5 - 20 DS3578 With FIPS Digital Scanner Product Reference Guide
PDF Prioritization
Parameter # F1h CFh
Enable this feature to delay decoding a 1D bar code (Code 128) by the value specified in PDF Prioritization
Timeout. During that time the digital scanner attempts to decode a PDF417 symbol (e.g., on a US driver's license),
and if successful, reports this only. If it does not decode (can not find) a PDF417 symbol, it reports the 1D symbol
after the timeout. The 1D symbol must be in the device’s field of view for the digital scanner to report it. This
parameter does not affect decoding other symbologies..
PDF Prioritization Timeout
Parameter # F1h D0h
When PDF Prioritization is enabled, this timeout specifies how long the digital scanner attempts to decode a
PDF417 symbol before reporting the 1D bar code in the field of view.
Scan the following bar code, then scan four digits from Appendix E, Numeric Bar Codes that specify the timeout in
milliseconds. For example, to enter 400 ms, scan the following bar code, then scan 0400. The range is 0 to 5000
ms, and the default is 200 ms.
NOTE
The 1D Code 128 bar code lengths include the following:
• 7 to 10 characters
• 14 to 17 characters
• 27 to 28 characters
In addition, a Code 39 bar code with the following lengths are considered to potentially be part of a US driver’s
license:
• 8 characters
• 12 characters
