RFID System
User's Manual
In
• The maximum communications distance can be obtained when the Antenna faces the RF tag directly.
When the Tag is installed at a tilt, the communications distance is reduced. Consider the effect of the
Tag at a tilt when installing the Tag.
• Provide the mounting distances between plural RF tags to prevent them from malfunctions due to
mutual interference.
• If the central axis of an antenna and RF tag shifts, a communications distance will fall.
3. Storage
Do not store the Products in the following locations.
• Locations exposed to direct sunlight
• Locations exposed to corrosive gases, dust, metallic powder, or salts
• Locations not within the specified storage temperature range
• Locations subject to rapid changes in temperature or condensation
• Locations not within the specified storage humidity range
• Locations subject to direct vibration or shock outside the specified ranges
• Locations subject to spray of water, oil, or chemicals
• Locations subject to filled with steam
4. Cleaning
• Do not clean the Products with paint thinner or the equivalent. Paint thinner, benzene, acetone, and
kerosene or the equivalent will dissolve the resin materials and case coating.
5. Combination of the Amplifier
• With the amplifierV680-HA63A use only the RF tags of V680-D1KP52MT, V680-D1KP52M-BT01,
V680-D1KP52M-BT11, V680-D1KP53M, V680-D1KP54T, V680-D1KP66T, V680-D1KP66MT, V680-
D1KP66T-SP, or V680-D1KP58HTN. Do not use these RF Tags together with the V680-HA63B Ampli-
fier.
6. Use at high temperatures (V680-D1KP58HTN)
• Data stored in memory in the RF Tag may be lost due to the characteristics of EEPROM, if the accu-
mulated usage time of the RF Tag at a high temperature over 125
°
C exceeds 10 hours after writing
data to the RF Tag.
• Do not communicate between the Antenna and the RF Tag in an environment where the ambient
operating temperature is 85
°
C or higher.
An error in communications between the Antenna and the RF Tag may occur.
• Do not use the commands using UID (unique identification number for each RF Tag) when the RF tag
is used at a high temperature over 125
°
C. The UID may be lost due to the characteristics of
EEPROM.
•Do not use the READ ID command (command code: ID).
•Do not make the UID Addition Setting (command code: US).
•Communications specifications (FIFO trigger, FIFO repeat, multi-access trigger, multi-access repeat,
and selective) can not be used.
For Use at high temperatures, refer to RF Tags - Use at high temperatures (V680-D1KP58HTN) in Section 2 Specifica-
