Chapter 5: Programming  5-29 
Tone Frequency 
This parameter permits you to set the frequency of the Code 39 tone. Set this parameter by 
scanning the appropriate Hex tag (Hex 0 to Hex 7). 
Hex Tag  Frequency in Hertz 
Hex 0  3348 Hz 
Hex 1  2976 Hz 
Hex 2  2679 Hz 
Hex 3  2435 Hz 
Hex 4  2232 Hz 
Hex 5  3906 Hz 
Hex 6  3750 Hz 
Hex 7  3538 Hz 
Note:  The default Code 39 tone frequency is 2232 Hertz (Hex 4). 
Code 39 Halves Enable 
This parameter attempts to build a Code 39 tag on the three longest tag lengths seen (tag 
lengths are saved in C39_Max_Scanned1, C39_Max_Scanned2, and C39_Max_Scanned3) as 
well as on  any Code 39 tag length that contains a Code 39 check digit. 
Code 39 Halves Enabled programming requires a half tag partial longer than one-half of the 
longest Code 39 tag ever seen by a scanner in order to prevent getting a short tag from a longer 
one. 
Code 39 Stitch Enable 
This parameter attempts to stitch a tag to the longest tag scanned by a full strike across the 
whole tag. This parameter includes the Stitching Code 39 Check Digit (C39_Stitch_CD_tags) 
option. 
Code 39 Stitch Check Digit 
This parameter permits tag lengths containing a Code 39 Check Digit to be stitched if Code 39 
Stitch Enable is active. 
Check Digit Length1 and Length2 
These Check Digit lengths are programmed to permit specific length of Code 39 tag to require 
a Code 39 Check Digit. These can be any length in the range of 01-36 and are not required to 
be in the range of C39 Minimum Length and C39 Maximum Length programming.
