Product Overview
V680-A80 Attachment
This Attachment is used to hold V680-D1KP58HTN ID Tags.
Applicable model: V680-D1KP58HTN
High-temperature Applications (V680-D1KP58HTN)
Data Retention
•
Due to the characteristics of EEPROM, any data that is written to an RF Tag may be lost if it is used
in a high-temperature environment that exceeds 125
°
C for a total of more than 10 hours. Always
reset the data holding time before a total of 10 hours is reached.
•
Communications between the Reader/Writer and RF Tags may fail in high-temperature environments
of 85
°
C or higher. Do not perform communications between the Reader/Writer and RF Tag in a high-
temperature environment of 85
°
C or higher.
•
Due to the characteristics of EEPROM, the UID (RF Tag ID code) may be lost if an RF Tag is used in
a high-temperature environment that exceeds 125
°
C. Do not use commands that use the UID in
high-temperature environments that exceed 125
°
C.
•
Do not use the ID READ command.
•
You cannot use FIFO trigger communications.
