DYNON EMS Serial Data Format
The following section details the format of EMS data output to the serial port:
3 = EMS Data. Other Dynon formats look
similar, and may be interleaved, this bit
indicates what kind of data will follow.
Currently 2. This is the version of the data
represented below and will change if there
is a future version that changes data. Data
version changed at SkyView version 5.1.
HHMMSSFF, current Zulu time according to
SkyView's internal clock which is
synchronized with GPS time if GPS is
available. HH is the hour from 00 to 23.
MM is the minute from 00 to 59. SS is the
second from 00 to 59. HHMMSS are '--------'
if GPS time has never been available. FF is
the 1/16-second fraction counter from 00
to 15, and may skip digits if baud rate is too
low to send data at 16Hz.
000 to 999 or XXX. Oil pressure in
PSI. There must be a pressure sensor
named "OIL" for this to work. See note 2.
+/- then 000 to 999 or XXX. Oil
temperature in C. There must be a
temperature sensor named "OIL" for this to
work. See note 2.
0 to 9999. RPM from Left input.
0 to 9999. RPM from Right input.
0 to 600. Manifold Pressure in 0.1 inHg.
299 = 29.9 inHg. There must be a pressure
sensor named "MAP" for this to work. See
note 2.
000 to 999. Fuel flow in 1/10th Gallons Per
Hour. 086 = 8.6 GPH. See note 2.
000 to 999. Fuel flow in 1/10th Gallons Per
Hour. 086 = 8.6 GPH. This is usually return
flow. See note 2.
