The V720-series Electromagnetic Inductive RFID System is ideal for the construction of highly
functional, long-distance wireless ID systems for material control and logistics.
V720S-BC5D4A (hereinafter called “Reader/Writer”) is the device to communicate with Tag
(manufactured by OMRON) of the V720-series that use two kinds of I-CODE chips manufactured by
Philips Semiconductor (Product name: SL1 ICS30 01, Common name: I.CODE1; and Product name:
SL2 ICS20, Common name: I.CODE2). The chip SL2 ICS 20 is fully conforming to ISO/EC15693.
The Reader/Writer can be connected to personal computers (PCs) and Programmable Logic Controllers
(PLCs) to process large amounts of data flexibly with simple commands.

■Highly Functional RFID System
In addition to 1-to-1 communication between a Tag and an
antenna, the RFID System operates in either multiple
simultaneous access mode, selective access mode, or FIFO
(first-in, first-out) read/write mode. In multiple simultaneous
access mode, if there is more than one Tag in the communications
area, the RFID System reads and writes data from and to all the
Tags at one time. In selective access mode, the user can specify the
Tags from and to which data is read and written. In FIFO
read/write mode, the RFID System reads and writes data to one
Tag after another as they come into the communications area.
■Support of off-line EAS Mode
The Reader/Writer can operate in EAS mode (see 3-7 in Section 3)
as a standalone device, with no need to connect with the host.
■I/O function
By issuing commands from the host, the user can operate three
input points and four output points.
■Protection Construction
The protection construction IP60 has been achieved in the
Reader/Writer.

Note:
In the configuration, where multiple Reader/Writers are connected via an RS-485 interface, the commands in a
Communication Mode by which responses are returned at the Tag’s entry into the communication area, such as
those in the Auto or Repeat Modes, cannot be executed simultaneously. The responses from the Reader/Writer will
collide, preventing the host from receiving them normally. Such commands must be executed from the Polling
Command, or by the time-shared processing performed by the host.

2-4-2 I.CODE1Chip (Philips Semiconductor IC, product name: SL1 ICS30 01, SL ICS31 01)
These specifications describe a Tag incorporating an IC chip I- CODE1
Label IC (product name: SL1 ICS30 01) 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 5-5 "System commands" for details. OMRON defines the
blocks below Block 5 as the user memory area. Block 5 is page 00, 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 these specifications is in
accordance with OMRON's memory allocation scheme.

