Technical Support / Re: Connect PAW with Powermouse
« on: August 04, 2020, 11:31:55 am »Following this thread I have found very interesting from the use of a Flarm display viewpoint and the connection of Rosetta to FlarmBat.
What I would like to know though has anyone tried connecting via RS232 Rosetta to a separate Flarm V3+display or the LX equivalent small display?
I suppose the question is, is the Rosetta protocol output compatible with the V3+?....this thread has suggested it just might be?
I've had a PilotAware integrated with an LX9070 moving map, Flarmview 57 traffic display and V3 alarm for a couple of years. The Flarm output from the 9070 goes to the PilotAware and to the V3. The PilotAware adds PAW and ADSB traffic which is then displayed on the Flarmview (a small traffic screen), and also sent back to the 9070 to be displayed on the moving map. I'm using RS232-USB convertors on both input and output of the PAW. I would expect that all the traffic would be displayed on Skydemon if I had one connected to the PilotAware (it's a glider, so I don't).
I put the V3 on the output of the Flarm (not the PilotAware) for two reasons.
Firstly, there are two types of NMEA traffic sentences in the Flarm spec. One is a traffic message, and the other is an alarm message (the highest priority piece of traffic which is likely to hit you). Flarm produces both types of message, PAW only the first - it leaves it up to the receiving instrument (such as SkyDemon) to make the assessment of whether the traffic is a threat. The V3 displays only alarm messages, so there's no point in attaching it to the PAW output. The Flarmview however, displays the traffic, so it works (though won't alarm for ADSB or PAW traffic sent by the PAW). However, I would expect a connected SkyDemon display to alarm on either.
The second reason is that I want to see Flarm alarms even if the PAW isn't working for some reason (that doesn't seem to happen, but I'm being cautious).
