(c) ATL Agricultural Technology Ltdwww.agricultural-technology.co.uk Modifications During the approval testing of the Pegasus Active Triple Field Antenna system modifications were made at the test house to ensure compliance. These are detailed below: 1. Mains input filter was moved so that it is placed next to the mains input connector. This ensures a minimal length of wiring between the connector and filter inside the main control enclosure. 2. The screens of the coaxial antenna cables as they enter the control box enclosure were strapped to the enclosure wall with a clamp close to the antenna connector. This ensures the electrical integrity of the enclosure. 3. The use of a good quality screened lead for the RS232-C data connection between the externally mounted interface port and any connected data collector or computer. This cable would be supplied by the end user and a note stating this will be included in the user manual that accompanies the device. These modifications are detailed in the relevant product production documents. The modifications noted in items 1 and 2 will be implemented in all production units Robin Sadler Managing Director

(c) ATL Agricultural Technology Ltdwww.agricultural-technology.co.uk Operational Description System Overview The system is used as an electronic tag reading system for animal identification purposes on farms, markets/sales and abattoirs. This design is used for identifying cattle whilst they move along passageways. Each animal to be identified must be tagged with a low frequency half-duplex transponder. These are usually in the form of ear tags. The system comprises a ‘walkthrough antenna and a control box. The antenna is a cubic structure made from either galvanised or stainless steel tubes. This antenna structure houses three pairs of transmit/receive loop antennae. These are connected to the control box via coaxial cables. The control box is a stainless steel enclosure housing a power supply circuit, the TIRIS tag reader module and the antenna multiplex circuit. The box also has connections for line voltage and communications data. During operation a tagged animal walks through the antenna. The reader module transmits a carrier to the tag which uses this signal to charge an internal capacitor. When sufficient charge is built up, the tag responds to the reader module with a unique identity code. The reader module then decodes this and outputs it via the RS232-C communications interface. This can then be captured by a computer. System Breakdown The complete system comprises four individual blocks of circuitry. The operation of each of these blocks is described below: Power Supply The line voltage of 115VAC is first filtered and fused. It is then transformed to 15 volts by a 50 VA isolation transformer. The 15 volts AC is then rectified and smoothed before being regulated to a steady 13.6 volts DC. (for the reader module). TIRIS Reader Module The reader module is a commercially available tag reading system from Texas Instruments. It works on a half duplex system whereby it continually switches between transmit and receive modes. The transmission burst at 134.2KHz lasts for 50 ms. This is followed by a receive period of 20mS and then a wait/sync period of 20mS. The transmission is used as a charge burst to charge the animal tag’s internal storage capacitor. When charged, the tag responds, by which time the reader has switched to receive mode. The tag responds with 134.2KHz signal that is frequency modulated with a unique identity code using frequency shift keying (fsk) with a bandwidth of 20KHz. The reader has an RS232-C communications interface port used to transfer the tag code to an external computer. The reader has two status indicators that are mounted on the front panel of the control box. The red LED flashes on whenever the reader goes into transmit mode. Under normal operation this LED flashes at a rate of approx. ten a second. The green LED flashes once for each successful tag read. The antenna pairs are matched to the reader output by the addition of the parallel tuning coil. The coil has an adjustable ferrite slug that enables each system to be individually tuned to give maximum performance. (c) ATL Agricultural Technology Ltdwww.agricultural-technology.co.uk Multiplex Circuit The single antenna output from the reader module must be switched continually between the three pairs of antennas. This is done by taking the ACTIVE pulse signal from the reader module and dividing it by three using a divider logic chip. These three sequential outputs are then used to sequentially turn on three separate opto-isolated MOSFET switches. Each of these MOSFETs switches a pair of antennas. The opto MOSFETs are paired in parallel to cut down on signal losses. Antenna The antenna consists of three pairs of parallel loops. Each of the pairs is switched on in turn via the multiplex circuit and the opto MOSFETs. This ensures that whichever orientation the tag is in it will be read by at least one pair of antennas.
(c) ATL Agricultural Technology Ltdwww.agricultural-technology.co.uk Tuning Information The system works at a fixed frequency that cannot be changed. The only tuning available ensures that the inductance of the antenna system matches the output of the reader module. This tuning is achieved with an adjustable inductor connected into the circuitry between the reader and the antenna. The antennas and controls are manufactured and tested separately, so they are not shipped as a matched pair. This means that during installation the control must be tuned to match the attached antenna to give the best performance. The antennas and controls are all built to within a small tolerance and the tuning required will be minimal. A volt meter is required to tune the control system. The volt meter, on the 200 volt DC range is connected to the each of the test pins on the left hand side of the multiplex module in turn. The antenna must be attached to the system and the mains turned on. Tuning is done by slowly turning the tuning inductor control knob on the tuning inductor either clockwise or anti clockwise until the average voltage on each of the test pins is a maximum. A tag can then be used to test the system to ensure reading is adequate. Three tests can be carried out to verify the performance: 1. Approach the antenna either from the side or end with the transponder held so that it is aligned with the axis of the side or end being approached. The distance from the antenna at which the tag is first read should be about 600mm (2ft). 2. Hold a transponder at the mid point of the side just inside rail with the transponder oriented front to back. The ‘no read’ window should be relatively small, no more than a triangle 100mm along and 100mm inwards at the centre point of the side rails. 3. Hold a transponder tag at the centre of the antenna framework. It should be possible to rotate the transponder in all directions whilst it is being read. At an angle of 45 degrees to each of the three antenna pairs it should be read continuously by all three antenna pairs. This is indicated by a rapid, even flashing of the read OK LED.

The system is intended to detect tags on cattle which pass through a steel frame. Loop antennae are incorporated in the frame. A control unit feeds the antenna with a 134.2kHz signal. The results of the detection system may be output to a PC via a serial port. The device was therefore considered as an intentional radiator operating under the rules of CFR 47 subsection C and also a digital device under CFR 47 subsection B. The class B limits for a digital device were applied (although the higher class A limits may be considered more appropriate for the system). Two versions of the system were tested. The only difference between the units was the material used to make the frame which housed the antennae. One version was stainless steel, the other galvanised mild steel. The same controller was used for both units. Details of the EUT and associated peripherals used during the tests are listed below. Figure 1 shows the interconnections between the EUT and peripherals.
