Yeah......for a 750 as well....what on earth caused this stuff up? Clearly a design oops.
Any rumours Stein?
At first we all were of the same thought process...as in "WTF", but after using it awhile we've come to find those little modules quite brilliant. In fact nothing sort of a design oops at all. It's quite calculated and quite on purpose.
You see, if you remove the box, or update the software, or have it repaired, etc.. (which sometimes whipes out all your settings) it keeps all of your configuration data stored nicely inside the backshell. In the past, you either had to have photographs of all your configs, had a good record of all your settings, etc.. Now, if you pay attention you can pull out your unit, have it completely zeroed out and put it back in (or remove/replace with another one) and 'upload' all of your config data right from it's on backshell. It also will help in theft situation as well (since it won't work with one, and it's VERY hard to get one, that will cut down on the online quick sales where someone gets screwed).
Also, the same is true for the EFISes they make. We've also found this quite invaluable when replacing, changing, or troubleshooting. If all your configuration data is stored in the wiring itself, then it makes resetting your device SO much quicker. Basically, this comes from the heavy iron world where most of the avionics are true LRU's - it's just now filtering down to us small guys. For us little airplane drivers we aren't necessarily losing money when the airplane is parked, but with something big like a whale minutes can mean huge piles of money...so swapping stuff out and having the configurations easily update is good.
Yes it can be a pain upfront, but we've come to like the time and headache they can save down the road.
Just my 2 cents as usual.
Cheers,
Stein
