"Proprietary" data will ensure a companies "stuff" won't be used IMHO. Sure. This has been well understood for decades . . . at least in my circle of colleagues. DO160, MIL-STD-704, and a host of other cooperative ventures by capable and cognizant practitioners of the arts made it possible for makers of Murphy's Flying Flivers to buy components from Black Boxes, Inc, and Generators-R- Us with a high order confidence for achieving seamless integration. All this in spite of the fact that airplane guys, electro-mechanical guys and electron- herders had no direct contact or collaboration with each other. The risks to elegant solutions rise when (1) new guys on the block fail to see the advantages of such standards and/or (2) the producers of standards become less collegial, less cognizant of the art and more dictatorial in their production of requirements. It matters little whether you're studying the operation of governments, schools, companies, or home owner's associations. A cooperative venture to insure free-market exchange of value amongst capable competitors suppling a needful customer base waving credit cards is the time honored, well proven recipe for success. Yes, there ARE examples of ground-breaking ventures that pulled off a successful enterprise that included some degree of creative destruction. But creating a new communications protocol in a community of well established and widely practiced protocols is like walking into a classroom offering to deliver the world's most spellbinding lecture . . . in Swahili or Gaelic. Fortunately, Dynon is a relatively small and I hope agile organization. If still lead by capable participants in the world of spontaneous order, they will see the light and make useful course corrections. In the mean time, the best thing we can do to help is offer constructive critical review and suggestions. It wouldn't hurt to include a small feint as well . . . make little motions that suggest the credit card is going back into your pocket.

I invested a lot of my time and both companies agreed to the common specification... including modifying their own protocol to allow for commonality. When Dynon production released their version, they added one field in the air data, making it incompatible with the Garmin version. Now, apparently they have changed the EMS data as well. One small victory is that each company uses its own delimiter and version number so it is possible in software to determine the format. What we need is an industry group that produces interoperability specifications. Unfortunately, our industry is too small to support such an effort, so it's up to groups like MakerPlane to produce open standards for EFIS data and such. One thing for sure, I will never donate my time to this effort again. Shame on Dynon and shame on me.

FYI -Matt) Dear Dynon Support, I was forwarded the text immediately below regarding the new Skyview Version 5.1 issue and EMS data stream compatibility with Vertical Power VP-200 I think that Dynon is kind of missing the point here. Dynon has, for all intents and purposes, developed a "standard" for this EMS data format. Whether arbitrary 3rd parties use it and/or communicate that use to Dynon is also beside the point. Dynon has committed to a certain format and as such cannot change it without incurring some serious, potentially negative and/or life threatening ramifications in the field. The designers of TCP/IP didn't just randomly decide to change the order and meaning byte values in the standard. A standard is a standard. When its done and released, *its done*. Version 1.0 cannot be updated. Adding a "version string" to the data stream doesn't work either as the devices listening to version 1.0 don't know the version string is there and are equally as broken. The only option is to version each new format and allow the user to select between the various version. Or, depending on the flexibility of the protocol, ADD new data strings to the format. But the original data strings *cannot* be changed. For example, in NMEA0183, $GPGGAxxx, $GPRMCxxx etc. allow for a progression of new formats to be added. But the format of $GPGGAxxx always has to remain the same. I work at a Government research laboratory in Livermore where I engineer and write embedded firmware for remote security terminals that are used throughout the Department of Energy sites. Part of that responsibility is to design, implement, and utilize serial protocols for communicating between various devices over both RS485 and Ethernet. If I were to make a change to our protocol like Dynon has done in the upgrade between 5.0 and 5.1, I would be fired. Plain and simple. Even IF everyone that is using the protocol happens to be notified of the change, there is still the issue of incrementally upgrading all of the end devices. I guess my point here is that Dynon needs to take their various "proprietary" serial protocols a whole lot more seriously. I believe this is now at least the *third* time that a protocol change has adversely impacted the user community. That is *not* acceptable. I would have probably been fired after the first indiscretion, if not strongly reprimanded. The second and third times would just not have happened. For protocol versioning control, Dynon needs to either add additional named strings to their protocol or they need to simply start versioning each change AND including support for all versions in their products. For example, the user should be able to select between EMS Version 1 or EMS Version 2 or EMS Version 3 from the configuration menu. The format of EMS Version 1 or any previous versions can never change; period. And finally, given Dynon's lackadaisical attitude toward their protocol specifications, I find it almost impossible to believe that a simple downgrade from Version 5.1 to 5.0 is, by default, disallowed? Why aren't the same Draconian version control practices imposed on the customers, applied to their software developers as well?

Jones" One of the "Rich-man's problems" involved in designing and selling LEDs is that the technology is moving so fast, just as one cool device is ready to sell, it is obsolete. Cree has recently announced a 200 lumen/watt LED and has published a reference design for an MR-16 design that is free to use and will almost instantly result in marketed products. Not to be outdone, Phillips-Luxeon has released their Luxeon-M which has an enormous output (but lower efficiency than the Cree device) and furthermore works on 12VDC. It apparently will produce >1000 lumens at 12V 1000 milliamps. This is especially advantageous because it needs no (or a minimal) power supply for 12-14.5V systems. As always YMMV. -------- Eric M.

They are available for different size wires. It seems the automotive ones are not plated, but rumor has it that the John Deere 57M7508 is. Thanks !

There is also a removal tool for them that was useful. Here is link to a website that has the terminals, blocks, and exctraction tool. If the link doesn't work, the company is MIH Industries. Hope this helps.

So many connectors and no good way to sort through them all. Does anyone know what terminal this is ? http://www.qenesis.com/Temp/terminal.jpg Thanks !

Just clean and tin your tip, then drag it acros s the bridged pins, pulling the bridge away. If there's a lot of excess sol der there, you may need solder wick, but be careful how long you dwell with t he iron against the component. As a previous post suggested, a little flux o n the wick will help to draw away the excess solder.
