    Tachometer input voltages

    This is a forum for Dynon Engine Monitoring Systems. Nothing to do with Rotec Electronic Ignition. Maybe here? https://forum.rotecaerosport.com/forum/main-forum/r3600/57-electronic-ignition

    CHT cooldown alarm

    Does that mean shock cooling alarms can be turned off in the D120 then? How? Given how many glider tugs crack at the base flanges of their cylinders, and how few other aircraft do so, there might be something to shock cooling... I knew someone who drove his overheating VW Golf (Rabbit) into a...

    Shunt and ammeter?

    Why? No backup battery? Over-voltage on the other hand... Don't ask me how I know!

    D180 ASI error troubleshooting

    Compare with a 'steam' instrument?  ;) I'm in the UK hence forced to have to have a steam backup to the EFIS for ASI, ALT and Compass so it's easy for me to suggest this. This does mean a static or pitot line leak or position error will render both measurements out by the same amount, but at...

    connecting an eternal GPS to the EFIS D10A

    Far be it from me to disagree with the official line... ... so I won't.  ;) I'll just add that most of the time (GNS430 / 530 excepted) the GPS supplies the current date and time for the screen display (if used) and in the logs. The alternative method to keep/set the current time is to have to...

    GPS connection to D100 / D120

    That seems to have sorted it. Cut down on the number of NMEA sentences the 296 squirts down the serial lines.

    GPS connection to D100 / D120

    I have a funny with my D100 + D120 setup above. It is fed NMEA 0183 GPS data at 4800 baud from the 296. I used to feed it NMEA 0183 GPS data from my Garmin GPS III Pilot at 9600 baud. I used to get the winds aloft appearing on the D100 display. I do have the necessary OAT (connected to the...

    my 2 CHT gauges and Oil Temp gauge start to rattle

    A lack of information on your issue is the biggest problem. ::) Engine? Dynon kit involved?

    AP76 delivery

    Was the AP76 ever officially 'killed off'? It was the 3D / VNav version of the 2D AP74, wasn't it?

    GPS connection to D100 / D120

    Ignore this, I think. Just found the answer... VTG - Velocity made good. The gps receiver may use the LC prefix instead of GP if it is emulating Loran output.   $GPVTG,054.7,T,034.4,M,005.5,N,010.2,K*48 where:         VTG          Track made good and ground speed         054.7,T      True...

    GPS connection to D100 / D120

    Here's a quick question that has just occurred to me. If my Garmin GPSMap 296 is connected to my D120 / D100 (DSAB'ed together) then do they all have to be configured to the same units (knots or mph) for all the wind aloft etc calculations to work properly, or are the NMEA 0183 messages always...

    EDC10 Update?

    What is the Garmin configured to show? Track? Also is the Garmin configured to display true bearings or magnetic bearings? If it's for track and magnetic then of course the Dynon heading will be different from the Garmin track by the correction for the wind speed. In the first picture you have...

    Dual remote compass

    There are pictures of installations around the interweb that have the two remote compasses stacked one on top of the other. For example... http://www.vansairforce.com/community/showthread.php?t=25211 Not entirely convinced about the rigidity of the tie-wraps in the picture in the link, but you...

    D100 start up issue.

    Does the D100 have the internal backup battery option? How old is it? The battery, that is. I wonder if that had become excessively drained and was pulling a lot of current at the start of its recharge cycle. In your position I would pull it and take a look at it physically just to check it at...

    General discussion

    There's at least one thread on this on the PilotAware forum: http://forum.pilotaware.com/index.php/topic,819.msg9849.html#msg9849 Not tried it myself as I don't have a SV (got a D100/120/AP74 system) but I can say that the PilotAware (PAW) product is pretty good. I use PAW with SkyDemon.

    Thanks for that - I'll use the MS numbers.

    Source of DSub spares.

    I'll look for the colour coding on the male/female 'pin's then. I had been hoping to get the pins before opening the connector up! I was hoping that somebody knew the manufacturer and series as buying from an electronics supplier rather than an aviation one is normally a heck of a lot cheaper...

    Thanks for the input. Good quality connectors are not too difficult to source. Been there, done that but the pins don't fit into the Dynon's DSub receptacle! Interchangability and compatibility with my existing Dynon supplied ones is what I want to achieve, partly because of price (only have to...

    Source of DSub spares.

    Hi all. Quick question that is probably answered elsewhere but I can't find it. I need some spare pins etc for my Dynon harnesses as I have a couple of wiring changes afoot (change of GPS unit etc). I know the Dynon supplied connector are nice, high quality, machined pin, crimp stuff, but...
