15-8 SkyView System Installation Guide - Revision K
o Flashing Fast: The module is operating normally and is configured and
communicating on a SkyView Network.
o Flashing Slowly: The module is operating normally, but is not active on SkyView
Network.
o Off: The module is not receiving power (from a SkyView Network / Display)
o On Solid - the module is receiving power, but is not operating normally.
Compass Calibration Fails
If you try to calibrate your compass and it does not work, try the following:
Ensure SkyView is receiving data from the system’s GPS receiver. Go to the Display
Hardware Information Page as mentioned at the beginning of this section, scroll down
the menu to the serial port status section, and confirm that the receive (RX) counter is
active on the GPS serial port.
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 the
General System Installation Tips Section of this guide.
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
backup battery connected.
o Green light solid on or off: Something is wrong with the SkyView display. Contact
Dynon Technical Support for further support.
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:
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 are using the
SV-GPS-250 GPS Receiver module, make sure that power and ground wires are also
installed correctly.
