Yes, it seems to be a known issue when the MLB is installed and the reported pressure altitude is negative it causes this issue with APX and the GPS and then I think only if serial connections are used. If grey codes are used then only the GPS is dorked up. The 340 will report 64285 and the GPS will have some pressure altitude of 130k. While I have reported this to several people at Avidyne nearly a month ago with no response, I do know my avionics shop has been told Avidyne knows what the problem is. I'm not sure if 10.1.1.0 will fix it or if it is the MLB100 which should have yet another update out shortly. It really hasn't caused me problems until last week where a big "H" was over the area and I'd have this issue to nearly 500AGL.

Had a new issue not seen here. Earlier this year I installed an IFD-540 and and AXP-340 X-Ponder. Had a few issues with the IFD-540 that the SW patch that removed the AD fixed. On Nov 7th we installed the MLB-100. When I took off ATC said I was showing 64,000 feet and reminded me that although a Skylane is a neat airplane he doubted that I was at 64,000 plus feet. Could not troubleshoot it very well on the ground. After calls to tech support they said it was a SW glitch and that whenever the pressure altitude is below sea level it sends false info to the encoder. The shop shut of the port to the AXP-340 and everything seemed normal. However on the trip back, about 2 miles from my home airport, ATC lost my X-Ponder signal for about 4 mins and then it came back. I also checked the flight on Flight-Aware and it did not show any ADS-B data. Flight over to the shop showed it fine before the MLP-100 install. Anyone else have this issue? Will fly again next week to see if ADS-B is disabled becasue of the MLB-100 install.

The fault annunciation logic is not clear to me. I have seen those faults appear (and persist) even while both traffic and weather data are being presented to me on the IFD. There are three distinct faults that I have observed: Usually if the 429 data is lost, then I don't get anything from the MLB. For the first two indications, I might still get the data even though the IFD says I won't. (I know that this information doesn't help solve the problem yet, but more data can't hurt.)

I finally got out to test fly with the latest MLB100 firmware and no power cycle was required for it to communicate with the IFDs. [Good News] Also, I saw traffic and, though it jumps around a bit compared to the same info from a stratus, it is in roughly the right places as the few actual planes I saw. [More Good News]
I'm still seeing frequent yellow Traffic Sensor Faults on the IFDs. So, the faults and the jumpy traffic appear to be the remaining issues of note. I need to go back out with a safety pilot to capture stratus traffic vs. MLB100 traffic on video so we can see if the problem is real or perceived. |

It does. If you have MLB software version 4.0.8 then you won't need the power-cycle technique anymore.
My understanding is that this was an IFD issue, not an MLB issue. But I am not absolutely certain of that. David Bunin

Steve,
I see the announced mandatory SB on the MLB100 in today's email... Hopefully this will correct the C.B. re-cycling sequence problem between the 540 and MLB. . The MLB still doesn't appear to get the TFR's. When can we hope to receive TFR's in the FIS-B broadcast received by the MLB? . Also, any idea on release of 540 v10.1.1? I am looking forward to the Audio Panel attenuation of Standby-Monitor. Tom Wolf

Those symbols haven't really changed since 2011 if you look back through the older documents; however, all the new devices like the Lynx transponder and even ForeFlight seem to be using a different style symbol yet. Maybe it's just the velocity vector coming out of the directional symbols. Will the velocity vectors be added when the symbols are fixed or is that further down the road?

Ok, so that document answers my question. The symbols are different because they updated them for ADSB and have more differentiation than with the older TAS/TCAD symbols. I think we'll need a legend just to figure it out now. It use to be cyan, yellow, and red. Now it looks like different shapes for different things. Ahhh, progress.

From what I can tell AC 20-172 (Appendix 2) 11 Jan 2011 AC 20-172A (Appendix 2) 23 Mar 2012 AC 20-172B (Appendix B) 20 May 2015 is current http://www.faa.gov/documentLibrary/media/Advisory_Circular/AC20-172B.pdf I can't wait to see the surface symbols: boats and cars on the IFD :) Also they don't look like they've really changed since 2011, but they don't look like symbols I'm seeing others use either which I think is odd. Can the MLB/IFD do Designated Traffic (page 31)? Not sure how that is handled by ATC or others, but that looks like a neat feature. Edited by roltman - 03 Nov 2015 at 9:57am |

Question: hopefully the answer is simple because the marbles aren't very good for your teeth. Why is the ADSB traffic symbology different from TAS symbology? From a user perspective, do I care the source of the traffic? If I have the TAS/A, will I also have two sets of symbols?

