Hi John, I don't understand why you would want to use a c/b (in the power feed
line?!?) of the Trio where it has a pin dedicated that disconnects the A/P when
connected to ground.
I don't have the pin number readily available, but all you would need is a normally
open momentary switch that you can wire in parallel to the switch you already
have.

Jumpering 3/6 together will allow the LR3
to emulate a 3-wire, 'ford' regulator . . .
which is not necessarily bad . . . but it
fails to exploit a design feature of the
LR series regulators that improves regulation
performance -AND- wards off the 'galloping
ammeter' syndrome.

No, they wouldn't do that. The bus voltage sample
to the EFIS will be a straight pipe line from
sample point to the analog/digital converter.
But unless there is a separate input pin labeled
"bus sense" or similar, then the EFIS has no
choice but to monitor and display the voltage
applied to the system power pin.
In this instance, powering from the e-bus would
produced an expected, normal voltage somewhat
lower than main bus . . . not a big deal 'cause
you KNOW what the drop is.
As part of the experiment, you can CLOSE the
alternate feed switch for the E-Bus which
would bypass the normal feed path diode.
The voltage drops you observe on the field supply
are a separate issue . . . but related to the
overall investigation. However, when 3/6 are tied
together, then a voltage drop on that line would
fool the LR3 into believing that the bus voltage is
LOW whereupon the regulator would BOOST the
bus, not depress it.
So there are things we still don't know/understand
about your observations. Let's confirm integrity
of the regulator/alternator hardware first.

| Subject: | RS-232 and Navworx |
I am trying to use my GNS480 as the position source for my Navworx unit. The 480
is located at the top of stack and access is very difficult for running new
wires. I thought I could use a wire that is already going to my GRT for the
position source. The question is: How many RS-232 receivers can one transmitter
drive? I am trying to drive 3 receivers from one transmitter. Does distance
matter, since the Navworx unit is aft of the baggage bulkhead?
A grounding question: The Navworx unit has 3 or 4 signal ground pins, one of which
already goes to the 480, do I need another?

I sense that you are perhaps putting too
much weight on an a/p failure. First, the
the most likely failure is simple shut down
(quits and relaxes) or, if it uses stepper
motors, freezes up. The least likely failure
is a hard-over runaway.
Should a runaway occur, the first thing
you do is grab the stick and regain control.
The a/p is physically incapable of forces
you cannot manage manually. Once control is
achieved, getting it shut down is no big deal.
I would resist adding any more hardware or holes
in the panel just to effect a/p shutdown when
the event being managed is not an emergency.

| Subject: | Re: RS-232 and Navworx |
I'm not what I'd call an expert, but I think I can answer this one ok.
First, if you're using the 480, make sure that the intended
position source setting is what you need for the NavWorX.
I have not done this myself but it sounds like ADSB+, not
just ADSB. Bob Leffler probably knows best on this, and I'm not
sure if you would need to also be at the latest 480 firmware or not.
Bob, can you chime in and correct me or educate me on this part?
But, assuming it is the same data stream, you should be able to
drive all 3 receivers with no issue, if they are all uni-directional
connections. Distances within the airplane really won't matter,
as they really aren't *that* long. And, if you already have
signal grounds going to other pins, it's unlikely that you would
have a problem if you ignored it for that new additional wire.
You may still want to connect the shield, but the actual
signal ground will probably work just fine. I have a couple of
serial runs on my planes that don't have serial grounds connected,
for things like engine monitor data and such.

| Subject: | NavWorx software version |
We have a NavWorx ADS600-B box in our not yet flying Sportsman which Id like to
keep. We also have a GTN650, so that can be our position source. I understand
that is possible and that at least one person has received an Alternate Method
of Compliance approval from the FAA which allows certified Garmin boxes for
the position source. However, here is what Im not sure about. My question is how
do I rind the version of the software? And what version must we have in order
to fly using the GTN650 as the position source? We sent our box back to Bill
Moffitt (no charge, just UPS back and forth) in August 2016 at which point he,
I think, installed the GPS chip which we now know is not acceptable to the
FAA.
Thanks.

