.
1. Do not install model V690-HMG01, model V690-D8KR01 and model V690-L01 in the following areas:
• Place exposed to the direct sunlight.
• Humid place where moisture condensation may occur.
• Place affected by vibration or impact.
2. Preliminary check of installation site.
This device uses the frequency band 2450 MHz for the communication between an antenna and tag. Some of radio equipment, such
as wireless LAN, cellular phone, personal handyphone system and transceiver, motor and switching power supply may generate a
radio wave (noise) which affects the communication with a tag. If you must use this device near such heater, we would like to ask
you to check the influence in advance.
To minimize general influence of noise, follow the instructions below:
• Ground any metallic material located around this device according to Class D (Class III).
• Wire this device keeping away from high voltage and heavy 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 water and human body absorb it. Locate an antenna and tag in the communication range and check the
radio wave environment in advance.
• The Read/Write antenna model V690-HMG01 has a communication test command to check the radio wave environment 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.
5. Cleaning of model V690-HMG01, model V690-D8KR01 and model V690-L01
• Do not use any thinner. Resin material and case paint are dissolved by thinner.

1. Radio interference between radio stations
The frequency 2450 MHz band (2434.25 - 2465.75 MHz) used by the microwave RFID system V690 is designated for second-gen-
eration low-power data communication system (wireless LAN), local area radio station (a license required) for mobile object identi-
fication and specified low-power radio station (no license required) as well as industrial, scientific or medical equipment such as
microwave oven. Therefore, the radio interference is expected in such frequency band. Moreover, the cellular phone and personal
handyphone system (900 MHz - 1900 MHz) may generate the radio interference.
2. Possible trouble due to radio interference
• Communication failure in RFID system
The radio wave from an ID tag to antenna is weak and, therefore, the communication between the antenna and ID tag may fail due
to radio interference caused by any other devices. Keep sufficient space between the RFID system and any other devices. For the
space, refer to Section 7-6.
• ID tag battery power loss
An electronic circuit in the ID tag is started by a radio wave of other device and the battery power may be consumed considerably.
V690 has a tag power-saving function (refer to Section 3-7) to control the battery power. Nevertheless, the battery power may be
still consumed depending on a working environment. So, keep sufficient space between the ID tag and any other devices. For the
space, refer to Section 7-6.

• Consists of an antenna unit which communicates with the ID tag, and a controller unit which controls the communication.
• The antenna unit has achieved the transmission speed 600 kbps and maximum communication range 5 m.
• The antenna uses circularly polarized wave as radio wave. So, the ID tag facing the antenna can communicate at any rotating
angle on the medial axis. The 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 function which enables to access several tags in the antenna communication area and FIFO (First-In First-Out)
function which enables to access the tags coming in the communication area sequentially one by one.
• By a command from a host device, the communication 2 m Mode and 5 m Mode can be switched to each other and a radio wave
channel can be switched at a working site. You can select the most suitable communication range at a working site and prevent
the mutual interference between antennas easily.
• The controller contains both of the RS-232C and RS-422A interfaces. So, it can connect to a general-purpose PC or programma-
ble controller (PLC) which have RS-232C. Also, several antennas can be connected to one host device.
• A simplified communication test function, which can check the communication with a tag without a host device, and a communi-
cation test, which can check a radio wave environment at a working site, are available.
(2) ID Tag Model V690-D8KR01
• This tag contains a battery and the memory capacity is 8 kbytes.
• Write Protect is available to disable writing by 256 bytes.
• Protective structure based on the IEC Standard IP67 (JEM Standard IP67g) has been achieved. So, this tag can be used even in a
place splashed with water and oil.
• The battery life is 5 years at 25°C (a reference value). The battery is not replaceable, but a power-saving function and battery
voltage alarm function are available.
(3) RS-422A/485 Link Unit Model V690-L01
• Use when the communication with a host device is made through the RS-422A or RS-485.
• The power supply to the Read/Write antenna can be turned ON/OFF, the operation/setting mode can be switched, RS-422A/RS-
485 can be switched and terminating resistance can be turned ON/OFF.

