FCC NOTICE
This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment dose cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.

-Consult the dealer or an experienced radio / TV technician for help.

FCC WARNING
Changes or modifications not expressly approved by the party responsible for compliance could

void the user’s authority to operate the equipment.
Properly shielded an grounded cables and connectors must be used for connection to host
computer and / or peripherals in order to meet FCC emission limits.
AC adapter with ferrite core must be used for RF interference suppression.

Precautions of Use

This device uses a frequency of 125 kHz to communicate with a tag. Some transceivers,
motors, monitor units, and power supply (power IC) emit noise that adversely affects this
communication with the tag. If this product is to be used in an environment close to such
devices, please check the effects from these devices prior to use.
To minimise the effect of noise, please ground any metal object surrounding this device.

3.2 Oscillation Control

The R/W Module supplies power to the Tag by oscillating the antenna, and thus
conducts communication with the Tag. The Module may be set on either the
“Oscillate Mode” “Stop Mode” depending on whether the Module should oscillate
while not in communication with the Tag. The “Stop Mode” conserves dissipation
power, and enables the R/W Module antenna to be installed close to the Tag to
conduct communications on a time sharing basis. The “Oscillate Mode” allows the
Module to constantly supply power to the Tag for FIFO processing.

Trigger / FIFO Auto Command

(10/23)

3.3 Input STOP

When a STOP signal is input to the R/W Module, receiving and processing of
commands and command processing will stop and then, after the STOP signal is
deactivated, the Module will be on stand by for new commands. When the STOP
signal is input, oscillation will stop regardless of the setting of the oscillation control
mode.
If a STOP signal is input more than 50 msec prior to shut down, writing of unstable
data to the Tag may be prevented. However, if writing of the command in process
requires more than one page, not all pages may be completely rewritten.

3.4 Memory Management on Tag

The Tags used to conduct communication with the R/W Module may be one of the
following two types depending on memory capacity: 128 bytes (user area 112 bytes)
or 256 bytes (user area 240 bytes). The memory area recognizes every 8 bytes as
one page, distinguished by such addresses as 00h ~ 07h, 08h ~ 0Fh, and so on.

3.5 Processing Tag Memory

Tag 1

(1) Process Contents

The following three processes may be executed on the Tag Memory

1) Read
Reading data from Tag Memory. The area to execute the Read command

may be selected at random up to 16 pages.

2) Write
Writing data onto Tag Memory. The area to execute the Write command

may be selected at random up to 16 pages. When writing the same data
onto all pages (multiple write), there is no limitation on the number of pages.
Certain data within a page may be selected in units of bytes to be written
onto the Tag Memory (byte write).

3) Write Protection Set/OFF
Write protection may be set on the selected pages of Tag Memory. When

write protection is set, the data may be read, but not re-written. Write
protection may be set on any of the pages. Write protection may be set or
turned off by commands.

Tag Operation

The following 6 communications operation may be executed by changing the
process procedure and execution timing. Communication operations may be
specified by commands during command transmission.

1) Single Trigger
Communication with Tag will be executed immediately after receiving

command and a response will be transmitted. After response is transmitted,
the Module will be on stand by for new commands. During communication
with the Tag, there may only be one Tag within the communication area.

♦ Operation Sequence
Processing will be executed once only after receiving command. If there is

no Tag, a Tag absent error message will be transmitted.

communicates with the Tag, and then transmits a response. Once the
response is transmitted, Module will be on stand by for new commands.
During communication with the Tag, there must be one Tag within the
communication area.

♦ Operation Sequence
After receiving command, the Module waits for the Tag to approach, then

executes process once only after Tag is detected. When Module receives a
STOP command, the command will be completed.

3) FIFO Trigger
Module will communicate with Tag immediately after receiving command

and transmit response. After communication is completed, Module will
prohibit Tag from operating. Module will be on stand by for commands after
response is transmitted. During communication with Tag, there MUST BE
AN OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM
OPERATION) within the communication area. When this command is
executed, Module automatically activates “Oscillation Mode”

♦ Operation Sequence
Upon receiving command, Module will execute process once only. If there

is no Tag, a Tag absence error will be transmitted. During processing of the
command, Tag will become inoperative, and thus will not respond to the
next command. Oscillation will continue after command is processed.

the Tag, there MUST BE AN OPERATIONAL TAG (A TAG THAT IS NOT
PROHIBITED FROM OPERATION) within the communication area. When
this command is executed, Module automatically activates “Oscillation

executes process once only after Tag is detected. During processing of the
command, Tag will become inoperative, and thus will not respond to the
next command. Oscillation will continue after command is processed.

5) FIFO Continue
After receiving command, the Module waits for the Tag to approach, then

communicates with the Tag and transmits a response. After communication
is completed, Tag will become inoperative. After transmitting a response,
Module will await Tag to approach again if it receives [ACK], and
CONTINUE UNTIL MODULE RECEIVES A STOP COMMAND. When
communicating with the Tag, THERE MUST ONLY BE ONE ACTIVE TAG
within the communication area.

♦ Operation Sequence
Upon receiving the command, Module awaits Tag to approach. When Tag

is detected, Module executes command and transmits a response.
Afterwards, when [ACK] is received, Module repeats the same operation.
Once process is executed on a Tag, the Tag becomes inoperative, and thus
a Tag will only be processed once. When Module receives a STOP
command, processing will stop.
