Connects to: AC80 board (in AD80, AC80A or AC85 Computer).
The AD80 board provides analog control of rudder(s) and thrusters in an AP70 and AP80

The UI_CTRL DIP switch is used to voltage control line.
• Set to READY, the voltage control line will be broken by a solid state relay contact when the
autopilot is not ready for steering (Power off and serious error situations)