2-6 Communication Specifications
3-1
You can use one of the three communication modes according to the number of tags in the communication 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 commu-
nication area. In the Single mode, only one tag must be placed in the antenna com-
munication 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 tags 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 antenna communication area, such tag can communicate again.
(3) Multi mode
When there are several tags in the antenna communication area, the Multi mode
enables to access all those tags. By using the Selective Access function, the com-
munication can be made to a specified tag of those in the antenna communication
area.
Correct Usage
When you use the FIFO mode, only one tag must be placed in the antenna communication area. If two or more tags are
in the antenna communication area, a communication error occurs. Then, the communication cannot be recovered from
failure unless only one tag is in the antenna communication area.

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 available. Those channels can be switched 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).
Correct Usage
Due to dispersion of frequency, the frequencies of adjacent channels may overlap each other. Do not assign consecu-
tive numbers to the channels of adjacent antennas.

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 communication test stops.

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 this test. The communication is not retried. Refer to Section
5-7-8.
(1) Create a communication program at a host device.
(2) Enable the operation mode. (Disconnect the terminals "+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 communication test command (Section 5-7-8). If the antenna is 00, the command is [STX]0080T0SU[ETX].
(6) If the antenna responds to the host device, the communication between the host device and antenna has been made successfully.
(7) In the response [STX]8000T0000256 [ETX], a radio wave environment value is between 0000 and 0256. If the value is
close to 0000, the communication to the tag is stable.

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 "Notes on Interference to Second-Generation Low-Power Data Communication System (Wire-
less 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 "Appendix 1 - Glossary") at every 100 msec after emitting 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.
Antenna radio wave emission
Wake instruction
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.

♦♦
♦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 place it in the communication area again.

4-1-1 Installation Environment
(1) Antenna and tag
Install the antenna and tag so that those front faces can face each other. Confirm the front side and the reverse side of them. The front
faces must face each other.
(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 adjacent 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 communicate with
the antenna at any rotating angle.
The maximum communication range varies depending on the rotating angle of the tag. Refer to Section 7-3.
• Conceptual diagram of circularly polarized wave
The arrows show the directions of vibrating surface. The radio wave propagates while the vibrating surface is rotating.

(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 liquid) other than metal, but it is attenuated while penetrating. In partic-
ular, 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 remarkably in a human body which contains much water. So, any solid body and liquid must not 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 attenuated 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 attenuate the radio wave so much. However, wood and paper absorb water easily. The wet wood and paper
may attenuate the radio wave considerably. Execute the communication experiment in a working site in advance using both of dry
materials and wet ones.
• 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 commu-
nication 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 netting, may affect the communication. Also, the ground affects the communication like metal.
As shown below, a radio wave absorber or reflector can be used to interrupt a radio wave. When you interrupt the radio wave, execute
the communication experiment in a working site in advance.
Example of radio wave absorber: ECCOSORB AN75 (61 x 61 cm, E&C Engineering)

• 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 fre-
quently, where no communication can be made to the tag.
Correct Usage
Depending on a working site, a special point may be generated in the communication area above and the communica-
tion to the tag cannot be made at the point. So, be sure to execute the communication check with a communication test
(refer to Section 3-5), etc.

(5) Installation environment
Do not install the antenna and tag at any place below:
• Place where the ambient temperature is out of the range between -20 and +60°C for the antenna and -25 and +70°C for the tag, where
the temperature fluctuates considerably and where moisture condensation occurs frequently.
• Place where the relative humidity is out of the range between 35 and 85%RH.
• Place where there is corrosive gas, flammable gas, dust, salt or iron powder.
• Place affected by vibration or impact.
• Place splashed with water, oil or chemicals
4-1-2 How to Install Antenna

4-1-3 Rainproofing of Antenna
The antenna is not waterproof structure. So, do not install the antenna.
If you must install the antenna outdoors, protect the antenna against rain with a plastic rainproof box. To prevent the water droplet com-
ing in the antenna through a cable, be sure to turn the antenna cable section downward.
Example of plastic rainproof box: Model WB-5AJ (Outside dimensions: 571 (H) x 412 (W) x 210 (D) mm, Mirai Industry)
Correct Usage
Protective structure IP62 of the antenna is the protection against the drop of water. 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".)
Gap between the antenna surface and window plate is 10 to 20 mm.
Size enough to cover
the entire antenna
including a connector.
Example of protection box
Drill a large hole for ventilation
and drainage. Clamp it to prevent the connector
being pulled directly.
If the box is metallic, make
a window on the box. The
window size shall be the
same as the antenna.
Cover the window with an
acrylic plate, etc. 3 mm in
thickness which a radio wave
can penetrate easily.

