7
Read no new tags.
8
Read 1 new tag.
9
Switch back to antenna one.
10
Read no new tags.
11
Read 2 tags.
The total number of ID tries = 2 * 2 = 4.
Setting INITTRIES
When you choose the value for INITTRIES, you need to decide if you want
INITTRIES to be 1 or greater than 1:
•
The previous examples assume that INITTRIES is set to 1.
•
This section describes how the reader operates when INITTRIES is greater than
1. In this case, the INITTRIES attribute tells the reader how many resets
(initialize) commands should be sent. However, this does not mean how many
are sent at one time. INITTRIES actually works as a multiplier of IDTRIES and
ANTTRIES.
Suppose these attributes are set:
•
INITTRIES=3
•
IDTRIES=2
•
ANTTTRIES=6
•
ANTS=1,2
The reader performs these steps:
1
Turn on antenna one.
2
Send an initialize command on antenna 1 and 2.
3
Read no new tags.
4
Read 1 new tag.
5
Switch to the next antenna.
6
Read no tags.
7
Read no tags.
8
Send an initialize command on antenna 1 and 2.
9
Read 3 new tags.
10
Read 2 new tags.
11
Switch to the next antenna.
12
Read 1 tag.
13
Read 2 tags.
14
Send an initialize command on antenna 1 and 2.
15
Read 2 new tags.
16
Read 2 new tags.
