Subject: | Re: Hall effect sensors under the cowl? |
I have a dual LSE ignition with two hall effect sensors mounted right on
the engine. They even have LED lights on them. Can't get more forward
than that. I'm installing the AF 3500 too, so guess where theirs will be
going? I also have 13/8 with a second battery added to help make things
more confusing.
Just so we don't damage anything perhaps we can find out the upper limit
for operating temperatures on that sensor. If you are really worried but
really need to mount it on the firewall because of space or whatever you
could find a shroud for it and run a cold air scat tube to it.

The hall-sensor is an electronic device with
some temperature effects for both calibration
and upper limits for operating temperatures.
The automotive industry has been running
these critters under the hood for years.
I can't speak to the science for EMS
recommendations. I suspect the real risks
to satisfactory performance are insignificant.

I've found them. It's a collective document that
speaks to all the Z-figures and needs some work yet.
Z-14 though is pretty simple. Except for alternator
out conditions (rare) and perhaps engine cranking,
the cross feed contactor is OPEN. Under all other
conditions, each system is a stand-alone power
source that either is working (lv warning light
out) or not.
Assuming that there are electro-whizzies on the
aux bus that you really, Really, REALLY need
for comfortable completion of flight, then you
cross feed from the main bus to the aux bus.
If it's the fat alternator that quit, then you
close cross feed contactor and load-shed both
busses down to some value at or just below
100% load on the aux alternator.
This is an activity that you can practice
in flight.
It's pretty straight forward and not terribly
worthy of a special procedure in the emergency
check lists. Recall that our design goals include
maximizing failure tolerance and plan-A/plan-B
procedures that prevent any failure from becoming
an emergency.

Subject: | "Hockey Puck" GPS receiver that uses RS-232 |
I'm trying to find a low cost, low profile GPS receiver that speaks
RS-232 instead of USB. If anyone can point me toward one, I'd
appreciate it. Everything I find uses USB.
Background: I have a GRT Sport hooked up to a GNC300XL. Everything
works great, but the 300XL does not send the date/time to the Sport.
According to GRT, none of the panel mounted GPS's do (but all of the
hand-held ones will - go figure). This means that the time display on
the Sport is useless, and the Logbook function shows all my flights
taking place on 1/1/2003. So, I figured I'd just hook up a second GPS -
which the Sport supports.
I bought a GPS 'hockey puck' receiver and it works great on my computer.
When I hooked it up to the Sport, no go. When I asked GRT about that,
they said even though the GPS is sending serial data, it is speaking
USB, and the Sport only speaks RS-232. I got an 'RS-232 to USB
conversion cable" (has electronics to convert the protocols) but haven't
been able to make that work either. I did hook up a hand-held GPS
receiver I have (an old Magellan 315) to the Sport, and that worked just
fine, so I know what I want to do is possible, but I need a device that
uses the right protocol. Either that or help making the conversion unit
work.

http://www.byonics.com/tinytrak/gps.php
from their website.
===============
The GPS2 has a female DB-9 connector to connect directly to the
TinyTrak3Plus, is very sensitive, and is built with the SiRFstar III
chipset. It has the same DB-9 connector as the GPS1. It features Wide A
rea
Augmentation System (WAAS) to provide unmatched accuracy and performanc
e.
It has an on-board rechargeable battery for fast satellite acquisition
during power-up, and requires 5V to operate. Tracking up to 20 satellit
es,
the Byonics GPS2 can be used with almost every major mapping software (
NMEA
0183 v2.2 data protocol).
The GPS2 unit comes with a 6 foot cable, an internal magnet for versati
le
mounting options, and is water resistant.
It draws 65mA typically, and will work to an altitude of 18 km and spee
d of
515 m/s. Weight is 3.6oz. See below for more stats.
This is a 5 volt GPS. Do not connect this GPS to 12 volts or it will be
destroyed. If using with a TinyTrak3Plus, configure J7 for 5 volts (the
bottom two of three square pads soldered together). Do not use directly
with a TinyTrak3 (non-Plus). If you have a TinyTrak3, you need a GPAC o
r
GPAP power adapter below.
Byonics GPS2 - $69. The Byonics GPS2 employs the SiRF III chipset, sen
ds
NMEA data at 4800 baud, and is directly compatible with the TinyTrak3Pl
us.
Requires 5 volts DC. Pinout: 2 - Serial Out, 3 - Serial In (not normall
y
used), 4 - 5V Power in, 5 - Ground. Sends NMEA sentences: $GPGSA, $GPRM
C,
$GPGGA, $GPGSV.

Look at the garmin gps-12 range... Low cost and pretty reliable.
There's a 5hz version that spits out 19200 baud, which probably won't
work with most systems, so be careful! There is definitely an RS-232 9600
version in the list though.

Dennis,
I bought a RS232 to USB converter cable from Radio Shack to communicate between
my Dynon EMS and a laptop.? It never worked.? My son had one that did work and
didn't even require the installation of special software.? I don't know offhand
what his cable was, but I can find out if you want to go that way.

Before you hang whiskers on your airplane for
the GS receiver, try a coupler. Keep in mind that
ILS signals are beamed off the approach end of
the runway, only have to be functional for
perhaps 10 miles max and are VERY strong.
A VOR/LOC antenna is an odd harmonic relationship
with GS frequencies which makes it fairly efficient
for both services.
I'm 99% sure you'll find a single-antenna,
coupler-feed pair of ILS receivers quite
satisfactory.
