UTB-100 TX Tuning Guide LUCATRON AG CH-8606 Greifensee, Switzerland Version 1.0 Page 3 1. Introduction This manual describes the UTB-100 (Universal Transmitter Board) as well as the setup and tuning procedures needed to put the UTB-100 and URB-100 electronics into operation. For details on the receiver board, see the RX Tuning Guide. 1.1. Basic Description of the Transmitter Electronics Each transmitter electronics is able to feed one LUCATRON antenna with a swept HF signal of 8.2 MHz. In order to avoid disturbances between the emitted HF signals, synchronization with other transmitters must be guaranteed. The standard version of the UTB-100 board allows the 82 Hz sinusoidal modulated 8.2 MHz HF carrier signal to be: −−−− generated locally (oscillator circuit for master applications), or alternatively. −−−− to be regenerated from an optically received swept HF signal of another TX (opto receiver for slave applications). The bi-opto version of the UTB-100 additionally allows the onboard generated (master) or received-and-then-regenerated- (slave)-swept HF-signal to be converted and optically transmitted in order to synchronize additional transmitters. The two opto transmitters used in the bi-opto version allow: −−−− a master transmitter to synchronize two other optically slaved (and possibly repeating) transmitters. −−−− an optically slaved transmitter to be used as repeater to synchronize two other optically slaved transmitters. By using 3 bi-opto transmitter boards (TX) (one used as synchronization master and two as synchronization repeaters) and 4 standard TX (as synchronization slaves), clusters of up to 7 TX may be synchronized. This way up to 7 checkout or 14 exit-gates (in a row) may be configured without need of a master rack. Since the optically transmitted synchronization signal may be repeated only once, a master rack still has to be used if more than seven transmitters have to be synchronized. A block diagram and layout of the UTB-100 board are shown on the next 2 pages. The board consists of a digital part, an analog part and a power supply / filter part. The standard version of the UTB-100 is fully equipped with the exception of the two optional opto transmitters. It can be used as a master-TX for small installations (single or dual gates equipped with one TX only) or as slave-TX for all larger applications. The bi-opto version of the UTB-100 board is almost identical to the standard version. The only difference is that the two opto transmitters (IR-LED's) are already mounted. The bi-opto TX board can be used as a master-TX in medium installations (2 to 7 TX) or as synchronization signal repeating slave-TX for medium to very large installations. INTRODUCTION

UTB-100 TX Tuning Guide LUCATRON AG CH-8606 Greifensee, Switzerland Version 1.0 Page 6 1.1.1. Digital Part In master operation, the 82 Hz sinusoidal sweep is fed to the voltage controlled oscillator (VCO). The VCO generates the swept and digitalized 8.2 MHz signal. This frequency modulated signal is digitally amplified (FET power amplifier), filtered to get a clean analog output signal and finally radiated by the antenna. lf the current exceeds the allowed limit (short circuits, wrong antenna etc.) the power amplifier will shut slowly down, because it is temperature controlled. This action is indicated by a red LED (overloaded = OFF). In slave operation, the swept HF signal is optically received, converted and regenerated. It can then be used to directly feed the power amplifier. A set of jumpers (J2 and J3) is used to switch between master and slave operation. Jumper J4 is used to select the desired sweep frequency. lf the board is equipped with two opto transmitters (bi-opto TX board), the swept HF signal will be automatically output (see section 4). This allows the synchronization of two additional transmitters. 1.1.2. Analog Part Different antenna types can to be connected to the relevant output circuit (connector X4). The TX-mounted matching circuits and harmonic suppression filters are optimized for use with 200 Ohm antennas. The UTB-100 is not designed to drive other types of antennas. All equipment and system guarantees will be lost and all field support will be charged if other types of antennas are used without written approval of LUCATRON. 1.1.3. Power Supply / Filter Part The UTB-100 can be powered (connector X1 / IN) by DC as well as AC power supplies. The integrated power line filters: −−−− suppress noise between the electronics and the power line and −−−− suppress conducted noise on the power line itself. The filtered power is available at connector X2 / OUT and can be used to feed other equipment (TX, RX). For additional information, see section 2, UTB-100 Filter Concept. 1.2. Receiver Electronics For detailed information on the receiver, see RX Tuning Guide. INTRODUCTION
UTB-100 TX Tuning Guide LUCATRON AG CH-8606 Greifensee, Switzerland Version 1.0 Page 7 2. UTB-100 Filter Concept False alarms due to conducted noise on the power lines can be avoided if the power lines are filtered every 4 to 6 meters. If UTB-100’s are used, this is done automatically and the power line between the transmitters is not longer than 6 (8.2 MHz) meters. lf the length of the power cable between the transmitters is longer than 4 to 6 meters, additional filter boards have to be used (see figure below). LUCATRON RX boards use the same kind of filter. Due to the limited space available, however, the RX filter only protects the receiver electronics itself, it doesn't contribute to the filtering of the power line.

Deactivator DAV-100 Synchronization In a “Checkout System Installation” the deactivator DAV-100 can be synchronized by cable. 3.1. Cable Synchronization A twisted cable must be connected between the TX Board and the Deactivator Electronic. The cable must be as short as possible, not longer than 3 meters (see figures below). To prevent resonance, ferrites must be mounted on the Synchronization Cable.

Installation Configurations Since the UTB-100 can be used as a synchronization master, repeater or slave, installations can be flexibly configured. Basically there exists only one rule that has to be considered: The optically transmitted synchronization signal may be repeated only once; therefore no synchronization repeater should ever feed another repeater. A basic configuration following this rule is shown below. The TX board of level 1 (bi-opto version, configured as master) feeds the synchronization signal to the two TX boards of level 2 (bi-opto version, configured as slave).

UTB-100 TX Tuning Guide LUCATRON AG CH-8606 Greifensee, Switzerland Version 1.0 Page 11 These two boards, acting as synchronization repeaters, in turn each feed their optically transmitted signal to two following TX boards of level 3 (standard version, configured as slave). This way, a synchronization cluster of 7 transmitters has been created without use of a master rack. lf a system consists of more than seven transmitters, a master rack has to be used as a synchronization source. The optical signal of a master rack may be repeated once if necessary as well. A possible configuration using a master rack and UTB-100 is shown below.

Power On Adjustments • Power ON the TX board (insert PWR connector at socket X1). • Check the red Temp-Limit LED (H102) is ON: Operation OK. • lf the LED is going OFF and ON: −−−− reduce the emitted power with the amplitude potentiometer R147. −−−− exchange TX board. −−−− check antenna, matching board for short circuit and so on. • As an option, check the emitted signal at both of the corresponding test points located to the left and right of the antenna connector (P4 / GND and P5 / GND; see figure below). The signal shapes may be varying. A signal breakdown or variation of more than 20% of average the value indicates a faulty transmitter or antenna.
