PostPosted: Mon Apr 02, 2007 6:58 am    Post subject: Wiring phone and mic jacks. Reply with quote

Can someone direct me to a location where I can learn about hooking up my
phone and mic jacks. The Tony Bingelles books seem to only have a diagram
which appears to be helpful, but there is no written info. I have the
shielded wire that Stein sold me and it has a a plain white wire, white with
orange and then a white with blue and of course the sheild. The PS
engeneering instructions give the schematic for wiring between the radio and
the intercom and jacks but not what each wire goes to or the makeup of what
each jack connector is. Basically what is the standard for the color codes
on the wire and which color goes on which part of the jack.

Thanks,

Well, since AC wiring wasn't what earned the money for my flying
addiction, this is an opinion. Wink
AFAIK, there isn't a color code associated with AC wiring ...... most of
the Cert'd planes use one color wire and some even use wire numbers. My
only recommendation here is to use the shield as a ground wire and
ground it both at the jack and the unit. Using the airframe as a ground
in your mic/audio wiring scheme will only invite problems later on .....
especially when the jack nuts relax a little. We're not worried about
noise coupling or ground loops here (at least I don't), but a good
ground return path. In a perfect world you should draw up a schematic
of your wiring harness, but if you find that too big a task at least do
a wiring list that has color (if you have different colors), wire size,
and what's connected on each end ...... which includes connector number
(J1, J16 etc) and pin number. If you have in-line connectors, such as
at the wing root, give them an alpha identifier that identifies where it
is ..... like W1 for wing connectors, F1 for firewall etc.

I don't know if there is a standard way that it is done. The best thing to
do is either check with the person that wired up your harness for the audio
panel and ask them. Or, you could use a continuity tester and pick one set
of wires and find out which pin goes to which wire, then use that info to
solder on the jacks.

Thanks,

I forgot I have that book. How do I keep all this stuff together. Parts and
accessories on one table and other stuff on another table. Parts upstairs
under the bed. The count get less than it goes back up again.
EEEEEEGGGGHHHHH!

Where have people put the pilot and co pilot jacks so that they are not in
the way of general opporations?

Lots have them on the panel. I put mine on the forward facing portion
of the seat box face, over by the sidewall, just above the gear leg
weldment arm that comes forward to the front floor footpans. If you're
going to leave headsets in the plane, this is a location that allows you
to keep the cords to the outside, and not be able to easily kick the
plugs either. There are lots of other good locations too.

One other bit of info that sorry Linn, but I'd disagree with. You said
to use the shield as a ground and ground it on both ends to use as
the ground conductor. One step better would be to use shielded wire,
using the conductors for the terminals of the jack, but to actually
use the shield as a shield, and shield it on one end only of the wire.
That way you're actually getting a true shielded wire run to prevent
noise in your headsets. When you use both ends of the shield though,
you're basically turning it into unshielded wire.

As you say, the PS engineering manual says to connect the shield only at the
intercom side. Tim, these other good locations, if you did it over again, is
there a better location than what you used?

I built a console underneath the panel and put trim indicators and
headset jacks there. But am not flying yet so can not speak to the
convenience of it long-term.

Not true. The internal wires are still shielded. One good example is
coax. The only issue with grounding the shield at both ends are ground
loop currents. There shouldn't be any 'noise' producing stuff behind
the panel to radiate anyway. Most of the older factory-builts didn't
have shielded wires ..... most likely for weight issues ...... and did
suffer from mag noise when the filters went south ...... but the
majority were rather 'induced noise' free. The electronics has come a
long ways and noise filtering is so much better that they aren't usually
a source for 'noise' anymore. I think the most common noise producers
were the strobe power supplies ..... but the noise wasn't radiated so
much as it hung on the 12V power ..... and really mucked everything up.

I liken the 'ground both ends' debate to primer wars. However, if you
do decide to wire the mic/audio stuff up with the shield grounded at
both ends, and you think that's causing a problem that you're having,
it's just one snip away from a reality check. If you don't want to use
the grounded-both-ends shield method, at least run a separate ground
wire from the jack back to the radio or audio panel.

Sorry John, "better" is a relative term...depends on your goal.
If you frequently remove your headsets from the plane, you may
want a panel mount option. If you like to have cords clear and
you have standard headsets, you may want the pilot's and the
co-pilots jacks both on the Left side of their bodies.
It all depends on your goals. Here's how I came about mine...
(have I ever told you I spent a LOT of time thinking about things
on my plane before I did them?)

I have Bose headsets with removable mic modules that can mount
either side. For my goal, I didn't want cords crossing
my body with a stick in the way. I also leave my headsets in
and connected and they use panel-jack power, so that means
I never have to unplug them normally. Because of the above,
I wanted a protected location. The gear weldment does that
well. I wanted the jacks near the sidewalls. The location
works for that. I mounted my copilot side mic's on the
RIGHT side of the headset. This means that in my plane
all 4 headsets plug into jacks towards the outside of your
body, and if you move or talk or look in the direction of
the other pilots or passengers, you have no cords, no
microphones, and nothing in your way, so you can reach
and climb and do what you want without disturbing the cord.
While that certainly sounds anal, I wanted it to be very
"smooth" in function. The only downside is with the
jacks on the outsides, you need to keep your cables
clear during entry. To fix that,I have headset hangers
just forward of the air vents, so the whole thing can hang
there away from your feet while you get in and out. This
whole design goal may not at all meet someone else's wishes...
or it may be way too nitpicky for them. It's just my way.

