CT7 Thruster Interface
PN 20350008
The optional CT7 Interface is highly recommended when the SP38 Autopilot System is being
used on a vessel equipped with bow and/or stern thrusters, or when the vessel is equipped
with Azimuth Drives (also known as Z-Drives) of various types.
The CT7 is specifically designed to be directly compatible with (and complementary to) the
SP38 system, in features, operation, and appearance. It connects directly to the SP38’s 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 SP38 system, and a
Rudder Simulator which is used when the CT7 is interfaced to Azimuth Drives.
The SP38’s SPU has built-in setup and operational firmware support for the CT7; the
firmware activates automatically when a CT7 is plugged into the SPU at the
J7 - T

connector.
See the CT7 Installation and Operation Manual for full details, and setup and operating
instructions.
