As typical of many discussions people throw out comments without
specific experience with the product. After reviewing many of the posts
here are my comments. First, the company was sold a while back and is in
the hands of some great people in Minnesota. I purchased mine from the
previous owners. I was working on an issue and contacted the new owner
(Tim) and he was 100% helpful. The previous people were great too.
Everything worked as it should from the first time the power was
applied. There were a couple of minor issues encountered that are
discussed below.
Someone mentioned the weight difference. I think in the overall scheme
it may add a little but so does failing to go to the bathroom before
flying!!!
It will handle ANY system. As far as upgrading, it is as simple as
adding the appropriate cable. There may be a chance you would have to
send in the hub, but not sure. How many people change out their panel
anyway. If you needed to can the who thing, this would be the cheapest
thing to replace anyway.
You get the complete wiring diagram and specific "pin outs" for each
cable. Not being familiar with this aspect of building, I found the
diagrams and pinouts easy to read.
I mounted the Hub just behind the panel (tip up) on the right side. It
is 100% accessible and looks very neat with the cables tied together and
running to the avionics. All of the cables have the computer look with
sealed connectors at each end. (except the audio panel at the avionics
end)
I figure I added about $400 to the overall cost of the wiring with the
system. The $400 was well worth the reduction of the BS factor on the
install. The install is quite simple with biggest issue being the audio
panel with lots of loose wires to find their homes.
I have the Pro G hub with the following equipment integrated with the
hub.
Garmin 340 audio panel
Garmin 430 GPS Nav/Comm
Garmin SL40
Garmin 330 Mode S transponder
Garmin 106A CDI
Trutrak Digiflight II VSGV auto pilot
ACK encoder
The only issues I had with the purchase was not know what the full
capabilities of the avionics I selected. As an example, I did not know
that I needed 4 unswitched audios for various components. The old
Approach Systems apparently did not either and didn't wire for these.
With the guidance of Approach Systems I was able to pin out a few more
wires. Also the Garmin 330 Mode S transponder has Density Altitude
capability if wired for a temperature probe. I did not know this. Again
I wired a couple of wires and it was done.
I spoke with the new owners about this. I recommended that they
conference with customers as to their equipment and the capabilities so
everything is wired as desired and the full capabilities are
experienced. Tim related they would do that. I should also point out
that their knowledge of individual pieces of avionics is exceptional.
Since they are an avionics shop the knowledge base is excellent.
In summary, if you are concerned about your ability to wire your panel,
simple or complex, do not hesitate use the Approach Systems product.
Despite the nominal extra cost you will reduce your wiring time 10 fold
with a system that works as it is supposed to.
Sorry for the length but I wanted to clear up some of the misconceptions
reported.

Thanks for the info....especially knowing it is real world stuff.
I think I could wire up the various cables....but why......at least for me
this is one area where i will error on the side of an expert.
I talked with Tim yesterday and he is a stand up guy. I will proceed with
the hub / cable system they provide and thank you and the others that have
shed some light on my lack of knowledge.

Subject: | Molex connector sexual orientation |
I was putting together some Molex connectors for the first time. The plastic parts
have a male and a female half. The terminals also are either male or female.
However, I am a bit unclear as to how to mate these parts. Intuition would tell
me that the male terminals go into the male plastic part. Yet, I have a feeling
it's actually the other way around.
Is a male metal terminal supposed to go into the male plastic housing, or the female
plastic housing, or doesn't it matter?
thanks,
brian

I bought a partially completed Lancair kit and the Pro-G Hub and several
cables came with the kit. I have since decided not to use it. It has
never been installed. I can make someone a great deal if they are
interested.
E-mail me off list and I will give you the details of which cables I
have, etc.

Subject: | ANR Headset Power without batteries |
I have a Telex Stratus 50D that I ordered with a "Lemo" connector (to use
ship's power) and battery pack as an accessory. This battery pack uses 6
each AA batteries.
My dilemma is that I own 2 aircraft (both tandem seating) and several
headsets (all ANR) and need to eliminate all battery packs. I have a strong
dislike of things flopping around in the cockpit. This dilemma seems to be
exasperated by the lack of a standard power voltage and connector to drive
the ANR in all headsets.
My questions are:
1) What voltage does my 50D headset ANR run on ?? The
specs in the Telex website differ from my actual unit in that my unit is
using 6 ea AA batteries. The website says this unit runs on 4 each AA
batteries. If it is running on 9 volts it will help my situation. I've
contacted Telex about this and am waiting for an answer.
2) One of my other ANR Headsets is a helmet with Headsets
Inc. ANR system that runs on 9vdc. I spoke with Headsets Inc. and he didn't
know what connector he is using for the power - would anyone here know ??
3) Does anyone have a sense of a "standard" connector
configuration emerging ??
4) I believe the connector configuration I will be choosing
will be:
a. Standard microphone connector
b. Standard headset connector
c. Similar style but different sized plug for ANR power - powered at 9
vdc.
This would allow each headset with this configuration to be used in any of
my aircraft; or any other aircraft with either no ANR or an auxiliary
battery pack to power the ANR. Would you please give me feedback on this
plan ?? Is it optimal ??
5) What power connector would anyone here recommend ??
6) Is there any other source for this magic Power Supply to
supply good 9 vdc ??
7) My wife has the Bose headset - I'm guessing it runs off
a different voltage given it uses 2 each AA batteries. What can I do to
make it fit into my scheme ??
My design goals are:
A) Inter-compatibility (or as much as possible) between my
headsets and my aircraft.
B) No battery packs in my 2 aircraft
C) Ability to allow anyone else with standard headsets to
plug into my aircraft (with or without their own ANR).
D) Ability to use my headsets in other aircraft not
equipped with my ANR Power plugs - using an auxiliary battery pack of my
own.
E) Keep all of my headset cords short with connectors
located near my shoulders (I have done this before and it works very well).
If this is of interest to anyone else I would be happy to post whatever
findings I come up with.

