<\/span><\/div><\/div>

What is included in the OpenVario kit?<\/strong><\/h3>\n
    \n
  • 5,7\u2033 or 7\u2033 housing<\/li>\n
  • 5,7\u2033 or 7\u2033 display<\/li>\n

    The sensor board is optional and not included in the scope of delivery of the OpenVario. An alternative to the sensorboard is LARUS, which can also be connected to the OpenVario. LARUS offers a high-end variometer for the dedicated cross country and competition pilot as well as real-time wind calculation.<\/p>\n<\/div><\/div><\/div><\/div>

        Step 1: Mounting Adapterboard & Cubieboard<\/h3>\n

        Parts required:<\/p>\n

          \n
        • 4 x long M3 screws<\/li>\n
        • 4 x plastic spacers<\/li>\n
        • Adapterboard with Cubieboard<\/li>\n
        • 4 x M3 distance bolts<\/li>\n<\/ul>\n
          \n

          Please note: Using threadlocking adhesive is not necessary. If you want to apply threadlocking adhesive, please use only low-strength versions like Loctite 221. Otherwise, disassembling is hardly possible!<\/p>\n<\/blockquote>\n<\/div><\/div><\/div>

          <\/span><\/div><\/div><\/div>
          <\/span><\/div><\/div>

          Step 1.1: Mounting Adapterboard & Cubieboard<\/h3>\n

          Note:<\/strong> Please have a look at Step 6<\/em>: In step 1.1 you should already attach the cable shielding (black wire with ring connector) of the display cable.<\/p>\n

          Mount the Adapterboard to the Cubieboard like shown in the picture. Be cautious when you need to readjust the distance between Adapterboard (green) and Cubieboard (black). Only apply force in the area of the pinheaders, so that you don\u00b4t bend the thin Cubieboard too much.<\/em><\/p>\n<\/div><\/div><\/div><\/div>

          Step 1.2: Mounting Adapterboard & Cubieboard<\/h3>\n

          Mount the distance bolts and spacers as shown.<\/p>\n<\/div><\/div><\/div>

          <\/span><\/div><\/div><\/div>
          <\/span><\/div><\/div>

          Step 2.1: Serial cable between Adapterboard & Cubieboard<\/h3>\n
          \n

          Bitte beachten: Die Schritte 2.1 - 2.3 k\u00f6nnen \u00fcbersprungen werden. Serielle Kabel sind aus Vereinfachungsgr\u00fcnden nicht mehr Bestandteil des Bausatzes.<\/p>\n<\/blockquote>\n

          Parts required:<\/p>\n

            \n
          • Adapterboard & Cubieboard<\/li>\n
          • 2 pin serial cable<\/li>\n<\/ul>\n

            Now you can attache the 2 pin serial cable between the Adapterboard & Cubieboard.<\/p>\n

            The Cubieboard has a pinheader with 4 pins, but we only use the RX and TX pin. Attache the cable to the RX and TX pin.<\/p>\n

            If you don\u00b4t install the serial cable, you still have 3 serial ports on the OpenVario for external devices. And at the moment, ttyS0 (UART 1) is only configured for debugging purpose. <\/em><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div>

            Step 2.2: Serial cable between Adapterboard & Cubieboard<\/h3>\n

            Now flip the package, so that the Adapterboard is on top. There you will find a 2 pin pinheader, which is located in the middle of the Adapterboard. Connect the cable here, so that you don\u00b4t twist the cables. In this example the yellow cable is on the side of the USB port. The colour of the cable can be different in your OpenVario kit.<\/p>\n<\/div><\/div><\/div>

            Step 2.3: Serial cable between Adapterboard & Cubieboard<\/h3>\n

            You can wind the serial cable around the distance bolt like shown in the picture.<\/p>\n<\/div><\/div><\/div><\/div>

            Step 3: Sensorboard installation (optional)<\/h3>\n

            Parts required:<\/p>\n

              \n
            • Sensorboard<\/li>\n
            • 3 x hose connectors<\/li>\n
            • Sensorboard cable<\/li>\n
            • Back housing of the OpenVario<\/li>\n<\/ul>\n

              Install the Sensorboard cable on the IDC header of the Sensorboard like shown in the picture.<\/p>\n<\/div><\/div><\/div>

              <\/span><\/div><\/div><\/div>
              <\/span><\/div><\/div>

              Step 3.1: Sensorboard sealing<\/h3>\n
              \n

              Please note: Sealing of the hose connectors of the sensorboard is highly recommended to ensure the air-tightness.<\/p>\n<\/blockquote>\n

              Take some Sikaflex 221 or similar silicone free sealant<\/em> and put it on the threads of the three hose connectors. Be careful not to use too much, otherwise it will squeeze out and can close the pressure hole.<\/p>\n<\/div><\/div><\/div><\/div>

              Step 3.2: Sensorboard sealing <\/h3>\n

              Now you can carefully insert the Sensorboard into the housing. Look at the correct alignment before you fasten the hose connectors.<\/p>\n<\/div><\/div><\/div>
