6. Operating the reader
When there are more than one hundred tags in the eld at the same time, the application can be optimized for
Frequency of reading speed or reliability of reading.
When optimized for frequency of reading, the number of readings is maximized. In this case the same tag can be read
several times, because all tags will be reset in the inventory, so that they will respond again. Because of reading the
same tag multiple times in a scenario of moving tags it could happen that not all the tags crossing the antenna eld can
be read.
The frequency of detection of the same tag is increased.
Optimization for reliability of reading can be used to read as many different tags as possible.
When this setting is chosen, tags already detected are not read again in the next inventory as long as the tag is
powered.
So only tags in the eld that are not detected yet are read. The probability to read all the tags is increased.
• Vehicle identication (barrier)
o Application for detecting and describing individual tags in the antenna eld, which are not moving
o the distance between the tags and the antenna should be less than a few metres
• Shelving application
o Application for detecting and describing very many tags in the antenna eld, which are not moving
o the distance between the tags and the antenna should be less than 1 m
• Personal identication
o Application for detecting multiple tags in the antenna eld, which are moving at not more than 3 m/s
o the distance between the tags and the antenna should be less than 1 m
If there are more applications than t on the screen, the buttons alongside the applications are activated to allow
scrolling.
When the max. read frequency is set, for every detection (inventory) all tags are reset in order to read
them afresh. Under some circumstances the time allowed for detecting the tags may be insufcient,
so that some transponders are not detected. The frequency for detecting the tags should then be increased.
When the max. read reliability is set, tags that have already been read are not reset at every detection
(inventory), provided they are still being supplied with power. This means that only those tags which
have not yet been registered are detected. The condence that all tags are read is thus increased.
Clicking on the Apply settings button saves the settings that were made, as well as the settings for the selected application,
in the selected parameter set. This is done by rst resetting them to the factory settings and thus overwriting the previous
conguration. This must be acknowledged. Success is indicated by a the Apply settings button glowing briey, and by
display of a success message in the status window. If the process fails, the button glows briey orange for a warning or briey
red for an error (and if the failure was due to an entry being omitted, in addition the eld that is lacking the entry glows red),
and by display of a warning description or error description in the status window.
If the settings have been loaded successfully, a switch can now be made to the Basic reading tab and the read process
can be started.