3-1-2 Online Mode /Offline Mode
The Reader/Writer operates in either Online Mode, in which commands
are given by the host, or in Offline Mode, in which the EAS function (refer
to SECTION 3-7) performs the configuration, when the host is
disconnected and the communication test between the antenna, the
Reader/Writer and the Tags.
The factory default is set to Offline mode. To change the mode to the
Online Mode, connect the host and execute the Stop Command (ST). To
always start the Reader/Writer in the Online Mode, the default mode is
disabled using the Offline Mode Setting Command (FL).
When the Reader/Writer is turned on in Online Mode, it remains in a
stand-by state, until commands from the host are received.
In the Offline Mode, the Reader/Writer starts detecting the EAS-enabled
Tags (the EAS function mounted on the Tags is not disabled) from the
moment it is turned on in this mode the COMM LED remains flashing. At
the entrance of an EAS-enabled Tag into the antenna communication
area, the external output turns ON for the specified time. The OUT1 LED
light indicates normal communication between the Reader/Writer and
the Tags .
To check the communication status in the Offline Mode, the EAS on the
Tags must be enabled in advance.
Note:
●If the type of Tags used and the chip operating mode setting do not match, the Reader/Writer will not
respond to the Tags. The No Tag Error （code: 72） results.
●Specifying the commands or functions unavailable in the specified Chip Operation Mode will result in
a Format Error (code: 14).
●The communication test in Offline Mode is performed with the EAS on the Tags enabled. The
communication by the EAS function takes longer compared to Read/Write operations performed by
other functions. The communication distance in the Online Mode should be checked using the actual
commands.
3-2
3-2 Communication Modes
3-2
This Reader/Writer has five communication modes to be selected by each
command corresponding to the number and/or state of Tags in the
communication area.
Each mode is activated by specifying the communication in the command
data.
3-2-1 Single Access
Single Access is used to read data from or write data on the only Tag that
exists in the Antenna Communication Area. The execution timing can be
selected from Trigger, which executes immediately, Auto, which waits for
the Tag to enter the communication area and executes, or Repeat, which
repeats the execution for the Tag in the communication area.
Be sure to have only one Tag in the communication area. Multiple Tags in
the Antenna Communication Area prevents the antenna from
communicating normally.
：In the I.CODE1 Mode, the Tag is processed only once at the entry
into the communication area. It can be reprocessed once it is
outside the area again.
3-2-2 FIFO Access
FIFO Access is used to read data from or write data on the Tags
sequentially in the same order they entered the antenna communication
area. (FIFO First In First Out).
The execution timing can be selected from Trigger, which executes
immediately, Auto, which waits for the Tags to enter the communication
area and executes, or Repeat, which continues to wait for the Tags to
enter the communication area.
Since every Tag finished with communications is set to access prohibit,
communications will be possible if only one Tag newly arrives in the
communication area of the Antenna where more than one Tag exists.
An error results, however, if two or more Tags arrive in the
communications area simultaneously. Once an access-prohibited Tag
leaves the communications area, access to the Tag is enabled again.
3-3
3-2 Communication Modes
3-2-3 Multiple Access
3-2
Multiple Access is used to read data from or write data on the Multiple
Tags in the Antenna Communication area simultaneously.
Communications with Multiple Tags in the communications area is
available. (This function is also called 1:N Access or Multiple Tag
Simultaneous Access). The execution timing can be selected from Trigger,
which executes immediately, or Repeat, which continues to wait for the
Tags to enter the communication area.
In I.CODE1 Mode, specify the appropriate tag-number code in command
data according to the number of Tags that exist in the communication
area (refer to SECTION 5-2-5).
The Duplicate Communication Protecting Function is useful for unstable
Tags in the Antenna Communication Area (refer to SECTION 3-8 for
details).
3-2-4 Selective Access
Selective Access is used to read or write data on specified Tags among the
multiple Tags in the communication area.
In ISO Mode, communication with specific Tags is achieved by first
reading the Tag UIDs (unique codes) in Multiple Access Mode and then by
specifying them. It is recommended that the UID/SNR addition option of
the Command Processing Procedure Setting should be used. It is
especially convenient since data readouts and UID acquisitions are
performed by a single command.
In I.CODE1 Mode, the Tag Detection Command that assigns numbers to
the Tags in the communication area in Multi Access Mode is performed
first, and then the Tag Designation Command that specifies the assigned
numbers is performed to launch the communication with the specific
Tags.
3-4
3-2 Communication Modes
3-2
3-2-5 Fast Read Access: I.CODE1 Mode Only
The Fast Read Access speeds up the data readout in I.CODE1 Mode. The
execution timing can be selected from Trigger, which executes
immediately, Auto, which waits for the Tag to enter the communication
area and executes, or Repeat, which repeats the execution for the Tag in
the communication area.
The function operates the same way as in Single Access mode when the
Tag number code is set to 0; in other cases it is the same as in Multiple
Access Mode.
[When the Tag number code is set to 0 (Single Access Mode)]
By selecting the Trigger or Auto execution timing, the function executes
the same operation as that in normal single access mode but in a shorter
period of time.
When the Repeat execution timing is selected, the function continuously
returns data while the Tags are present in the communication area, this
is useful in confirming the communication area.
[When the Tag number code is set to those other than 0 (Multiple Access
Mode)]
The only execution timing available is Repeat, since the function employs
a simple version of the communication sequence, some Tag data may be
unreadable under the condition where the responses from the Tags collide
frequently. In addition, the function processes and responds to the same
Tags repeatedly while they are present in the communication area.
This function should be used when there is a low number of Tags in the
communication area. When there are a greater number of Tags, the
Multiple Access Mode should be used. The Duplicate Communication
Protecting Function is useful to avoid multiple responses returned to the
same Tag. (Refer to SECTION 3-8).
Note:
●For the I.CODE1 Communication Modes used under the conditions, where Multiple Tags exit in the Antenna
Communication Area (Multiple Access, Selective Access, or Fast Read Modes), the Tag Number Code must be
specified. The maximum number of Tags allowed in the communications area is set previously. (Refer to
SECTION 5-2-5 for details).
3-5
3-3 Memory Check Function I.CODE1 Mode Only
3-3
By adding a check code to the data in the Tag, you can detect data errors
due to the Tag memory (EEPROM) being overwritten, service life, and
unforeseen factors.
The check code uses the CRC code of the generating polynomial X16 + X12
+ X5 + 1.
A memory check is performed using the Memory Check Command (MC),
which writes the check code, and the Memory Calculation Command
(MK), which verifies the check code. In the check block defined using the
header page and the number of pages, the target calculation area is the
area except for the last page of the block, and the last page is the check
code area. The check code uses two bytes in the check code area.
When a check code write command is sent, the CRC code for the data in
the target calculation area is calculated, and written to the check code
area. When the data verification command is sent, the CRC code for the
data in the target calculation area is calculated, and compared with the
data in the check code area. If these match, the number 75 is returned in
the response code to show that the data is normal. If they do not match,
the number 76 is returned to show that there is a data error.
Example: Memory check is performed when check block header page is 00
and the number of check blocks is 0B.

3-4 Lock Function
3-4
The Lock function protects data from being erased due to unintentional
overwriting on the fixed data in the Tags.
■ Lock setting in ISO mode
For the lock setting in ISO mode, you can write-protect any given areas by
the page of Tag memory.
If you execute Write command on a write-protect page, a write processing
error (code:79) will occur. You can make the lock setting by executing the
Lock command (LK) that enables access to the lock setting area.
For the details, see 5-4-7 “Lock Setting: ISO Mode.”
■ Lock setting in I.CODE1 mode
There is a lock setting area in the system area of I.CODE1 chip, and you
can write-protect any given areas by page.
If you execute Write command on the write-protect page, the write
processing error (code:71) will occur.
The lock setting consists of 12 bits of data in total, giving one bit to each
page. Lock setting can be made by using the Lock command (LK).
For the details, see 5-5-9 “Lock Setting: I.CODE1 Mode.”

