6. HOW TO COMMUNICATE WITH ID TAGS

6.3 Control Methods According to Communication Specification

6.3.1 Trigger

ID instruction execution request (Y14, Y1C)
6 - 14
With the trigger communication specification, communication is performed with the ID
tag stopped within the antenna communication area.
1. When the ID instruction execution request (Y14, Y1C) turns ON, communication with
the ID tag is started.
2. After communication with the ID tag ends, ID instruction complete (X4, XC) turns
ON.
3. 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.
4. If an ID tag does not exist within the communication area of the antenna the moment
the ID instruction execution request (Y14, Y1C) is turned ON, error detection (X5,
XD) turns ON.
With the trigger communication specification, communication cannot be performed
normally and error detection (X5, XD) turns ON when multiple ID tags are within the
antenna communication area. Thus, make sure there is only one ID tag within the
antenna communication area.
