position memory. To use this unit, configure the DigiFlight II’s baud rate to 4800 baud in the setup screen. This unit does not
provide GPS-NAV information, course guidance, or flight planning. Its sole function is to provide the autopilot with a
source of ground track and ground speed information to slave the autopilot’s internal DG function.
