PECIFICATION

This appendix provides specifications for creating bar code labels used on cartridges in Plasmon AIT

libraries. The specifications are defined to both standardize the label and allow users the option of

purchasing or printing their own labels.

Overview

The AIT cartridge label uses the bar code symbology of USS-39. A description and definition of

this symbology is available from the Automatic Identification Manufacturers (AIM) specification

Uniform Symbol Specification (USS-39) and the ANSI MH10.8M-1993 ANSI Barcode

specification.

Bar Code Characters

Print the bar code in accordance with the latest revision of the ANSI MH10.8M specification (Code 3-of-9).

The bar code can have between seven and nine characters as shown in the following table.

Checksum Character

NOTE

The checksum character is mandatory to these labels.

The checksum character is computed as the character corresponding to the modulus 43 sum of all the

values in the eight character section of the bar code. Character values are derived from the following table.

4 to 6 alphanumeric characters, which you select

from the following table.
