12 Intelleflex Confidential
Q value:
This value defines the number of time slots that are included in a Query. Total time slots = 2
Q
.
On average having more slots than tags in the field is better than having too few. On a general rule of
thumb using twice as many slots as tags works well, with the exception of very large populations of tags.
Tx ant:
Select transmit antenna
Rx ant:
Select receive antenna
Performance Profile:
Changing this value will change the performance of the system; by selecting
“High Speed/Low Sensitivity” the system will perform inventories as fast as possible at the expense of
read distance. “Medium Speed & Sensitivity” is a middle balance between speed and read distance.
“Low Speed / High Sensitivity” is going to perform very slowly relative to the other two, but will maximize
read distance and performance in challenging RF environments.
Loop:
Check this box for the reader to repeatedly execute the defined set of config lines. Leave it
unchecked to execute each defined config line once and only once, before stopping reads.
Search Results
Figure 3.5-2 Search Results with a tag Found
The black window on the left shows the tag ID of each tag, as it is read. Text from this window may be
copied into a document, if needed. The window holds the last 100 tag IDs read.
The summary window on the right displays the unique tag IDs of identified tags, number of times that tag
was read, the config line that most recently found the tag, the tag type (C3 or C1G2), and the dBm value
of the Received Signal Strength Indicator (RSSI). Each field may be sorted by clicking on the
corresponding gray header (i.e. to sort by protocol, click “Type”).
A summary of reads is also displayed above the unique tag reads window. At the top right corner of the
Find Tags window, the Last Operation Result section displays the status of the most current command,
giving the user some real time feedback on reader operation.

Basic Memory Reader and Write Demo
The web based demonstration page includes a simple tag memory management page that allows you to
read and write hexadecimal data in and out of the tag memory. Access to the memory is given by “Block”
address and an offset. In all Intelleflex XC3 tags there is 60 kilobits of user memory that is broken up
into 60 1kbit “Blocks”. To access the “Manage Tag Memory” section on the Demo page, find a tag and
double click on the tag in the search results viewing area. The window in Figure 3.6-1 will show after
double clicking on the tag.
