GTX 345 ADS-B traffic working with any EFIS?

Postby GRT_Jeff » Sat Jan 12, 2019 12:13 am

I've had several customers ask about the GTX 345 and displaying any ADS-B In data from it. From the manual it seemed like traffic would be possible. I've told many customers what to try but haven't heard any success stories, and I've had a couple customers say they haven't been able to get it to work. Has anybody been able to get ADS-B traffic from this unit through either the RS-232 or RS-422 connection?

I finally have confirmed ADS-B IN traffic and weather data from a GTX 345 using its RS-422 output and an EFIS with RS-422 input. The baud rate is 115200 and the menu option in the 345 is "OPT LGCY ADSB".

It looks like you can connect this to an RS232 input using GTX345 P3252 pin 12 (RS422 B). We have heard this works.
