mand.
“13”

“14”
Format error
The command format is incorrect.
A stop command is received in command-waiting status.
In Selective Access mode;

specified.
2) A tag detection command normal end is retried after it has been sent.
Host commu-
nications error
“18”
Frame length error
ETX is not received in 151 characters or less after STX is received.
“70”
Communications error
An error occurs during the communications with an ID Tag, and commu-
nications cannot end normally.
“71”
Write process error
Tag is in an area that can be read, but not written to.
You are trying to write to a locked page (i.e., write-protected).
The correct data cannot be written to the Tag.
Verify read results in an error.
“72”
No Tag error
No Tag is present in front of Antenna when a Trigger command is exe-
cuted.
There are multiple Tags within the communications area when using
Single Access mode.
Communica-
tions error
“79”
Command error
Refer to the correlation table of ISO/IEC Error Codes.
System error
“93”
Memory error
An error has occurred in the Reader/Writer memory.
“01”
Specified No. of Tags exceeded More Tags than have been specified in the Tag No. setting have entered
the communications area.
“02”
Specified No. of retries ex-
ceeded
Tag detection has been retried the specified number of times to find all
the Tags in the communications area, but some Tags have not been
detected.
“03”
No. of Tags exceeded
No. of retries exceeded
Two of the warning, “01” and “02,” have occurred.
“04”
Communications error
An error occurs during communicating with Tags, resulting in successful
communications with only some of the Tags.
“05”
Specified No. of Tags exceeded
Communications error
Two of the warnings, “01” and “04,” have occurred.
“06”
No. of Tags exceeded
Communications error
Two of the warnings, “02” and “04,” have occurred.
Warning
“07”
No. of Tags exceeded
No. of retries exceeded
Communications error
All the three warnings, “01,” “02,” and “04,” have occurred.
Note
The warning codes are used in a response code that is generated during the
multi-read process, in order to return read data in a Tag when a communica-
tions error occurs.
