Appendix E: Serial Data OutputDYNON SYSTEM Serial Data FormatThe following section details the format of DYNON SYSTEM serial output data:Position Width Name Description1 1 Start Character '!'2 1 Data Type2 = System Info. Other Dynon formats looksimilar, and may be interleaved, this bit tells youwhat kind of data will follow.3 1 Data VersionCurrently 2. This is the version of the datarepresented below and will change if there is afuture version that changes data. Data versionchanged at SkyView version 5.1.4 8 System TimeHHMMSSFF, current Zulu time according toSkyView's internal clock which is synchronizedwith GPS time if GPS is available. HH is the hourfrom 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 the1/16-second fraction counter from 00 to 15, andmay skip digits if baud rate is too low to senddata at 16Hz.12 3 Heading Bug (deg)000 to 359 in degrees. XXX if heading bug is notdisplayed.15 5 Altitude Bug (ft)+/- then 0000 to 9999, altitude in units of tens offeet (1234 = 12,340 ft). XXXXX if altitude bug isnot displayed.20 40000 to 9999, airspeed in units of knots *Airspeed Bug10 (1234 = 123.4 knots). XXXX if airspeed bug is(knots)not displayed.24 4Vertical Speed Bug(ft/min)+/- then 000 to 999, tens of feet/minute. (123 =1230 ft/min), positive meaning climb. XXXX ifvertical 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)35 3 CDI Deflection (%)38 3 Glideslope (%)00-50. In tenths of NM, 50 = 5.0 NM. Output 'XX'when not in GPS mode as there is no scale in NAVor LOC+/- then 00 to 99 percent of deflection, +meaning deflected to right, 'XXX' w/o valid CDI.+/- then 00 to 99 percent of deflection, +meaning deflected upward, 'XXX' w/o valid GS.21-4 SkyView System Installation Guide - Revision O
