Appendix A: Maintenance and Troubleshooting
SkyView HDX System Installation Manual - Revision E 23-15
• Ensure the SkyView network status includes the ADAHRS you’re trying to
calibrate. Use the Network Status Wizard and confirm that the ADAHRS is
present in the system.
• Ensure the ADAHRS location is compatible with the requirements outlined in
Section 7 SV-ADAHRS-200 ADAHRS Installation and Configuration of this
manual, especially the discussion of external magnetic interference.
23.10.4 Display does not Turn On
If your SkyView display does not turn on, try the following:
• Check power wiring and fuses and try again. There may be a short or an open
somewhere.
• Observe the lights on the Ethernet port. Unlike other Ethernet ports, these lights
are used for display status:
o Yellow light on: Power on pins 1/20 (power/ground).
o Yellow light off: Display not receiving power.
o Green light flashing: Normal when display is turned on, or turned off with a
SV-BAT-320 connected.
o Green light solid on or off: Something is wrong with the SkyView display.
Contact Dynon Avionics Technical Support (contact information at the
beginning of this manual) for further support.
23.10.5 No GPS
GPS is an essential part of a SkyView system. If you do not have a working GPS, you
cannot set the system time, calibrate the compass, or use the moving map. If you are
experiencing these symptoms, try the following:
• If you have installed an SV-GPS-2020, its SERIAL IN FUNCTION must be set
to POS 1.
• Check wiring and connections. Make sure all wiring runs are complete, that
connections are solid, and that transmit (TX) and receive (RX) are not
swapped. If you have more than one (1) SkyView display, make the same
serial port connections to ALL SkyView displays. If you are using the SV-
GPS-2020 GPS Receiver, make sure that power and ground wires are also
installed correctly.
