new OAT installation

[dynonsupport]

That's truly bizarre. I'm not sure what you're seeing, to be perfectly honest.

Can you hook up the computer, use the "detect firmware version" option in the support program, and report back everything it finds?

D180 V4.2.0 (Serial #1448)
EDC10A V4.2.0 #6403
Sorry for delay but I had to buy a laptop and dongle as dongle supplied was not compliant with Vista

 

[dynonsupport]

Just a note, but if you are using the USB converter supplied by Dynon, it works 100% with Vista. The only difference is that you need to let it go out and find the driver online, not use the one included on the CD.

 

[brothwood]

My local IT genius tried that without success, so I bought one that works fine with Vista - It cost me $650 to obtain the info I supplied above - didn't own a laptop previously!
Anyway, any idead yet on the OAT?

 

[dynonsupport]

The reason this is really weird is that we never put OAT in a black box. It's in a white box when there is no OAT installed and you can manually set it. But upon boot it should say "OAT NOT SET" if you are in this mode.

In OAT installed mode, there is never a box, and it either reads the temp it thinks it is, or it says "OAT NOT FOUND"

Any chance you can take a picture and send it to us? We just can't get anything here that looks like you are describing.

 

[brothwood]

You converse with a computer idiot - pictures? I'll try!
I think the next thing is to check the cable loom for continuity- between the magnetometer and the D180 display unit - do you concur?George

 

[dynonsupport]

If you're seeing a heading at all that turns correctly, then those wires are connected correctly. The wires to focus on would be those between the OAT and the EDC.

There is another option here, though it's admittedly cumbersome. If you want to send your D180, EDC, and OAT, we can take a look at it and definitively figure out what you're seeing. I still think that we're missing something in our back and forth here though.

 

[brothwood]

Been off for a while - other jobs, now back with OAT. Checked all wires from EDC10A to D180 indicator plug. All OK. Unit still will not show OAT. Only indication is 00 in a black box. This indication appears when selecting type 1 or type 2 Sensors
Ideas please.

 

[dynonsupport]

Something's not adding up. The boxed OAT only appears when the sensor type is set to N (for not installed). In what exact menu are you changing the OAT sensor type?

 

[brothwood]

I have set it up in the EFIS menu as described in the instructions. When I select type 1 or 2, a boxed 00 appears. When I select None, nothing appears. The actual OAT is +9(Bit cool in this Hangar!)
I have tried warming the sensor probe but this has no effect - just a boxed 00.

 

[dynonsupport]

Can you take a picture of the boxed value while you're in the SETUP>OAT menu, with the OAT set to type 2? What you're seeing shouldn't be possible, but maybe we're missing something in our posts. Another approach - give us a call from the airplane at 425-402-0433, and ask for tech support. We can walk you through the menus to make sure nothing is being missed.

I've been on to Bob Howard of APS here in the U.K. He suggested I send the EDC D10A to him to fit into a known working system. This I did and he has just got back to me to say the unit tested out as servicable(damned expensive these tests!!)
In an earlier reply you stated that if the compass worked normally then the wiring harness from the EDC D10A to the main indicator was O.K. While the EDC D10A was with Bob I double checkecd the continuity of the leads from the EDC D10Aato the main display unit - all O.K.
When my EDC D10A arrive back with me I'll re-install and take some photos .
Regards, George

 

[brothwood]

Forgot to mention. What should the readings be across the wires from the OAT Sensor? I'll check them again. If I power-up the sensor with 5 volts, and cool/warm the probe can I expect to see a variation in the impedance of of what between which wires? Perhaps a small sketch will show me the correct method. Regards, George

 

[brothwood]

Just back from Hangar.EDC D10A not yet back from APS.
Powered up probe with five volts D.C.
Yellow to + 30.2KOhms increasing in value as probe warmed.
Yellow to - 35.7KOhms increasing in value as probe cools
Actual OAT in Hangar +10
Is this a clue? Regards, George

 

[dynonsupport]

Unfortunately, those values don't tell us much. When measuring resistance, you want to have no power on the probe at all. You also want to measure between yellow and blue. Here's the list of things to measure to check the probe:

With the completely unpowered:
Measure resistance between yellow/red
Measure resistance between yellow/blue

With the probe powered with 5V between red/blue:
Measure DC voltage between yellow/blue

 

[brothwood]

Have received back the EDC D10A after the check(perfectly serviceable, the man said) Fitted the EDC D10A and connected up - D180 reads"Remote compass not detected"! It worked fine before I sent it for check, so spoke to man who did the check - he confirmed that all he did was connect it to a working, proven system, and did not even open up the box.
Checked all four leads from EDC D10A to main display multipin plug - all O.K. Re-fitted EDC D10A - same message "remote compass not detected"
OAT Sensor
Unpowered resistances Yellow-Red, 9.78KOhms, Yellow-Blue, 14.5 KOhms.
Applied power to Red and Blue leads. Input voltage 4.86
Probe temp. 56F Yellow-Blue 3.00Volts
Probe temp, 90F Yellow-Blue 2.30Volts
The man who checked the EDC D10A is stumped and so am I

Those numbers look good. Looks like your OAT works.

At this point, we're stumped too. Given that your EDC-D10A worked when tested with another known good setup, and the OAT is basically measuring out OK, it's hard to imagine anything other than a wiring issue here, or some really odd bug that we've never seen before.

Again, we're more than happy to take a look at everything here if you're willing to ship the D180, EDC, and OAT here. In that case, we can check everything out on the bench.

FWIW - I'd be checking the wiring/connector at the EDC end.

Having exhausted all avenues, I am returning the FlightDEK D180 and the EDC D10A to you for checking. I have again checked the continuity of the Dynon wiring supplied with these units and all is well. I obtain 12 volts between Blue/white and Earth(White) and the other two wires prove continuous circuit.The testing of the EDC D10A has cost me $130, but I'm including it for checking anyway.I have already checked the OAT as you recommended above and this unit is virtually impossible to remove - unless you know someone 2 feet tall with 5 foot arms! Regards, George

 

[dynonsupport]

Give us a quick call at 425-402-0433 to get a return authorization before you ship your stuff out. Ideally, we'll want to see the OAT too, just to be able to fully replicate your setup.
