If you have a powerboat, select
Low Speed
or
High
Speed
and adjust how tightly the rudder holds the
heading and makes turns at low speed or high speed.
If you set this value too high, the autopilot may be
overactive, attempting to constantly adjust the heading at
the slightest deviation. An overactive autopilot can drain
the battery at a faster-than-normal rate.
•
If you have a powerboat, select
Low Speed Counter
or
High Speed Counter
to adjust how tightly the rudder
corrects the turn overshoot.
If you set this value too high, the autopilot can overshoot
the turn again when attempting to counter the original
turn.
4
Test the autopilot configuration, and repeat steps 2–3 until
the autopilot performance is satisfactory.
Advanced Configuration
Advanced configuration options are not available on the helm
control under normal conditions. To access the advanced
configuration settings of the autopilot, you must first enable
Dealer Mode (

NMEA 0183 Connection Diagrams
These wiring diagrams are examples of different situations you
may encounter when connecting your NMEA 0183 device to the
helm control.

NOTE:
When connecting a NMEA 0183 device with two
transmitting and two receiving lines, it is not necessary for the
NMEA 2000 bus and the NMEA 0183 device to connect to a
common ground.
Only One Receiving Wire
If your NMEA 0183-compatible device has only one receiving
wire (Rx), it must be connected to the blue wire (Tx/A) from the
helm control, and the white wire (Tx/B) from the helm control
must remain unconnected.