3-5 Discriminating Access to Tag Function
3-5
The ID codes set in the Tags are utilized in identifying the target chips in
the antenna’s application fields. Responses are returned only when the ID
code in the command from the antenna and the ID code on the Tag are
matched.
The factory default of the Reader/Writer ID codes are all set to 00h, which
means communications are available regardless of ID codes on the Tags.
■I.CODE1 mode
The I.CODE1 chip has two kinds of one-byte ID codes called the Family
Code and Application ID. The Tag ID code can be set/modified by the
Write Command (WT) with the Family Code/Application ID area (FF
page) specified.
The ID codes for the Reader/Writer can be set/modified by the
Reader/Writer Family Code Setting (FC)/Reader/Writer Application ID

This setting enables communications with Tag A and B as their
family codes match. Communication with Tag C is not possible. This
identification code has nothing to do with identifying Tags as the
application ID is “00h.”
Reader/writer setting (3)
The communication with Tag “A” is possible as the family code and
application ID match. The communication with Tag B and C are not
possible.
■ISO Mode
Both the I.CODE SLI and ISO/IEC Chips have a one-byte ID code called
AFI (Address Family Identifier). To use this function, the AFI’s must be
set for the Reader/Writer and Tags, and the function must be enabled on
the Reader/Writer as well. The Tag ID codes are set/modified using the
System Write (SW) Command. The ID codes for the Reader/Writer are set
by the Reader/Writer AFI Enable/Disable Changeover (AE) Command or
the Reader/Writer AFI Value Setting (AF) Command.

3-6 External I/O Function
3-6
The I/O connector has three external input ports and four external output
ports to which such devices as sensors or actuators are connected to build
a more efficient system.
The external output may be dedicated to the antenna control, depending
on the Reader/Writer settings.
3-6-1 External Input
[Online Mode]
The status can be obtained by the I/O Control Command (CC). Sequenced
operations such as those for starting and terminating the communication
with Tags by external triggers are available.
[Offline Mode]
Not available. The I/O Control Command (CC) is rejected. To perform the
function, the mode must be switched to the Online Mode by the Stop
Command (ST).
3-6-2 External Output
[Online Mode]
The output status can be modified or read-out by the I/O Control
Command (CC.) Read-out data can be evaluated by the host and output
as a control signal for Lamps or sounds.
When the I/O Automatic Changeover Setting is enabled, the external
outputs 3 (OUT3) and 4 (OUT4) are dedicated to the antenna control and
thus unmodifiable. However, the output status can be read-out.
[Offline Mode]
The external output is dedicated to the control from the Reader/Writer in
this mode. Modification/Reading out of the output status by the I/O
Control Command (CC) is unavailable.
The external output 1 (OUT1) is turned ON for a specified period of time
(modifiable) when Tags with the uncanceled EAS is detected. The
external outputs 3 (OUT3) and 4 (OUT4) are dedicated to antenna control
when the I/O Automatic Changeover setting is enabled.
3-9
3-7 EAS Function
3-7
The Reader/Writer supports the EAS (Electronic Article Surveillance)
system applied for anti-theft and other devices. The Reader/Writer
identifies the unique data string returned by the EAS-bit enabled Tags
and detects the existence of the Tags in the communication area. Multiple
EAS-bit enabled Tags that exist simultaneously can also be detected. The
Reader/Writer stops detecting the Tags by disabling the EAS bit on the
Tags. This is useful in preventing unauthorized removal of properties or
giving caution.
The function operates in either Online Mode, where the function is
executed by the commands issued by the connected host, or Offline Mode
where the function is executed by the Reader/Writer alone.
[Offline Mode]
In the Offline Mode, the EAS-bit enabled (non-disabled) Tags are
continuously detected. When the EAS-bit enabled Tags enter the
Antenna Communication Area and their EAS-response concordance rate
exceeds the specified value (=EAS threshold), the external output 1
(OUT1) will turn ON for the specified time. The operation state is visibly
identified by the OUT1 LED light. The EAS threshold and external
output time are specified by the Offline Mode Setting (FL) Command.
●EAS threshold
The Tags return 256-bit fixed data. The concordance rate at which the
Tag is recognized as one with non-disabled EAS (EAS-bit disable
processing is not performed) is specified by a percentage. The smaller the
concordance rate, the more lax the criteria becomes. The initial threshold
is 75%.
●The ON-time of the external output 1 (OUT1)
The ON-time is specified according to the output time of the lamp or
buzzer. The initial output time is 500ms.
[Online Mode]
The EAS Check (EA) Command is executed from the host. (Refer to
SECTION 5-5-10). The EAS-response concordance rate is returned, which
is compared to the threshold in the host and evaluated for the existence of
the EAS-enabled Tags.
■EAS Setting for the Tag
The EAS on the Tag is enabled by a specific command that enables
EAS-bit. For the ISO/IEC chip (I.CODE SLI chip), it is done by the
System Write (SW) Command and for I.CODE1 chip, it is done by the
EAS Setting (ES) Command.
3-10
3-8 Duplicate Communication Protecting Function
3-8
The Duplicate Communication Protecting Function prevents the command that
processes multiple Tags serially from performing multiple Read/Write processing
for each Tag. This function controls the command so that it performs the
processing only once per Tag and returns a single response, even in situations
where a Tag is recognized more than once as shown below. The processing load is
reduced because the response receiving or duplication check by the host is
unnecessary. The communication performance speed is also improved since
unnecessary processing is eliminated in the following:
1. The situation where the Tag enters the Antenna Communication Area several
times due to its vibration, irregular operation, or stop on the boundary, or because
the Tag is in the antenna’s side lobe area.
2. The situation where the Tag is stopped in the boundary zone or enters the
Antenna Communication Area several times because of the moved antenna.
3. The situation where the Tag passes an antenna with a discontinuous
communication area such as the gate antenna.
The enabled function is activated when the commands using the following
communication modes are executed:
・FIFO Repeat Mode (FR)
・Multiple Trigger Mode (MT)
・Multiple Repeat Mode (MR, UR[I.CODE1 Only]*)
When the function is enabled, the unique number (UID/SNR) given to the
processed Tag is recorded in the table of the processed Tags after the command has
been executed. When a new Tag is detected and its UID/SNR is obtained, the
system refers to the table and processes the Tag only when the UID/SNR is not
found in the table. After the Tag has been processed normally, the system records
the UID/SNR in the table. The table is initialized at the start of command.
* As to UR, the page on which the processing is started must be FB, and the pages
must be 2 and more.
The function is set by the Duplicate Communication Protecting Function Setting
(MX) Command (disabled by factory default.) To enable the function, specify the
maximum number of UID/SNRs recorded in the table of the processed Tags. The
number of tables can be selected from 1, 4, 8, 16, 64, 128, or 256. Usually, the
closest number above the maximum number of Tags that can co-exist in the
communication area of the antenna being used is specified.
Example) When the maximum number of the co-existing Tags are 6: The number
of tables = 8
The table of the processed Tags:
1: Tag０
2: Tag１
3: Tag２
4: Tag３
5: (Vacant)
6: (Vacant)
7: (Vacant)
8: (Vacant)
In this case, Tag 0 is not processed for re-entry in the communication area. When
the Tag 4 enters the area it is processed and recorded in row 5: of the table.

