If you are using the Encoder, it will automatically put in the start/stop characters for you and allow you to choose the optional check character.Ĭalculation of Code39 Modulo 43 Check Characterįor example if the data "1234" is to be encoded as a barcode. To represent the FULL ASCII, a sequences of two characters(according to Industry Specifications) of Code 39 are used in some of the characters.įor example, to encode the data "123456", you can key in the following in your text editor and choose the Code 39 barcode font.įor example, to encode the data "45346345", you can key in the following in your text editor and choose the Code 39 barcode font. All of them have a simple a direct mapping.Īll characters supported by the Code 39 ASCII barcode are as shown below. It is shown below.Īll characters supported by the barcode are as shown below. The list below illustrates the seven different fonts that is supplied for Code 39.Īdditionally, ConnectCode also provides a font for Code 39 that includes human text. The barcodes name are appended with characters like "S1" or "S2" etc., with each one of them representing a different height. These barcodes with seven different heights are provided in seven fonts with different names. However, as the substitution mechanism is not easy to perform manually, it is recommended to use this barcode through the Software Encoder or the supplied VB macros.ĬonnectCode Code 39 barcode supports up to seven different heights. The Code 39 barcode that employs this mechanism is known as the Code 39 Extended barcode or Code 39 ASCII barcode.ĬonnectCode Code 39 barcode font is able to support this Code 39 ASCII barcode. A modulo 43 check character is available for use if security is required.Īlthough Code 39 only supports 43 characters, it is possible to employ a substitution mechanism based on industry specifications to encode all the 128 ASCII characters. Code 39 is typically not used with a check character and is thus one of the barcodes that you will be able to use easily without an Encoder. This character is also called the start/stop character. If you have a need for using barcodes in your organization and do not want to get into the details, Code 39 is one of the recommended barcodes.Ĭode 39 barcodes begin and end with the '*' character. It supports alphanumeric characters and is used in a wide variety of applications. It is a variable length barcode, which means that you will be able to encode any number of characters in the barcode. Code 39 is one of the earliest and most widely used barcode.