| Subject: | Re: RS-232 and Navworx |
One issue you may want to carefully look at (in addition to availability
of the ADS-B+ protocol on the 480); All the diagrams in the Navworx
installation manual that show the RS232 connection for the GPS source,
also have you connecting up 1 or 2 "Time Mark" lines. I also noted that
he 480 diagram for GPS source only showed an ARINC connection option.
There wasn't a diagram for an RS232 connection but I'm guessing you've
moved past that already.
I don't know exactly what the "Time Mark " line does but it's unique
to the GPS source connection for Navworx.
I have a G430w and (3) GRT HX EFISs. There is already a multi-point
RS232 GPS connection in my installation and it occurred to me to just
link the Navworx box to it just as you are planning. I agree with Tim
that it would not be a problem. But following the installation
diagrams. I was forced to go get that Time Mark connection from the back
of the G430, so I got a dedicated RS232-Out connection at the same time.
I would suggest investigating both availability of the ADS-B+ protocol
and that Time Mark line.

Hi Marcel
Yes: I've got the servo disconnect available ready for the pilots stick grip, my
thought is to put a breaker over on the right, so the copilot can have a 'disconnect'
(that side will only have a PTT).

Probably not. As you've discovered, this isn't a tightly
'calibrated' device. You CAN lower the switch point
by making small adjustment of the resistor in series
with the zener. Lowering the resistance will lower the
switch point.
The primary value of what you have now is a REPEATABLE
benchmark for tracking battery condition over its service
life. Irrespective of the exact trip point, you can
confidently assert that a battery that ran 2.7 hours
when new and runs only 2.0 hours now has lost 26% of
its capacity at the same load.

The NavWorx 4.1 software is the latest one available that I know of - it can no
longer be obtained from NavWorx - but it is out there
As for the GTN650 - make sure it supports ADS-B OUT+. You should be able to find
it in the serial configuration of the GTN650...or contact Garmin.

I am trying to use my GNS480 as the position source for my Navworx unit. The 480
is located at the top of stack and access is very difficult for running new
wires. I thought I could use a wire that is already going to my GRT for the
position source. The question is: How many RS-232 receivers can one transmitter
drive? I am trying to drive 3 receivers from one transmitter. Does distance
matter, since the Navworx unit is aft of the baggage bulkhead?
A grounding question: The Navworx unit has 3 or 4 signal ground pins, one of which
already goes to the 480, do I need another?

I tried doing the same thing with my 430. No go. The GRT is using the
"aviation" format and the Navwox is using ADS-B+. I am on a business trip
and do not have everything right now.....but I could not find a way without
running new wires. I think it will take me 2 days just to wire the 430
based on previous experience.

Thanks, Ralph,
So, how do I check the version of our software? As I said in the previous post,
we sent our unit back to Bill in late July or early August, 2016. Id suppose
he would have updated the software then as well as installing the GPS chip.
As for our GTN650 supporting ADS-B Out, thought all 650s would be ready for ADS-B.
Anyhow, Ill check with John Stark who sold us the unit, and if he doesnt know,
Ill get in touch with Garmin.

The 430/530 series and the 650/750 series did NOT have ADS-B+ format in
their original software. The original ADSB output had a few deficiencies
in the format to meet the final rule. When Garmin updated the output I
believe the FAA required they change the name of the output, hence
ADS-B+. You have to get the Garmin software update to get that output,
and then select it in the setup. I am familiar, because when I bought my
Dynon/Trig transponder it did not have that output format as a
selection. Had to get update to 650 and to the Trig to get everything to
meed the FAA spec. I expect the 480 also had to have an update to get
that format. I had to install a single wire from the Garmin 232 output
to the Trig position input.

Sheldon,
You do need to be slightly careful with terminology, RS232 is more the
physical method to connect boxes together defining connectors, pin-outs,
voltages and bit rates. The interface between them is a software standard -
such as NMEA0183 (usually just called NMEA). The interface standard will
define how the data is transmitted - what each transmitted bit means. A
typical RS232 chip will struggle to drive a cable greater than 50ft due to
capacitance issues, if your installation is approaching that length you may
have to experiment with different cables to find one that works - I have
only ever used cables a few feet long.
A NMEA bus can have several listeners, but must have only one talker - there
is no protocol for more than one box to talk. You should be able to supply 3
listeners. But be aware that strictly NMEA 0183 is not completely compatible
with RS232.
Should all the ground pins be connected together? So, no, you probably don't
need another. A circuit must be made for any databus to work, after all each
bit is only what the chip interprets as high (3v to 15v) or low (between +3v
and -3v) fluctuating at whatever the bit rate is (say 4800 baud - bits per
second). An RS232 bus should have a transmit, receive and ground/common
lines (wires). Whereas NMEA will only use either the Tx or Rx for each
device (so could make do with only 2).
All the details of both are explained pretty well on Wikipedia.
Hope this helps, Peter

