Baro altitude not getting sent from AFS to Avidyne IFD

[vas4afs]

Hello,

I bought my RV-10 about 18 months ago with 2xAF-5600 and an Avidyne IFD540 Navigator. I had noticed that I have to manually sequence missed approaches which have an altitude restriction and recently figured out (from an IFD forum) that the reason is that my IFD is not getting a baro altitude and I am trying to figure out what I need to do to fix it.

It looks like the IFD can consume the baro altitude via ARINC (label 204) but I saw something in the AFS forum that indicates that the AFS unit does not transmit baro altitude via ARINC. That article was pretty old so I am trying to figure out if that is correct.

My plane apparently has the original AFS ARINC adapter. Will replacing it with the new SV-ARINC-429 adapter solve the issue? I have attached photos of the admin config pages from my PFD and MFD.

I had met Ken from AFS at OSH last year and when I mentioned to him that I wasn't seeing holds on my AFS unit, he said that the SV-ARINC-429 would solve that problem. I would like to upgrade to the new ARINC adapter especially if the baro altitude issue will also get resolved.

From a mechanics perspective, what do I need to do/be aware of to replace the old ARINC adapter with the new SV-ARINC-429?

Thanks,

Vas
