CODE 39: Check Digit: OFF <>
For applications requiring enhanced data security, a Modulo 43 check digit can be used on CODE 39 and Full ASCII CODE 39
bar codes. When used, the check digit immediately follows the last data character. Use this option to enable or disable the
check digit requirement for CODE 39 bar codes. When the decoder decodes a CODE 39 bar code it will calculate the Modulo
43 check digit and verify it against the decoded data.
CODE 39: Send Check Digit: OFF
<> 
Some applications may require that you use a check digit in the bar code for security but do not require the check digit be
transmitted to the computer. Use this option to have the decoder either send the check digit to the computer or remove the
check digit from the transmitted data.
CODE 39: Append Mode: OFF
<>
It is sometimes advantageous to break up long messages into multiple, shorter symbols. If the first data character of a CODE
39 bar code is a SPACE, the decoder may be programmed to append the data following the space to a concatenation buffer.
Each time a CODE 39 bar code with a leading space is read, the decoder will sound two short beeps to indicated it has
appended the bar code to the concatenation buffer. This operation continues for all successive CODE 39 bar codes with a
leading SPACE. When a CODE 39 bar code is read which does not contain a leading SPACE, the contents are appended to
the buffer, the entire buffer is transmitted, and the buffer is cleared. Use this option to enable the message append mode of the
decoder.
Note: If you scan a bar code from a different symbology the data in the concatenation buffer will be discarded and the bar
code just read will be output.
Note: If you scan a bar code that begins with a - (dash), the concatenation buffer will be cleared and no data will be output.
CODE 39: Secondary Start/Stop Char: NONE
<>
Standard CODE 39 uses the * character as its primary start/stop characters. If you are attempting to read CODE 39 bar codes
that use another type of Start/Stop character, use this option to specify the character. The default for this option is NONE, which
allows the CODE 39 decoder to only read the standard CODE 39 bar codes. You may choose between $, %, /, and + as
secondary Start/Stop characters.
CODE 39: Send Start/Stop Chars: OFF
<> 
Use this option to configure the decoder to transmit the CODE 39 Start/Stop characters to the computer. The default for this
option is OFF, to not transmit Start/Stop characters.
CODE 39: Maximum Length: 49
<> 
CODE 39: Minimum Length: 0 <> 
Use these options to configure the minimum and maximum lengths of CODE 39 bar codes that can be read. If you configure
the Maximum Length to 10 characters and the Minimum Length to 5 characters, the decoder will not read CODE 39 bar codes
with less than 5 characters and more than 10 characters. When calculating length requirements, do not include any Start/Stop
characters.
<>
CODE 39: Type ID: a DEC 97 HEX 61 ASCII ALT 
Use this option to configure the Type ID for the CODE 39 bar code. If the Full ASCII option is enabled then this Type ID is used
as the Type ID for Full ASCII CODE 39 bar codes. Sometime it may be necessary to transmit a Type ID for the type of the bar
code that was just read, this will allow a system to determine what to do with the data for the bar code. For example, CODE 39
bar codes could be used for employee identification purposes and UPC bar codes could be used for product codes. The Type
ID for CODE 39 and UPC bar codes would be different allowing the system to automatically use the information in the
appropriate modules. Type ID's can be transmitted as a prefix or a suffix to the bar code data, for more information see
OTHER: Send Bar Code Type ID on page 18.
CODE 39: Control Character Override: OFF
<>
Use this option to disable all Edits, Macros, Strings, and the Type ID for CODE 39 bar codes that contain control characters.
When this option is enabled and a CODE 39 containing control characters is read, the special key macros are applied, and the
data is transmitted to the computer. With this option enabled, you can use bar codes with special control characters to control
the computer system without going through the standard editing procedures.