1. Yes, that's still the plan. The Release 10.1.1.0 software of the IFD540/440 does not contain an aural alert for the MLB100 sourced traffic alerts (TA) but we definitely want to add that in a future IFD release. It will be extremely helpful.
2. IFD540/440 Release 10.1.1.0 does support standard TAS symbology for ADS-B traffic - that was faster to get the software done and approved by the FAA. We will definitely add the new ADS-B traffic symbology in a future release. We're almost required to do so which means that won't get deferred indefinitely. 3. The ADS-B traffic was actually included in Release 10.1.0.0 but we had to disable it via a special software trick. That has been re-enabled now as part of 10.1.1.0 and is usable now. (Technically, it's independent of 10.1.1.0 but I need to fill my mouth up with marbles to accurately explain the gory details). BTW, on/about 3 Nov, we're releasing a new version of the MLB100 software called Release 4.0.8. This addresses two issues in previous MLB100 software and we STRONGLY encourage all MLB100 customers to upgrade at the earliest opportunity. We'll send out a separate eBulletin on that topic to all customers and dealers in the next day or three.

Steve I am about to purchase a MLB100 for my dual 540 340 240 install and just want to make sure we are clear on what I should ultimately the unit to provide. From you previous response to SB Jim:
1. Provide an aural traffic alert - Is this something Avidyne is thinking about or is it going to happen. 2. Will ADS-B icons and information (GS, direction arrowhead, color coding N-Number) be displayed on my 540 or just TAS boxes with altitude difference and trend 3. If it did not make Release 10.1.0.0 then when.

Happily that is not the case. I've been holding off posting in this thread as we were actively working something behind the scenes as described in this thread: http://forums.avidyne.com/forum_posts.asp?TID=824&title=major-positive-development-with-adsb-traffic (As a side note, that kind of thing is ALWAYS going on behind the scenes and this time, it seems to have worked out well for all of us which doesn't often happen.)

I think I read it (or read it between the lines) somewhere on this forum. It would have come from one of the AviFolk here, so not sure if that's what you mean by "direct from Avidyne" or not. David Bunin |

ADS-B traffic was to appear in 10.1. There was an unexpected snag generated by a different interpretation by the FAA of some design elements. If ADS-B traffic were included in 10.1, 10.1 would still not be out. So it was pulled from 10.1, to get it out the door. Thsi feature, and/or other features may suffer the same fate in future, hence Avidyne is rightly shy about including a list until the release is pretty much done, at least that is my guess. * Orest |

You totally lost me on that one, Tony.
I've shipped many products, but none through the FAA process. I know its a mess so I'm not asking for a date. All I'm asking is if ADS-B traffic out has been assigned to a dot release of some sort and, if so, which one. It's called setting expectations and is good business practice. And thanks, David, for the update on 10.2 possibly having it. Is that info direct from Avidyne on a different thread I missed? Edited by TogaDriver - 23 Sep 2015 at 9:04pm |

Then you have no idea the crap the ACO has you do to put out a release in the name of public safety, If the ACO isn't working, then they cant look at your artifacts.

FAA Re-auth should have nothing to do with the planning process of a company's dot releases. My question is perfectly fair: I want to know in which release they plan to include ADS-B traffic since it is an important feature that I lost when I was forced to swap out my Garmin transponder for an Avidyne transponder.
I did not ask for an exact date as I realize that is, in part, up to the FAA's response time. But, it is perfectly reasonable to try and pin down in what release a major feature (ads-b traffic) will be supported. Frankly, knowing the plan is good business as it sets expectations reasonably and will actually REDUCE the amount of these posts since we'll wait for the named release and only complain if Avidyne fails to meet their plan. Not revealing a plan at all leads to fear, uncertainty, and doubt. |

As I understand it, there is a pending software 10.1.1.0 which does not include the traffic interface, and there is a pending 10.2 software that does include the traffic interface, but so far (wisely) no dates have been posted for either of those. It would be reasonable to expect that in the grand scheme of things, 10.1.1.0 will happen relatively quickly and 10.2 will happen relatively slowly. |

