 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 (contact information at the beginning of this manual) 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:
 If you have installed an SV-GPS-250, 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
SkyView display, make the same serial port connections to ALL SkyView displays. If you are
using the SV-GPS-250 GPS Receiver module, make sure that power and ground wires are
also installed correctly.
 Ensure that the GPS serial port’s parameters are configured correctly. Go to the Serial Port
Setup Menu (SETUP MENU > SYSTEM SETUP > SERIAL PORT SETUP > SERIAL PORT # SETUP)
and check the input device, function, baud rate, and output device properties of the port.
This menu also contains serial transmit (TX) and receive (RX) counters. These show activity
on the transmit and receive lines of that port and can indicate if the GPS is at least active on
that port. Reference the SV-GPS-250 Serial Connection Section for SV-GPS-250 serial port
settings. Also reference the Serial Devices Section on page 4-11 of this guide if a
comprehensive explanation of SkyView serial connections is necessary.
Engine Sensor Does Not Show Up Onscreen
Make sure the sensor is installed, defined, mapped, and configured according to the
instructions found in the SV-EMS-220/221 Installation and Configuration Chapter.
MAP Button Is No Longer Available
SkyView displays are shipped with a 30 Flight Hour trial of the SkyView Map. After 30 Flight
Hours have elapsed (the trial has expired), the next time SkyView is powered up, the MAP
button will not appear. If you wish to continue using SkyView’s Map functions, see SV-MAP-270
Navigation Mapping Software Purchase and Setup.
