Rudder Drives and Interfaces
CT7 Thruster Interface

The optional CT7 Interface is highly recommended when the Commander P2 Autopilot
System

is being used on a boat equipped with Bow and/or Stern Thrusters, or when the boat
is equipped with Azimuth Drives (as known as Z-Drives) of various types.
The CT7 is specifically designed to be directly compatible with, and complementary to,
P Series systems, in features, operation, and appearance. It connects directly to the SPU,
with a dedicated cable that carries power and all control/data signals.
The CT7 can operate a number of different solenoid valves, including on/off and proportional
types.
It has standard-voltage outputs, current-loop outputs and optically-isolated analog outputs.
The CT7 also contains circuitry for interfacing an Electric Wheel to the P2 system, and a
Rudder Simulator which is used when the CT7 is interfaced to Azimuth Drives.
The P2’s SPU has built-in setup & operational firmware support for the CT7; the firmware
activates automatically when a CT7 is plugged into the SPU (at the
J7 - THRUSTER INTERFACE
connector).
See the CT7 Installation & Operation Manual for full details, and setup & operating
instructions.
