I ignored it because I couldn't find a full specification or manual for
the brick; however, I'd be surprised if it doesn't have the audio output
port, as it would seem to be even more useful on the brick than on the
portable. Perhaps the audio port is available on a remote display? Just
guessing, since I did not find the specifications


I reviewed the brick preliminary user manual. It makes no mention of
an audio output port. There is no audio output connector shown in the
pictures and no mention of audio output in any of the connector pin
outs. I couldn't even find any mention of audio alarms. The manual
is preliminary though.

It is my understanding that the alarm audio is provided by the
rectangular display that is an option with the brick. If that's true
then the audio alert is probably encoded in the serial data output(s)
of the brick. I am not aware that this display provides an audio
jack.

I highlighted that already in the original thread when the Brick
manuals became available:

It might have to do with the system architecture, where the brick does
the calculations, but the display needs to take care of the
presentation of the data to the user, visual as well as audio.

On the other hand, the Garrecht Brick TRX-1500 does have an audio
output (and an additional serial interface) in the D-Sub15HD
connector.

It is indeed a bummer that the PowerFlarm brick does not have this
feature.
As Eric said, most newer radios have great features to input audio
from other sources (and mix/switch it properly)

Now, I still have some hope:
In the current published PowerFlarm Brick documentation, on the DB9
connector, pins 1, 4 and 6 have not been described.
I am keeping my fingers crossed.
Hopefully someone from the Flarm team can shed a light.

Yeah, that would be a welcome and refreshing change!
