    SPORT Installation Manual GRT Avionics facilitate installation and removal of the display unit, quick disconnect fittings may be helpful. Connections and the entire pitot-static system must be leak tight. Refer to AC 43.13-2B for approved methods to achieve this. Consider placing a water trap or drain in the lowest part of the pitot-static system to prevent water from getting into the electronics.

  • Page 21: General Guidelines

    GRT Avionics SPORT Installation Manual SECTION 3: WIRING CONSIDERATIONS General Guidelines Wires that are certain to be used are pre-installed in the EFIS cable assembly connectors. Optional connections to the EFIS are not installed in the D-sub connectors at the factory, however, colored aviation-grade wires with pre-installed D-sub connector contacts are included for these connections.

  • Page 22: Ground Connections

    SPORT Installation Manual GRT Avionics No provision is included within the display units for a power switch. If a power switch is desired for the EFIS, the +12V power should be controlled with the switch (not ground). The display units include internal thermally-activated fuses. This protects the equipment from internal electrical faults.

    At least one GPS should be connected to the EFIS. Only one GPS source (internal or external, can be assigned to GPS1, and only one GPS source may be assigned to GPS2.) Sport SX Internal GPS Settings The internal GPS provides serial data at 9600 baud in the NMEA0183B format. The output from this GPS is wired to pin 32, may be shared with all GRT EFIS display units as desired, as well as at least two other devices, such as an ELT, transponder, etc.

This can occur if the magnetometer X, Y, Z inputs are swapped. To check for this, point the airplane at various directions listed in the table below, with the magnetometer in an approximately level position (it may need to be removed from the airplane and held by hand).

  • Page 30: Magnetometer Calibration Procedure

    SPORT Installation Manual GRT Avionics Magnetometer Calibration Procedure The magnetometer must be calibrated before the first flight of the aircraft. Magnetometer calibration is required to achieve accurate magnetic heading readings. This calibration corrects for errors induced by magnetic disturbances local to the sensor, such as ferrous metal objects.
  • Page 31 SPORT Installation Manual GRT Avionics airplane must be rotated completely through 360 degrees, plus an additional 20 degrees past magnetic north, within 3 minutes after initiating the calibration. The airplane should be rotated slowly, such that it takes approximately 60 seconds for the complete rotation.

  • Page 35 Providing EFIS Internal GPS Data/Active Waypoint to External Devices: Sport SX - When equipped with the optional internal GPS, serial input 3 is wired within the EFIS to its internal GPS. This will cause serial output data to be present on this EFIS serial input, which may be wired to other devices that require GPS data.
  • Page 36 SPORT Installation Manual GRT Avionics Optional Dual Serial Inputs to Autopilot: A switch may be installed to allow coupling the autopilot to the GPS in the event the display unit that normally controls the autopilot is not functional. This switch is wired to select between the EFIS autopilot output and the GPS serial data output. This switch should remain in the EFIS position unless the display unit that provides the autopilot output is not functional.
