Explanation

Measured rudder angle in degrees. S = Starboard, P = port.

Rudder command from autopilot. S = Starboard, P = port.

Compass heading

Measured turn rate in ° /min

Measured sine component of compass signal.

Reference for the sine signal.

Measured cosine component of compass signal.

Reference for the cosine signal.

Measured sine component of fluxgate signal.

Measured cosine component of fluxgate signal.

Measured signal on Follow-Up input.

Data readout directly from the RAM-address.

The AP45 software has a combination of factory set parameters related to the length of the vessel as displayed in the installation loop.

Selected	Autotrim	Counter Rudder	Turn	Rate of turn
length		Time Constant	Initiate
0-50ft.	48 sec.	1.0 sec.	30	240°/minute
40-70ft.	64 sec.	1.0 sec.	30	210°/minute
60-100ft.	80 sec.	1.5 sec.	25	180°/minute
90-130ft.	96 sec.	2.0 sec.	25	150°/minute
120- - ft.	96 sec.	2.5 sec.	20	120°/minute

In addition the COUNTER RUDDER values (magnitude) has the following scale: OFF = 0.0, LOW = 0.4, MED = 0.8, HIGH = 1.2