Steve or Simpson,
Any update on priority for a dual-band variety of the MLB100? I am in the shop, and we're going ahead with prewiring and even installing an antenna, but still leaving an "empty seat" for the box until a dual-band variety is available. Thanks much, |

Thanks, TogaDriver. That's the same information I had, just wondering if someone has the final MLB100 IM to compare against what I was given back in January when I was wired up (Simpson?). I couldn't find it online and got tired of trying to guess URLs for where it could be. I'm really just trying to plan an appropriate amount of down time to take the plane to the avionics shop. I envy everyone who has a descent avionics shop within 100nm. |

Traffic is sent from MLB100 via 429 and can be split to send to 2 IFDs. Traffic is not passed on the x-sync bus.
Weather is sent from MLB100 via RS232 and IS shared by the x-sync so only one IFD needs to be wired for weather. Info is provisional and from my shop based on their pre-wiring for my (future) MLB100.

Steve,
MLB100 Weather Information seems a bit limited. I only receive METAR and TAF, but no Sigmets, Winds Aloft, Lightning, etc. ForeFlight ADS-B Wx is subscribed to many more weather products. Can we expect more Wx products on the MLB/IFD540 subscription? Thanks. Tom Wolf

I thought the MLB100 sent traffic over A429 not RS232. That's why I had to pre-wire the A429 line to both units as A429 won't transmit over the cross-sync cable.
My MLB100 is sitting the back seat ready to be installed, so I'll know soon enough. Edited by roltman - 31 Jul 2015 at 6:27pm |

Waiting for the IFD540 Traffic Display, I have the MLB100 traffic (RS232) displaying on Aspen MFD. Once 540 legally able, and TAS"A" updated, will display TAS & ADSB on 540.

As I understand it, the IFD currently (at version 10.1) does not process traffic from the MLB100 over the RS232 data bus. I don't have mine wired that way. It does process the weather data from the MLB100 over the RS232 feed. |

Yes, looking forward to the "A" upgrade... best of both worlds, especially with MLB & TAS"A" each also capable of receiving Air-to-Air ADS-B on 980 & 1090 respectively.

Believe only one datastream will be accepted, at a time, the other will be completely ignored.
The TAS6XXA units will internally blend ADS-B/R input together with mode C, both received on 1090, and output a coherent picture. * Orest Edited by oskrypuch - 30 Jul 2015 at 7:31pm |

So, with both wired as you describe, with the TAS605 wired to 540 on ARINC429, and MLB wired to RS232:
Will an ADS-B target beyond the range of the TAS interrogation, and picked up by FIS-B on the MLB, still display on the 540 (lower MLB priority) as an ADS-B target?

The 540 will accept traffic on 232 and 429. Had a choice when I installed my TAS605. 429 is preferred.

Any timeline for MLB100 ADS-B traffic support?

Jake, Distinguishing the MLB100 from "other 429 traffic" seems to imply that the IFD is capable of processing traffic data from the MLB100 in a format other than ARINC429 (in other words over serial data). Is that true? I hope so because that's how I pre-wired my airplane, and I am in the process of redoing my installation just to add a 429 databus. I won't do that if I don't have to. I pre-wired for MLB-to-IFD on serial port #2. If I will get traffic and weather from pin 59, that would make me very happy. David |

Let me clarify one thing. My preference would be to have GDL wx on the IFD 540 and MLB traffic also on the IFD 540. The 440 would have neither. But that is just a preference, I am open to other configurations.

Thanks everyone for the replies. Orest has it correct. I want to send GDL-69 WX data to either one or both IFDs. I want to send only MLB traffic to either one or both IFDs. If I read Roltman's post correctly, that is possible. I wonder if someone from Avidyne can confirm that.

Orest,
Yes, that's how mine is pre-wired. MLB700 Wx to top box, MLB100 Wx to bottom. MLB100 traffic will go to both. MLB100 traffic runs on A429. A429 data does not go across the crossfeed channel so if there are two boxes both will need to have that A429 input wired up to both units for both to display traffic. Its been almost 6mo since I had all this work done so maybe I'm forgetting something else. Wx on RS232 for MLB700 and MLB100. I also assumed I could disable the RS232 port in Mx Mode and have the opposite box crossfeed Weather w/o rewiring anything. Steve, is there an updated or finalized install manual for the MBL100? Also correct me if I misspoke above. Edited by roltman - 24 Jun 2015 at 9:43am |
