Communications
 COPY (CP)
The COPY command reads data from the memory of a Tag using one Antenna and writes it to the
memory of the Tag in the other Antenna's communications area. This command cannot be used with
the V680-CA5D01-V2.
 1:1 Protocol
The communications designation for the Antenna that reads data is always single trigger (ST). The communications
designation specified in the command is used for the Antenna that writes data.
For a communications designation that specifies repeating, data writing will be repeated for other Tags after data is writ-
ten to the first Tag.
Note: When using the multi-access trigger communications designation (MT), the ID controller returns
an end code of 03 after communicating with all Tags.
Communications
designation
Specifies the method of communications with the Tag.
Refer to Communications Designation Function for details on the communications designation.

Data designation Always “H”.
Antenna designation Specifies the Antenna with which to communicate.
“1”: Reads from Antenna 1 and writes to Antenna 2.
“2”: Reads from Antenna 2 and writes to Antenna 1.
UID A unique identifier used to identify Tags.
Only in the case of the selective communications designation (SL), the UID of the Tag that is
being written to is added to the data.
Read area start address Specifies the start address of the area in the Tag from which data is to be read from in 4-digit
hexadecimal.
Setting range: 0000
H to FFFFH
No. of bytes to copy Specifies the number of bytes of data to copy in 4-digit hexadecimal.
Setting range: 0001
H to 0800H
Destination start address Specifies the start address of the area in the Tag to which data is to be written in 4-digit hexadec-
imal.
Setting range: 0000
H to FFFFH
