4 - 2 Symbol DS9808-R Product Reference Guide Supplement
Simple Serial Interface Default Parameters
Table 4-1 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
Set Default parameter in the Symbol DS9808
Product Reference Guide.
• 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.
See the Simple Serial Interface (SSI) Programmer’s Guide for detailed instructions for changing parameters
using this method.

NOTE SSI interprets Prefix, Suffix1, and Suffix2 values listed in the default table in the Symbol DS9808 Product
Reference Guide differently than other interfaces. SSI does not recognize key categories, only the 3-digit
decimal value. The default value of 7013 is interpreted as CR only.
