First the tag must be power up. Next command initialize a tag using the anticollision or inventory command. A selection of a tag is necessary to interact with a tag of interest especially if more than one tag is present at the same time. Only selected tags are capable to response to higher commands such as read or write page data. READY state A tag enters the READY state after it receives a valid inventory or anticollision command. At this state the tag all serial numbers are known and the tag is ready to select. ACTIVE state After a selection the tag is in the ACTIVE state. Only an activated tag can respond to a read or write command. HALT state The HALT command disables a tag for further communication. The tag is still in the field but dies not respond to any command. To activate a tag and to put it back to the Ready state a WAKE-UP command has to be used. Power off Ready ACTIVEHALT Anticollision Loop,InventoryWAKE-UP ApplicationSelect

13,56 MHz Multitag Reader Module, Version 0.9v ACG Identification Technologies AT Page 7 3.3 ISO 15693 The reader can communicate with ISO15693 tags. An anticollision is needed if multiple instances of tags are in the same antenna field. The reader detects each type of ISO15693 labels and handles them individually 3.3.1 Coding of UID The UID of a tag is defined in ISO/IEC 15693-3. All tags compliant to ISO15693 support the specified format. The UID is factory programmed and cannot be changed. The UID is needed for the anticollision sequence to separate several tags in the same antenna field.

13,56 MHz Multitag Reader Module, Version 0.9v ACG Identification Technologies AT Page 8 3.3.3 My-D Label (SRF55VxxP) My-D labels are specific labels of Infineon. These labels show a different memory organization. Two different modes of tags are supported: plain and secure mode. At the moment only plain mode tags are supported in full functionality. Only serial numbers are supported in secure mode. Two different cards with 320 bytes or 1k bytes EEPROM memory are available. The EEPROM memory is divided into pages. Each tag is split into two parts: The administrative blocks (00h, 01h, 02h) and the user area. Administrative pages are read only and cannot be changed. User data is free for use. Additionally user data pages can be locked. This procedure is irreversible. The EEPROM of SRF55V10P is organized in 128 pages addressed 00h to 7Fh. The EEPROM of SRF55V02P consists of 32 pages addressed 00h to 1Fh.

13,56 MHz Multitag Reader Module, Version 0.9v ACG Identification Technologies AT Page 23 5.3.3.8 Start page (10h) The EEPROM register defines the start page address in page read mode. To enable this function the page read flag has to be set. See above protocol configuration register. The reader will send the content of this page instead of the serial number. This mode is only supported for ISO15693, Icode® and Tagit® tags. The reader does not check the integrity of the page address. If an error occurs or a not valid page is read nothing is returned. Default value is 00h. 5.3.3.9 Number of pages (12h) The number of pages describes how many following pages are read. The start address is specified at EEPROM register 10h. The reader returns all pages and sends in the end a <CR> + <LF>. In binary protocol mode each page is send separately. No terminator is sent in the end. Value 00h is reserved and should not be used. Default value is 01h (one page is read). 5.3.3.10 User data (20h-FFh) User data is free for use.

13,56 MHz Multitag Reader Module, Version 0.9v ACG Identification Technologies AT Page 25 5.3.6 Continuous Read The reader device reads and displays the serial numbers continuously while one or more tags remain in the field. This command stops if any character is sent to the reader module. The reader module returns the character ‘S’ (53h). Only different tag types are detected at the same time. Use the multitag list command (see chapter 5.3.8) if more than one ISO15693 tag are present. The reader supports different tag types. Though a single continuous read instruction needs a specific time. To increase the reading performance switch to a single tag mode. Results depend on the startup conditions. See chapter read EEPROM register for more details of startup configurations. 5.3.6.1 Command Command Data ‘c’ none 5.3.6.2 Answer Answer Description data Leading character (1 byte) + serial number (n bytes) Number of bytes depends on tag type. This command is not supported in binary protocol mode. 5.3.6.3 Leading character The leading character specifies a single tag type. It can be used to determine the present tag type and control tag specific commands. Card types have different UID length, e.g. ISO15693 cards use an 8 byte UID whereas standard ISO14443 Type A cards 4. Following table describes all leading characters of supported tag types. Tag type UID length Description ‘V’ 8 bytes ISO 15693 ‘T’ 4 bytes Tagit® ‘I’ 8 bytes Icode® ‘M’ Var. size Mifare® Ultralight, ISO 14443 Type A ‘S’ 8 bytes SR176 ‘Z’ 4 bytes ISO1443 Type B Figure 5-12: Leading character of continuous read mode