4-1
The V720-series RFID system has two operation modes: Offline Mode and Online Mode. The functions
and control methods by the host vary, depending on the Operation Mode. One of the two modes must be
selected at system setup.
4-1-1 Offline Mode
In the Offline Mode, the EAS-enabled Tags (the EAS function mounted on the Tags is not
disabled) are always detected (1). When the EAS-enabled Tags enter the antenna
communication area, the output results (OUT1) turns ON for the specified time (2). The control
from the host is unnecessary. The PCs used for setup are connected as needed when the
operating conditions must be specified. Some outputs are exclusively used for antenna control,
depending on the settings.

●Command Standby State
The Command Standby State is where the Reader/Writer is not processing but can accept any
command other than AK or NK, which are used for ACK/NACK control. When the Reader/Writer
accepts a command, it enters the command processing state.
●Command Processing State
When a command is accepted, other commands are ignored until the accepted command has been
processed. However, the Stop (ST) and Reset (XZ) Commands are always accepted. When a command
that performs continuous processing is executed, the processing state continues until completed or
stopped.
The COMM LED is lit (flashed) while communication with the Tags is in progress.
The Reader/Writer enters a special command processing state in the following situations, although it is
not actually communicating with the Tags. The COMM LED is not lit in these cases.
・After the commands have been executed in FIFO trigger or FIFO auto mode
FIFO continuation state where the antenna oscillates continuously: Only the FIFO access
commands are accepted.
・After the Tag Detection Command has been executed (I.CODE1 Mode only).）
Selective state where the simplified numbers of Tags are stored, only the Tag specification
commands are accepted.

Offline Mode is set by the Offline Mode Setting Command (FL). The default mode is
set for Offline Mode.
By setting the Test Mode, the communications between the Antenna and Tag can be
tested without connecting the host. You can exit the Offline Mode by connecting to
the host and sending a Stop Command (ST)
By using Test Commands(TS), the communications between the Reader/Writer and
host can be tested. This test allows the checking of the cable connection and the
processing operation of communications before the trial operation of the whole
system. It is recommended that RS-232C be connected to COM2 where the
communication condition is fixed.
・Prepare a simple communications program on the host and transmit Test
Commands.
・If the communications line is normal, the Reader/Writer returns the data received.
Check the operation on the real system using the setting commands under the
actual operating conditions defined by the system design. When using COM1, the
RS-232C cable connection must be modified.
:Conduct the test of the final installation positions of both the antenna and Tag after the lapse of standby
time (15 minutes). Standby time means the time that elapses after turning the power on to getting the
product ready for stable communications

4-3 Reader/Writer Setting
4-3
The Reader/Writer has been designed for the user to make all the settings
by issuing commands from the host. The user can use either the COM1 or
COM2 port to make settings. However, we recommend use of the COM2
port because its communications settings have been fixed at factory to
survive a power reset.
In order to fix the information set for the Reader/Writer to survive a
power reset, it is necessary for the user to execute the setting write
command (EW) (refer to 10) in 5-７-14 of Section 5). (This does not apply
to the communications settings for the COM2 port).

Precautions on setting modifications
●The execution of the setting commands only modifies the S-RAM (volatile memory) on the Reader/Writer. The
modifications are not reflected immediately; they are reflected only after the Reset Command (XZ) has been
executed.
●To apply the modified settings at the next startup, fix the settings and reset the power supply. If the settings are
not fixed, the modifications will be reset to the original status after the power supply reset. This does not apply to
the communication settings for COM2.
●If Reset Command (XZ) is executed without fixing the settings, the settings are reset to original status after the
power supply reset.
●The default mode is Offline mode. To change the settings, the mode must be switched to Online mode. Connect the
host and execute Stop Command (ST.)

