• At least 10 ms is required for enabling INHIBIT/TRIG input as operation prohibit or clear the data.
• Wait at least 10 ms after switching the R/W input line before performing next process.
• 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.
• In Auto Mode, the ID Flag Sensor does not output the error in case when the ID Flag Sensor can not complete the communication
process caused by passing the RF Tag quickly in the communications area of the Antenna before completing the communication or
interfering by electrical noise. Be sure to check the communications carefully when installing the system.

Reference data and

Before starting communications with the RF Tag, turn OFF the R/W input, set the reference data on the data
input bits (ID0 to ID15).
Turn OFF the INHIBIT/TRIG before starting communications.
The ID Flag Sensor will start communications with the RF Tag when the RF Tag enters 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
indicators (0 to 15) corresponding to the reference data will be lit green.
The NORMAL/STRB output and the data output bit(OD0) will be turned OFF after the time set for the fixed time
in the output mode time setting has elapsed. The NORMAL/STRB output , the data output bits (OD0 to OD15)
and the Data Display LED can be unconditionally cleared by turning ON the INHIBIT/TRIG input.
The ID Flag Sensor will start communications with the RF Tag when the RF Tag enters 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 indicator will be lit red, and the data
indicators (0 to 15) corresponding to the reference data will be lit green.
The NORMAL/STRB output and the data output bit(OD7) will be turned OFF after the time set for the fixed time
in the output mode time setting has elapsed. The NORMAL/STRB output , the data output bits(OD0 to OD15)
and the Data Display LED can be unconditionally cleared by turning ON the INHIBIT/TRIG input.
