Period during which the transponder ignores modulated signals after an EOF signal transmitted from the
reader/writer : tmit
After detection of an EOF signal sent from the reader/writer, each transponder must ignore the 10
%
modulated
signals from the reader/writer for a time (tmit).
tmit begins at the rising edge of the EOF pulse. The minimum value of tmit is defined as 4384/fc (323.3
μ
s)
+
tnrt, as shown in the following table.
In the above expression, tnrt stands for the response time of the transponder.
Period during which the reader/writer waits before sending a request : t2_a
After a response to a request (except a Inventory command or a Stay Quiet command) from a transponder has
been received, the reader/writer must wait for a certain period (t2_a) before sending the next request. The
minimum value of t2_a is shown in the following table.
If the reader/writer sends a Stay Quiet command to a transponder, the transponder does not return any response.
In this case, t2_a begins at the point at which 9.44
μ
s has passed since the rising edge of the EOF pulse for the
Stay Quiet command.
If the reader/writer sends an Inventory command to a transponder, the wait time t2_a follows the specifications
of t2inv (period during which the reader/writer waits before sending a request during execution of the Inventory
command) described below.
Period during which the reader/writer waits before sending a request during execution of the Inventory com-
mand : t2inv
While an Inventory command is being executed, the reader/writer sends an EOF signal when it shifts to the next
slot. In this case, the wait time is defined as follows depending on whether transponders return responses :
-
Wait time applied when the reader/writer has received one or more responses : t2invwr
When the reader/writer has received one or more responses, the reader/writer must wait until responses
from the transponders have been completed (that is, the reader/writer receives an EOF signal or tnrt passes).
After that, the reader/writer must wait until t2_a passes before sending an EOF signal to switch to the next slot.
-
Wait time applied when the reader/writer has not received any responses : t3_a
When the reader/writer has not received any responses from the transponders, the reader/writer must wait
until t3_a passes before sending an EOF signal. In this case, t3_a begins at the rising edge of the EOF pulse
that was sent previously. The minimum value of t3_a is defined as 4384/fc (323.3
μ
s)
+
tnrt, as shown in the
following table.
