Troubleshooting Multicode Mode Scanning and Decoding
Use the following suggestions if encountering problems using multicode mode:

ensure you enabled
. Programming the multicode expression does not enable
multicode mode.
•

•
Top, Left is above Bottom, Right. Top, Left is 0,0 (0x00, 0x00 hexadecimal), and Bottom, Right is 100,100
(0x64, 0x64 hexadecimal).

•
Experiment with simpler expressions, then add to it until you discover the source of the error. For example try
the simplest expression (see
Examples of Simple Multicode Expressions
) and make sure 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.
