That baud rate does seem excessive, the equipment Im fitting seems to have a common
rate of 9600

max rates of 9600 - definitely slower than the 115200 rate from the SkyFX-EXT
GPS connected to the echoUAT. (that I wanted to use for adsb)

> I currently am not receiving aero-electric posts for some reason
The daily e-mail digest has not been working for me for a few weeks now. I e-mailed
Matt, and he said it must be my ISP filtering the e-mail as junk, but I have
checked with my e-mail provider, and this is not the case. I think it is a
problem at the Server end.
The digest has failed a few times over the last few years, but generally comes
back after a couple of week, but not this time. Has anyone else suffered with
this problem ?

My all time favorite system shut down warning
is the flashing, low voltage warning light. We used
to sell a kit that included a high intensity
led annunciator fixture. The instructions
suggested that the annunciator be mounted
in prominent location in front of pilot.
The FIRST thing you see when the BAT MASTER
comes on is a red flashing light, the LAST
thing you see is the same light just before
the master is turned off.
This configuration conforms to several
design goals for system reliability.
The obvious feature is timely and
active notification of a low volts
event. It gets pre and post flight tested on
every flight. It helps remind the
pilot to get everything shut
down before exiting the aircraft.

As Art says, you should be able to send the position data from the SkyFX-E
XT to both the echo UAT and the ELT by splicing into the GY wire. Check you
r ELT to make sure it will take NMEA protocol and 115200 baud input.
Of course, the cheapest and easiest solution is not to have GPS position go
ing to your ELT. Seems silly to have that capability and not use it but I'v
e seen lots of installs done this way.

Dave,
I am pretty sure that the ELTs all want GPS input via an RS-232 line, not W
iFi. (Except for the few ELTs that have internal GPS receivers.)
In my plane, I just spliced into the RS-232 line running from the GPS to th
e transponder (GPS TX pin to the transponder RX pin). I ran that line to th
e ELT RX pin.=C2-
As a computer guy, who always thought of RS-232 as bi-directional communica
tion, this seemed weird. I had to wrap my head around the notion that RS-23
2 is being used to broadcast information (kind of like an FM radio station)
so it works just fine to hook one device's TX pin to the RX pins on severa
l devices.

This year I hope to finish the build on the Wittman Buttercup I have been b

which is supposed to have GPS position input!
I=99m not familiar with RS232 usage (that=99s used between the
uAvionix GPS receiver and the echoUAT) but it would be nice to share/use th
at data-stream instead of adding yet another GPS receiver.
Is that possible? What about tapping into the WIFI GPS position data being
generated by the echoUAT?
I know, I=99m probably way out to lunch on this - but it seems there
ought to be a better way.

I too have a flashing light on the panel to indicate low voltage ("you left
the master on stupid!"), however I have still left it on. I get distracted
by someone on the ground as I'm getting out, or bright sunlight washes it
out, or I just didn't look - it didn't matter I still left it on! So I
built a small circuit using a PIC and programmed it to start beeping 30
seconds after the bus voltage drops below 13 volts. I like the audio alarm
that only goes off if I take too long to shutdown so I don't get used to it.
Besides, it was a fun project - education and recreation, just like the FAA
says!
