6.3. Basic read functions
This index card is divided into two columns, the rst column contains a table with information about the read tags, and
in the second column you can nd the controls, which control the reading process.
The table next to the Electronic Product Code (EPC), you can nd the following information:
1 Length - indicates the length in bits of the EPC, valid lengths 0-496 bit
2 EPC - EPC of the tag in hexadecimal representation
3 Antenna - tag was read over this antenna post, valid values 1-4
4 RSSI - is the unitless (shown as having no units) signal strength of the tag response, valid values 0-255
5 Readings - shows how many times this tag has been read successfully
6 Cycles - indicates how often an inventory was started
7 Last reading - is the timestamp of the last reading of the Tag
8 First reading - is the timestamp of the rst reading of the Tag
The appearance and disappearance of the Tag is shown in colour in the eld for better visual effect.
When a tag appears in the eld, the row is represented by the green tag information, when it disappears the row is red.
The control of the reading process takes place in the second column of the index card. A distinction is made between
two different modes. These can be selected by selecting „synchronous“ and „asynchronous“. The description of these
two modes is done on the following pages.
The second column can be sorted by the read result (unique) tags. This is especially useful in multi-antenna applica-
tions. For example, with a gate application with 4 antennas read per pallet with 100 tags, then the maximum number
of reading results will be 400. Since not all tags are read by all antennas, the reading results in general, will level off at
about 250. In order to detect how many different tags have been read, the selection „sort by unique tags“ can be made.
