Re: Electronics questions for 2003 sm#380
In Peregrinus, we have two identical rotary switches, next to each other.
(1) The original switch supplied by Amel to choose between the rotary drive and the linear drive
(2) A new switch to choose between the Raytheon Type 300 autopilot and the B&G AC42 autopilot
Therefore, one can choose to drive with either of the following configurations:
(a) The linear drive in the quadrant with the Raytheon autopilot
(b) The linear drive in the quadrant with the B&G autopilot
(c) The rotary drive above the galley with the Raytheon autopilot
(d) The rotary drive above the galley with the B&G autopilot
The B&G autopilot is connected to the NMEA 2000 network.
The Raytheon autopilot gets data from the NMEA 2000 network, too, so it can get waypoint data from the B&G chart plotter, for example, but if the NMEA 2000 network were to ever die, the Raytheon has its own sensors, compass, and keypad controller and screen, so it would continue to function without interruption. We've field tested this by turning off NMEA 2000 in the middle of a sail.
Switching drives or autopilots is done on the fly. For safety, we simply ensure both autopilots are on "Standby" before turning any of the switches.
