If possible, make a cutout with a CNC equipment. You can use the dxf file to program the CNC.
Nesis III — Installation Manual 2.4 Mounting Procedure Green line is coutout line. A tolerance of 0.4 mm was already added. No extra tolerance is needed. Dashed line represents bezel outer contoure. 211,1 Drill 3.5 mm hole to fit M3 screw.
Nesis III — Installation Manual 2.4 Mounting Procedure 2.4.1 Fixation with Supplied M3 nut and Lock Washer This is the most straightforward method of fixation. Figure 5 shows an ex- ample. Figure 5: An example of fixation using supplied M3 nut and lock washer.
Nesis III — Installation Manual 2.4 Mounting Procedure Once pressed, the nut shall not turn when Nesis is removed and this makes servicing easier. The hole size needs to be as accurate as possible. It is recommended to do a few tests on a scrap part first.

, which protects against voltage spikes. A coil in relays without this diode may cause spikes that exceed 100 V and they propagate on the system bus. Such spikes may cause permanent damage on Kanardia equipment and other avionics. Backup Battery This backup battery solution works only on 12V systems.

Nesis III — Installation Manual 6. Audio and Video Audio and Video Nesis can be connected to the audio system (audio out) and video (video in). These two have nothing in common – audio and video are not associated. Audio connection is used to allow Nesis to send out some audio messages, mostly warnings, which can be then heard in the headset.

No actions are required on the Nesis side. Nesis has two CAN bus port. The CAN bus is the main communication bus between Kanardia devices. The CAN bus is a very robust vehicle bus. The communication is message based and connected devices communicate without the host computer.
Nesis III — Installation Manual 8.1 Connector and Plug Connector and Plug We are using standard Ethernet computer cable with RJ45 connector on each side. Communication leads are central twisted pair leads – pins 4 and 5, while other pins are used as a power supply for connected devices.

Nesis III — Installation Manual 11.2 Parameters 11.2 Parameters The Parameters window is used to set and tune name, range and color limits for different parameters used by Nesis. Figure 51 shows the options. Figure 51: Various options for parameter settings.
Nesis III — Installation Manual 11.2 Parameters Select a layout and Nesis will erase/reset all existing parameters and load parameters from the layout instead. If selected layout does not have any parameters defined, the command is ignored. 11.2.1 Parameter Editing Selection of an item from the Edit section starts parameter editing.
Nesis III — Installation Manual 11.3 Flap Settings Tiny defines a tiny version of parameter name. It must remain tiny, one or two letter max. It is used where short name does not fit. Color bands define the parameter scale color marking limits. Illustration of the parameter limits is given in the right part of the window.
Nesis III — Installation Manual 11.4 Trim Sensitivity Time of travel defines approximate time of flap from 0 to 100%. This value is used with combination of flap position sensor to detect the flap move- ment and also to prevent sporadic flap movement messages.
Nesis III — Installation Manual 11.6 Serial Ports Only these two formats are supported. Please check which format is producing your camera and set it accordingly. 11.6 Serial Ports Nesis has several serial (RS-232) multi purpose ports at the back. Please refer to the section 10 starting on page 38 for details.
Nesis III — Installation Manual 11.9 Restore 11.9 Restore This command restores backup files from a USB memory stick. The files must be create with a backup process first. The files are expected to be located in Nesis-Backup folder. If only one such folder exists on the USB memory stick, then restore process is automatic.
Nesis III — Installation Manual 12.1 Yaw Misalignment Figure 55: AHRS Leveling window. 12.1 Yaw Misalignment When the instrument panel is perfectly flat and perpendicular to the airplane x-axis (longitudinal axis) than there is no yaw misalignment and the correction angle is zero.
Nesis III — Installation Manual 12.2 Roll and Pitch Adjustment Yaw correction affects the roll and pitch correction as well. Hence it is im- portant to set yaw before roll and pitch adjustments are made. 12.2 Roll and Pitch Adjustment Once yaw correction is known (in most cases it is zero), roll and pitch can be adjusted automatically.

Nesis III — Installation Manual 13.3 Channels Figure 59: An example of channel Z editing. Z is typically used for the engine RPM. Filter defines a low level filtering. This is a low pass filter time constant. A larger value means that more time is needed for a measurement to react on some sensor change.

Nesis III — Installation Manual 14.1 Fuel Level Sensors 14.1 Fuel Level Sensors After the fuel level sensor channel has been set for certain fuel tank, the tank must be calibrated properly. In principle, this is similar to the Min/Max procedure for trim sensors.
Nesis III — Installation Manual 14.1 Fuel Level Sensors Figure 65: An example of linear fuel tank. Typically, the tank is completely drained and a value shown by the fuel level sensor is copied to the Empty. Then, the tank is filled with fuel and the sensor value is copied to the Full.

Nesis III — Installation Manual 14.1 Fuel Level Sensors were needed for a sensor to react. So, the real tank capacity is 46 liters, but Nesis will show values between 0 and 42. Figure 67b shows the final situation. The dark blue color line on the chart shows tank non-linearity.
Nesis III — Installation Manual 14.2 Simulated Fuel Tank 4. Close the window. The tank shape has now been defined and scaled to the min and max sensor position. Predefined shapes also support the Edit option, where individual points can be adjusted.
Nesis III — Installation Manual 15. Offset Offset Some sensors and counters may require occasional adjustment. The offset window allow adjustment for static and dynamic pressure sensors, CO sensor, fuel flow correction and time counters adjustments. Please make sure that Nesis is running for at least 10 min before any sensor adjustments are made.

Increasing the factor will also increase the calculated fuel consumption. Use software based fuel flow with great care. The indications may be incorrect and this indication will also impact the software based fuel tank, range and endurance, when used.
