The AXP340 installation manual page 13 lists IFD540 Trig ADS-B protocol as a baud rate of

9600, while page 21 (set up) shows the GPS line speed as IDF540 Trig ADS-B protocol of

38400 bps. What value will the dealer program as part of the set up?

9600 bps is correct. We'll be making that typo correction in the next rev bump of the doc.
