• 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 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).
• 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.
• Error in Auto Mode will occur when the input to the ID Flag Sensor has errors such as the external input error or address set-
ting error at the time to start the communications with the RF Tag. In this case, the ID Flag Sensor will turns ON"0" the ERR
output and will store the error code in the data output bits (OD0 to OD15) in Normal Read Mode, or will store FFFF hex(ON all
bits) in Read Mode with Wire-saving mode. The Data Display LED(0 to 15) corresponding to the error code will be lit red.

Before starting communications with the RF Tag, turn OFF the R/W input and set the address shift
input bits (ADR0 to ADR2).
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.
After the RF Tag is out of the communications area of the Antenna, the NORMAL/STRB output
and data output bits (OD0 to OD15) will be turned OFF after the time set for the OFF delay 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.