Subject: | Re: Molex connector sexual orientation |
Brian,
I believe that you can think of the male pins being protected by what
you call the "female" shell. The female receptacle pins are protected by
being internal in the "male" shell. So both are mechanically shielded by
their shells.
Hope this helps.

While technically it will work either way, the convention is that boys
go with girls. Your intuition is correct in this case.

Subject: | Re: ANR Headset Power without batteries |
I have Telex headsets, and they use a miniDIN connector into their
battery pack. I made up small connector panels for each of the headset
positions, placed them close to the shoulders as you described, and ran
a twisted pair to each. The twisted pairs all come back to an LM317
based power regulator set to provide 9V. Any headsets I purchase will be
9V compatible. I can add the miniDIN connector if it isn't there already.
4 AAs will be 6V I believe, and 2 AAs will be 3V. 1.5V for each cell.
But they may be wired in parallel within the battery pack, instead of in
series. Series configuration multiplies the voltage. Parallel
configuration multiplies the (capability to supply) current. It's not
save to assume. It would be relatively easy to set up the LM317 to
switch between regulating resistors, but you stand a STRONG chance of
ruining a very expensive piece of headset gear. If you must have varied
types of headsets, the real solution is to have construct a regulator
for each, put it in a tiny box that stays attached to the ANR power cord
and will then interface with ships power. You can set each headset to
what it expects.

Subject: | ANR Headset Power without batteries |
In my Quickie Q200 I installed Bose connectors and paralleled them up with
standard headphone/microphone jacks to allow use of either Bose powered
headsets or regular headsets. Works great but you need a battery pack for
other ANR headsets. If I did it again I would just install Bose connectors
and make up some short pigtails with a Bose male on one end and standard
headphone sockets on the other. You could add a power connector to the
pigtail for other ANR headsets. To deal with the stereo/mono issue I used
stereo headphone jacks with a few hundred ohm resistor in series with left
and right to allow use of mono or stereo headphones. IIRC this was suggested
by the intercom manufacturer.

Yes that is what I do.
In addition though I always arrange that the male shell (plastic
surrounds each female pin) is wired to the side that is hot (hardwired
to aircraft power). That insures that two pins can't be pushed together
and short out the power source. These are low cost connectors and that
can happen even sometimes while trying to connect the two halves.

<P>I agree with Ken, the male prongs can short if touched to something s

Larry,
I just received Jacks for my Headsets Inc. install from Mouser. If you wish to
isolate the ground you will also need .312 I.D. Shoulder washers. I didn't order
any and had to machine a pair!!
www.mouser.com

ORDERED STOCK NUMBER SHIPPED PRICE EXTENDED

Switchcraft L722A DC Jacks
PWR JCK LNG BSHG
"2) One of my other ANR Headsets is a helmet with Headsets Inc. ANR
system that runs on 9vdc. I spoke with Headsets Inc. and he didnt know
what connector he is using for the power would anyone here know ??"

Carl,
The jury is still out,I have not flown with the ANR conversion yet.
When I first turned them on in the shop the fan the was running
disappeared. It seems like they will work just fine. Headsets Inc
recommends there power adaptor, I believe I will brew my own although I
am planning on using a switching regulator. The converter they supply is
ground isolated and that is what I plan on replicating. The converter I
selected is on backorder until the end of April :( . The audio and dc
power share grounds so there is a chance of introducing noise into the
system using a LM317 locally at the jacks. I may try the LM317, it sure
is a lot simpler and cheaper (LM317's) live in my junk box!
The actual installation of the ANR modules was straightforward, the
hardware is well done. I replaced the cable with the optional cable that
they offer as I don't like the idea of the power cable zip tied to the
audio cable.

Can you provide some details of the ground isolated converter that you are
looking at - I'm just starting on the learning curve for the PCB type
stuff - would be good to see / try and understand how it could be done. $50
per 9V regulated supply seems a bit steep to me.....
Likewise I would go with a single cord - otherwise looks a bit 'amateurish',
and going DC Mono H10-13.4 to stereo ANR is attractive.
Cheers,
Carl
