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 decoder can still
decode any bar code, the expression was possibly rejected.
•
When programming the multicode expression via parameter bar code, the PL4507 generates beeps. If any of
the following beeps do not sound during programming, an error occurred (see
for error
indicators):
•
Scanning the
Multicode Expression
bar code produces a two-tone (same pitch) beep.
•
Scanning each value of the expression produces a two-tone (same pitch) beep.
•
Scanning the
End Of Message
bar code produces a four-tone (high-low-high-low) beep.
•
Check the expression for syntax errors.
•
Try programming a simple expression to ensure the syntax is correct. See
•
for additional hints.
Troubleshooting Multicode Mode Scanning and Decoding
Use the following suggestions if encountering problems using multicode mode:
•
If the PL4507 appears to decode any single bar code instead of the intended multiple bar codes, ensure you
enabled
. Programming the multicode expression does not enable multicode
mode.
•
When specifying
Region
, ensure:
•
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
ensure the PL4507 supports the code type. Try decoding a single bar code
without using multicode. If it does not decode try enabling the bar code type. See
•
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 PL4507 can decode this new expression. Continue adding to the expression
until it fails to decode as expected, indicating the source of the error.
