Manual SIL-2125 v0.8 1 Safety InformationsAs with all electronic systems, the system described hereafter may not be used for any applications critical for maintaining safety. This means, the products may not used in life sup-port applications or any other life critical applications that could involve potential risk of death, personal injury or severe property or environmental damage.The user/operator is solely responsible for any damages resulting from an improper or unin-tended utilization of the system.Page 3 of 23

Manual SIL-2125 v0.8 3 RFID SystemsAs this technology is based on radio frequency, one must exercise the following operational and mounting instructions to achieve best performance:•Metal affects radio signals. Normally the antenna has to be as far away as possible from any metal object and it’s damping influence on the magnetic field. Only this leads to the best distribution of the magnetic field in the reading range. Very important as well is not to have “short circuits”, in the vicinity of the antenna, damping the magnetic field. A “short circuit” is any metal near the antenna, building a “metallic ring”, so that currents introduced by the RF-field can flow, absorbing the energy needed for the tag to operate. •Care must be taken to reduce or eliminate unwanted signals (so called interference or noise) from external sources. The reading range may be reduced by following noise sources: •portable two way radio•cellular phones•switching power supplies•computer monitors•frequency converters (e.g. motor control systems) •The read range is depending upon•performance of the Reader•size of the antenna•size of the tag (the bigger the better)•orientation of the tag antenna plane to the Reader antenna plane•quality of the tag•matching of Reader antenna size and tag (-antenna) size•environmental, electrical noise•If influence of metal can not be fully avoided a tuning of the antenna is required and will improve reading range Page 5 of 23

Manual SIL-2125 v0.8 4 System DescriptionThis manual describes the 13,56 MHz Long Rang Reader System „SIL-2125“, hereafter referred to as "Reader".The 13,56 MHz Long Range Reader system „SIL-2125“ is designed as a multi-tag system for read-ing and writing information stored on transponders (TAGs). It is primarily designed to be operated with so called Gate-antennas. Therefore a splitter is integrated in the standard version, which di-vides the output-power generated by output stage symmetrically to two BNC antenna connectors. Nevertheless the standard version can be configured to operate with only one antenna attached to Antenna Port ANT1 with slightly reduced output power.Beside this a MUX Version with integrated antenna multiplexer is available. This version offers 4/8 antenna ports with SMA connectors for attaching external antennas.The Reader is designed for indoor usage only.Transfer of data between the Reader and a host computer is possible via Ethernet, USB and an asynchronous RS232 interface. Furthermore a configurable “stand-alone” operation via so called Smart Read Feature is possible. The Reader is compatible with the ISO/IEC 15693-2 and ISO 18000/3 “A” and “C” standards.Page 6 of 23

Manual SIL-2125 v0.8 5 Quick StartFirst Connect the Reader as shown below:As example you can use the STT antenna “SAT-A40-LR-O-13MHz” [400.4020].Now you can use a Software like “Uni - Demo” to control the Reader. For more details please refer to “Quick Start Guide read”. This Guide is available for download on www.stt-rfid.com.Page 7 of 23figure 1: Reader connection example

Manual SIL-2125 v0.8 6 Hardware 6.1 Voltage Supply The Reader is designed for a voltage supply connectible via an standard 2.1-mm barrel connector.Polarity of connector The reader may only be connected to a power supply with a maximum output current of 2 A, which is tested for safety according to appropriate standard (e.g. EN60950)A suitable wall plug power supply is available as optional accessory. For best performance and safety, STT strongly recommends to use only this power supply 6.2 InterfacesFor communication with a host device (e.g. PC), the Reader provides three interfaces (RS232, USB, Ethernet). The interfaces are handled by an separate, built-in interface unit with an ARM7 micro-processor. This interface-unit can also be configured to operate the Reader in stand-alone mode (Smart Read feature).The interfaces are intended to be used only with connection cables not longer than 3m. 6.2.1 EthernetThe Reader is equipped with a 10/100 T-Ethernet interface.By default the Reader gets his IP Address via DHCP. Nevertheless the Reader can also be con-figured with a static IP Address. Configuration can be done via a simple integrated web server, which can be reached by typing the actual IP Address in the address line of browser. After Login, configuration page for of Network settings is available. Default Login Settings:Username: adminPassword: scemtecThe actual assigned IP address of the reader can be determined using STT Demo Software (e.g. Unidemo). Clicking the “Search” Button in Ethernet connection window of the STX/ETX connect-or will show the actual IP address as well as MAC address of all STT devices available in the local network. Network settings may also be configured by using STX-ETX commands. For details please refer to STX-ETX protocol description. Page 8 of 23

