    Did they still have PSM-6s when you were in?

    Yes, I like them, light grey, big old round metter on the face, loved them. Now, that was the age of the new Fluke meters, that there was some precisions.

    I knew of a few that got flight tested, or at least the air crews would give them back to us in debriefing . :lol:

    Excellent! Yeah, by the time I finished working there, they had all but vanished to the "bone yard" where all dead electronics goes, along with a few good planes too.

    I'm sorry I've been busy lately.

    Some important notes to consider:

    Remember ALL DECAs get 21v power, not just the ones connected to a PI. If they all pass DC along, that would be a mess... (Just ask SMOKE...)

    The HR21-23 definitely should not have both network ports used. I'm guessing the HR24 trials will also be that way for starters. I don't know if that will stay a strong recommendation or not.

    Sonora is overkill in a powered switched network unless you've really got some LONG cable runs. But it's your electric bill. :) (And yet another PI device.) :) :)

    Azarby, sorry. But there is only so much technology can overcome in a given week. :)

    At this point, two PIs are really the only way. One to power the SWiM, that is convenient to the SWiM part of the network, and one for the DECA--convenient to the networking part. Normally you should be able to hid the SWiM PI under/behind a receiver. And the DECA one, under/behind the network someplace.

    Cheers,
    Tom

    Uh, are you saying that I shouldn't be using both the network ports on the backs of my hr21's, one for incoming internet, and the other to connect a hr20?

    I hadn't noticed that before... I guess I need to get another switch... 16 port.. lol...

    I have actually been running 2 HR20-700's through two HR21-100's for ages now, since before we even started MRV testing... DO we know why they say not to use it this way? Did someone in engineering not ask programing when they added it or something? :D

    Tom,

    I guess it's time for that sticky thread in the main forum we talked about.