Similarly, in SCUBA training, for those of you who are divers,
you're always trained that weightbelt buckles have right-handed
releases, so they work right-handed either facing your buddy,
or from behind your buddy, or for yourself. When attaching
myseatbelts, I followed this theory and all of my buckles
are installed in the same orientation so that they're all
right-hand releases.

That's the cool thing about this whole project. You can
personally design things with whatever you feel your
ultimate goal is. Is my way "best"? Well, maybe to me,
but maybe not to you.....but I certainly am shooting for
whatever would be the best that I can do.

PS: John, Steinair has your shielded triple if you need it, or
alternatively B&C has it too for a reasonable price. It's nice
in that it's color coded so you can wire it consistently to whatever
color code you want.

In everything I have seen and heard, you want to isolate the jack from
ground by using the fiber washers to avoid ground loops. Using the first
and second conductor as L & R or as Mic and Key is normal with the shield as
ground (outside ring of jack). That is the way I have seen it done, I
think, but I know that you don't want to let your jack touch ground.

I do remember now that the shielded wire was a three-conductor wire
shielded, so the white was used for ground, orange and blue used for the
other two. Tim's comment helped me remember that. Don't use the shield as
ground and don't ground it at the jack or to the jack. Just ground it back
at the panel.

Jesse, that's a good point ..... the fiber washer part. That would be ideal. Can I get a few washers from you??? Razz . Lessee, two jacks X 4 seats ..... yup, 8 should do it.
In all my years in electronics, I've never seen those washers ..... but that doesn't mean that they don't exist, of course. Gimme a source and part # if anyone knows.

I presently have a problem with the mic jack on my Traumahawk. It uses the panel as ground, and the pesky nut keeps getting loose .... to the point sometimes it won't key and sometimes no mic audio. Sheesh. The next time I tighten it (probably the 4th time), it's going to get some loctite!!!

Linn,

Those washers are in stock at Steinair.com. I bought 2 types
of them, ones for the mic and one for the headset. You
can even buy them right off this link:
http://www.steinair.com/accessories.htm

I hate to say it, but when the manufacturer specifies that
you should use shielded wire, and ground it only at one end,
and use fiber washers, you're probably going to get the best
possibilities of trouble-free operation if you do just that.
Not only was that in the PMA8000 install manual, but back
when I installed a sigtronics intercom in another plane
they specified the same thing.

Sure, you're way will possibly work, and maybe even work
ok...but for the extra couple bucks, I'd rather build the plane
to the proper standard the first time and not have to worry
about figuring out the bugs later. It was *really* nice to
fire up the plane and so far not have any wiring related
issues to chase down. Those side fuselage panels are
a bitch to get off, too, so it wouldn't be any fun to have
to chase demons.

But, you're very welcome to wire it with plain speaker cable
using household outlets for jacks, if you want. Wink

Jesse, that's a good point ..... the fiber washer part. That would be ideal. Can I get a few washers from you??? Razz . Lessee, two jacks X 4 seats ..... yup, 8 should do it.
In all my years in electronics, I've never seen those washers ..... but that doesn't mean that they don't exist, of course. Gimme a source and part # if anyone knows.

I presently have a problem with the mic jack on my Traumahawk. It uses the panel as ground, and the pesky nut keeps getting loose .... to the point sometimes it won't key and sometimes no mic audio. Sheesh. The next time I tighten it (probably the 4th time), it's going to get some loctite!!!

Tim, this is getting a little out of hand. I wasn't really clear, I
guess. I don't want anyone to willy-nilly disregard the Mfgr's
instructions. Sometime in the past they may have had problems using the
shield as a ground path, and even though present equipment may not have
the same idiosyncrasy, the old cure remains.

What I do recommend is a ground wire from the jack ground to the unit
ground, whether it's a wire inside the shielded cable or or the shield
itself (for the adventurous) is up to the builder. I have done it both
ways with no ill effects. However, I'm not a purist all the time and
have used what wire I had on hand at the time. When doing the wiring,
there's enough different ways to 'skin the cat' that no one electrical
layout will fit everyones' needs. And that's a good thing. Whenever
you try to make one-size-fits-all, then you get trade-offs. As with any
custom installation, you may just have to see what works.

In this case, adding the extra ground wire adds weight, which affects
the economy of the aircraft ..... and all those little 'extras' add up.
My goal is to make most of the instrument panel and radio stack easily
removeable ..... which will mean extra connectors, extra wiring length,
and hose lengths. I really do hate trying to work on the backside of
the instrument panel while lying on my back in the front footwell. It's
one of my trade-offs.

Linn,

Those washers are in stock at Steinair.com. I bought 2 types
of them, ones for the mic and one for the headset. You
can even buy them right off this link:
http://www.steinair.com/accessories.htm

I hate to say it, but when the manufacturer specifies that
you should use shielded wire, and ground it only at one end,
and use fiber washers, you're probably going to get the best
possibilities of trouble-free operation if you do just that.
Not only was that in the PMA8000 install manual, but back
when I installed a sigtronics intercom in another plane
they specified the same thing.

Sure, you're way will possibly work, and maybe even work
ok...but for the extra couple bucks, I'd rather build the plane
to the proper standard the first time and not have to worry
about figuring out the bugs later. It was *really* nice to
fire up the plane and so far not have any wiring related
issues to chase down. Those side fuselage panels are
a bitch to get off, too, so it wouldn't be any fun to have
to chase demons.

But, you're very welcome to wire it with plain speaker cable
using household outlets for jacks, if you want. Wink
