All devices with traffic by TIS protocol so this one also.
I have tested on 696

Hi. A agreed with PAW developer and I sent protocol documentation them. I think they need a bit of time to look for it, identify missing items and make testing.

I hope it's on good way.

My idea is to build simple flarm (or something else) to TIS converter or get in contact with pilot aware team and implement it directly in PAW. This option would be the best.

Ok. So I did some work and I have dump of position reports sent in Garmin TIS by RS-232.
I attached this file and some screenshots.
Protocol is like described here:
http://www.garmin.com/support/pdf/iop_spec.pdf

So every sentence starts with 10 then 8C (packed id) then how long are data for eg. 48
then we have data...

on the end is checksum (AA) and 10 03

Maybe someone can help and analyze data section for lat/lon/altitude etc....

I know that garmin is using conversion's
degrees = semicircles * ( 180 / 2^31 )
semicircles = degrees * ( 2^31 / 180 )
 

Update!
After 2 days of research I found how to make it.
I have to decode some minor stuff but I'm able to display traffic by myself with altitude, direction, icon type etc..

This is GDL protocol. Can be similar or completly different.
I'll try to get somewhere tis-a transmitter.

I think only way is reverse engineering here .
Now I haven't any TIS messages trasmiter. Maybe someone can record some sentences from Garrecht TRX1500 of Zaon PCAS for analyze?
Probably I will have trx1500 next week but it's not 100% sure.

I expect that it will be normal RS-232 with 9600 or 4800 baud rate.

Hi. I'm looking for TIS protocol specyficatiom. I would like to decode it initially by arduino but then its easy to convert code and use maybe in pilotaware. Can anyone share some informatons, maybe specyfication of protocol?
I'm not sure if this GDL39 protocol is the same or not?

I have 496 and 695 for testing.

There is something. It's called Garmin TIS, normally it's used to connect with mode-s transponder. It can display up to 7 aircrafts.

Hi. It's normal RS-232. I know that XRX PCAS works with this via RS-232. I'll take a look.

Hi. It's possible to display traffic data from PilotAware on Garmin 496/495 gps?
