ADS-B Weather on Skyview

[BrentC48]

I was doing some flying yesterday with Skyview system.  I was getting TIS traffic warnings and everything seemed to work fine for about an hour of flying.  However, I cannot find any ADS-B weather in the system.  In the MAP menu I don't see any Weather label on the menu.  When I checked a local airport that I know publishes METARs, there was no WX tab.

A little confused.  1) If I am getting TIS traffic through Skyview should I not automatically get weather too?  2) Is there a setup step that I need to revisit?

Appreciate feedback.

Brent.

Start with...
1. Which Serial port is the ADSB module connected
2. Is the ADSB module sending/receiving packets
3. Is the ADSB modules powered?
4. Was it ever working or did it suddenly not

I think the very first question is if you have an ADS-B receiver in the plane at all?

You get TIS traffic from the transponder. The transponder is ADS-B OUT, but it isn't ADS-B IN, so it can't get weather or ADS-B traffic.

If the weather button and tab is missing, then that means you don't have and ADS-B receiver configured in serial setup. If you had that configured but another problem, you would have the buttons, but no data under them.

Thanks for the comments.  For clarity, I definitely have the ADS-B module physically installed (per instructions from Van's).  In previous testing I saw the module listed on the screen as being recognized by Skyview.  Now, I upgraded to the latest S/W (ver 7.1 I believe) a few weeks back and while I made sure the power to the AP servos was on, however I may have left the avionics power switch turned off.  If that was the case, then maybe the ADS-B mod was not configured when I updated the S/W.

Next time I am at the hanger I'll reconfigure the whole system again and confirm that the ADS-B module is fully recognized.  I understand from your comments that if/when that is done I should see the weather menu items on the ground even if they don't work until I am airborne.

The ADS-B module is not a network module and doesn't get updated with a software update, so that isn't it. Just go check out your serial port configs and see what you find.

I removed the avionics cover and confirmed that the wiring harness was installed for the SV-ADSB-470 module (it was).  Started up Skyview, ran the configuration again and the attached BMP screenshot file shows what is being detected. 

If there is an indicator light that is suppose to light up on the back of the module (similar the red one on the EMS module that flashes) then the ADSB module is not showing that it is powering up.  I just starting flying the aircraft two weeks ago so this was not tested before.

I purchased the unit through Van's Aircraft for my RV-12 last summer so all the wiring etc...was supplied and I installed everything per the plans.  S/N on the unit is 1572.

Should I return the module to Dynon directly for testing? Appreciate some direction.

Brent,
ADS-B is not a network device, so it doesn't show up in the network device list. You must manually configure your serial port for it.

It is also not powered by SkyView, it is powered directly from the aircraft power. The red light should be on any time it has power, and it needs to be really broken for there to be power but no light. Are you sure the module has electrical power, your fuse is good, and all the switches that need to be on are turned on?

First, thanks for the patience, I'm making progress.

Exchanged emails with Van's today and did some testing this evening. 

1) I did have the serial port incorrectly configured.  Went back to the plans and corrected that today for serial port 2.

2) Tested the wire harness with multimeter and confirmed that pin #1 in the 9 pin connector for the ADSD-470 unit has power (12 volts) when the aircraft is powered up.  However, as I mentioned before, the indicator on the back of the unit does not appear to be lit up when the aircraft avionics/SV are all powered up.  Am I correct to believe that it should be illuminated?

Below are screen shots first from the setup menu showing I think that while data packets are being sent there are non being received.  (I was running these tests while the aircraft was in my hanger - does this look correct?)

The second picture shows the map screen and the lower left shows that the ADS-B is "not found".

Should it be returned or do you have another solution?  Appreciate your feedback on this.

If that light's not going it's not powered up. Your screenshot confirms that SkyView's not seeing anything from the module either. One thing that people occasionally get flipped is pins 1 and 5 (and all the ones in the middle). If you pull off the harness and then hold it in your hand, staring at the gold pins on the male side, and have the "fat end" up, pin 1 is the top left. (The manual diagram shows it on the top right, and that's also correct as you'd be looking at it when working on the back of the male connector while dropping the wires into it from the back of it)

 

[BrentC48]

Thanks for confirming the pin location.  That is exactly where it is in my harness. The harness comes from Van's and I guess there was a chance it was defective, but that does not appear to be the case.

So it appears I have a dud unit.  I'll contact the warranty line and work out an exchange or repair.  Thanks for your help.

One thing I'd look at is whether or not the power and ground pins are fully engaged. The ADS-B module has a near-perfect reliability record. We're happy to take a look at it though if you'd like to send it our way. support at dynonavionics dot com or 425-402-0433.
