5-2 Control Procedures for Each Communication
5-2
5-6
5-2-1-3 Single Repeat Mode: ISO Mode
The Reader/Writer waits for a Tag to enter the R/W Antenna’s communications area. Every
time a Tag enters the communications area, the Reader/Writer communicates with the Tag and
returns a response. It is not until communications are stopped by the Stop(ST) or Reset(XZ)
command that the Reader/Writer accepts the next command.
Operation in I.CODE1 mode
●
Do not operate the function in I.CODE1 mode. If a function equivalent to ISO mode, i.e., a function that
always returns a response, is required for the area confirmation and other purposes, a single command (Tag
code = 0) by Fast Read Access should be used.
(If the function is executed in I.CODE1 mode, the Reader/Writer will perform the process only once at the Tag’s
entry to the communication area and return a response. Multiple Tags in the communication area may result in a
response with abnormal read data).
