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,
ensure you enabled
multicode mode.
•
When specifying
Region
• 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
Code Type
code without using multicode. If it does not decode try enabling the bar code type. See
Symbologies.
•
Experiment with simpler expressions, then add to it until you discover the source of the error. For example try
the simplest expression (see
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.
