen. When scanning from the
screen, be sure to set the document magnification to a level where the bar code can be seen clearly, and
bars and/or spaces are not merging.