This speeds up the communication to a tag in continuous read mode. The reader only uses this tag type anymore. 5.3.6.6 Extended ID (default disabled) If set Tagit® and ISO14443 Type B cards returns additional information. Tag type Number of Bytes Description Tagit® 2 page size, number of pages ISO14443B 7 Application data, Protocol Identifier Figure 5-13: Extended ID 5.3.6.7 SingleShot function (default disabled) If enabled the reader replies the serial number only once. Then the reader waits until a timeout is reached. One time slice is around 100 ms. The timeout value has the range of one byte and is stored in EEPROM register 0Fh. 5.3.6.8 PageRead function (default disabled) If enabled the reader sends a page content instead of the serial number back to the host. The reader starts at the page specified in the EEPROM register 11h and reads as many as following pages defined at EEPROM register 12h. A single command is terminated with an <CR> + <LF>. In binary protocol mode each page is transmitted separately. At the end no <CR> + <LF> is transmitted. 5.3.6.9 LED function (default disabled) Using the LED active flag the reader suppresses an activity of the LED. The user can set the LED state using the commands of switching on/off LED. 5.3.6.10 Simple access control applications Serial numbers are not encrypted and always sent plain to the reader. This results in a low-level security application.
13,56 MHz Multitag Reader Module, Version 0.9v ACG Identification Technologies AT Page 27 5.3.7 Select This command selects a single card in the antenna field. It can only be used in single tag mode.

In the end the amount of detect tags are returned. A Multi Tag list command resets all tags in the antenna field. 5.3.8.4 Reading distance Each card needs a specific amount of power. The reader always provides the same power. Therefore the reading distance will decrease if more tags are present. 5.3.8.5 Multi tag select Using the eight-byte serial number as parameter the according tag will be selected. High-level interactions can be performed addressing only this card. All other tags are still present but not used. 5.3.8.6 Maximum number of tags The maximum number of tags in the antenna field is limited to the physical characteristics of the antenna. Internally the software can handle up to 40 tags (theoretical maximum). 5.3.8.7 Example Command Description m<CR> VE000123456789012 –> first card VE000112233445566 –> second card 02 –> number of detect tags mE000123456789012 E000123456789012 Select card with its serial number

All you need is a PC, a connection cable and a power supply for the reader. If you are using Microsoft Windows (98/NT/2000…), take following steps: 1. Make sure, that your reader is RS232-interface type 1. Start HyperTerminal 2. Create a new connection (FILE/NEW CONNECTION) 3. Enter name of connection as you like (i.e. ‘ISO 1.0’) 4. Select connect COM2 (COM1) direct connection 5. Connection setup 9600,8,n,1,no handshake 6. Connect the reader to COM2 (COM1) of the PC and apply appropriate the supply voltage. The reader sends a string to the PC (e.g. “ISO 1.0”). This string denotes the firmware provided by your reader module 7. Put a tag to your reader. Serial numbers should be displayed properly 8. Enter commands via keyboard. They are transmitted to the reader and the reader replies with its response. If using an operating system different from Microsoft Windows you may use any other terminal program which is capable of receiving/transmitting via the serial port of your PC. 7.2 How can I adjust the reading performance of different tags? Due to different tags of different tag manufacturers the antenna tuning has to be adapted. The Plug and Play reader module is factory tuned for ISO 15693 tags. To switch to Mifare tags the tuning capacitor (see APPENDIX A) has to be adjusted correctly. Following steps have to be done: 1. Connect the reader to the PC 2. Set the reader to the specific tag type 3. Start continuous reading mode (‘c’) 4. Place a tag within the antenna field. 5. Tune the capacitor until the LED is flickering. 6. Increase the distance between the tag and the reader 7. Repeat steps 5 and 6 until no better performance can be reached. Now the reader is optimal tuned of a specific tag type. 7.2.1 Remarks If more than one tag has to be read all steps mentioned above have to be performed for each tag type. The reading distance of one tag in multi tag recognition mode might be less than in an optimal tuned antenna field.
