Complete the auto-networking procedure (described on the yellow instruction sheet) at deck level and ensure that Wind Speed and Angle are being displayed on the instruments. 2. Get an authorised dealer to ascend the mast and carefully mark and drill the three mounting holes using the supplied Template. Care should be taken to ensure the Template is positioned facing forward. 3. Secure the Wind Transmitter to the masthead using the three self tapping screws provided. NOTE: It may be necessary to use alternative mounting screws or bolts depending on the masthead plate. 4. Check for smooth and free operation of the anemometer cups and the windvane feather before de scending to deck level. WARNING: Always ensure that you are secured correctly before ascending any mast. Always attach a safety strap to the masthead whilst you are working and leave a competent person on deck to assist. If in doubt get a professional to ascend the mast. What Next Refer to the instrument handbook for details on calibration and alignment. Installation Method 1.

Tacktick Limited T120 Wind Operational Description Introduction This document is to be read in conjunction with the ‘Tacktick Limited T120 Wind Block Diagram’. The functionality of each block shown on the diagram is expanded in this document. Microprocessor This device stores the operating software in its on board flash and system data in its on board RAM. The software controls the operation of the T120 Wind Transmitter. The software can be upgraded in circuit by connecting the programming port to a PC running the appropriate development environment. The microprocessor uses a precision voltage reference against which to measure inputs through its built in 8 channel ADC. An external supervisor chip is used to ensure that the microprocessor is reset if it fails to produce a periodic strobe signal. Batteries and Recharging Circuit The unit runs from two internal, rechargeable lithium coin cells. These cells can be recharged using the integral solar cells. Magnetic Wind Direction Measurement Circuit The microprocessor provides an output signal that excites the wind direction measurement circuit. This circuit interacts with a permanent magnet in the rotating vane on top of the unit. The direction measurement circuit produces signals that are read through ADC inputs on the microprocessor. This data is used to determine the current angle of the wind vane. Optical Wind Speed Measurement Circuit The microprocessor drives an optical sensor that counts the rotations of a printed disk that is connected to the rotor cups on the wind transducer. The return signals from the sensor are counted by the microprocessor and the data is used to determine the current rotation speed of the cups. Radio Transceiver Circuit and PCB Antenna The unit communicates with other units in the network across a wireless data link. The microprocessor sends configuration sentences to the radio transceiver chip. The data link between the microprocessor and the radio chip is half duplex. The RF signals are transmitted / received using a simple monopole wire antenna.

Identification Of Equipment Under Test (EUT) Brand Name: Micronet mn100 Model Name or Number: T120 Wind Transmitter Serial Number: 0401/00002 (for sample used to perform transmit measurements) 0307/00498 (for sample used to perform receive measurements) FCC ID RX9-T120-916 Country of Manufacture: UK Date of Receipt: 29 January 2004 2.2. Description Of EUT The equipment under test is a low power radio networked leisure marine instrumentation wind speed and direction transmitter. 2.3. Modifications Incorporated In EUT For the purposes of testing only (i.e. to allow testing of transmitter parameters to be performed), a sample of the EUT was software modified to increase the ‘transmit on’ time to 250 mS every second from the normal (and very low) operating mode duty cycle ‘transmit on’ time. Additionally the EUT was modified to provide a direct connection point to the internal 3V rails (post charging circuit) for an external 3V DC power supply. This was necessary to allow the EUT to operate at this increased transmission rate as the internal battery supply (which is recharged by solar panels) is not rated for this extended transmission rate and would discharge very quickly i.e. the EUT would no longer operate in this test mode.
