* The setting of the online and offline mode
* The criterion setting after reading the EAS code from Tag
A Tag returns 256-bit fixed data. When there are the certain
coincidences on a percentage basis, Reader/Writer sets whether or
not to detect EAS bit as un-negated (EAS bit disabled processing)
Tag. The smaller the value is, less severe the criterion is. The initial
value is 25%.
* When Reader/Writer setting judges EAS bit un-negated in the
offline mode, Reader/Writer sets ON time of External Output 1
(OUT1) which is to be connected to a lump and a buzzer, etc.
The initial value of output time is 500 ms.
