7-4
In the operation time, there are TAT (Turn Around Time) and communication time between the Read/Write antenna and ID tag.
(1) One tag
The communication designation is SU. N is the number of bytes. In case of Trigger, Auto and Repeat command.
Command
Communication time (ms)
Read
Write (without verification read)
t = 11 + 0.03 * N
Write (with verification read)
t = 11 + 0.06 * N
ID code read
t = 10
Communication test
t = 1,100
Correct Usage
Communication speed (a maximum of 115.2 kbps) between a host device and antenna is faster than that between an
antenna and tag. So, if the tags move to the front of the antenna one after another, use the polling command.
