2. Preliminary check of installation site.
This device uses the frequency band 2450 MHz for the communi cation between an antenna and ta g. Some of radio equipment, su ch
as wireless LAN, cellular phon e, personal handyph one system and transceiv er, motor and switching power supply ma y generate a
radio wave (noise) which affects th e commun icat ion wi th a t ag. I f you must use this d evic e near s uch he ater, we would li ke to ask
you to check the influence in advance.
To minimize general influence of noise, follow the instr uctions below:

• Ground any metallic material located around this device according to Class D (Class III).

• Wire this device keeping away f rom high voltage and h eavy current.

3. Ambient environment and communication range

• The communication range varies depending on the installation site environment. This is because a metal material and the ground

reflect a radio wave, and wa ter and human bod y a bsorb it . Loc ate an anten na and ta g in th e commu ni cation range an d ch eck t he
radio wave environment in advance.

• The Read/Write antenna model V690-HMG01 has a co mmunication test command to check the radio wave en vironment at a

working site. (Refer to Section 3-5.)

4. Be sure to ground any ground terminal according to Class D (conventional Class III). Otherwise, performance may deteriorate.

• The antenna unit has achieved the transmi ssion speed 600 kbps and max imum communication r ange 5 m.

• The antenna uses ci rcularly polarized wave as radio wave. So, the ID tag facing the antenna can c ommunicate at any ro tating
angle on the medial axis. Th e maximum communication range varies depending on the tag angle.

• This antenna is a specified low-power radio station and, therefore, any radio station license is not required.

• The Multi Access funct i on which enables to access sev eral tags in the antenna communication area and FIFO (First-In First-Out)
function which enables to access the tags coming in the communication area sequentiall y one by one.

• By a command from a host dev ice, the comm un ic ati on 2 m Mode and 5 m Mode c an be switche d to eac h othe r and a r adio wave
channel can be swi tched at a working site. You can select the most suitab le commu nicatio n range at a worki ng site a nd prev ent
the mutual interference between antennas easily.

• The controller contains bo th of the RS-232C and RS-422A interfaces. So, it can connect to a general-purpose PC or programma­ble controller (PLC) which have RS-232C. Also, several antennas can be connected to one h ost device.

• A simplified communication test function, which can check the communication with a tag without a host device, and a communi­cation test, which can check a radio wave environment at a working site, are available.

Chapter 3 Functions

3-1 Single/FIFO/Multi Mode Access Function

You can use one of the three communication modes according to the number of tags in the communi cation area and the situation. The
communication mode can be specified in the communication designation in a command.

(1) Single mode

In the Single mode, the communication is made to one tag in the antenna commu­nication area. In the Sin gle m od e, o nly o ne ta g m u st be p laced in the a n tenn a co m­munication area. If two or more tags are in the antenna communication area, a
communication error occurs.

(2) FIFO mode (First-In First-Out)

The FIFO mode enables to access the t ags coming in the communication area
sequentially one by one. When the communication to one tag has been completed,
the tag is prohibited from communicating. So, even if there is any tag, which
ended the communication, in the antenna communication area, the communication
can be made to the next target tag. When the tag prohibited from communicating
has gone out of the antenn a communication area, such ta g can communicate again.

(3) Multi mode

When there are several tags in th e antenna communication area, the Multi mode
enables to access all those tag s. By using the Selective Access function, the com­munication can be made to a specified tag of those in the anten na communication
area.

Correct Usage

When you use the FIFO mode, only one tag mus t be plac ed in the a ntenna commu nicat ion area . If two or mo re tags are
in the antenna communi cation area, a c ommu nicati on error oc curs. Then , the comm unica tion ca nnot be recove red f rom
failure unless only one tag is in the antenna communication area.

3-1

3-2 Communication 2 m Mode/5 m Mode Switching

The communication 2 m mode and 5 m mode can be switched to each other by a command from a host device. Use either one depend­ing on a working site.
For the command, refer to Sections 5-9-2 and 5-9-3. The default value is the 2 m mode.
For the communication area of 2 m mode and 5 m mode, refer to Section 7-1.