Manual SIL-2125 v0.8 6.2.2 USBThe Reader is equipped with a USB 2.0 full speed (12 Mbits/sec) port. The connection is made via a standard USB-B connector.Supported profiles CDC-ACM (virtual COM-Port), HID (Keyboard emulation) Appropriate drivers for Windows are available for download on www.stt-rfid.com. 6.2.3 RS 232 InterfaceThe Reader is equipped with a RS232 interface. The connection is made via a standard 9 pin D-Sub connector . Terminal designation: SUB-D Connector Pin Terminal FunctionTxD 2 Transmit DataRxD 3 Receive DataGND 5 Ground The data transfer rate is adjustable via STX-ETX commands.Configuration 8 Data Bits, 1 Stop Bit, no Parity, no flow control Supported Data Rates [baud] 1200, 2400, 4800, 9600 (default), 19200, 38400 57600, 115200, 230400 In addition to the primary RS232 Interface described above, the Reader provides a secondary RS 232 Interface, intended to be used in stand alone mode as interface for connecting auxillary equipment (e.g. additional RFID reader, bar code scanner, …). The connection to the secondary RS232 ist also made via the 9 pin SUB D connector. Please contact STT for further Information regarding usage of the second RS232 in your application.Terminal designation: SUB-D Connector Pin Terminal FunctionTxD2 8 Transmit Data Secondary RS232RxD2 7 Receive Data Secondary RS232GND 5 Ground Special Adapters cables for connecting external devices to the secondary RS232 are available from STT. 6.3 HF UnitThe carrier frequency of 13.56 MHz is generated in the HF unit. The final stage generates an output of typical 10 watt on nominal ZF = 50 Ohm.Page 9 of 23

Manual SIL-2125 v0.8 6.4 External AntennaThe Reader is only operational with external antenna(s). Some key parameters of the Reader such as reading range for example depends on the used antenna, the used transponder type,size and quality, and the resulting magnetic coupling between the trans-ponder resonant circuit and the transmission/receiver antenna.The connected antenna(s) should be configured for the optimal resonance frequency of 13.56MHz with ohmic adjustment (nominal ZF = 50 Ohm) to ensure the best possible system performance.When using antennas not provided by STT, please make sure that the antenna quality factor is in the range between 20 and 50 and the antenna is optimally tuned. The resulting SWR value should be well below 2.Antenna tuning should be checked at the final installation. Furthermore antenna detuning caused by heating of the antenna matching unit should also be observed 6.5 Reader VersionsThe Reader is available in two versions. The standard version is equipped with a Splitter, which di-vides the output power to two antenna ports for operating two antennas simultaneously.Beside this a version with integrated antenna Multiplexer (MUX) is available, which switches the output power to one of up to 4 or 8 antenna ports, for sequential operating of attached antennas. 6.5.1 Internal Splitter (standard)For using the standard version of the Reader with two antennas (e.g. a Gate antenna) the Split-mode is available. In this mode the built in splitter divides this power symmetrically to the two antenna connectors. So typical 5 watt on nominal ZF = 50 Ohm is available at each of the two antenna BNC connectors. For using the Reader with a single antenna setup, a Single-mode is available. In this mode a slightly reduced HF power of typ. 7,5 Watt on nominal ZF = 50 Ohm is only available on antenna port ANT 1. The desired operation mode can be selected via a software command. Furthermore the output power can be reduced by software commands in both operation modes. 6.5.2 Internal Multiplexer In this version up to 4/8 antennas (Depending on the stage of expansion of the integrated MUX) can be connected to the Reader. The user can select each connected antennas with software commands. In this version a slightly reduced HF power of typ. 7,5 Watt on nominal ZF = 50 Ohm is available on the selected antenna port at any one time.Furthermore the output power can be reduced by software command. The MUX Version is equipped with SMA antenna connectors. For using with BNC or N connect-ors, SMA-BNC or SMA-N Adapters are available from STT.Page 10 of 23
