Um, unless I read the below incorrectly.  I'm not sure the wiring is
correct.

See www.cheltonefispilots.com for the specific wiring diagram that you
need... The way it should be wired is as follows.

FF -> Chelton (a Serial RS-232 connection)
FF -> TT (a Serial RS-232 connection, this can either be "Y"'d at the FF or
at the Chelton IDU, see the drawing mentioned above)
Chelton -> TT (an ARINC 429 connection)

I'm pretty sure that all the TT AP's want both an ARINC *and* an RS-232
connection.  ARINC is used for GPSS and GPSV (if so equipped), and the
RS-232 spits out NMEA that the TT will use as a fall back.

The FreeFlight is wired directly to the Chelton and the Chelton to the TT.
There is no direct link from the FreeFlight to the TT...so if the Chelton is
getting the GPS signal and the TT is not, the problem is between the Chelton
and the TT.

I am unable to get my FreeFlight 1101 to talk to my TruTrak Digiflight II
autopilot.  The TruTrak needs a GPS signal, and should be getting one

from the Pinpoint GADAHRS which is receiving the 1101 GPS signal.  (I am

not using the GPS on the Pinpoint)  The Chelton is getting the correct
signals from the 1101.  Is there anyone out there that has a similar setup
that is working?  (FreeFlight 1101, Chelton, and Trutrak)

Thanks,

Micah Froese
