You have to use a 6 button KeyFob or an additional 2 or 4 button remote for controling Auto/Standby function. # Caution: Lighthouse III does not react on Seatalk Alarm -MFDs with Lighthose II will react on the Seatalk alarm function wit a short beep. Unfortunately Lighthouse III is ignoring this alarm.

Unfortunately, Lighthouse III is ignoring this alarm. If you prefer to use Lighthouse III then please connect an additonal buzzer to pin 20 of the ProMicro. # Software The Seatalk communication is a 9 bit serial protocol. This is not directly supported from Arduino. But I found a working 9 bit hardware serial implementation. For convenience, I have added the working source code here, because there are different versions available (in github and elsewhere).
