No Read String
This feature allows the transmission of a programmable character or string when no code has
been decoded (No read) during a reading phase (On Line Mode only).
To set this feature:
1. Determine the desired character string (maximum 20).
2. Reference the ASCII Chart on the inside back cover of this manual to find the hex value
assigned to the desired character.
3. Go to "
No Read String" on page 63
and scan ENTER/EXIT PROGRAMMING MODE to
enter Programming Mode
4. Scan the barcode: "Select No Read String."
5. Scan the hex equivalent characters from the keypad in Appendix D that represent the
desired character string in step 1 above.
6. If less than the expected string of 20 characters is selected, scan the ENTER/EXIT bar-
code to terminate the string.
7. Scan the ENTER/EXIT PROGRAMMING MODE barcode once again to exit Program-
ming Mode.
This completes the procedure.
Code Verifier
Code Verifier is available in On Line or Serial On Line and Automatic modes only. A
programmable character or string is transmitted after a successful reading phase depending on
the result of a comparison between the decoded label and a user specified label.
Code Verifier Mode
Options for this feature are:
• Disable: disable the Code Verifier functionality
• Transmit Wrong String: the reader will transmit the wrong string to the Host.
• Transmit Wrong Code: the reader wll transmit the wrong code to the Host.
If the code read matches the code verifier Match String then it is sent to the host through the
configured port. If it does not match the code verifier Match String, either the Wrong Code can
be sent or the defined Wrong String message can be sent indicating the error.
Match String
The string used as the match code for code verification. The Match String must be configured
to include start/stop characters and check digits, if their transmission is enabled.
It is possible to define the Match string by inserting:
• any printable characters
• non-printable ASCII characters available in the list inside the parameter edit box
