Multicode Troubleshooting

Troubleshooting Multicode Expression Programming
Use the following suggestions if encountering problems programming a multicode expression:
•
Ensure the expression is valid. Invalid expressions are rejected during programming. When an
expression is rejected the previous expression remains intact. If after programming the expression the
digital scanner can still decode any bar code, the expression was possibly rejected.
•
When programming the multicode expression via parameter bar code, the digital scanner generates
beeps. If any of the following beeps do not sound during programming, an error occurred (see
on page 2-2
• Scanning the
• Scanning each value of the expression produces a two-tone (same pitch) beep.
• Scanning the
•
Check the expression for syntax errors.
•
Try programming a simple expression to ensure the syntax is correct. See
Expressions.

Troubleshooting Multicode Mode Scanning and Decoding
Use the following suggestions if encountering problems using multicode mode:
•
If the digital scanner appears to decode any single bar code instead of the intended multiple bar codes,

When specifying
• Coordinates are within range the 0-100 decimal (or 0x00 - 0x64 hexadecimal).
• Top, Left is above Bottom, Right. Top, Left is 0,0 (0x00, 0x00 hexadecimal), and Bottom, Right is
100,100 (0x64, 0x64 hexadecimal).
• Regions for two or more bar codes do not overlap.

When specifying

Symbologies.
•
Experiment with simpler expressions, then add to it until you discover the source of the error. For
example try the simplest expression (see
you can scan a single bar code. If so, extend the expression by adding a second bar code, specifying a
region, or specifying the code type. Verify that the digital scanner can decode this new expression.
Continue adding to the expression until it fails to decode as expected, indicating the source of the error.
