I have a BM EFIS Lite G-3 in my Zodiac 601XL and a Trio Avionics EZ Pilot II
which accepts NMEA 0183 data stream. Below is an excerpt from my POH on
how it works on mine, and also with the Garmin 195 and 296. Note when using
the BM EFIS for AP data stream to my EZ Pilot II , I must have the EFIS AP
setting on COURSE BUG.
Hope this may help.

"GENERAL OPERATING INSTURCTIONS ON THE USE OF THE AUTOPILOT:
With The Auto Pilot turned ON
A. For use with the EFIS providing navigation (the
switch below the Autopilot is in the EFIS position):
1. Push the AP Button of the EFIS.
2. Select Source and scroll to and select COURSE BUG
3. Push the SET Button and select the destination and/or the Virtual VOR you
wish to go to,
4. Push the DSP Button and select the HSI.
5. Place the Course Bug on the of the GPS Destination or Virtual VOR Pointer
using the outer knob
6. Push ON the Servo Button of the Autopilot and the aircraft will turn to
and TRACK to the Course Bug Heading. The Autopilot should be in the Track
mode.
NOTE: The EFIS Course Bug is a heading Bug corrected for wind. In other
words, it determines the aircraft's track across the ground regardless of
the wind conditions. Be aware that in case of a crosswind, the nose of the
aircraft will be pointed into the wind and not to the selected course.
Rotate the outer knob on the EFIS to change the course Bug. While flying
the Course Bug, the Autopilot will list "BUG" vice a destination.
A. For use with the Garmin GPS 295 or 296 (the switch below
the Autopilot must be in the Garmin position and the switch below the EFIS
switched to either the GPS 296 or to the 295, whichever will be used to
provide navigation data.)
1. With a GOTO destination, via any waypoints as selected
on the Garmin unit, simply push ON the Autopilot Servo Button and the
Autopilot will turn to and track the airplane to the destination.

Subject: Blue Mountain EFIS to TruTrak Connection
I have been trying to find out if anyone has ever been able to make a
working gps
|
| Quote: | serial connection between a Blue Mountain EFIS and a TruTrak autopilot. I
have
|
| Quote: | made many phone calls and searched all the web sites.
According the BMA the G3 Lite will provide a gps output through one of its
two
|
| Quote: | serial ports in either GPSS (UPS GPS) or standard NMEA-0183 format.
OK.
According to TruTrak their autopilots will accept and read GPSS or
NMEA-0183 format
|
| Quote: | (with the correct baud setting programed into the autopilot).
OK.
Now here's the strange part. None of the tech reps at either company can
confirm
|
| Quote: | that their units will work with the other. Nor do they know if anyone
anywhere
|
| Quote: | has ever made a working connection between the two systems. I find this
very
|
| Quote: | odd that the manufacturers don't know the basic compatibility of the
equipment
|
| Quote: | they sell.
Here is my question for the List. Do you know or have you heard of anyone
who has
|
| Quote: | ever made a working gps serial connection between any Blue Mountain EFIS
and
|
| Quote: | any TruTrak autopilot? If so, I would love to hear from you.
