
Install the GEAR contact that when the amphibious landing gear is configured for landing on
water, the state of the contact is WATR and when the amphibious landing gear is configured
for landing on land, the state of the contact is LAND.

General Purpose Thermocouple
You may configure the SV-EMS-220 to monitor two J or K type thermocouples in addition to the
twelve thermocouples available on the SV-EMS-220’s D25 connector. Note that the SV-EMS-221
uses these four pins for Rotax 912 is communication, and, therefore, these pins are not
available for thermocouple use on the SV-EMS-221. Dynon Avionics does not supply a specific
general purpose thermocouple probe for this purpose. However, our standard EGT and CHT
probes will work, as will any other J or K type thermocouple.
The following table revisits which SV-EMS-220 pins are compatible with general purpose
thermocouples.
Pin Wire Color Function
27 Not supplied General Purpose TC Input 1+
28 Not supplied General Purpose TC Input 1-
36 Blue General Purpose TC Input 2+
37 Green General Purpose TC Input 2-
Table 43 – SV-EMS-220 D37 General Purpose Thermocouple Pins
If you use the second general purpose thermocouple input on pins 36 and 37, it is
necessary to remove the blue and green wires from these pins on the EMS 37-pin
Main Sensor Harness.
Dynon Avionics sells both J and K type thermocouple wire which may be used to connect the
desired thermocouple to the SkyView. Ensure you order the correct wire type for the
thermocouple you intend to use. Crimp a female D-sub pin on the end of each wire, and plug
them into the SV-EMS-220’s EMS 37-pin Main Sensor Harness D37. Polarity is important, so
ensure that you are routing the positive side (yellow for K-type; white for J-type) of the
thermocouple to pin 27 or pin 36 on the 37-pin harness, and the negative side to pin 28 or pin
37.
