• At least 10 ms is required for INHIBIT/TRIG input.
• Wait at least 10 ms after switching the R/W input line before performing next process.
• Switch the write 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).
• The NORMAL/STRB output and ERR output will be held until the next time the trigger is turned ON if the output time setting
switch is set to CONTINUOUS.

Turn OFF the R/W input before starting communications with the RF Tag, set the write data on the
data input bits (ID0 to ID15).
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 all the data output bits(OD0 to OD15) turns OFF. The Data Display
LED (0 to 15) corresponding to the write 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.
Turn ON the INHIBIT/TRIG input to start communications with the RF Tag.
IF communications with the RF Tag are completed with an error(No RF Tag error in this case), the ID
Flag Sensor will turn ON"0" the ERR output, and all the data output bits (OD0 to OD15) turns OFF. The
Data Display LED(0 to 15) corresponding to the error code will be lit red.
The ERR output will be turned OFF"1" after the time set for the fixed time in the output mode time
setting has elapsed.