4-4 Installation Environment
4-4
The V720S-BC5D4 Reader/Writer is a highly reliable control device
withstanding tough environments. In order to ensure the full, reliable
performance of the RFID system, however, observe the following.
4-4-1 Installation
Do not install the Controller under the following conditions.
•
The ambient temperature is not within a range between -10℃ and
50 ℃ or there are radical temperature changes resulting in
condensation.
•
The humidity is not within a range between 35% and 85%.
•
There is corrosive gas, flammable gas, dust, salt, or metal powder.
•
The Reader/Writer is affected by direct vibration or shock.
•
The Reader/Writer is exposed to direct sunlight.
•
Oil, or chemical is sprayed onto the Controller.
•
Do not install the Reader/Writer close to heaters, transformers, or
resistors that radiate excessive heat.
•
If power lines or high-tension lines with large currents are located
close to the Reader/Writer, be sure to test the Reader/Writer
carefully and make sure that wires connected to the Reader/Writer
are not affected by the noise of power lines or high-tension lines.
Note
●Be sure to abide by the above before installing the Reader/Writer and carefully test the Reader/Writer.
●Be sure to wire antenna cables separately from other cables. For the antenna cable, be sure to use V720-A41
3.35M or V720-A41 10.33M that is specially designed for this product. Using any other cable may affect adversely
the communications performance, waterproof performance, etc.
● For wire power and I/O cables as well, wire them separately wherever possible in order to avoid malfunctions.
Caution
Ensure that a solid (Class D) grounding is established for the “GR” on the Reader/Writer power connector.
4-10
4-5 Mounting Method
4-5
The Reader/Writer must be mounted using a mounting plate. When
mounting, be sure to secure it onto the mounting plate with M6 screws,
spring washers and flat washers.
Do not apply organic solvent, e.g., screw lock solvent, to the screws to
secure the Reader/Writer. If you do, the Reader/Writer body and the
mounting plate may be damaged.

How to attach ferrite core:
Open the ferrite core. Put the cable
inside and roll one time as shown in
the figure. Close the core in the
direction of the arrow and make
sure it locked. Set the core near the
DC power supply side.
Note
● Use 24 VDC to supply power to the Reader/Writer. When you use the recommended power supply, S82K-03024,
and a cable with a thickness of AWG16, the cable can be extended to 7 meters at maximum. If a longer power wire
is desirable, use a power supply with remote sensing function.
● The maximum power consumption of the Reader/Writer is 25 W. An inrush current of approximately 30 A at 24
VDC, however, flows when the Reader/Writer is turned ON. Take this into consideration when preparing the
power supply.
● Provide a power wire with a thickness of AWG16 in order to prevent the dropping of voltage. It is recommended
that twisted-pair wire be used for the power line. The thickness of AWG16 is the maximum wire diameter that
can be used with the power connector of the Reader/Writer.
● Use Class D grounding (previous Class 3 grounding) for the Reader/Writer for improved noise
resistance.
● Use the ferrite core enclosed to the Reader/ Writer for the 100VAC side of the recommended compact
DC power supply S82K-03024.
WARNING
● Be sure to connect to a power supply with a maximum power supply capacity of 24V 4.2A (100 W) or less.
In case a short-circuit failure should occur within the Reader/Writer, a burnout in the power cable may result.

Leave the pin for RS-232 unconnected.
Be sure to use a twisted-pair wire for the signal line.
Be sure to use a wire with a thickness of AWG20 for the signal line.
When you use a shielded cable, be sure to ground on the host side.
Make sure that the total cable length for 1-to-1 and 1-to-N connection is not longer than 300 m.
Note
When you connect more than one Reader/Writer, give special attention to communications timing
between Reader/Writers. To ensure proper timing, you will need to perform both theoretical calculation
of timing and verification of communications on real machines.
1)
The Reader/Writers cannot operate simultaneously except through polling-related commands.
This means that, even when you connect more than one Reader/Writer, only one Reader/Writer
can communicate with the host at a time.
Multiple Reader/Writers can access the host only in a time-phased manner.
2)
When you use an Auto command, the Reader/Writer will not return a response but continue to
wait if there are no Tags in the communications area. In this state, if you send a command to
another Reader/Writer, no command will be accepted until a response is returned. To avoid this,
you must abort the Auto command using the STOP command before sending any command.
3)
Polling-related commands do not support any commands but Auto commands. These commands
are not available in Multiple Access Mode (which permits access to multiple Tags) to avoid
processing complexities.

5-1 Control by Commands
5-1
5-1-1 Control by Commands
The Reader/Writer operation is controlled by the commands from the connected host. The result of the
command execution is returned as a response.
In Online Mode, all the operations, such as Tag-data Reading/Writing, Tag-function setting, operating
condition setting, or Reader/Writer function control, are controlled by the commands.
In Offline Mode, the Reader/Writer functions controlled by the commands are restricted to those
controlled by Stop and Reset commands. The operating conditions for Offline Mode are set in Online Mode.

5-1-2 Command-Response Flow
In Online Mode, the host sends an instruction command and the Reader/Writer returns the result as a
response. The command-response flows vary, depending on the types of commands and specified
communications, as shown below.
1-to-1 Response
One response is returned per command for Single Trigger (ST), Single Auto (SA), FIFO Trigger (FT), FIFO
Auto (FA), UID Select (SL), or Tag Designation is specified for the command that performs the
communication with the Tag, or when a command that does not perform the communication with the Tag
is specified.

