Advanced Data Formatting 11 - 5
And the SECOND rule states:
When scanning a Code 128 bar code of length 12, send the first four characters, then send the ENTER key,
then send all remaining data.
If a Code 128 bar code of length 12 were scanned, the THIRD rule would be in effect. The SECOND rule would
appear to not function.
Note also that ADF rules are actually created when using the standard data editing functions. Scan options are
entered as ADF rules, and the hierarchy mentioned above also applies to them. For the digital imager scanner,
this applies to prefix/suffix programming in the parameter Scan Data Transmission Format.
These rules reside in the same “rule list” as ADF Rules, so the order of their creation is also important.
Default Rules
Every unit has a default rule to send all scan data. Units with custom software may have one or more default
rules burned in. The rules hierarchy checks user programmable rules first, then the default rules. Default rules
can be disabled by entering the following general rule in the user programmable buffer:
When receiving scan data, send all data.
Since this rule always applies, ADF will never go into the default rules.
Special Commands
Pause Duration
This parameter, along with the Send Pause parameter on page 11-27, allows a pause to be inserted in the data
transmission. Pauses are set by scanning a two-digit number (i.e., two bar codes), and are measured in 0.1
second intervals. For example, scanning bar codes “0” and “1” inserts a 0.1 second pause; “0” and “5” inserts a
0.5 second delay. See Appendix D, Numeric Bar Codes. To correct an error or change a selection, scan
Cancel on page D-2.