3-2

3-3 Radio Wave Channel Switching

In this RFID system, a range from 2437.5 to 2462.5 MHz in the 2450 MHz frequency band can be divided into ten, and 10 channels (at

2.5-MHz intervals) are availa ble. Those channels can be sw itched by a command from a host device. Use them to prevent the mutual
interference between antennas or interference caused by any other devices.

For the command, refer to Sections 5-9-2 and 5-9-3. The default value is Channel 5 (2450 MHz).

Channel

2450 MHz frequency band

Correct Usage

Due to dispersion of frequency, the frequencies of adjacent channels may overlap each other. Do not assign consecu­tive numbe rs to the chann els of adjacent antennas.

3-3

3-4 Simplified Communication Test

You can check the communication between an antenna and tag using the antenna only without connecting to a host device.
In the simplified communication test, the antenna detects the tag at approximately every 2 seconds and, if the tag responds, it turns on
the indicator C.

(1) Turn off the power supply.
(2) Short-circuit the setting terminals "+P" and "-P".
(3) Turn on the power supply. Then, the setting mode is enabled. (Refer to Section 5-1.)
(4) The simplified communication test starts. As shown below, the indicator C (Radio wave emission) shows whether the communica-

tion to the tag is made successfully.

(5) When any command has been sent from a host device to the antenna, the com munication test stops.

3-5 Communication Test

Execute the communication test to check a radio wave environment at a working site.
Data (256 bytes) is communicated 256 times between the antenna and tag and the communication status is output. A total of 128 kbytes
of data is communicated in two ways. So, it takes a few seconds to execute thi s test. The communicatio n is not retried. Refer to Section
5-7-8.

(1) Create a com mu nication program at a host dev ic e.
(2) Enable the operation mode. (Disconnect the termin als "+P" and "-P" from each other. Refer to Section 5-1.)
(3) Turn on the power supply.
(4) Put the tag in front of the antenna.
(5) Send a commun i cation test command (Section 5-7-8) . If the ant enna is 00, the command is [STX]00 80T0SU[ETX].
(6) If the antenna respo nds to the host device, the communication between the host device and ant enna has been made successfully.
(7) In the re sponse [STX]800 0T0000256 [ETX], a radio wave en vironment val ue is between 0000 and 025 6. If the value i s

close to 0000, the communication to the tag is stable.

3-7 ID Tag Power-Saving Function

The tag has the two power-saving functions below.

♦♦♦♦ Function to prevent battery power loss due to radio wave emitted from any other radio

equipment (Enabled always)

If any radio equipment is located near a tag, the tag operates (ready to operate) because the tag’s receiving band is wide. As a result, the
tag battery may be consumed. (Refer to "Not es on Interference to Second-Generation L ow-P ower Data Communication System (Wire­less LAN), Cellular Phone, etc." at the beginning of this manual.)
To prevent this power loss, the tag has a function to enter a sleep state (refer to "Appendix 1 - Glossary") against a radio wave emitted
from any other radio equipment.

• The V690 antenna sends a wake instruction (refer to "Appendi x 1 - Glossary" ) at every 10 0 m sec aft er emittin g a radio wave and the
tag operates (ready to operate).

• When the tag receives a radio wave emitted from any other radio equipment, the tag may operate (ready to operate). However, unless
receiving a valid wake instruction, the tag returns to a sleep state in 2 seconds.

Wake instruction

Antenna radio wave emission

Even if there is no command from a host device, the antenna sends a wake
instruction at every 100 msec while emitting a radio wave.

3-7 ID Tag Power-Saving Functio n

♦♦♦♦ Function to prevent battery power loss due to neglect when tag works (Enabled always)

When you use the antenna with a repeat command (refer to (3) in Section 5-2-1), due to a trouble in a working site, the tag may be left
in front of the antenna which is emitting a radio wave, although the tag operates (ready to operate). Then, the tag battery is consumed.
To prevent this power loss, the tag has a function to enter a sleep state when a waiting time for sleep (refer to a chart below) has passed.