5-1 Control by Commands
5-1
5-1-3 ACK/NACK Control
When using ACK/NACK control, if the host does not receive a normal response, the Reader/Writer will
resend the response by either (1) when the host sends a NACK command to the Reader/Writer or (2) when
there is no response within a set period of time. Consequently, a response can be received without
communicating with a Tag again. The host checks that responses have been received normally using the
ACK/NACK commands, so response data can be communicated dependably.
■Using ACK/NACK Control
If the host receives a normal response, it sends an ACK command to the Reader/Writer. The
Reader/Writer judges that the host has received a normal response, and enters a command-waiting state.
If, after the Reader/Writer has sent the response, an ACK is not received normally within the time set
using the time out setting, or a NACK is received, the Retry Flag is set and the last response is sent again.
The maximum number of response retries that can be made is nine.

5-2 Control Procedures for Each Communication
5-2
The operating sequences including the communication with the Tag or timing for returning the response
vary, depending on the communication mode. The communication mode is set by specifying the
communication mode in the command data. The access and mode specified as the communication settings
must be those specifiable for each Tag status in the specified antenna’s communication area or the
connection topology with the host. This section describes these access and mode settings.
5-2-1 Single Access
In single access, a single Tag can exist in the communications area. The presence of two or more Tags in
the communications area causes a communications error.
5-2-1-1 Single Trigger mode
Single Trigger mode is used when a single Tag is present in a resting condition in the antenna
communication area. If the Tag does not exist in the antenna communication area, No Tag
Error is returned.

(If the function is executed in I.CODE1 mode, the Reader/Writer will perform the process only once at the Tag’s
entry to the communication area and return a response. Multiple Tags in the communication area may result in a
response with abnormal read data).

5-2-1-4 Polling Auto Read
If an Auto command is used when a single host controls more than one Reader/Writer, the
communications path between the host and one of the Reader/Writers to which the command is
sent becomes busy, disabling the host to control other Reader/Writers. On the other hand,
when a Polling Auto command is sent instead, the Reader/Writer returns a response according
to the request from the host. The communications line with the host will not remain busy,
allowing the host to send a command to other Reader/Writers. When Polling Auto command is
executing, the only commands accepted and executed are Polling Check (PC), Polling End (PE),
Reset Command (XZ), and Stop Command (ST). An example of Polling Auto Command
executed for two Reader/Writer devices are shown below.

5-2 Control Procedures for Each Communication
5-2
5-2-2 FIFO Access
In FIFO (first-in, first-out) access, communications with Tags entering the communications area one after
another are carried out in sequence. Once communications with Tags are completed, access to them is
prohibited. Consequently, even if Tags with which communications are already completed exist in the
communications area, a newly entering Tag can be accessed. Simultaneous entering of two or more Tags
causes a communications error. Once an access-prohibited Tag leaves the communications area, access to
the Tag is enabled again.
5-2-2-1 FIFO Trigger Mode
FIFO Trigger Mode is used for communications when the Tag is present in a resting condition
in the antenna communication area. The Reader/Writer prohibits access to the Tag after the
communication has been completed, and keeps the antenna oscillated to maintain the FIFO
access. Under such conditions, the Reader/Writer can issue another FIFO command and
communicate with the next Tag that enteres the communication area, where the previous Tag
with which the communication has been completed is still present. (The commands other than
FIFO Access are rejected).
When there are no accessible Tags in the antenna communication area, the No Tag Error is
returned.To exit the FIFO state, execute Stop Command (ST).

5-2-2-3 FIFO Repeat Mode
The Reader/Writer waits until the Tag has entered the antenna communication area and starts
communicating. It communicates with the Tags serially as they enter the antenna
communication area, and returns the responses. When the communication has been completed,
the Reader/Writer makes the Tag inaccessible, so that it can communicate with the next Tag
that entered the area although the Tags with which the Reader/Writer has completed the
communication are still present in the same area.
This state continues until the communication has been terminated by Stop Command (ST), or
Reset Command (XZ), and other commands are rejected.

When the Tag is on the boundary of the communication area or enters the communication area
more than once because of swing, the Tag may be processed more than once, or some Tags may
not be processed.
In this case, enable the Duplicate Communication Protecting Function (Table number = 1). The
function will prevent the Reader/Writer from communicating with the Tags already
communicated with, and allows proper and sequential Tag processing.［Software Ver 1.20 and
higher only］
Note
To send another command from Repeat Mode, be sure to use either the stop command or reset command, and
make sure that the Reader/Writer has finished processing commands and is in command waiting status before
sending the new command.

