Preface-1 KW2D Series Smart RFID Reader User’s Manual
SAFETY PRECAUTIONS
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.
• 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:
SAFETY PRECAUTIONS
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 the 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
acircuit 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.
•When disposing of the KW2D Series, do so in accordance with national and local regulations.
•This product has been certified by the Radio Law of all countries involved. For details, refer to
"Regarding Laws and Compatible Standards" on page Preface-4.

5 KW2D Series Smart RFID Reader Functions
1-4 KW2D Series Smart RFID Reader User’s Manual
●Read UID Function
The KW2D Series Smart RFID Reader is equipped with an RFID antenna (13.56 MHz band) and can read the UID of
the KW2D special tag and the general-purpose card type RFID tag.
The following IC tag standards are supported.
●UID Verification Function
This function verifies the UID in the RFID tag against UIDs that were registered in advance. UIDs are registered on the
Tag List tab in KW RFID Configurator. Since a 1-byte authority (1 to 255) can be specified for each UID, the UID to
be registered can be distributed to 255 types of authority. A maximum of 500 items of tag information can be
registered.
The tag information obtained in verification can be read by the host device and used to restrict the operation of
equipment and to manage the usage history.
Tag Information Contents
●Status Confirmation Function
The operating status and error status of the KW2D Series Smart RFID Reader can be checked with the buzzer and the
LED indicators (white, green, and red) on the front of the KW2D Series Smart RFID Reader.
●Tag list editing function
Up to 500 tag information can be registered in the tag list of the KW2D Series Smart RFID Reader. The tag list of the
KW2D Series Smart RFID Reader can be edited by using the master tag or host device. For details, refer to Chapter 5
"2.3 Edit the tag list" on page 5-17.

ISO/IEC 14443 Type A MIFARE (NXP)
ISO/IEC18092 Type F FeliCa (Sony)
ISO/IEC15693 Type V Tag-it (Texas Instruments), I-CODE (NXP)
With the factory settings, the RFID reader detects RFID tags that support the three types of IC tag standards.
On the RFID Reader Settings tab of the KW RFID Configurator, in the Tag Read Settings, you can change
the RFID tags detected. For details, refer to Chapter 6 "IC Tag Standard" on page 6-12.
Tag Information Description Explanation
UID Maximum 10 bytes of data Except for a complete match of UID, the verification result is a failure.
Name1 Maximum 18 bytes Used to explain the UID. This information is not used by the KW2D
Series Smart RFID Reader.
Name2 Maximum 18 bytes
Authority 1 byte (1 to 255) When an unregistered UID in the tag list or a disabled UID is read, the

Overview of the KW2D Series Smart RFID Reader
There are two system configurations for using theKW2D Series Smart 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 Smart RFID Reader can be used in the following system configuration. The devices that can be
connected depend on the model. For details, refer to Chapter 2 "Product Specifications" on page 2-1.
●System Configuration During Project Creation
To use the KW2D Series Smart RFID Reader, create and download a project to it.
Use the KW RFID Configurator to create the project. You can connect the KW2D Series Smart RFID Reader to a
computer and download the created project over Ethernet communication.
6 System Configuration

7 Introduction to the KW RFID Configurator
1-6 KW2D Series Smart RFID Reader User’s Manual
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.
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.
●Create Project
You need to configure the KW2D Series Smart RFID Reader settings and create the tag list. For details, refer to
Chapter 6 "3 Projects" on page 6-15.
●Search KW2D Series Smart RFID Reader