If the tag cannot receive a valid command within a waiting time for sleep after receiving a valid command, the tag enters a sleep state.
A default value of waiting time for sleep is 480 seconds (8 minutes). To change waiting time, specify "SLEP" as address in the Read/
Write command. (Refer to Sections 5-7-1 and 5-7-3 to 5-7-5.)

To recover the tag from the sleep state:

• Turn OFF the power supply transmission of the antenna and turn ON it again.

• Take the tag out of the communication area and pl ace it in the communication area again.

faces must face each other.

Antenna

Front face

(2) Antennas

Keep sufficient space between the antennas according to Section 7 -5. If sufficient space cannot be obtained:

• Assign the most different channel numbers to the radio channels of adjace nt antennas. (Refer to Section 3-3 .)

• Permit only one of antennas to transmit a radio wave so that those antennas do not transmit radio waves simultaneously.

(3) Tag rotating position to antenna

The antenna and tag use "circularly polarized wave" as radio wave to communicate with each other. So, the tag can commu nicate with
the antenna at any rotating angle.
The maximum communication range varies de pending on the rotating angle of the tag. Ref er to Section 7-3.

(4) Influence of external objects

• Radio wave absorbers: water, human body, water screen, water-absorptive material, etc.

A radio wave (microwave) penetrates anything (solid body and liqui d) oth er t han me tal, b ut it is a tten ua ted wh ile pe n etra ting . In p arti c­ular, water absorbs a radio wave extremely. When a radio wave penetrates the water, the radio wave is absorbed considerably. Also, the
radio wave is attenuated rema rkably i n a human body which co ntai ns much wate r. So, any solid bod y and li quid m ust no t exist between
the antenna and tag.

A general-purpose plastic plate with thickness of or glass plate a few millimeters does not absorb the radio wave, and the radio wave
attenuation is not a serious problem in this case. However, the radio wave attenuation varies depending on a type of material and/or
thickness of external objects which the radio wave penetrates. Execute the communication experiment in a working site in advance.
When the communication is performed through the plastic plate or glass plate which absorbs the radio wave so much, such plastic plate
or glass plate may be covered with water due to rain. The radio wave may be attenuat ed by this water screen and the communication
may fail. Execute the communication experiment in a working site in advance and take great care not to get out of the communication
range during an operation.

Dry wood and paper do not a tte nu a te the radio wave so much. However, wo od a nd paper absorb w a te r e as i ly. The wet wood and pa p er
may attenuate the radio wave considerably. Execute the communication experiment in a working site in advance using both of dry
materials and wet ones.

Object

• Radio wave reflectors: metal, ground, etc.

Metal reflects a radio wave (microwave) like a mirror reflects light. If there is a metal near an antenna communication area, the commu­nication area is affected by the metal. If a metal is put between an antenna and tag, the communication between the antenna and tag may
fail. Metal, whether metal plate or wire nettin g, may af fec t th e comm unic ation . Also, th e groun d af fe c ts the com muni catio n li ke meta l.

As shown below, a radio wave absorber or reflector can be used to inter rupt a radio wave. When yo u interrupt the radio wave, execute

• Communication area affected by the ground

If an antenna is installed near the ground, radio waves (microwave) emitted from the antenna and ones reflected by the ground overlap
each other. Therefore, an outline of the communication area becomes ragged and complex. In this case, dead zones may be formed fre­quently, where no communication can be made to the tag.

4-1-3 Rainproofing of Antenna

The antenna is not waterproof structure. So, do not install the antenna.

If you must install the ante nn a o utd oors, p r o tect the antenna against rain with a pl asti c rainp roo f b ox. To p reve nt the water droplet com­ing in the antenna through a cable, be sure to turn the antenna cable section downward.

