Table 85 – Dynon EMS Serial Output Format
Note 1: These sensors can be connected to various pins on the EMS 37-pin D-sub connector
(D37). See the SkyView Installation Guide for more information.
Note 2: If the value is invalid, or out of range for the sensor, or the sensor is not configured, or
if the sensor is configured but not calibrated, then an 'X' is output for each character in the field
instead of a value.
Note 3: Units for each GP input depends on the type of sensor that is connected to the pin.
See GP Inputs
Rotax 912 iS Note: When the engine type is 912iS, the following fields in the serial output
source their data from the 912 iS’s computer instead of conventional sensors: Oil Pressure, Oil
Temp, RPM L, RPM R, Manifold Pressure, Fuel Flow 1, Fuel Flow 2 (always 0).
GP Inputs
The output for GP input pins is:
 Each output is in the format +YYYYZ
o + is the +/- sign for the value
o YYYY is the value of the signal
o Z is the units for the signal
 C if the signal is in temperature, and the units are 1/10th degrees C
 YYYY is 1/10th degrees C, so 1234 = 123.4 C
 XXXX if the signal is out of range (red X on ems page)
 ZZZZ if the input is not configured
 P if the signal is in pressure, and the units are 1/10 PSI
 YYYY is 1/10th PSI, so 0123 = 12.3 PSI
 XXXX if the signal is out of range (red X on ems page)
