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).
Page 10
(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.

3) FIFO Trigger
The Reader Writer will communicate with Tag immediately after
receiving command and transmit response. After transmission is
completed, the Reader Writer will prohibit Tag from operating. The
Reader Writer will be on stand by for commands after response is
transmitted. During transmission with Tag, there MUST BE AN
OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM
OPERATION) within the transmission area. When this command is
executed, the Reader Writer automatically activates “Oscillation Mode”
♦ Operation Sequence
Upon receiving command, the Reader Writer 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 Tags
that have completed transmissions will not respond to the next command.
Oscillation will continue after command is processed.
4) FIFO Auto
The Reader Writer will await Tag to approach after receiving command,
then communicate with Tag and transmit response. After transmission is
completed, the Reader Writer will prohibit Tag from operating. The
Reader Writer will be on stand by after response transmission is
completed. During transmission with the Tag, there MUST BE AN
OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM
OPERATION) within the transmission area. When this command is
executed, Module automatically activates “Oscillation Mode.”
♦ Operation Sequence
After receiving command, the Reader Writer waits for the Tag to
approach, then executes process once only after Tag is detected. During
processing of the command, Tag will become inoperative, and thus Tags
that have completed transmissions will not respond to the next command.
Oscillation will continue after command is processed. When the Reader
Writer receives a STOP command, the command will be completed.
However, oscillation after completion of command continues.

5) FIFO Continue
After waiting for the Tag to approach, then communicates with the Tag
and transmits a response. After transmission is completed, Tag will
become inoperative. After transmitting a response, the Reader Writer will
await Tag to approach again if it receives [ACK], and CONTINUE UNTIL
THE READER WRITER RECEIVES A STOP COMMAND. When
communicating with the Tag, THERE MUST BE ONLY ONE ACTIVE
TAG within the transmission area.
♦ Operation Sequence
Upon receiving the command, the Reader Writer awaits Tag to approach.
When Tag is detected, the Reader Writer executes command and
transmits a response. Afterwards, when [ACK] is received, the Reader
Writer 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 the Reader Writer receives a STOP command, processing will
stop.
6) FIFO Repeat
After waiting for the Tag to approach, then the Reader Writer
communicates with the Tag and transmits a response. After transmission
is completed, Tag will become inoperative. THE READER WRITER
WILL CONTINUE PROCESS UNTIL IT RECEIVES A STOP COMMAND.
When communicating with the Tag, THERE MUST BE ONLY ONE
ACTIVE TAG (A TAG THAT IS NOT PROHIBITED FROM OPERATION)
within the transmission area.
♦ Operation Sequence
Upon receiving the command, the Reader Writer awaits Tag to approach.
When Tag is detected, the Reader Writer executes command and
transmits a response. Afterwards, the Reader Writer 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 the
Reader Writer receives a STOP command, processing will stop.

(25/30)
5.3 Communication Time
The Model V700 Series has two communication times: the transmission time and
the TAT (Turn Around Time).
(1) Transmission Time
This is the transmission processing time between the Reader Writer and the
Tags. This time varies in accordance with the number of pages to be read /
written.
The transmission time values are as indicated below. This value is estimated
based on the assumption that the transmission operation is on trigger mode
and that there is no interference in transmission due to noise and other
causes.
(2) TAT
This is the time required for the high-end unit to transmit a command to the
Reader Writer, and to complete receipt of a response. This time varies in
accordance with the transmission speed and the communication control mode.

6. The Influence of Requirements of Use on Transmission
Distance (Reference Values)
When using the Reader Writer, transmission distance varies in accordance with the
requirements of use (the existence / non-existence of metal objects in the vicinity, the use
/non-use of multiple Reader Writer, power voltage value, etc.). This section indicates how
such requirements and changes in them affect communication distance. Please use the
following figures for your reference. Note that all values indicated in this section are
reference.
6.1 Influence of Metal Objects Surroundings and Metal Objects Behind the
Device
When metal objects are around or behind the Reader Writer, transmission
distance deteriorates. Please take note of the distance between the metal objects
and the Reader Writer as per below when using the Reader Writer.
When the metal object is steel, the relationship between the distance of the metal
objects around and behind the Model V700-HMC71 from the device and the
transmission distance (read / write) is indicated below. The following values were
obtained by using Tags Model V700-D13P31 / Model V700-D13P21 with an axis
variation of +- 0 mm.

6.2 Mutual Interference between Reader Writers
When using more than one Reader Writer, to prevent erroneous operations due to
interference from other Reader Writers, please be sure to check that the belowindicated distance between Reader Writers is secured.
n When Using Multiple Reader Writers in a Line
410mm or more
n When Using the Reader Writers Facing Each Other

6.3 Effects of Antenna Angle
Please install the Reader Writer and Tags so that they are parallel to each other
whenever possible. The Reader Writer and Tags can communicate when installed
on angles, but the transmission distance will be shorter. The relationship between
angles and transmission distance is as indicated below. The following values were
obtained by using Tags Model V700-D13P31 / Model V700-D13P21.