Example of plasti c rainproof box: Model WB-5AJ (Outside dimensions: 571 (H) x 412 (W) x 210 (D) mm, Mirai I ndustry)

Gap between the antenna surface and window plate is 10 to 20 mm.

Example of protection box

Cover the window with an
acrylic plate, etc. 3 mm in
thickness which a radio wave
can penetrate easily.

Size enough to cover
the entire antenna
including a connector.

Drill a large hole for ventilation
and drainage.

If the box is metallic, make
a window on the box. The
window size shall be the
same as the antenna.

Clamp it to prevent the connector
being pulled directly.

Correct Usage

Protective structure IP6 2 of the a ntenna is the pr otecti on agai nst the d rop of w ater. If the antenna is splashed with water
spray or water jet flow, cover the antenna with a protection plate. (Refer to "Appendix 3 - Protective Structure".)

4-1-4 How to Install Tag

♦♦♦♦ Installation

Install a tag on a flat plane taking care not to bend it by force . As shown below, mount the antenna with two M4 screws, spring washers
and flat washers. Tightening torque is 1.2 N•m (approximately 12 kgf•cm) . Do not use any lock paint to fix screws.

(Unit: mm)

♦♦♦♦ Influence on communication performance, adhesive, metal tape, water screen, etc.

• When you apply adhesi ve, etc. on the tag surface, a radio wave (microwave) is at tenuated and the communication area may be
affected. Execute the communi cation experiment with anythin g used actually in advance.

• If a metallic tape, etc. is put on the tag surface, a radio wave is interrupted and the communication to the antenna fails.

• If the tag is put on a glass plate with double-sided adhesive tape as shown below, a gap between the glass plate and tag sweats easily.
Moreover, a water screen may be ge nerated. In thi s case, please n ote that a radio wave is absorbed and the commun ication range
may become small.

5-2 Communication Operation Sequence

Operation sequence, such as communication to a tag and response return timing, varies depending on the designation with a command.
You need to use properly according to the tag sta tus in an antenna communication area and a ty pe of communication with a host device.

5-2-1 Communication Mode with Command

(1) Trigger

Communication is performed to a tag in an antenna communication area when a command has been received. Therefore, check that the
tag is in the antenna communication area and then execute a co mmand. If there is no tag in the antenna co mmunication area when a
command has been executed, th e ant enna returns an error response.

When a command is executed, the tag is in a sleep mode or standby mode.

• Sleep mode (Comm unication designation SU or SN)
The tag battery power can be saved in the sleep mode. The tag cannot be started in 0.2 seconds immediately after sleep.

• Standby mode (Communication designation WU or WN)
To execute several commands consecutively to one tag, enable the standby mode.

5-2 Communication Operat ion Sequen ce

(2) Single Auto

An antenna waits until a tag approaches the communication area and then communicates with the tag.
To terminate Single Auto:

• When an auto repeat cancel command (C2) is issued, the antenna discontinues Single Auto and becomes ready to accept a command.

• When any other comma nd is i ssue d, the anten na disco ntinu es Sing le Au to an d e xecut es th e new co mman d. If th e co mmand forma t
is wrong, the antenna returns the format error response 14 and discontinues Single Auto.

• If a waiting time for tag (refer to Section 5-9-4) is set, when the waiting time for tag has been passed, the antenna returns the no-tag
error response 72 and discontinues Single Auto.

When a command is exe c uted, the tag is in a sle e p mode or standby mode.

• Sleep mode (Communication designation SU or SN)
The tag battery power can be saved in the sleep mode. The tag cannot be started in 0.2 seconds immediately after sleep.

• Standby mode (Communication designation WU or WN)
To execute several com mands consecutively to one tag, enable the standby mode.

5-3

5-2 Communication Operation Sequence

(3) Repeat

When an antenna receives a command from a host device, the antenna wai ts for tag approaching, communicates with the tag whenever
the tag passes the antenna comm unication area, and returns a respon se t o the host device.
After the command is executed, by specifying the sleep state (S

!) as the communication designation, FIFO (First-In First-Out . Refer to

Section 3-1) is enabled.

