KLN313ALow Power Communications Transmitter

Installation Instructions I. Introduction Thank you for purchasing a Maximum Wireless Weather instrument. Maximum Wireless Instruments are designed with the customer in mind. Ease of installation and operation enable the “Do It Yourselfer” to install these instruments. If you need assistance, consult a contractor, electrician, or satellite dish installer. II. Components Receiver Wind Tx Temperature Tx Rain Tx III. Test Wiring It is important to pre-wire and test operation from different locations prior to final installation. A. Receivers 1. Merlin and/or Mystic - Connect the AC power wires from the Receiver (Red and Green wires) to the AC power terminals (polarity does not matter) on either Merlin or Mystic instrument (Do Not apply power). - Connect the White wire from the Receiver to terminal #1 (In) of the same instrument. - Connect the Black wire from the Receiver to terminal #2 (GND) of the same instrument. - The Yellow and Brown wires are used only if you are installing a Rainwatch. - If both Merlin and Mystic are being installed, use the jumper wire enclosed with Mystic for connection between these two instruments. o Connect one end of the White wire to terminal #3 (Out) of the instrument wired to the Receiver, and the Black wire to terminal #2 (GND). o Connect the other end of the White wire to terminal #1 (In) of the second Instrument, and the Black wire to terminal #2 (GND). A. Receivers (cont.) 2. Rainwatch - Connect the Yellow wire from the receiver to terminal #4 of the Rainwatch. - Connect the Brown wire from the receiver to terminal #5 of the Rainwatch. B. Transmitters 1. Temperature - The Temperature transmitter operates on two AA Alkaline batteries (supplied). o Do Not install the batteries yet. - Open the thumb-latch on the Temperature transmitter case, and place the circuit board Jumper in the test position (see Diagram A). This will ensure that the Receiver recognizes the Temperature transmitter when batteries are eventually installed. Jumper Normal Position Test Position Diagram A 2. Rain Transmitter - The Rainfall transmitter operates on two AA Alkaline batteries (supplied). o Do Not install the batteries yet. - Remove the top of the Rain Collector by loosening the four Phillips head screws and rotating the top counter-clockwise. - Remove the blue cover to access the circuit board, and place the circuit board Jumper in the test position (see Diagram B). This will ensure that the Receiver recognizes the Rainfall transmitter when batteries are eventually installed. Jumper Normal Position Test Position Diagram B 3. Wind Transmitter - Insert two AA NiCad batteries (supplied) into the enclosed battery charger (be sure to observe Polarity) and charge batteries for 12 hours. o Note: Do not attempt to charge batteries other than NiCad batteries, as they could explode, causing physical damage and/or fire. - Feed the terminal lug end of the Yellow and Brown wires through one of the rubber boots and connect the lugs to the terminals on the bottom of the wind speed sensor using the brass nuts provided. The polarity does not matter. o Note: Do Not adjust the nuts that are already on the sensor. - Feed the terminal lug ends of the remaining 5 wires through the other rubber boot and connect to the terminals on the bottom of the wind direction sensor using the brass nuts provided. o Connect the 5 wires to the wind direction sensor as follows: ß White wire to Terminal 1 ß Orange wire to Terminal 2 ß Black wire to Terminal 3 ß Red wire to Terminal 4 ß Green wire to Terminal 5 o Note: Do Not adjust the nuts that are already on the sensor. - Slide the straight stub mast through the rubber boot and insert it into the bottom of the wind speed sensor. Secure the sensor to the mast with the supplied cotter pin. - Slide the formed (“Z” shaped) stub mast through the other rubber boot and insert it into the bottom of the wind direction sensor with the #3 terminal aligned over the mast arm. Secure the sensor to the mast with the supplied cotter pin. o Note: If the sensor is not installed with the #3 terminal aligned over the mast arm, wind direction readings will be incorrect. SIDE COMPONENT ES00057B 3. Wind Transmitter (cont.) - Remove the bottom portion of the black bracket on the back of the Wind transmitter case, by loosening the four black screws. - Place the Wind transmitter case on the horizontal section of the formed wind direction mast with the antenna situated above the mast arm. - Place the bottom portion of the black bracket behind the mast arm and secure it in place with the four black screws that were removed. - Secure both sensor stub masts to your antenna mast (not supplied) with the two hose clamps provided. - Open the Wind transmitter case by lifting the two thumb latches, and place the circuit board Jumper in the test position (see Diagram C). This will ensure that the Receiver recognizes the Wind transmitter when batteries are eventually inserted. Jumper Normal Position Test Position Diagram C IV. Transceiver Testing & Sensor Installation (please follow directions in the order shown) A. Instrument Display - Move the instrument display and the individual sensors nearby the desired installation location (the display may lie on a table or floor for testing purposes). o This step is necessary to determine whether or not proper signals can be obtained for each component, prior to final installation. - Connect the AC adaptor(s) provided, to the instrument(s). o If you have more than 1 instrument, wire 1 AC adaptor to each instrument. - Plug in all the AC adaptors. SOLDER SIDE A. Instrument Display (cont.) - The following should display on each instrument upon power-up: o Merlin: all LEDs will illuminate, then “0” will display in the window and the North LED will light. o Mystic: all LEDs will illuminate, then a barometer reading will display in the window. o Rainwatch: “00.00” will display in the window. o Cronus: all LEDs will illuminate, then current time will display in the win…

The product covered by this report is the WAIR. It is a low power communications transmitter and receiver operating at 916.5MHz. Test Methodology Radiated emissions testing was performed according to the procedures specified in ANSI C63.4 (2003). The EUT was maximized around one axis, as the EUT can only be installed in one position. The EUT has an integrated internal antenna which can not be maximized separately. The EUT is battery powered with no provision to be connected to the AC mains. The standard test voltage was 3V dc provided by two AA alkaline batteries. The ambient environmental conditions were as follows: Date Temperature Humidity 4/21/06 23.9°C 22% Frequency range investigated: 30 MHz- 10 GHz Measurement Distance: Frequency (MHz) Distance (m) Comments Fundamental 916.5MHz 3 m Radiated Spurious & Harmonics 30 – 10000MHz 3 m Radiated All readings are peak unless otherwise noted. For frequencies below 1000MHz, a RBW of120kHz and a VBW of 300kHz were used. For frequencies above 1000MHz, a RBW of 1MHz and a VBW of 3MHz were used.
