• 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.
• 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 communi-
cation process caused by passing the RF Tag quickly in the communications area of the Antenna before completing the com-
munication or interfering by electrical noise. Be sure to check the communications carefully when installing the system.

Normal completion
Before starting communications with the RF Tag, turn OFF the R/W input.
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 com-
munications 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 will store the read data in the data output bits (OD0 to OD15). The
Data Display LED (0 to 15) corresponding to the read data will be lit green.
The NORMAL/STRB output will be turned OFF after the time set for the fixed time in the output
mode time setting has elapsed.
The data output bits(OD0 to OD15) and the Data Display LED(O to 15) will be held until next data
is output. 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.