Might be worth noting that NMEA0183 uses the EIA-422 (sometimes known as RS-422)
not RS-232.
Correct me if Im mistaken but EIA-422 is +5V for logic 1 and 0v for logic zero,
whereas RS-232 is -3 to -12V for logic 1 and +3 to +12V for logic zero, so entirely
incompatible.
RS-232 is differentially signalled

Dee,
For the GTN650, it should display the software rev at startup.
For the ADS600B, connect a serial cable to the maintenance port on the ADS600B
- the other end goes in to your computer/laptop/etc. Start the NavWorx UAT console
(4.1) and select the correct logical comm port for your computer. It may
not connect the first time - so retry another logical comm port. When it connects,
it will tell you what software you have or force an upgrade to the 4.1.
If it connects directly, it will tell you that it is 4.1 already.

And just in case you haven't already found it, here is the link to an
AOPA page that shows the various approved AMOC for the NavWorx AD:
https://www.aopa.org/go-fly/aircraft-and-ownership/ads-b/navworx-amoc-information
All three of the AMOC described on that page are for Garmin equipment:
GTN6xx/GTN7xx, GNC4xxW/GNC5xxW, and GNS480.
And in somewhat unusual behavior for the FAA, all of them are "AMOCs of
general applicability" so that any affected aircraft owner who meets the
requirements of the AMOC can use it.
Good luck to all the NavWorx purchasers!

One issue you may want to carefully look at (in addition to availability
of the ADS-B+ protocol on the 480); All the diagrams in the Navworx
installation manual that show the RS232 connection for the GPS source,
also have you connecting up 1 or 2 "Time Mark" lines. I also noted that
he 480 diagram for GPS source only showed an ARINC connection option.
There wasn't a diagram for an RS232 connection but I'm guessing you've
moved past that already.
I don't know exactly what the "Time Mark " line does but it's unique
to the GPS source connection for Navworx.
I have a G430w and (3) GRT HX EFISs. There is already a multi-point
RS232 GPS connection in my installation and it occurred to me to just
link the Navworx box to it just as you are planning. I agree with Tim
that it would not be a problem. But following the installation
diagrams. I was forced to go get that Time Mark connection from the back
of the G430, so I got a dedicated RS232-Out connection at the same time.
I would suggest investigating both availability of the ADS-B+ protocol
and that Time Mark line.

Thanks to all who replied. It looks like I need a 480 software update, some more
wires run, and a contortionist friend or a box of money.
I checked up and under the panel with a borescope and there are a lot of wires
directly in the way of the connectors I need to use, and then, there is the distance
problem of the 480 being on the top of the stack. This going to take some
serious time to complete.

Thanks to all who replied. It looks like I need a 480 software update, some more
wires run, and a contortionist friend or a box of money.
I checked up and under the panel with a borescope and there are a lot of wires
directly in the way of the connectors I need to use, and then, there is the distance
problem of the 480 being on the top of the stack. This going to take some
serious time to complete.

Many avionics trays allow the rear of the tray to be removed, or the
connectors removed, so that you can get them out to add/remove wires.
You do not want to make the connection with the connector in its normal
position.
Once I got the rear connectors removed from my GTN650, it was relatively
easy to insert the one additional wire I needed.

Thanks to all who replied. It looks like I need a 480 software update, some more
wires run, and a contortionist friend or a box of money.
I checked up and under the panel with a borescope and there are a lot of wires
directly in the way of the connectors I need to use, and then, there is the distance
problem of the 480 being on the top of the stack. This going to take some
serious time to complete.

Thanks to all who replied. It looks like I need a 480 software update, some more
wires run, and a contortionist friend or a box of money.
I checked up and under the panel with a borescope and there are a lot of wires
directly in the way of the connectors I need to use, and then, there is the distance
problem of the 480 being on the top of the stack. This going to take some
serious time to complete.