♦♦
♦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.
♦
♦♦
♦Influence on communication performance, adhesive, metal tape, water screen, etc.
• When you apply adhesive, etc. on the tag surface, a radio wave (microwave) is attenuated and the communication area may be

• 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 generated. In this case, please note that a radio wave is absorbed and the communication range
may become small.

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 status in an antenna communication area and a type 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 command. If there is no tag in the antenna communication area when a
command has been executed, the antenna returns an error response.
When a command is executed, the tag is in a sleep 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 commands consecutively to one tag, enable the standby mode.

(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 command is issued, the antenna discontinues Single Auto and executes the new command. If the command format
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 executed, the tag is in a sleep 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.

(3) Repeat
When an antenna receives a command from a host device, the antenna waits for tag approaching, communicates with the tag whenever
the tag passes the antenna communication area, and returns a response to 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 discontinues Repeat and becomes ready to accept a command.
• When any other command is issued, the antenna discontinues Repeat and executes the new command. If the command format is
wrong, the antenna returns the format error response 14 and discontinues 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 continues Repeat.

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 command is issued, the antenna discontinues a polling mode and executes the new command. If the command for-
mat 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 executed, the tag is in a sleep mode or standby mode according to the communication designation (C!, R!).

5-2 Communication Operation Sequence
5-7
(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 Trigger, the antenna communicates with all the tags in the communication area when it receives a command. When the process
has completed, the antenna returns the communication end response (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 com-
ing 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 com-
mand.
• 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 antenna returns the no-tag error
response 72 and continues Multi Repeat.
When a command is executed, the tag is in a sleep mode according to the communication designation (S!).
An example of Multi Trigger is shown below.

The antenna does not transmits a radio wave when
it waits for a command. When the antenna accepts
a communication command, the antenna transmits
a radio wave and communicate with a tag. When
the communication has ended, the antenna stops
transmitting a radio wave.

(1) Command
A text section of command consists of a command and option section which specifies information. The antenna receives a range from
STX receiving to ETX correctly and, only when the antenna station No. and DA match, executes a command. After receiving STX,
when the antenna receives STX again by the time the antenna receives ETX, the second STX shall be the beginning of the command.
You can specify whether BCC is enabled or disabled. By default, BCC is disabled. How to specify whether BCC is enabled or disabled,
refer to Section 5-9-7.
Note: "h" is a hexadecimal notation.
(2) Response
A text section of response consists of a command, termination code and data section.
Name Description
STX Shows the beginning of a command response frame. It corresponds to 02h (hexadecimal number)
in the ASCII code table.
DA Destination (antenna) station number. Operation mode "00" to "31" (initial value is "00"). Setting
mode "99". A station number in the operation mode can be changed in "Station Number Setting".
SA Source (host device) station number "80" to "89". Several host device can be used. If only one
host device is used, specify "80".
Command Code Specifies a command for antenna operation. For available command codes, refer to the command
list in Section 5-4.
Option Specifies the communication of command execution, reading data and writing data. For details,
refer to the formats of commands after Section 5-7.
ETX Shows the end of command response. It corresponds to 03h (hexadecimal number) in the ASCII
code.
BCC Block Check Character (referred to as "BCC"). Calculation result of horizontal parity immediately
after STX to ETX. It is displayed in one character. For example of calculation of BCC, refer to the

Depending on a type of command and the communication designation, the command transmission from a host device to an antenna and
the response from the antenna to the host device vary.
(1) No response
When the host device issues a reset command to the antenna, the antenna does not send any response, performs resetting and waits for a
command.
(2) One to one
When the host device issues Single Trigger and Single Auto of a tag communication command, or when the host device issued an
antenna operation command and antenna setting command, the antenna returns one response per command.
(3) Several responses
When the host device issues Single Repeat, Multi Trigger and Multi Repeat, the antenna returns several responses per command.

5-7-8 Communication Test
To check a radio wave environment, 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 this text.
The communication is retried in active use. However, the communication is not retried in a communication test.

