KW9Y-B2163
Thank you for purchasing this IDEC product. Before using this product, please confirm that there are no mistakes with your order.
Carefully read this manual and use this product correctly.
Safety Precautions
• Read the "KW2D Series User’s Manual" to ensure correct operation before starting installation, wiring, operation, maintenance, and
inspection of the KW2D Series.
•If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• All KW2D Series modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or failsafe
provision to the control system when using the KW2D Series in applications where heavy damage or personal injury may be caused, in
case the KW2D Series should fail.
•Implement security measures, such as those for unauthorized access to this product from external devices, on the network system
side. IDEC Corporation bears no responsibility for losses, damages, and/or other expenses that occur directly or indirectly as a result of
unauthorized access or other security failures.
•As a security measure, always use a firewall or another tool and block accessible IP addresses and ports.
•In this manual, safety precautions are categorized in order of importance:
Warning notices are used to emphasize that improper operation may cause severe personal injury or death.
Caution notices are used where inattention might cause personal injury or damage to equipment.
•This product is not designed for use in applications requiring a high degree of reliability and safety, such as applications for
medical devices, nuclear power, railroads, aerospace, and automotive devices. The KW2D Series should not be used for
such applications.
•Turn off power to the KW2D Series before installation, removal, wiring, maintenance, and inspection of the KW2D Series.
Failure to turn power off may cause damage, electrical shocks or fire hazard. If such a circuit is configured inside the
KW2D Series, Failure of the KW2D Series may cause disorder of the control system, damage, or accidents.
•Special expertise is required to install, wire, and operate the KW2D Series. People without such expertise must not use
the KW2D Series.
• Install the KW2D Series according to the instructions described in the "KW2D Series User’s Manual". Improper installation
will result in falling, failure, or malfunction of the KW2D Series.
• Install the KW2D Series in environments described in the "KW2D Series User’s Manual". If the KW2D Series is used in
places where the KW2D Series is subjected to high-temperature, high-humidity, condensation, corrosive gases,
excessive vibrations, or excessive shocks, then electrical shocks, fire hazard, or malfunction will result.
•Prevent the KW2D Series from falling while moving or transporting the KW2D Series, otherwise damage or malfunction of
the KW2D Series will result.
•Wiring must use lead sizes that are appropriate for the applied voltage and current.
•Prevent metal fragments and pieces of wire from dropping inside the KW2D Series housing. Put a cover on the KW2D
Series modules during installation and wiring. Ingress of such fragments and chips may cause fire hazard, damage, or
malfunction.
•Use SELV power supply that is reinforced or double-insulated from MAINS without any risk of electric shock, and Limited
Energy (LIM) Circuit.
•Do not disassemble, repair, or modify the KW2D Series modules. There is a risk of serious accident, such as electric
shock, damage, fire, and malfunction.
This device complies with part 15 of FCC Rules and Innovation, Science and Economic Development Canada’s licence-
exempt RSS(s). Operation is subject to the following two conditions: (1) this device may not cause harmful interference,
and (2) this device must accept any interference received, including interference that may cause undesired operation.
Le présent appareil est conforme à la partie 15 des règles de la FCC et aux normes des CNR d’Innovation, Sciences et
Développement économique Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux
deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'appareil doit accepter tout brouillage
subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
FCC CAUTION
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority
to operate the equipment.
• Electromagnetic waves are generated from the front unit, so—excluding when using tags—stay more than 5 cm away
from the front unit.
•When disposing of the KW2D Series, do so in accordance with national and local regulations.

Introduction to the KW RFID Configurator
The KW RFID Configurator is dedicated software for the KW2D Series Smart RFID Reader to monitor tag information read by the KW2D
Series Smart RFID Reader, configure the KW2D Series Smart RFID Reader settings, and create tag lists. The collection of settings and
created data is called a project.
Build the environment required for operation by using the KW RFID Configurator to create a project and downloading that project to the
KW2D Series Smart RFID Reader.
The KW RFID Configurator has the following functions.
•Find RFID Readers
If you do not know the IP address of a KW2D Series Smart RFID Reader, you can search for its IP address. The default IP address of the
KW2D Series Smart RFID Reader is 192.168.1.50.
•Create Project

•Communication Interface
Modbus TCP Server
Modbus TCP server can be used to exchange data between the KW2D Series Smart RFID Reader and a
host device that supports the Modbus TCP client protocol. For details, see "Chapter 5 Modbus TCP
Server" on page 5-22.
EtherNet/IP Communication
It is possible to exchange data between a host device supporting CC-Link IE Field Basic communication
and the KW2D Series Smart RFID Reader. For more information, please refer to "Chapter 5 EtherNet/IP
Adapters" on page 5-26.
CC-Link IE Field Basic
communication
It is possible to exchange data between a host device supporting EtherNet/IP communication and the
KW2D Series Smart RFID Reader. For more information, please refer to "Chapter 5 CC-Link IE Field Basic
Slaves" on page 5-42.
Maintenance Communication
Server
Using a PC, you can upload and download the project or monitor UIDs detected by the KW2D Series
Smart RFID Reader. For details, see "Chapter 5 Maintenance Communication Server" on page 5-49.
Find RFID Readers You can find the RFID readers connected to the network. For details, see "Chapter 4 [RFID Reader List]
Dialog Box" on page 4-15.

Chapter 2 Product Specifications
This chapter describes the part names and specifications of the units that make up the KW2D Series Smart RFID Reader.
Specifications
The specifications of this product are as follows.
Operating Environment Specifications
*1 IP ratings are not applicable to UL certification.
*2. Front of panel only
*3. The protective structure of the operating part after this product is mounted on the panel. Although this poduct complies with various
testing conditions, normal operation in all environments is not guaranteed. The oil-proof structure of IP67F complies with the oil-proof
test conditions of Japanese Industrial Standards JIS C 0920 appendix. There is no guarantee for long-term use in an oil-filled
environment or use of out of specification oil. Please check by testing in advance.
Be careful when using card type KW2D special tags. These tags have a smaller temperature range than the KW2D Series
Smart RFID Reader itself. If card type KW2D special tags are used outside the specified temperature range, there is a risk
of deformation, damage, or malfunction.
