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.

• 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.

KW2D Series RFID Reader Functions
This section describes the functions of the KW2D Series RFID Reader.
• Read UID Function
This function reads the UID of KW2D special tags and general-purpose card type RFID tags.
• UID Verification Function
The KW2D Series RFID Reader is equipped with an RFID antenna (13.56 MHz band) and can verify UIDs read from RFID cards against
UIDs that were registered in advance. The following three types of IC tag standards are supported.
• Read Confirmation Function
The read status of the RFID tag can be confirmed with the buzzer.
• Status Confirmation Function
The operating status and error status of the KW2D Series RFID Reader can be checked with the three colors of LED indicators (white,
green, and red) on the front of the KW2D Series RFID Reader.
IC Tag Standard Non-contact IC Card/Tag Name
ISO/IEC 14443 Type A MIFARE (NXP)

System Configuration
There are two system configurations for using theKW2D Series RFID Reader: the system configuration used for actual operation and the
system configuration for creating a project for operation.
Use the KW RFID Configurator dedicated configuration software to create a project.
• System Configuration During Operation
The KW2D Series RFID Reader can be used in the following system configuration. The devices that can be connected depend on the
model. For details, see "Chapter 2 Product Specifications" on page 2-1.
• System Configuration During Project Creation
To use the KW2D Series RFID Reader, you must download a project to it.
Use the KW RFID Configurator to create the project. You can connect the KW2D Series RFID Reader to a computer and download the
created project over Ethernet communication.

Introduction to the KW RFID Configurator
The KW RFID Configurator is dedicated software for the KW2D Series RFID Reader to monitor tag information read by the KW2D Series
RFID Reader, configure the KW2D Series 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 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 RFID Reader, you can search for its IP address. The default IP address of the KW2D
Series RFID Reader is 192.168.1.50.
• Create Project
Create the tag list and configure the KW2D Series RFID Reader settings.
If necessary, create the tag list while monitoring the KW2D Series RFID Reader.
•RFIDReaderMonitor
You can monitor the status of the KW2D Series RFID Reader and the UIDs.

Overview of Communication Functions
The Ethernet port is standard equipment on the KW2D Series RFID Reader to enable communication using Ethernet. There are a total of
five connections that can be used for various communications: three Modbus TCP server connections and two maintenance
communication server connections.
• Communication Functions
• Communication Interface
Modbus TCP Server
Modbus TCP server can be used to exchange data between the KW2D Series RFID Reader and a host
device that supports the Modbus TCP client protocol. For details, see "Chapter 5 Modbus TCP Server" on
page 5-17.
Maintenance Communication
Server
Maintenance communication server can be used with a computer or PLC to upload and download
projects and to monitor UIDs detected by the KW2D Series RFID Reader. For details, see "Chapter 5
Maintenance Communication Server" on page 5-21.
Find RFID Readers If you forget the IP address of a KW2D Series RFID Reader, you can find the RFID readers connected to
the network. For details, see "Chapter 4 [RFID Reader List] Dialog Box" on page 4-14.
Ethernet Port
The KW2D Series RFID Reader can communicate with Ethernet communication-compatible host devices

• The tag reading distance is the value using a standard IDEC tag placed near the center of the reader. The tag reading distance
changes with the tag and operating environment.
• The listed value is that in an ideal environment that is not affected by radio waves and metals in the surrounding area. Carefully
check the performance of this product in your environment.
• For installation, see "Chapter 3 Installation and Wiring Precautions" on page 3-1.