5-2-3 Multiple Access
In Multiple Access, the Reader/Writer can communicate with all of the multiple Tags present
in the antenna communication area. In I.CODE1 Mode, the Tag code corresponding to the
number of Tags present in the communication area must be specified. For the Tag number
specifications, refer to SECTION 5-2-5.
When the Tag is on the boundary of the communication area or enters the communication area
more than once because of swing, the normal operation may be interrupted because the Tags
are processed more than once. In this case, it is recommended that UID/SNR addition setting
be enabled to evaluate the Tags on the host side. In addition, one processing per Tag is
available by enabling the Duplicate Communication Protecting Function. For Duplicate
Communication Protecting Function,, refer to SECTION 3-8.

and returns the results of the communications with each tag as a response. At the completion of
communicating with all the Tags, it returns Detection End Response (Response Code: 00) once.
The number of Tags with which the communication has been normally completed is added to Detection

In ISO Mode, if the communication with the detected Tag failed, the Reader/Writer returns an error
response immediately and moves on to process another Tag. At the completion of communicating with all
the detected Tags, it returns the Detection End Response and terminates the command processing.
In I.CODE1 Mode, the Response Code is set to 00 only after the communications with all the detected Tags
have been completed successfully. When the number of Tags detected exceeds the number specified by the
Tag code in command data, the Response Code is replaced with a warning code (Code: 0□), (Refer to
SECTION
5-3-7).
If data writing process in even one Tag has failed, the Reader/Writer returns to Write Process Error
(Response code: 71), and terminates the command processing.
Note:
In processing Multi-Trigger Command, some Tags may not be processed due to their conditions (including the
distances between the antenna and Tag, or those between the Tag and another Tag). The operating system must
be configured to check the number of processed Tags based on the number of returned responses or normally
processed Tags, and match them against the actual number of the Tags.

5-2 Control Procedures for Each Communication

5-2-4 Selective Access
Selective Access is a function to communicate with the specified Tags among multiple Tags in
the antenna communication area. The processes vary depending on the Reader/Writer’s mode.
5-2-4-1 ISO Mode
First, the Reader/Writer reads out the UID of the Tag in the communication area using Read
Command (in multiple processing modes). The UID is readable when UID/SNR addition
setting option is enabled in advance using the respective command (SN). When the UID is
already identified, the execution of Read Command can be skipped. Then, the Reader/Writer
communicates with the specified Tag based on the obtained UID.
(1) The Reader/Writer reads the UID of the Tag using Read Command.
It reads out UID data of the Tag by executing a Multiple Trigger Mode command with its
UID/SNR addition setting enabled.
(2) The Reader/Writer communicates with the specified Tag (No. 2 in the figure below) by
specifying the UID obtained in 1 using UID Select Read/Write command.
The ReaderWriter communicates with the Tag specified by the UID. For UID Select
Command, specify SL for the communication, and specify the UID of the communication
target Tag in the UID area in hex number, 123.
Note:
Some Tags detected by UID read (Tag detection) may not be communicated with Selective Access mode using UID
Select (Tag designation) command, depending on the Tag conditions (the distances between the antenna and tag,
or those between the Tag and another Tag). This is especially true when the Tag exists in the boundary area of
the communication area. The operating system must be configured to check the number of detected Tags against
the number of Tags the Reader/Writer communicated with (or the number of the actual Tags).

5-2-4-2 I.CODE1Moed
After allocating the Temporary numbers to the Tags in the communication area using Tag
Detection Command, the Reader/Writer communicates with the Tags based on the allocated
numbers. The Tag code must be specified as command data according to the numbers of the
Tags present in the communication area. For Tag number specifications, refer to SECTION 52-5.
1. Numbers are allocated to the Tags by Tag Detection Command.
Tag Detection Command, the state enters the Select State, where the mapping of the
Tags in the antenna communication area and their Temporary numbers are stored. In
Select State, all the commands are rejected except the Tag Designation Command. The
Select State is valid until Stop Command (ST) has been executed.
2. After allocating the numbers to the Tags, the Reader/Writer communicates with the
specified Tag (No.2 in the figure below) using Tag Designation Command.
The ReaderWriter communicates with the Tag specified by the Temporary number. It can
communicate with the Tags repeatedly in the Select State.
Tag Detection Command/Tag Designation Command
For Tag Detection Command, specify LT as the communication method of the command. For Tag Designation
Command, specify 00 to 7F as the communication method of the command. (To specify the Tag with Temporary
number 1, specify 01).

5-2-5 Specifying a Tag Code: I.CODE1 Mode
The timeslot setting is the setting in the command frame when communicating with multiple Tags
simultaneously using Multi-system commands. This setting must be set according to the number of Tags
with which to communicate simultaneously. Refer to the table below for the relationship between the
number of Tags and this setting.
Specifying a Tag
Code
Max. No. of Tags with which simultaneous
communication is possible
∼2
∼4
∼8
∼16
∼32
∼64
∼128
Example: If the number of Tags is seven, select Tag Number setting 3.
Note:
● For the Multi Trigger(MT) and the Multi Read(MR), if more Tags than have been set using the timeslot setting
enter the communications range, a "70" error (warning) may occur. (e.g., When the timeslot setting is "2" and
there are five Tags in the communications area.)
●For the Special Read (refer to 5-2-1-6) command, the anti-collision process is not performed. Therefore, read
data will be returned even If there are more Tags than the timeslot setting in the communications area.If a
collision occurs, such data will not be returned.
● The higher the timeslot setting is, the longer the communications time is required. Consequently, setting a
higher timeslot setting than required for the number of Tags in use unnecessarily lengthens communications
time, so select a suitable setting.

