UID policy

The Department of Defense defines the UID number as:

•The set of data for tangible assets that is globally unique

and unambiguous, ensures data integrity and data quality

throughout life, and supports multi-faced business

applications and users.

Microscan Training Materials ©Microscan Systems, Inc. All rights reserved.

The UID applies to:

•Items >/= $5,000

•Items < $5,000 as directed by requiring activity

•Subassemblies, components and embedded items

•Commonly accepted commercial marks

Sample UID:

•Symbol contrast – lets the user know if contrast settings are

less than acceptable.

UID number format

Example of UID number constructed by an imager:

Encoded Data:

[)>{RS}DD{GS}CAG987654{GS}SERMKLJHUIYD{RS}{EOT}

Constructed UID Number:

D987654MKLJHUIYD

Eliminates the need for custom programming.

UID mode features

•The MS-Q’s UID mode provides the following features:

UID-Only Enabled

UID-Only Enabled with

Error Messaging

UID Enabled with

Pass Through

UID Enabled with

Error Messaging

and Pass

Through

Allows the MS-Q to read UID data strings encoded on ECC 200 Data Matrix symbol and to send

the UID numbers to the hose computer. The imager will not read any other symbol data when UID

is enabled.

Allows the MS-Q to recognize and decode only UID symbols. In addition, the

imager will send an error message to the host if the UID format is incorrect.

Allows both UID-encoded symbols and non-UID

symbols to be decoded and sent to the host.

Allows the MS-Q to decode UID symbols and non-UID

symbols, and to provide error messages if UID format is

incorrect.

UID format verification

•The MS-Q provides suppliers with UID format verification

•Software enables the DoD supplier to scan their UID symbols and

verify that the information is in the correct format:

•If the format is incorrect, the MS-Q will generate an error

message, stating the symbol is a bad UID symbol and the

reason why it violated the specification.

•Error Messaging covers the following:

– Invalid preamble

– Invalid format

– Invalid AI

– Invalid DI

– Invalid TEI

– Spaces

– Lower case characters

– Invalid characters

– UID too long

– Part number too long

– Serial number too long

– EID number too long

MS-Q works throughout the DoD supply chain
