RFI341 Radio Frequency Interrogator19 SICK AG − Division Auto Ident - Germany - All rights reserved 8012640/2008-03-103.2 Functional Description of the deviceThe device operates according the reader/interrogator “talks first” (ITF)method as defined in the ISO/IEC 15693 Standard. Each transponder inthe field remains silent until a request is received. The interrogator canidentify simultaneously a number of tags present in the antenna field. Theinterrogator can write data to and read data from the transponders.Transponders can be addressed by e.g. using the factory programmed,unique read only number (64 bit length). If the data in the user memory ofthe tag are not write protected, the read/write feature enables therewriting of the data stored in this memory.The RFI341 is controlled by the data interface. The commands aredescribed in the document “Telegram Listing RFI341” which enables theuse of the features defined in ISO/IEC 15693. Additional commandssupport the use of sensor inputs and/or actuators. After configuration thedevice could either work in a mode where the host in controlling the unitor in trigger mode. Configuration in trigger mode means: The device iswaiting for a start condition to start reading automatically. Reading resultswill be transmitted directly or with closing the read window. If the deviceis running in background mode only a valid escape sequence willterminate this and brings the device back in command mode (see alsotelegram listing).To start a reading process, when an object with a transponder is in thefield, the RFI341 must be clocked by one of the following:• A command sequence via the data interface• The execution (based on a suitable trigger) of a previouslydefined background commandIf a transponder is detected, the relevant data can be send via the datainterface to the host. The “Data LED” indicates the presence of tag data.Product Description

Troubleshooting8.1 Installation errorsThe RFA3xx antenna is installed incorrectly with respect to the objectcarrying the transponder, e.g., the relationship between the transmittedpower, antenna size and transponder form factor is unfavourable.• The RFA3xx antenna is installed close to metal that de-tunes the antenna circuit. This can be checked either bythe SWR measurement inside the device. To start thisthe background function need to be interrupted. Thanthe SWR bottom need to be switched. The LED barindicates the SWR status. In addition a beeper signalswith frequency the status (high frequency is good, lowfrequency is bad). Tuning is possible by inside antennatunable capacitors.• The trigger sensor is positioned incorrectly.• Other interrogator antennas are causing interference.8.2 Electrical Connection Errors• Interfaces on the RFI341 are connected incorrectly.8.3 Parameterisation Errors• Functions are not adjusted to local conditions, e.g., communicationparameters for the host interface are set incorrectly.• ISO or system settings are not in accordance with the transpondersused, e.g., wrong AFI used..Troubleshooting

The Part3, Mode 1 is compatible with ISO/IEC 15693.This summary should be used only as a basis for understanding the featuresgiven by the ISO/IEC15693 standard. The full documentation can be orderedfrom ISO/IEC.
RFI341 Radio Frequency Interrogator42 SICK AG − Division Auto Ident - Germany - All rights reserved 8012640/2008-03-10ISO/IEC 15693-2 Air Interface and InitialisationThis part of ISO/IEC 15693 describes the electrical characteristics of thecontactless interface between the transponder and the interrogator. Theinterface includes power and bi-directional communications.Initial Dialog for ISO15693 Transponder• Activating of the transponder (interrogator RF power on)• Transponder waiting for a command from the interrogator (ITF)• Receiving the command from the interrogator• Transmitting the response to the interrogatorPower TransferThe power transfer from the interrogator antenna to the transponder isaccomplished by radio frequency via coupling antennas. The RF operatingfield that supplies power to the transponder from the interrogator ismodulated for communication.FrequencyThe transponder frequency is 13.56 MHz ± 7 kHzCommunications Signal InterfaceFor some parameters, special modes are available to comply with differentinternational radio regulations and application requirements.ModulationCommunications between interrogator and transponders takes place usingthe ASK modulation principle. If the modulation index is set to 100 %, thenoise sensitivity is less. A modulation index of, e.g., 20 % will increase theread/write performance but also increase the noise sensitivity.Data Rate and Data EncodingThe transponder support two data coding modes(1 out of 4 at 26.48 kbit/sec and 1 out of 256 at 1.65 kbit/sec).
RFI341 Radio Frequency Interrogator43 SICK AG − Division Auto Ident - Germany - All rights reserved 8012640/2008-03-10ISO/IEC 15693-3 Anticollision and Transmission ProtocolThis part of ISO/IEC 15693 describes the anticollision and transmissionprotocols.The anticollision is based on a UID that each tag supports. The length of thisID is 64 bits and it is guaranteed by the manufacture of the IC that the ID isuniqueAFIThe Application Field Identifier (AFI) should – if available – represent theapplication for which the transponder is used. It can be programmed andlocked within the transponder with the commands given in the document“Telegram Listing RFI341”.The AFI consists of 8 bits. If no applicablepreselection is possible, use “0h”..The support of the AFI feature is optional. That means it is possible that ISO15693 compliant transponders do not offer this AFI feature. It is recommendthat only those transponders that offer this AFI byte be used.Therefore, check carefully the selection of the transponder IC type and therequirements given by the application.DSFIDThe Data Storage Format Identifier (DSFID, 8 bit) can be used to indicate inwhich manner the user data is structured in the user memory. If no DSFID isused, this value should be “0h”.AnticollisionThe purpose of the anticollision is to make an inventory of the transponderspresent in the field by using their UIDs.The anticollision is based on slots. The interrogator can use one or sixteenslots. If the interrogator wants to ensure that tags are present for ananticollision or knows that only one transponder is present in the field, theslot length of one is adequate.If additional transponders are in the field, the interrogator will detect this by aerroneous CRC.If more than one tag is in the field and the interrogator uses the 16 slots,each transponder will calculate a number (with help from UID) between 1and 16 and replies in a special slot. It can occur that more than one tagreplies in the same slot.
RFI341 Radio Frequency Interrogator44 SICK AG − Division Auto Ident - Germany - All rights reserved 8012640/2008-03-10In this case, the interrogator will skip to the next slot. Within the nextinventory session, these transponders will participate whereas those thathave been successfully read (UID) could be not present – depending on thefunction, which may set these transponders to the quiet stage. This processcould be repeated until all transponders are identified. Tags colliding in a slotcould be separated with masks according to ISO Standard.Command CodesThe ISO 15693 requires that only two commands to be mandatory in an IC.These are “Inventory and Stay quiet”. All other commands are defined butoptional.Therefore, ensure that the tag used supports the application requirements.These include:• Read and write feature• Lock block feature• Read and write of multiple blocks• AFI and DSFID features
