Parameter Precedence Change function
The operating order of the relevant parameters used in success decoding bar code data with the
decoder learning function can be advanced for precedence. This advance will result in quick
response of continuously scanning multiple bar codes with similar quality. Since the precedence
order will be stored in the RAM memory, it will be reset to the default order if RESET is
performed on the terminal.
Erratic Scanning Avoidance function
This function fetches the bar code quality rank by calculating the decoder easiness when scanning
a bar code. If the quality rank of scanned bar code is relatively low, the error rate will become
high causing an erratic scanning to occur. To suppress the error rate, the function automatically
makes judgment on scanning with such the bar code as “Failure”.
3.2.7 Power Control
In order to save the power, the power will not be supplied to the laser scan module and the ASIC
module for laser beam control during the laser beam is not irradiating. It will be supplied to these
modules when the laser beam is to be irradiated, and turned off again when the laser beam is not
irradiated.