To terminate repeat state:

• When an auto repeat cancel command (C2) is issued, the antenna di scontinues Repeat and becomes ready to accept a command.

• When any other c ommand is issued, the antenna discontinu es Repeat and execut es the new command. If the command form at is
wrong, the antenna returns the fo rm at error response 14 and discontinues Repeat.

If a waiting time for t ag (refer to Sec tion 5-9-4 ) is se t, when the wa iting time for t ag ha s been p assed, t he an tenna re turns the no-tag error

5-2 Communication Operat ion Sequen ce

5-2-2 Communication Mode with Communication Designation

(1) Polling

When one host device controls several antennas, if a normal auto command is used, a response is returned when the tag communication
has completed. In this case, several antennas return a response. For polling, the antenna returns the response at the request of the host
device. So, some responses are not returned simultaneously and several antennas can be controlled.
To terminate polling:

• When an auto repeat cancel command (C2) is issued, the antenna discontinues Polling Auto/Polling Repeat and becomes ready to
accept a command.

• When any other com mand i s issu ed, t he ant enna d isco ntinu es a pol ling m od e and ex ecu tes the n ew comma nd . If the com man d for­mat is wrong, the antenna returns the format error response 14 and discontinues Polling Auto/Polling Repeat.

• If a waiting time for tag (refer to Section 5-9-4) is set, when the waiting time for tag has been passed, the antenna returns the no-tag
error response 72 and discontinues Polling Auto. For Polling Auto, the antenna returns an error response and continues Polling
Repeat.

When a command is exe c uted, the tag is in a sle e p mode or standby mode accor ding to the communication designation (C!, R!).

5-2 Communication Operat ion Sequen ce

(2) Multi

The communication to all the tags in the antenna communication area can be made. Multi Trigger and Multi Repeat commands are
available:
In Multi Trig ger, the antenna communi cates with all t he tags in the c ommunic ation a rea whe n it rec eives a comman d. Whe n the p rocess
has completed, the antenna ret urns the communication end resp onse (termination code 72).
In Multi Repeat, the antenna waits for a tag when it receives a command. The antenna continues to communicate with all the tags com­ing in the communication area.
To terminate Multi Repeat:

• When an auto repeat cancel command (C2) is issued, the antenna discontinues Multi Repeat and becomes ready to accept a com­mand.

• When any other command is issued, the antenna discontinues Multi Repeat and executes the new command. If the command format
is wrong, the antenna returns the format error response 14 and discontinues Multi Repeat.

If a waiting time for tag (refer to Section 5-9-4) is set, when the waiting time for tag has been passed, the antenn a returns the no-tag error
response 72 and continues Multi Repeat.

When a command is executed, the tag is in a s leep mode according to the communication designation (S!).

An example of Multi Trigger is shown below.

(1) Selective Access

Every tag has an inherent ID code which cannot be rewritten. By using this ID code, communication can be per formed to a particular
tag of those in an antenna communication area.

Executes ID Code Read (I!)

Refer to Section 5-7-2.

Executes Tag Designation Read command

Refer to Sections, 5-7-3, 5-7-5 and 5-7-7.

Reads an ID code of a tag in the communication area.

Uses an ID code and executes a command to a designated tag.

(2) Radio Wave Transmission ON mode

Usually, an antenna transmits a radio wave after receiving a com mand from a host device. When the Radio Wave Transmission ON
mode of antenna is enabled , reg ardless of any command from a host device, the antenna transmits a radio wave al ways. In the Radio
Wave Transmission ON mode, an application that the ID tag moves fast may be avail able.

After an antenna writes data into a tag, the antenna reads the data from the tag
and check whether the data is correct. If the data is not correct, the termination
code becomes 71. Writing is reliable, but the communication time with verification
read is twice the length of that withou t verification read.

After an antenna writes data into a tag, the antenna does not read the
