Aithre C0 detector

[jimRuttler]

Thanks all for helping. I saw this feed and assumed all was OK until Rhino pinged me.

If you can first verify voltage on the white wire unconnected to Dynon, you should see 3.3V for 60 seconds on startup and then 0V thereafter. If this is not the case, then there is a problem with the voltage output circuit on your unit and we can replace it.

Otherwise, if you are seeing the correct voltages, which is likely, then it is working properly.

The next step is to email me and I will send you a different sensor file from Dynon: jim@aithreaviation.com. Use an ENHANCED pin with the new sensor file and it will work. The issue is we have a few circuit boards that have diodes to protect against reverse current on the voltage output lines. Dynon's input pins have pullup resistors which prevents the diodes from working. So, Dynon was kind enough to provide a change that turns off the pullup resistor for the enhanced pins. We've since removed the diodes to avoid this issue.

I do hope to see Dynon add native support for the Aithre products - Don Jones how about it?

I installed mine last year and didn’t need any “secret file” from Dynon. Just followed the Dynon SV specific instructions from the Aithre website and downloaded the widget from their site. Set it up as a pressure sensor and that’s it. The last SV update cleared the widget but I just put it back.

This is an awesome pic. Love the digital DOT.

Jim,
Thanks for joining the conversation. I'll check your suggestion next time I'm in the hangar.

Meanwhile:
- I have the sensors wired to pins 10 (CO), 11 (SPO), and 12 (O2);
- few months ago, I switched my old EX to a new one that supposedly work with non-Enhanced (General) pins;

Questions are, will I need to re-wire to connect with Enhanced pins only, even with a new device of yours? Also, should I replace my Aithre module again?

Sigh. It's not a widget. All those arcs and graphs and numbers on your EMS display are widgets.

The thing you download from Aithre is a "sensor configuration file", which contains a set of sensor definitions, such as the Aithre CO monitor.

I guess you should take that up with Aithrie then because they refer to it as a widget on their support page.

After talking to Jim, he suggested me to re-wire the sensor to Enhanced pins and install the special file. Everything is working now.

A question on the Aithre Shield EX 2.0 installation as I haven’t found the answer in any other posts. When the sensor is installed and set up with the supplied sensor file does the Skyview system give an audio alert when the needle goes into the red zone?
Just trying to choose between the different sensors available currently.

 

[Rhino]

Yes, at 40 PPM I think.

 

[swatson999]

Yes, at 40 PPM I think.

Configurable...just set the yellow and red ranges to whatever you want, just like all other sensor widgets.

 

[Rhino]

Yeah, I should have said it defaults to 40 PPM (I think). Thanks.

 

[swatson999]

Whatever the default is for whatever widget you select...the only thing you get from Dynon is the *sensor* configuration to add to the .sfg file. The user has to then map the pin to the sensor, and then select the widget to display it. It's the widget that needs to be configured with limits. I don't what those are for specific widgets.

Just to clarify language...the *sensor* is whatever hardware you bought, and you use the sensor definition in the .sfg file (you may have to edit it to add the Aithre Shield 2.0 with the config info from Dynon and reload it) to select that hardware in the sensor setup menu (map the pin to the hardware). I'm sure you know this.

But what you "choose between" is not the sensor, but the WIDGET. That's from the Sensor Setup menu. and saved in the user config file, a .dfg file.

I see this misuse a lot...getting "sensor" confused with "widget" and vice versa. It confuses newbies who are trying to figure out how to configure their systems, to use the wrong words in the wrong places.

Thanks for the replies. My question was do you get an audio alert. I know with some widgets that there is no associated audio alert on the Dynon system so that was the reason for my question. I think I was quite clear that it was the sensor I was choosing between, Aithre, Flight DataGd-40 and others are in the running.

 

[swatson999]

Aha...I thought you had already purchased one (I was looking at the title of the thread). My mistake.

 

[chriscalandro]

I’m not sure why people are so lost on this and keep calling it a “secret” file.

It’s very clearly written in the install notes of the sensor….

I have followed this question up with Dynon and using the sensor definition included with the latest HDX sensor file Skyview will give an “ Engine Monitor “ audio alert when the needle goes into the red.
