A Media ID generation rule consists of a maximum of six colon-separate fields. Numbers define the positions of the characters in the bar code that are to be extracted. For example, the number 2 in a field extracts the second character (from the left) of the bar code. You can specify numbers in any order.

To insert a specific character in a generated media idea, precede the character by a pound sign (#). Any alphanumeric characters that are specified must be valid for a media ID.

Use rules to create media IDs of many formats. However, it may be difficult to manage media if the label on the media and the generated media ID are different.
