1.2 Setting up method of ID number
Setting up of ID number can be revised through communication at high rank controller. For
detailed information, refer to protocol specification.
1.3 Switch for tag test
In order to find optimum action condition when installing antennas of tag and RFID, it needs
to be confirmed whether the functions of reading and writing of tag are normally conducted
at RFID Reader. For these kinds of functional tests, RD (Read) and WR (Write) switches are
used. When pressing RD switch, if data is normally received by sending the reading
instruction to the tag, O. will be expressed at 7 segments for indicating ID No., and when
error is occurred, X. will be lighted. When WR switch is pressed with identical method,
abnormal state will be indicated after writing again the data value which has been read at
the tag. WR will basically be progressed only when there isn’t any abnormality after
conducting the reading test. In addition, WR button is combined with the function of
manually increasing the antenna number with the increment of 1. Therefore, when the
antenna number is changed, WR button is supposed to be pressed until the antenna with
desired number is selected. It shall be cautious that as this is acted together with WR
function, when this function is used, the information of tag’s last page can be changed into
an arbitrary data.

This is the data to be used for sending various information such as communication state
at RFID Reader, action state of product, etc. For details of information, refer to the section
2.4.
5) Check Sum
This is the function to be used for confirming any abnormality of transmission and
reception data, and when calculating the Check Sum, all of the transmitted data are used,
and the calculation formula is sent by converting into ASCII code 1 Byte in which 0x30 is
added to low rank 4Bit of the resulting data which obtains XOR operation for each bit.
Example) When it is 0x35 0x37 0x38 0x0d 0x0a:
0x35
0011 0101
0x37
0011 0111

XOR
0011 0111
0x0A
0000 1010
XOR
0011 1101 = 0x3D => Only low rank 4Bit+0x30=”0x3D” is transmitted.
Example) When the data resulting from XOR is
0x56: it will be transmitted by configuring frame with 0x36=(0x56&0x0F)+0x30, or when
it is
0x0F: it will be transmitted by configuring frame with 0x3F=(0x0F&0x0F)+0x30.

5. Installation method of ANT
5.1 Specification of ANT
PVC is used as outer shell material, and length and thickness of cable can be changed in
accordance with ordered specification, however, it is desirable to use the cable within the
maximum length of 5 m. For the antenna to be used in this reading device, the two types of
antennas shown in the following can be used as the standard, and the antenna
with special specification can separately be manufactured. For the 162mm antenna, it will
be the good antenna with fine reading performance when the tag is vertically placed at the
side of the antenna rather than the one with the structure shown in the .

5.2 Setting up method of optimum location
1) As in the , the longest recognition distance can be used for the case of
confronting the antenna of RFID Reader and the tag face-to-face with each other, and
when the direction is deviated, the recognition distance will be shortened.
2) In order to prevent malfunction by the noise radiated from peripheral devices, installation
shall be conducted so that interference with monitor, switching relay, adjacent
transponder (tag), and so forth will not be generated. During the installation, if the noise
source in the vicinity is located and eliminated, recognition distance and speed can
largely be enhanced.
3) During the installation, it shall be careful not to have metallic part in the vicinity of antenna
and tag. If there is any metallic part in the surroundings, recognition distance can be
shortened due to the generation of abnormality at RF signal created from the antenna.
Therefore, even in the case of the fixtures securing antenna, it is desirable for them to
be processed with insulation material like acetal, and if existence of stainless steel or
aluminum in the surroundings is unavoidable, the antenna with special shape or
shielding method shall be required.
(A) When antenna and tag are in the same axis
(B) When antenna and tag are perpendicular with each other
Recognition distance (Read) in accordance with arrangement of antenna and tag

5.3 Recognition distance
In order to raise recognition distance, locations of Tag and RFID Reader shall be arranged
on a horizontal line, and it shall be careful not to make other metallic items placed near to the
antenna and tag during installation. is a schematic which indicates the recognition
distance in accordance with the arrangement of antenna and tag, and the most desirable
arrangement is the one when the antenna and tag are placed on a same axis, and if they are
placed in vertical arrangement, the tag is desirable to be installed not at the center but at the
end section of the antenna body. For recognition distance, securing sufficient allowance is
required, therefore, the allowance of recognition distance shall always be confirmed under the
arranged state while testing normal reading state with read switch of the reader.
