zDo not disassemble, repair, or modify this product. Doing so may result in electric shock, fire, or
personal injury.
Caution
Do not drop the device or apply physical shock.
zDoing so may result in personal injury or device damage.
Do not apply strong force to, or place heavy items on the device or cables.
zDoing so may deform or damage the device, resulting in electric shock or fire.
Use and store the product in an environment that is specified in the catalog or
operation manual.
zFailure to do so may cause failure of the device, electric shock, or fire. Do not use or store the
device in the following locations:
・ Locations that do not satisfy the specified operating conditions (-10°C to +40°C, 25%RH to
85%RH,non-condensing).
・ Locations that do not satisfy the specified storage conditions (-25°C to +65°C, 25%RH to

vii
To avoid interferences with other systems, adhere to the following items and check
them before using the product.
zThe product uses a publicly available ISM frequency band of 13.56 MHz to communicate with
Tags. Some transceivers, motors, monitoring devices, power supplies (power supply ICs), and
other similar RFID systems may generate noise, which cause radio interference and may affect
communication with Tags. If the product is required in the vicinity of these items, check for any
interference prior to use.
zOn the contrary, the system itself may affect radio station transmissions or medical devices. Be
cautious when using the system in the environments where such effects might occur.
zTo minimize noise effects, adhere to the following:
・
Establish a Class D grounding (former Class 3 grounding) for metal objects placed in the
vicinity of the system.
・
Keep cables away from those with high voltages or heavy currents.
Do not allow the device or cables to be soused or exposed to water.
zDoing so may result in electric shock, fire or failure of non-waterproof devices or cables.
Connect the enclosed USB cable to the product for power supply.
zFailure to do so may damage the device or generate noise that affects receiving apparatus such
as TV or radio.
Connect the enclosed USB cable only between this product and a computer.
zDo not extend or modify the connection with other USB cable or USB adaptor.
Handle the USB cable by the connector portion to prevent excessive stress on the
connector.
zFailure to do so may result in poor contact or damage the device.
Handle the USB cable by the connector portion to prevent excessive stress on the
connector.
zFailure to do so may result in poor contact or damage the device.
If the device fails or is exposed to water (non-waterproof devices or parts), or an
unusual smell, smoke, or sparks are detected, immediately refrain from using the
device and contact OMRON or a sales representative for service and repair.
zContinued use of the failed device may result in electric shock or fire.
Adhere following instruction to prevent the power supply or AC adaptor belonged
to the computer from affecting communication with tags.
zKeep the distances from the power supply or AC adaptor for the computer as described in 5-6
“Positional Relation Between Reader and Computer” when use the device.
This product is not suitable for simultaneous connection of multiple units.

3-1 Outline of Operations
The RFID Unit reads or writes to the tags using commands sent from the host
control unit, and returns the processing responses to the host control unit.
The RFID Unit has three operating modes. The conditions for changing the
mode are shown in the following diagram.
(1) Command waiting mode
In this mode, the COM port is open and ready to receive a command as a
virtual COM port.
(2) Oscillation mode This mode performs communications with the tags.
When using FIFO access mode, oscillation mode continues until a STOP
command or STOP signal is input.
(3) Standby mode In this mode, the COM port is closed as a virtual COM port.
Note As the first step, open the COM port so that the RFID unit will shift its mode from “Standby
mode” to the “Command waiting mode”.

3-2-1-1 I-CODE1 Chip (Philips IC product name : SL1 ICS30 01, SL ICS31 01)
1) Memory Map of I-CODE1
These specifications describe a Tag incorporating an IC chip I- CODE1 Label
IC from Philips, which is accessed by the system.
This chip consists of a 64-byte memory. The upper five blocks (Blocks 0 to 4)
of the memory are used as a system area having functions that do not relate to
user memory. OMRON offers special commands for accessing this area in
order to ensure the great ease of these functions by the user.
Refer to Command List for details. OMRON defines the blocks below Block 5
as the user memory area. Block 5 is page 00h, and the subsequent blocks are
allocated as shown below.
The memory is organized with four bytes as one page (4 bytes = 32 bits).
One page is the minimum unit that can be read from and written to the
memory.
The memory allocation described in this user's manual is in accordance with
OMRON's memory allocation scheme.

Special NoteBlock 4 can be used as part of the user memory when the Distinguished Tag
Read/Write function by family code (FC) or application ID (AI) is not used. If such use is
preferred, define this page as F Hex to use it as part of the user memory. In this case,
the user memory area becomes 12 pages long.

2) System Area of I-CODE1
The system area of I-CODE1 is mapped onto the memory. OMRON allocates
the system area to pages B Hex to F Hex.
(1) SNR（pages C Hex, B Hex）
SNR is a tag-specific code and has been written into the memory during the
chip production process.
The RFID Unit is shipped with this page write-access inhibited (refer to page D
Hex); there is no way of making this page rewritable by the user.
(2) Write-access conditions (page D Hex)
The pages are write-inhibited permanently if they are so indicated in the
memory map. The factory settings are as follow. If the two bits of a particular
page are 0.0, that page is write-protected.
