21. Descriptions of action for each part 1.1 ID number indicating section In this product, 4 antennas can be conneted for use, and for the following 7 segments, individual numbers of the antennas currently used are indicated. Initial value is set up as 1, and if the setting up is to be changed, refer to the description of setting up section of the following ID numbers. <Fig. 1> Outline drawing of RFID <Table 1> Indicated details of 7 segments ID No. Indicated details ID No. Indicated details 0 8 1 9 2 10 3 11 4 12 5 13 6 14 7 15 O(No error) X(Occurrence of error) ID No. RD WR RST Tx Rx ANT4 Ethernet PowerRFID Reader ANT3 ANT2 ANT1
3For the segment indicated with individual number, refer to the above <Table 1>. For the range of ID number, 4 numbers can be set up with 1~4. 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. 1.4 LED for indicating data transmitting and receiving state: Tx, Rx When transmitting data from Host to RFID Reader, Rx LED is lighted, and when receiving, Tx LED is lighted.

93.2 Structure of protocol For basic communication, ASCII character string is used, and structure of transmitting and receiving instructions are as follows. Basic structure of frame is started with Device ID, and it is comprised of CheckSum 1Byte. Data is continuously sent without using special character between each of the parameters. <Table 7> Structure of transmitting instruction T_ID CMD(Transmitting instruction) D1D2 …. Dn Check Sum Low rank -> High rank byte 1Byte 1Byte Variable 1Byte <Table 8> Structure of receiving instruction 1) T_ID(Target ID) : Function of antenna number selection This is the setting up for selecting the channel (antenna number) of multi-channel RFID reader, and the antenna can be selected as follows. This function can be set up through communication instruction from Host, and it is comprised of 1Byte. The ASCII characters with the range of 0~4(0x30~0x34) are used. Initial setting up value at the time of product shipping is 1, and when reset is conducted with RST switch or through communication instruction, the value can be changed into the initial setting up value, 1. This setting up value is used to select antenna when R, W instructions are performed, and other instructions are disregarded. <Table 9> ASCII code table of T_ID (antenna channel selection) T_ID number ASCII code Antenna number 0 0x30 X 1 0x31 1 2 0x32 2 3 0x33 3 4 0x34 4 5 ~ 15 0x35~ 0x3F X *) X : This is the data which is not used, and all antennas are turned off.

102) CMD This indicates instructions sent from Host to Reader, or from Reader to Host. For the type of instructions currently realized, refer to the section 2.3. Configuration and length of data will be differed in accordance with the type of these instructions. 3) D1 D2 …. Dn Data related with each of the instructions and reply codes are used. Maximum length of data is limited within 9 bytes. For R and W instructions, the page information of 1 byte will be used to set up the page. For the setting up value of page, refer to the following types of instruction. 4) STS 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 0000 0010 0x38 0011 1000 XOR 0011 1010 0x0D 0000 1101 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.

185. 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 <Table 15> 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 <Fig. 8>. <Fig. 7> Dimension of circular antenna <Table 15> Characteristic for each type of antenna Type of antenna Name of item Recognition distance Characteristic (Noise environment) Example of use 62mm Stick CTS-RFID-ANxx 90mm Excellent Stocker 162mm Stick CTS-RFID-ALxx 85mm Ordinary OHT The xx under the name of item of <Table 15> means the length with the unit of 10cm, and it is limited in the range from 01, which is 0.1m, to the maximum of 50, which is 5m. Recognition distance means the straight distance between the antenna end to tag as shown in the <Fig. 8>. The data measured under no-noise environment can be different from the one measured under actual using environment. 62mm13mm 2M BNC connector
19 <Fig. 8> Standard of recognition distance Recognition distance
205.2 Setting up method of optimum location 1) As in the <Fig. 9-A>, 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 <Fig. 9> Recognition distance (Read) in accordance with arrangement of antenna and tag
21 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. <Fig. 8> 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.
