DYNON SYSTEM Serial Data Format
The following section details the format of DYNON SYSTEM serial output data:
Position Width Name Description
1 1 Start Character '!'
2 1 Data Type
2 = System Info. Other Dynon formats look
similar, and may be interleaved, this bit indicates
what kind of data will follow.
3 1 Data Version
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.
4 8 System Time
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.
12 3 Heading Bug (deg)
000 to 359 in degrees. XXX if heading bug is not
displayed.
15 5 Altitude Bug (ft)
+/- then 0000 to 9999, altitude in units of tens of
feet (1234 = 12,340 ft). XXXXX if altitude bug is
not displayed.
20 4
Airspeed Bug
(knots)
0000 to 9999, airspeed in units of knots *
10 (1234 = 123.4 knots). XXXX if airspeed bug is
not displayed.
24 4
Vertical Speed Bug
(ft/min)
+/- then 000 to 999, tens of feet/minute. (123 =
1230 ft/min), positive meaning climb. XXXX if
vertical speed bug is not displayed.
28 3 Course (deg) 000 to 359 in degrees.
31 1 CDI Source Type 0-2. 0=GPS, 1=NAV, 2=LOC.
32 1 CDI Source Port 0-5. GPSX, NAVX, or LOCX.
33 2 CDI Scale (NM)
00-50. In tenths of NM, 50 = 5.0 NM. Output 'XX'
when not in GPS mode as there is no scale in NAV
or LOC
35 3 CDI Deflection (%)
+/- then 00 to 99 percent of deflection, +
meaning deflected to right, 'XXX' w/o valid CDI.
38 3 Glideslope (%)
+/- then 00 to 99 percent of deflection, +
meaning deflected upward, 'XXX' w/o valid GS.