A smaller radio wave environment value shows a better radio wave environment.
(The radio wave environment value is the number of failed communication of total 256 com-
munications. In the communication test, communication is not retried. However, the com-
munication is retried when the communication fails in an actual operation. If the radio wave
environment value is 50 or less, a communication error does not occur in an actual opera-
tion.)

(3) How to calculate maximum movement speed of tag
The maximum movement speed of tag moving at the front of antenna is calcu-
lated as follows:
Travel in communication area
Communication time
Example of calculation (1)
Calculate the movable speed of tag, based on the distance 1 m between the antenna and tag and 32-byte read.
If the distance is 2 m in the communication range 2m mode, the area width is 0.8 m.
The communication time of 32-byte read is 12 ms.
0.8 m 0.8 m
12 ms 0.012 x 1 / 60 (minutes)
Example of calculation (2)
Calculate the movable speed of tag, based on the distance 4 m between the antenna and tag and 256-byte read.
If the distance is 4 m in the communication range 5 m mode, the area width is 1.5 m.
The communication time of 256-byte read is 19 ms.

Correct Usage
The tag movement time above is a value of the best example. In an actual operation, taking into consideration periph-
eral objects and radio wave environment at the working site, design a system that a margin was removed from the calcu-
lated value and execute a test in the working site.

Common physical interface standard of EIA (Electronics Industries Association). Communication speed 9600 bps can be achieved
in communication range 15 m.
RS-422A
Common physical interface standard of EIA (Electronics Industries Association). RS-422A is more excellent in noise resistance
than RS-232C and a maximum of 3000 m of communication range is available. Communication is performed through four wires.
Two wires are for sending and the others are for receiving.
RS-485
Common physical interface standard of EIA (Electronics Industries Association). The same line is used for both of sending and
receiving. So, communications can be made through two wires.
Second-generation low-power data communication system
Remarkably applicable wireless LAN which was legislated in 1999. A wide range of frequency band 2400 to 2483.5 MHz can be
used by the SS (Spread Spectrum) system and multiple channels are available. ARIB RCR STD-33 (1999) is the Standard.
Sleep, sleep state
The state that any communication to the Read/Write antenna is not performed. In this state, battery power is used only to back up
data in SRAM and the power consumption is 1/100 or less of the state that the ID tag operates or communicates. Therefore, to
extend the life of the battery of ID tag, we recommend you to put the ID tag in the sleep state whenever the ID tag does not work.
When the ID tag receives a radio wave from the Read/Write antenna, the ID tag quits the sleep state and works.
Specified low-power radio station
A radio station that the antenna power is 10 mW or less. A user is not required to apply a license for radio station. This product is
verified by Technical Regulation Conformity Certification of an official organization before shipment.
SRAM
Static RAM (Random Access Memory). Volatile memory. Data is backed up by battery.
Standby, standby state
The state that all the circuits in a tag are ready to operate after a command is executed. The battery power consumption is the same
as that at an operation such as communication. As a period of the standby state becomes short, the life of the battery can be extended.
Start-stop synchronization
Asynchronous data communication system which does not use synchronizing clock. Communication line is only one. Use it when
synchronizing clock cannot be sent.
Tag
In this manual, this refers to ID tag which is memory media accessed by the Read/Write antenna of the RFID system. As accurate
technical term, this is referred to as "Transponder". We call it "Tag" because "Transponder" is hard to say.
Terminating resistance
Put at both ends of communication line to prevent reflection in the communication line in RS-422A/RS-485.
Time slot
One of the systems that the Read/Write antenna accesses several ID tags. This system adopts the time slot. For example, if "M" (the
number of time slots = 16) is specified in the data exchange designation of a command, the antenna informs the ID tag that there are
16 time slots and every ID tag returns a response according to timing of any of 16 time slots. If responses of several ID tags collide
with each other, the time slots for those tags are rearranged. For "M", if the number of tags are approximately 8, probability of rear-
rangement is reduced and the total data exchange time is not prolonged so much.
Appendix 1 Glossary
Appendix-3
Wake instruction
A command for identification transmitted at every 100 msec when the Read/Write antenna transmitted a radio wave. The ID tag only
can identify it. When the ID tag receives the wake instruction, the ID tag continues an operation. If the ID tag cannot receive the
wake command, the ID tag enters the sleep state. The ID tag power-saving function described in Section 3-7 is achieved by utilizing
this function.
