Assembly RFI341 Radio Frequency Interrogator Distance Between the RFI341 and the Host The RFI341 can be installed with a maximum data cable length depended on the used interface and the chosen data rate (see chapter 5.4.1) Distance Between the RFI341 and the RFA321 Antennas The RFI341 can be installed at a maximum distance given by the antenna cable length. Increasing the cable length will have an impact to the operating performance. 4.2.
Electrical Installation RFI341 Radio Frequency Interrogator 5. Electrical Installation 5.1 Overview of the Installation Steps • Connect the RFI341 with the Antenna • Connect the sensors to the RFI341 inputs (if used) • Connect the actuators to the RFI341 outputs (if used) • Connect the PC or Profibus data interface of the RFI341 • Connect the power supply to the RFI341 5.
RFI341 Radio Frequency Interrogator 5.3 Electrical Connections (M12 connectivity version) The M12 Connectivity Version consist out of one PG plug for e.g. Ethernet and M12 plugs for power, RS232, Output and 2 for the Trigger Input. The individual pinning could be found on a sticker that is placed inside the device door. 5.4 Preparations for Electrical Installation 5.4.1 Requirements for the RS-232 HOST interface The host interface can be operated as a RS 232 data interface.
Electrical Installation RFI341 Radio Frequency Interrogator 5.4.3 Main Power supply The main power supply is 24V DC with a max input current of less than 2 Ampere (<50W). The power cable need to be shielded if the length extend 3m. The Shield need to be connected with the “Function earth”. Power-up Delay After the RFI341 is powered, the device will do an internal diagnostic. After the diagnostic is finished the interrogator sends the start-up message or will execute the background mode.
Electrical Installation RFI341 Radio Frequency Interrogator 5.4.5 Connecting the “Input 1” Switching Input If a reading procedure of the RFI341 shall be triggered by an external sensor, then the reading pulse sensor must be connected, e.g., to the Input 1 switching input. The triggering feature is set by the background function as described in the document “Telegram Listing RFI341”. The GND1 is galvanically separated. Therefore the reference for the Input 1 level must be provided by the customer.
RFI341 Radio Frequency Interrogator 5.4.6 Connecting the Switching Output The two switching outputs are completely user defined and controlled by special command strings as described in the document “Telegram Listing RFI341”. The maximum load current is 400 mA. The outputs are driven with supply power (24V DC norminal). The output drivers are powered with the DC input voltage of nominal 24V DC and with the Dc power supply reference.

RFI341 Radio Frequency Interrogator 5.6.3 Connect the RS232 Interface If the RS-232 interface is intended to be use, e.g for parameterisation with the SICK software, it needs to be ensured that the Profibus interface interface is disabled (switch at the CMF, see CMF documentation). 5.6.4 Connect the Profi-Bus Interface If the Profibus interface should be used than the terminals needs to be connected. Dependent of the position in a network the terminal resistors need to be removed.
Operation RFI341 Radio Frequency Interrogator 6. Operation 6.1 Overview of the Start-up Steps • Start the RFI341 with the default settings (Quick start) • Connect to the PC or HOST • Use the Demo/Parameterisation-Software to run the device or • Control the device by using the related command strings or • Configure (parameterise) the RFI341 for the desired application 6.2 Factory Default Settings The table below shows the factory setting of the RFI341.
Operation RFI341 Radio Frequency Interrogator 6.3 Configuration (Parameterisation) The RFI341 is configured locally in accordance with the existing application. The read, evaluation and output characteristic, can be parameterised as required. The factory default settings or the application specific parameter set is in affect before changes are made. The RFI341 can be configured by using either the PC Demo Software or the specific commands sent by the user host software. 6.3.
Operation RFI341 Radio Frequency Interrogator 6.3.3 Oscillator Switch off delay Switching off the HF-field results in a power-on reset of all tags present in the reader field. The length of time set should be checked very carefully. In the worse case scenario, the tags which are in the selected or quiet mode will loose this status. Depending on the application, it could be necessary to set this time to a lower value. The factory default setting is 500 ms. 6.3.
Operation RFI341 Radio Frequency Interrogator 6.4 ISO/IEC 15693 settings The ISO/IEC 15693 Standard allows various settings. To configure correctly for the specific application, it is recommended that the user have a basic understanding of the features described in this standard. Supported functions are: • Changing of the forward link modulation depth. The factory default setting is 20/100 % • Changing of the return link modulation type (ASK/FSK). The factory default setting is FSK.
Maintanance RFI341 Radio Frequency Interrogator 7. Maintanance 7.1 Maintenance The RFI341 does not require maintenance. 7.2 Disposal Irreparable devices or devices that are no longer required are to be disposed of in an environmentally-friendly manner: 1. Always observe the applicable national waste disposal regulations. 2. Remove the RFI341 housing. 3. Remove the electronic modules and the connection cables. 4. Send the metal housing to be recycled. 5.
Troubleshooting RFI341 Radio Frequency Interrogator 8. Troubleshooting 8.1 Installation errors The RFA3xx antenna is installed incorrectly with respect to the object carrying the transponder, e.g., the relationship between the transmitted power, antenna size and transponder form factor is unfavourable. • The RFA3xx antenna is installed close to metal that detunes the antenna circuit. This can be checked either by the SWR measurement inside the device.

RFI341 Radio Frequency Interrogator ISO/IEC 15693-2 Air Interface and Initialisation This part of ISO/IEC 15693 describes the electrical characteristics of the contactless interface between the transponder and the interrogator. The interface includes power and bi-directional communications.
RFI341 Radio Frequency Interrogator ISO/IEC 15693-3 Anticollision and Transmission Protocol This part of ISO/IEC 15693 describes the anticollision and transmission protocols. The anticollision is based on a UID that each tag supports. The length of this ID is 64 bits and it is guaranteed by the manufacture of the IC that the ID is unique AFI The Application Field Identifier (AFI) should – if available – represent the application for which the transponder is used.
RFI341 Radio Frequency Interrogator In this case, the interrogator will skip to the next slot. Within the next inventory session, these transponders will participate whereas those that have been successfully read (UID) could be not present – depending on the function, which may set these transponders to the quiet stage. This process could be repeated until all transponders are identified. Tags colliding in a slot could be separated with masks according to ISO Standard.
