4-6 Decode Settings
Decode Match Count settings
When the trigger is activated, the BL-N70 laser scans approximately 76 times per second.
By default, the BL-N70 must decode a barcode 2 times within a trigger period before it is
considered valid and data can be sent. If poor print quality, or other conditions are causing
problems with decode reliability, try setting the Decode Match Count to a number higher than 2.
If your application requires more speed, you can set the Decode Match Count to 1.
For most applications, the default value of 2 is sufficiently fast and reliable and does not need to
be changed.
