5-2 Control Procedures for Each Communication

5-2-3-2 Multiple Repeat Mode
Read Command (RD)
Write Command (WT) with UID/SNR addition setting enabled (Excluding I.CODE1 Mode).
The Reader/Writer continues to return a response every time it has communicated with a Tag in the
communication area. This operation continues until the Stop Command (ST) or Reset Command (XZ) has
been executed. Other commands are rejected in this state.
Write Command (WT) with UID/SNR addition setting disabled (In I.CODE1 Mode, the command with
UID/SNR addition setting enabled is also covered).
In this case, do not execute the commands in Multiple Repeat Mode. Basically, the operation in Multiple
Trigger Mode is performed repeatedly.
However, the operation may become highly complicated, depending on the Tag status.

(1)The Reader/Writer receives a
command.
(2)The Reader/Writer communicates
with the Tag.
(3)Adds UID to the response and
returns the response.
(4)The Reader/Writer communicates with
a Tag when the Tag is in the Reader/Writer
antenna communication area.
5. The Reader/Writer keeps on detecting
the Tags until the command has been
terminated by Stop Command (ST).
