• Wait at least 10 ms after switching the R/W input line before performing next process.
• Switch the address shift input (ADR0 to ADR2) at least 10 ms before accessing the RF Tag(e.g., at least 10 ms before turning
ON the trigger input).
• Switch the reference data input (ID0 to ID15) at least 10 ms before accessing the RF Tag(e.g., at least 10 ms before turning
ON the trigger input).
• Read the data output(OD0 to OD15) after the NORMAL/STRB output turns ON.

Turn OFF the R/W input before starting communications with the RF Tag, set reference data on
the data input bits (ID0 to ID15), and set the address shift input bits (ADR0 to ADR2).
Turn ON the INHIBIT/TRIG input to start communications with the RF Tag after confirming the RF
Tag is in the communications area of the Antenna.
If communications with the RF Tag are completed normally, the ID Flag Sensor will turn ON the
NORMAL/STRB output and the data output bit (OD0: data match). The VERIFY OK/NG indicator
will be lit green, and the Data Display LED (0 to 15) corresponding to the reference data will be lit
green.
When you turn OFF the INHIBIT/TRIG input, the NORMAL/STRB output and the data output bit
(OD0) will be turned OFF.
Turn ON the INHIBIT/TRIG input to start communications with the RF Tag after confirming the RF
Tag is in the communications area of the Antenna.
If communications with the RF Tag are completed normally, the ID Flag Sensor will turn ON the
NORMAL/STRB output and the data output bit (OD7: data mismatch). The VERIFY OK/NG indi-
cator will be lit red, and the Data Display LED (0 to 15) corresponding to the reference data will be
lit green.
When you turn OFF the INHIBIT/TRIG input, the NORMAL/STRB output and the data output bit
(OD7) will be turned OFF.
