Adaptive Trim Tab System
Actuator power
Review section 5.5. Before you begin installation, you should:
• Know what power source you're using.
• Ensure the power source is suitable for the actuator power requirements.
• Have a plan to extend the power source to the stern of the boat if necessary.
• Have all the required circuit breakers/fuses, harnesses, and connecting wires.
Public NMEA2000 network
Connection to a public NMEA2000 network is required to get the following
features on non-Optimus systems:
• Holeshot mode
• Automatic tab retraction in reverse gear
On both Optimus and non-Optimus systems you will need a public network
connection if you want to display trim tab position on a multi-function display (MFD).
Review section 5.6. Before you begin installation, you should:
• Have the parts required to build a network or tie into an existing one.
• Know where the network power is coming from, if required.
• Have an NMEA2000 interface device for your engine (supplied by engine
manufacturer).

Step 2 — Install the private CAN network
The CAN network used by the Adaptive Trim Tab system is private, meaning that only
approved devices may be connected to it. Only components shown in this manual,
or in the Optimus EPS installation manual, may be connected to the network.
WARNING!
Do not cut or splice network harnesses.
5.2.1
CAN network fundamentals
The generic network diagrams in this manual cannot represent every possible
configuration and boat layout, so the network you build may look slightly different.
It will help to understand the basics of CAN networks as you install your system.
A CAN network is a communication bus with a trunk/drop topology as illustrated
in figure
