6. HOW TO COMMUNICATE WITH ID TAGS
6.3.2 Auto
With the auto communication specification, communication is performed while the ID
tag is being moved.
1. When the ID command execution request (RYn4) is turned ON, ID-BUSY (Rxn3) is
turned ON and 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 command complete (RXn4) turns ON.
4. When the ID command execution request (RYn4) is turned OFF, ID-BUSY (RXn3) and
ID command complete (RXn4) turns OFF and the module changes to a standby state.
5. With the auto communication specification, communication cannot be performed
normally, bit 12 of the error details storage area (RWrm+1H) turns ON, and error
detection (RXn5) 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.
If the time set in the auto system command wait time setting area (RWwm+3H)
elapses during waiting for the communicable ID tag, bit 10 of the error details
storage area (RWrm+1H) turns ON and error detection (RXn5) turns ON.
