Chapter 5 Imager Preferences
Introduction
This chapter describes imager preference features and provides the programming bar codes for selecting these
features.
The decoder ships with the settings shown in the Imager Preferences Default Table on page 5-2 (also see
Appendix A, Standard Default Parameters for all host 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 appear in this chapter below the parameter title, and options appear 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 beep signal activates.
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 4-4 . 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 you can see the bar code clearly, and
bars and/or spaces are not merging.
