3.2. Code 
39 
This is the most popular alpha-numeric bar code symbology. It has a set of 43 characters 
(alphanumeric and a few symbols) and can be used with or without a check digit. 
 
3.2.1. Standard/Full ASCII 
The Code 39 Full ASCII option allows the transmission of the 128 ASCII 
characters. Each ASCII character is a combination of two Code 39 characters. It 
can be very useful specially to transmit control characters (STX, ETX, TAB, EOT…) 
as preambles or postambles in a message (see appendix 6.3, page 58). The Code 
39 Full ASCII Table
 is listed in appendix 6.10, page 70. 
 
 
 
 
3.2.2.  Full ASCII Extended 
In Keyboard-Wedge mode, function keys like F1 to F12, 
t
, HOME, CLEAR… can 
be emulated using this function. 
The function key to be emulated is represented by two Code 39 characters from 
the Code 39 Full ASCII Extended Table (see appendix 6.8, page 65), which can 
be part of the symbol or separate from it. 
 
 
 
 
 
 
 
 
 
 
The function key value to be emulated can be set as a preamble or a postamble of 
message (see appendix 6.3, page 58).
