2.4.6 Error Display Might Be Returned
Errors occur if wrong operations done:
◆
Inventory success, access failure:
There are two steps to get access to tags: firstly, tag inventory; secondly, access tags. Picture above
shows the inventory is successful, failed to access to tags.
Two reasons why:
1. Parameters incorrect: for example, zones(password/ EPC/ TID/ User) to be read do not exist.
2. Tags beyond the area that the RF could cover: distance of accessing to tags is about 60%-70% of tag
inventory; in this case, please put the tag closer to the antenna.
◆
Wrong password:
Reason why: wrong password is set.
