Robertson AP11 Autopilot
74 20220513E
Compass setup
This menu item will set up the system to read compass
heading on the Robertson two-wire format or on Robnet
format. If a standard RFC35 Fluxgate compass or a magnetic
compass (via CDI35 Interface) is connected, the display shall
read “J3—“. If a Robertson RFC35R Rate Compass is
connected the display shall read “net” (Robnet). Activate
the COMPASS display by pressing the MODE button. Use
the < or > button to select the correct interface. Store by
pressing the MODE button.
Press > to proceed to next menu item.
Radar
The display will read RADAR. If your AP11 system includes
a J300X (not a J3000X) Junction Unit, you have the
possibility of connecting a Anritsu or a Furuno radar that do
not read heading signals on NMEA format. Activate the
RADAR display by pressing MODE. Use the < or > button
to select Anritsu (A) or Furuno (F) type of radar.
Store type of radar by pressing MODE.
Press > to proceed to next menu item.
Transition speed
The display will read SPEED. The AP11 provides two
different sets of steering parameters for controlling the
response of the boat at different speeds (HI) or (LO) while
in AUTO COM and AUTO NAV modes.
The AP11 always selects the HI speed steering parameters
when first switched on. This is a safety feature. After initial
turn on, selection of the steering parameters is done
automatically, based on the availability of input data from
either an external speed log or an external navigator
through the NMEA input port. GPS speed over ground may
also be used if a log is not installed. However, GPS may give
unstable speed information causing unwanted change of
parameters.
The speed at which the AP11 changes from HI to LO (or
opposite) is determined by the "Transition Speed" value as
set under this menu item.
