Tips for Verifying the Presence of a Bar Code

If the scanner is operated in the “trigger enabled” mode and the trigger is activated, one of three conditions may occur:

A bar code is scanned and decoded

Decoded data is transmitted

 

 

A bar code is scanned but is not

No data is transmitted

decoded (e.g., print quality was poor)

 

 

 

No bar code is present

No data is transmitted

 

 

In some applications, when no data is transmitted, it may be important to know why. Was there a bar code present that could not be decoded, or was no bar code present at all?

This requirement is common in applications such as automated blood analysis equipment. Test tubes containing blood samples from many different people are loaded into a rack for automatic analysis. The bar code on each tube ties that sample and the results back to a specific individual. If no bar code data is transmitted it is critical to understand the reason.

Your Opticon scanner, when operated in the Trigger Enabled mode, can be programmed to transmit an error message which indicates whether or not a bar code was present. The following table shows the message that will be transmitted for each condition.

Presence/Absence of bar code

Scanner Transmits

Bar code was present and correctly decoded

Decoded Data

No bar code was present

<STX> “?” <ETX>

 

 

Bar code was present but could not be decoded

<STX> “>” <ETX>
