• When ID command execution request (Y14, Y1C) is turned on, the command specified in Command code
specification area (Un\G0, Un\G4000) is executed. ( Page 125 ID command execution request (Y14,
Y1C))
• Specify the execution timing in Communication specification area (Un\G1, Un\G4001). ( Page 66
Communication Specification)
• The area from Un\G0 to Un\G1123 is used for the buffer memory of CH1, and the area from Un\G4000 to
Un\G5123 is used for the buffer memory of CH2. ( Page 126 List of buffer memory addresses)

0000H Reads data from an RF tag.
0001H Writes data to an RF tag.
0002H Sets 1 to the bit specified in data of an RF tag.
0003H Sets 0 to the bit specified in data of an RF tag.
0004H Protects the RF tag data area that you do not want overwritten
and writes other data.
0005H Writes an addition or subtraction calculation result (data) to
data of an RF tag.
0006H Initializes data of an RF tag by using specified data.
0007H Checks whether or not an error occurred in data of an RF tag.
0008H Judges whether or not the number of RF tag writes exceeds the
specified number of EEPROM-type RF tag writes.
0009H Copies data of an RF tag between channel 1 and channel 2.
000AH Reads data and check codes from an RF tag, inspects data
reliability, and corrects 1-bit errors.
000BH Writes data and check codes for inspecting data reliability to an
RF tag.
000CH Reads the UID (unit identification number) of an RF tag.
0010H Measures the noise around an antenna.
