3 RFID Systems
As 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

4 System Description
This 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 reading 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 divides 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.

5 Quick Start
First 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.

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 Interfaces
For 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 microprocessor. 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 Ethernet
The 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 configured 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: admin
Password: scemtec
The 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 connector 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.

Manual SIL-2125 v0.8
6.2.2 USB
The 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 Interface
The 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 Function
TxD 2 Transmit Data
RxD 3 Receive Data
GND 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 Function
TxD2 8 Transmit Data Secondary RS232
RxD2 7 Receive Data Secondary RS232
GND 5 Ground
Special Adapters cables for connecting external devices to the secondary RS232 are available from
STT.
6.3 HF Unit
The 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
Page 11
Manual SIL-2125 v0.8
6.4 External Antenna
The 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 transponder 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 Versions
The Reader is available in two versions. The standard version is equipped with a Splitter, which divides 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 connectors, SMA-BNC or SMA-N Adapters are available from STT.
