(range, MPG, etc) on the fuel page and GPS information only (track, ground-speed, course, etc)
on the HSI page. There is no need to break this connection when doing PC updates.
IF YOU OWN AN EMS AND AN EFIS (NOT FLIGHTDEK-D180)
First, ensure that your EMS and EFIS are connected as described in Dynon Smart Avionics Bus
(DSAB) Wiring on page 3-11.
If you only have either the GPS or SL30 (but not both), connect the GPS or SL30 transmit line to
pin 19 on the EMS DB37 connector. This is labeled “Aux Serial Receive.” With either a GPS or
an SL30 connected, you are able to display an HSI on either product; with a GPS connected, you
are able to display EMS fuel economy displays.
If you have a GPS and an SL30, connect the GPS to pin 19 on the EMS DB37 connector.
Connect the SL30 to pin 22 on the EFIS DB25 connector. This will allow you to flip between
GPS and SL30 inputs. You can use either the SL30 or GPS as the NAV source on the EFIS
product. You will need to disconnect the SL30 from the EFIS when doing software updates.
IF YOU OWN ONLY A FLIGHTDEK-D180
Connect the SL30 unit to pin 22 on the EFIS DB25 connector, and the GPS to pin 19 on the
EMS DB37 connector. You can display either source on the HSI using the softkeys. You will
need to disconnect the SL30 from the EFIS when doing software updates.
IF YOU OWN A FLIGHTDEK-D180 AND AN EFIS
Connect the SL30 unit to pin 22 on the FlightDEK’s EFIS connector (vertical DB25) and the
GPS to pin 19 on the EMS DB37 connector. You can display either source on the HSI, and you
can display either on the standalone EFIS as well (provided you have connected the DSAB A &
B lines from the FlightDEK-D180 to the standalone EFIS product). You will need to disconnect
the SL30 from the FlightDEK-D180 when doing software updates.
Do not connect any serial devices to the secondary EFIS device. It will only display data from
the serial devices connected to the master FlightDEK-D180.
