7 - 8 PL3307 Decoder Integration Guide
Simple Serial Interface Default Parameters
This section describes how to set up the decoder with a SSI host. When using SSI, program the decoder via
bar code menu or SSI hosts commands.
Throughout the programming bar code menus, asterisks (
*
) indicate default values.
Table 7-3 lists the defaults for the SSI host. There are two ways to change the default values:
•
Scan the appropriate bar codes in this guide. These new values replace the standard default values in
memory. To recall the default parameter values, scan the
*Restore Defaults bar code on page 4-5 .
•
Download data through the device’s serial port using SSI. Hexadecimal parameter numbers appear in
this chapter below the parameter title, and options appear in parenthesis beneath the accompanying bar
codes. Refer to the
Simple Serial Interface (SSI) Programmer’s Guide for detailed instructions for
changing parameters using this method.

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.
NOTE See Appendix A, Standard Default Parameters for all user preferences, hosts, symbologies, and
miscellaneous default parameters.
