6. HOW TO COMMUNICATE WITH ID TAGS

6.3.2 Auto

6 - 15
With the auto communication specification, communication is performed while the ID
tag is being moved.
1. When the ID instruction execution request (Y14, Y1C) is turned ON, ID tag detection
is started.
2. When an ID tag enters within the antenna communication area, communication with
the ID tag is started.
3. After communication with the ID tag ends, ID instruction complete (X4, XC) turns
ON.
4. When the ID instruction execution request (Y14, Y1C) is turned OFF, ID instruction
complete (X4, XC) turns OFF and the module changes to a standby state.
5. With the auto communication specification, communication cannot be performed
normally and error detection (X5, XD) turns ON when multiple ID tags are within the
antenna communication area at once. Thus, make sure there is only one ID tag
within the antenna communication area.
