• At least 10 ms is required for INHIBIT/TRIG input.
• Write function can not be used in the Trigger Mode3. R/W input is ignored.
• If communications control will be performed using only data output lines without using the NORMAL/STRB output, for exam-
ple, implement programming for a timer with a specified time, check the status of each data output line at each specified time,
and read the outputs as data after the data is all zeros or all ones.
• All ones and all zeros of data outputs cannot be used as data.
• All data output bits will be ON when an error occurs, not to output error code. The Data Display LED(0 to 15) will flash the error
code in red corresponding to the occurring error.

Turn ON the INHIBIT/TRIG input to start communications with the RF Tag.
If communications with the RF Tag are completed normally, the ID Flag Sensor will turn ON the
NORMAL/STRB output , store the parity value in the PARITY output, and 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 PARITY 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.
Turn ON the INHIBIT/TRIG input to start communications with the RF Tag.
If communications with the RF Tag are completed with an error, the ID Flag Sensor will turn ON
the ERR output , store the parity value("0") in the PARITY output, and store FFFF hex(ON all bits)
in the data output bits(OD0 to OD15). The Data Display LED(0 to 15) corresponding to the read
data will be lit red.
The ERR output and PARITY 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.
