I have recently received my EchoALT and got to work to determine what
information
it was passing to the EchoUAT over RS232. The format is NMEA and uses the
message $PUAVALT with Pressure (mbar), Temp C, Pressure Alt (meters) in the data
followed by a checksum (*#).
$PUAVALT,902.486267,34.292629,965.346741*41
High level, I use a python program to convert the pressure ALT to feet to send
to the GTX327 in Icarus format over serial.
This link is to the Uavionix document that goes over their NMEA messages.

I'd be happy to go over this in more detail if there is interest.
