Precautions of Use
This Product 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 product.

3. Operations of the Reader Writer
3.1 Outline of Operations
The Reader Writer receives commands from the High-end device, executes read /
write processes on the Tag, and returns a response of the results of the process to
the High-end device. The status of the Reader Writer operations will be reflected
on the Output / LED.

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

3.3 Memory Management on Tag
There are two types of the tag in the memory capacity: 128 bytes (user area 112
bytes) and 256 bytes (user area 240 bytes). The memory area recognises every 8
bytes as one page, distinguished by such addresses as 00h ~ 07h, 08h ~0Fh, and
so on.

3.4 Processing of Tag Memory
(1) Process Contents
The following three processes are executed on the Tag Memory
1) Data Read
Reading data from Tag Memory in units of pages. The area to execute the
Read command is selected at random up to 16 pages (CR control) / 28 pages
(Number of characters control).
2) Data Write
Writing data onto Tag Memory. The area to execute the Write command may
be selected at random up to 16 pages (CR control) / 28 pages (Number of
characters control). When writing the same data onto all pages (multiple
write), there is no limitation on the number of pages. Certain data may be
selected in units of bytes to be written onto the Tag Memory (byte write).
3) Write Protection Set/Clear
Write protection is set on the selected pages of Tag Memory. When write
protection is set, the data may be read, but not be written. Write protection
may be set on any of the pages. Write protection may be set or turned off by
commands. Set / Clear is conducted by using the write protect command (08).
(10/30)
(2) Transmission Operations
The following 6 transmission operations are executed by changing the
process procedure and execution timing. Transmission operations are
specified by commands during command transmission.
1) Single Trigger
Transmission with Tag is executed immediately after receiving command
and a response is transmitted. After response is transmitted, the Reader
Writer will be on stand by for new commands. During transmission with
the Tag, there must be only one Tag within the transmission area.
♦ Operation Sequence
Processing is executed once only after receiving command. If there is no
Tag, a Tag absent error message will be transmitted.
2) Single Auto
After receiving command, the Reader Writer waits for the Tag to
approach, communicates with the Tag, and then transmits a response.
Once the response is transmitted, the Reader Writer will be on stand by
for new commands. During transmission with the Tag, there must be one
Tag within the transmission area.
♦ Operation Sequence
After receiving command, the Reader Writer waits for the Tag to
approach, then executes process once only after Tag is detected. When
the Reader Writer receives a STOP command, the command will be
completed.