Description
A character of data occupies 1 byte (1 address) on a Tag as an
ASCII code or a JIS 8 code.
Control codes 02 (STX) and 03 (ETX) cannot be used.
A character is handled as hexadecimal data. Therefore, only
characters from 0 to F are accepted. Two characters of data
occupy 1 byte (1 address) on a Tag.
• Example of ASCII Representation
When writing "V720" to four bytes of memory of page 00 using ASCII data, the data will occupy the
Tag's memory as follows:
page 00h

• Example of Hexadecimal Representation
When writing "12345678" to four bytes of memory of page 01h using hexadecimal data, the data will
occupy the Tag's memory as follows:

Precautions on the communication-control software programming:
The BCC is a character representing the result of the horizontal parity check performed for data and ETX. The
BCC could be any code from 00h to FFh. (From 00h to 7Fh for 7-bit data). The communication control program
that runs on the host must be designed assuming the case where BCC is not defined as STX/ETX control
character or other characters.
* Some characters may not be available, depending on the program development environment or coding
method. Check the restrictions of the development environment of your choice.

I.CODE1 System Area
From Page FD to Page FF is a system area for write-protect and QUIET/EAS settings. Depending on the
content of write data, a Tag may become write-protected or inaccessible, so be sure to understand these
pages fully before use.
It is strongly recommended that data be re-written using a command dedicated to system area re-writing
rather than Write Command (Refer to SECTION 5-5). Re-writing data when the Tag is in an unstable
communication area may destroy data in the system area, interrupting the communication with the Tag.
Be sure to re-write data while the Tag is in a stable communication area.

repeatedly read while the Tag is in the communication area. (Refer to SECTION 3-2-5).
When UT or UA is specified as the communication method, the anti-collision processing (the operation to
prevent the collision of the response returned by the Tag), it is not performed even if a number other than
0 is specified as the Tag code. Therefore, if a collision (of the response) takes place, its Tag data cannot be

6-1 Error Types and Diagnostic Functions
6-1
The Reader/Writer performs a variety of self-diagnostic functions to reduce system downtime in case of an
error. The errors detected by the Reader/Writer are categorized into fatal errors and nonfatal errors.
Fatal Error
If the Reader/Writer main unit or hardware fails, the CPU operation is interrupted and the
ERROR LED is turned on or flashed.
●CPU error
Detects the CPU operation error using the watch dog timer (W.D.T.)
●Memory error
Checks if data is read from or written onto the internal memory normally when the power is on.
Nonfatal error
When an error occurs during communications between the Reader/Writer and the host, or the
antenna and Tag, the ERROR LED is turned on.
●Communication error
Checks for the errors in the communication processing sequence, frame, check code, and data at the execution of a command. The
error code corresponding to each error, is returned to the host as the response. (Error code:1□)
●Host communication error
Checks for the errors in the communication processing sequence of the command data, frame, check code, and data at the reception
of a command. The error code corresponding to each error is returned to the host as the response. (Error code:7□)
●System error
Checks that the command processing functions (EEPROM, communication circuit, etc.) are normal at the execution of a command.
The error code corresponding to each error is returned to the host as the response. If the error occurs repeatedly, the device needs
repair. (Error code:7C, 93)
●Set value error
Checks that set data concerning the operating environment on the EEPROM in the main unit is not corrupted.. Checks for errors at
power on, and if the error(s) are detected, operates in Online Mode with the factory default settings. The operating environment is
regained by setting the operating conditions once again.

7-1-3 Turn Around Time (TAT) Calculation Method
Calculation of TAT
TAT can be calculated by adding the host communications time to the
actual communications time. The host communications time varies
depending on the communications settings and the codes that you specify.
Example of calculation: when operating in Single Access Mode and Trigger
Mode to read 1 page (4 bytes) data
■Code-specified in ASCII:
The total number of characters is 29, i.e., 15 characters in the command
part and 14 characters in the response part. From this, the host
communications time would be 29 * 11 bits /38400(bps) * 1000 = 8.3 (ms).
The communications time would be14 ms for Fast Mode and 92.9 ms for
Standard Mode. TAT, therefore, would be 8.3 + 14 = 22.3 ms for Fast Mode
and 8.3 + 92.9 = 101.2 ms for Standard Mode.
■Code-specified in HEX:
The total number of characters is 33, i.e., 15 characters in the command
part and 18 characters in the response part. From this, the host
communications time would be 33 * 11 bits /38400(bps) * 1000 = 9.5 (ms).
The communications time would be14 ms for Fast Mode and 92.9 ms for
Standard Mode. TAT, therefore, would be 9.4 + 14 = 23.5 ms for Fast Mode
and 9.4 + 92.9 = 102.4 ms for Standard Mode.

7-2 Calculating the speed of the Tag
7-2
When communicating with a Tag in motion, select Auto or Repeat for the
communications method.
The maximum speed at which the Tag can travel can be obtained easily,
using the formula below.
Max. traveling speed =
D (travel distance in communications
area)
T (communications time)
x Safety factor (0.5)
Calculate D from the communications area drawing between the Antenna
and the Tag or from the actual measurement.
Communications
area
Direction of travel
：The formula above is for communications with one Tag. Be sure to check
the traveling speed of multiple Tags in advance.
Notes on the passing speed evaluation:
1） As a precaution to ensure minimal noise, the Reader/Writer performs retransmission tests in the event of a
communication error between the Tag and antenna. Since the transmission time is dependent on the noise
conditions in each environment, a transmission test using the actual device must be conducted in advance. The
calculation formula for the communication time does not assume retransmission.
2） The calculation formula above assumes the communication
